Dell Latitude E7450 compatibility with E-Port Plus II with external Dual DisplayPort monitors

Q: Dell Latitude E7450 compatibility with E-Port Plus II with external Dual DisplayPort monitors

I have a Dell Latitude E7450 laptop with a E-Port Plus II port replicator connected to two external monitors using DisplayPort which will not output to multiple monitors.
I have another Dell model and when placed on the port replicator with two external monitors connected, booting into BIOS/UEFI the screen is cloned onto each monitor. However, when doing the same with a brand new Dell Latitude E7450 only one screen is active - the other is off. Within Windows itself, I can only have 1 monitor connected to the port replicator. If I undock, I can run 3 monitors independently indicating an issue with the dock rather than a hardware limitation with the laptop itself.
I believe the above tests eliminates the OS or driver issue and highlights a compatibility issue between the new Dell Latitude E7450 laptop and E-Port Plus II port replicator. I have tried this on 2 separate machines with the same results. I have also updated both the graphics drivers (Version, A16) and the BIOS (Version A04) to the latest releases. I have also tried using DVI cables as well as swapping out the port replicators. Nothing works. In Windows 8.1 itself, it actually shows as two monitors active, but one is not on. If I swap out the monitors to a different brand, I get the same result.
Is there a BIOS/UEFI setting I need to change? Is there a newer port replicator or update I need?

I have two U2715H monitors connected via one mDP->DP cable each to an E-Port Plus docking station (actually a EURO2 Advanced Port Replicator) in which is seated a Latitude E7450 laptop. All items are brand new. The E7450 is equipped with 16 GB RAM and two graphics cards: Intel HD Graphics 5500 and NVIDIA GeForce 840M; selection is automatic, which usually means the 5500 is in operation. It runs Windows 7 Enterprise SP1 (64 bit). The docking station apparently has DP 1.2a capabilities (for daisy chaining) but DP 1.2 is disabled in both monitors.
I have successfully set up the system to have the Windows desktop span both monitors at 2560x1440 resolution, even with the Latitude's internal screen as a third extension at its full resolution (1920x1080). The Main display may be set to either of the two (or three) and I can successfully move the sequence of the monitors around (left, middle, right).
So there is no doubt about the system's capability to support the intended configuration. However, when I dock the Latitude (mostly with the lid shut) and boot it, most of the time it cannot reestablish the configuration of the two external monitors. Some of the symptoms are: One or both monitors go black, indicating cable connected but no signal arriving from the docking station. If there is a picture on one of the monitors at startup, it may or may not contain the login screen. (I can still log in because I know what keystrokes to send.) If the login screen is visible, ...

A:Latitude E7450, E-port 2, U2715H - dual monitors - unstable configuration

No responses, so I will add my own, on the way towards a solution, which I believe requires driver enhancements. Are you listening, Dell?
Together with a colleague who knows better than me what to look for, we discovered:- The Intel HD graphics control panel -> Display port topology only discovers one, not two display ports. This could be a problem with the panel or with the graphics driver.- Both Intel and Nvidia have more recent driver releases for their respective hardware components in the Latitude E7450 than those available from Dell but they cannot be installed directly. (NVidia 353.06 vs 341.27; Intel vs - I suspect digits 5 and 6 reflect an OEM numbering scheme). Intel says their driver update includes critical fixes for display support.- When we attempted to install the latest Nvidia driver, the display flashed in what seemed to be a non-trivial manner (before the update was automatically aborted). This could be related to a conflict between the two drivers.
I also discovered that even when only one of the Dell U2715H monitors is connected, it frequently goes black when it shouldn't. So it is not a question of a dual monitor configuration as I originally thought. I have also swapped docking stations to eliminate random hardware error in this component. The Intel driver's handling of display port(s) seems to be the most likely culprit.
Guessing from seeing repeated patterns of monitor behavior, a more precise diagnosis could be t... Read more

Here is my situation,
I own a Lattitude E7450, and needed to connected two displays to it. I went ahead and bought the Dell E-Port Plus Advanced Port Replicator with USB 3.0, since it has 2 DVI ports on the back. It shows it is compatible with my laptop.
I set up my dock, connected my laptop, as well as both external monitors. Only one monitor shows a duplicated desktop. When I go into the display settings, I cannot see any existence of another external display being connected.
All of my drivers are up to date, restarted laptop many times. Pretty bummed out.
Anyone have any solution/knowledge to this?

I have a Dell Latitude e6440 (Intel+AMD video) with the newest BIOS A18 and the newest video drivers.  It is connected to an ePort Replicator 0PKDGR.   I have a Displayport cable connected between the ePort and an ACER 43" 4k UltraHD monitor at 3840x2160.
When I resume the Laptop from sleep/standby/hibernate, the screen flashes bars and sometimes completely turns off for a few seconds.
If I reboot, then everything is fine.
I've tried:

Making sure the bios and drivers are all up to date.
I had an unrelated issue about 2 months ago, and my motherboard and cooling fan were replaced.  So I'm assuming the motherboard is newer/better if there was ever a fix for this issue, but not entirely sure.   Since the Intel/AMD graphics are on the motherboard.  They were replaced.  The issues remained before and after.  
Tried turning off hibernate.  Using only regular standby.  Issue persists.
Tried turning off standby and only using Hibernate.  Same issue
It seems to happen more when the system is being used more.  Cooling fan runs more often.
Tried a different Displayport cable
Tried a different displayport connection on the EPort, DP1 vs DP2

Might be a coincidence, but I was just trying something and switched my monitor from Displayport 1.2 to 1.1.  The resolution of the display went down to 2k.   Then I switch back to DP 1.2 and the issue seems to have gone away.   I'm going... Read more

I recently started using the E-Port Plus Advanced Port Replicator with my Latitude E7450, but the headphones are not working.

Hello, everyone.
I am using a Latitude 3540 laptop with switchable graphics (Intel HD Graphics, AMD Radeon HD 8850M). As soon as I got the laptop, I upgraded to 8.1 (probably a mistake!).
All of my drivers are up to date according to Device Manager, and I've updated the chipset and BIOS and everything according to the Dell website. But for as long as I've had this laptop, the VGA port will not work! I'm using a VGA cord that has worked with other laptops before without issue. The laptop will not output to projector, external monitor, or a TV. Pressing the win-P combination brings up the ability to extend and duplicate my screen. When I change those settings, my screen resolution will change, but the external monitor/projector doesn't display anything. When I try to detect displays in my graphics properties, it just doesn't detect anything that's connected.
Is my VGA port faulty? Or does anyone have any suggestions on what else to try at this point? My laptop is still under warranty, so I suppose I could always send it in to be fixed.
Thanks for the help!

Hi Guys,
I just bought a Latitude e7450 and I am trying to use it with my PRO3X e-port docking.
I have found some issues but the most annoying one so far is the imposibility of using the Power button on the dock to start the laptop. The Power button is blinking (blue) but I cannot use it to power up or power down the laptop.
Am I missing any setting on my laptop? Is there a problem with my laptop? The docking worked fine for the past 4 years with my Latitude 6320 so I suspect there is nothing wrong with the docking.
I have installed the latest BIOS update today.
Thank you in advance for any suggestion.

I've got a C-level user who has a Latitude E7450, and E Port Plus docking station, 2 desktop monitors and a large, wall-mounted LCD monitor.  The E7450 has an Intel HD 5500 graphics card.  What he wants:

Laptop lid closed in the docking station off to the side.
Left-hand desk monitor as the primary.
Right-hand monitor as an extended desktop.
Wall-mounted monitor a clone/duplicate of the primary monitor (he uses it for meetings at his conference table at the other end of his office).

The wall-mount monitor is wired inside the wall to a wall plate with an HDMI connector.  It comes with a 6-ft cable with HDMI on one end (plugs to the wall) and DVI-D on the other.  He also had a short adpater connected to the DVI end with Display Port on the other which he had plugged into his old HP docking station.
The right-hand monitor is connected with VGA and the left-hand with DVI.
No matter what type of adapters or cables I try in various combinations, I am unable to get it to work as he wants.  We replaced his old HP laptop about 3 weeks ago and it worked fine in this scenario. (I didn't think about diagramming how the various cables were connected to his HP docking station.)  The HP used a DMS-59 connector for the left-hand (primary) monitor.
Some research on a Spiceworks forum lead me to think that my problem is both a display resolution issue (I understand that they should be identical, if possible), and a connection problem.  I had my supe... Read more

REFURBISHED (received this past Wednesday) LATITUDE E7450, I5 5300; WIN 10 8GB RAM 256 GB;
I thought I set things up correctly.
I can not adjust the first external u2415 monitor to DP1.2 'enabled'
When I try (with e7450 connected to first monitor and first monitor connected to second monitor), I get a pop up on the first monitor that I need to click on CONFIRM TO ALLOW THE CHANGE FROM DP 1.2 NOT ABLE TO "DP 1.2 ENABLED".
There is no way my cursor will allow that as the cursor is shadowed on the first monitor, and moves about,
Latitude E7450 rear mDP OUT --> mDP to DP cable -->

#1 U2415 DP OUT  -- > DP to mDP cable -->
 #2 U2415 mDP IN (DP 1.2 Disabled)

Besides doing it again, are there any further (very specific) instructions suggested?

I thought I updated all drivers and bios.

The e7450 is connected to DELL driver auto update link.

I have a Dell Latitude E7450 running win 10 that I connect to a Dell U2913WM using a HDMI cable. 
The computer used to show the correct display settings the last 10 months or so (extend the screen and use 2560 x 1080 on the external monitor) when I connect them. Since a few days however the highest possible screen resolution is 1920 on the external monitor and the computer never remembers the "extend" settings but rather use the "only use external monitor" option when they are connected.
I have updated the drivers for display, graphics card and rebooted a lot of times but still the same. I guess this is probably a Win 10 issue since its probably related to some update - but I still can't figure out how to solve this. Ideas?

I have a Dell Latitude E7450 that will not boot up. The power light turns on solid white and nothing else happens. The LCD doesn't appear to turn on, no diagnostic lights, no beep codes, nothing.
I tried to boot into the Dell PSA by pressing down the Fn Key + Power button, but it does not boot to it. In this case, the white battery charge light blinks at a steady interval, but nothing else happens.
I was, however, successfully able to boot to the LCD test by pressing D + Power button. It goes through all the different colors, then reboots to the same situation which I just outlined - power button on, nothing else happens.
I tried switching RAM, unplugging CMOS battery, draining all power from the system, etc. and nothing has been able to get this unit to actually post. Any ideas?
Thank you!

A:Dell Latitude E7450 No POST

Try with the battery disconnected.  If it'll power up that way, the battery is bad.  If it won't, there's not much more you can do short of replace the mainboard, which must be faulty.

Hi everyone!
I'm a happy owner of Dell Latitude e7450, i7, 256 gb, with discrete Nvidia card (Moscow, Russia).
Everything's great, I absolutely love the machine, but I did some hardware replacements after purchasing the laptop (3Y NBD warranty), including the display, because there were two spots with very noticeable BL bleeding effect:
However, the replacement display turned out to be much worse in terms that BL bleeding affects almost half of the screen, which is very noticeable when watching films or playing games:
I requested a second replacement, however, this time it was denied:
"Analysis of Field captures as well as service stock captures confirmed the light leakage is within Dell LCD design specifications, there is no defect with the LCD panel or assembly. Furthermore a certain light leakage is a normal phenomenon on FHD panels and due production and mechanical interference with the LCD bezel."
I asked tech support member why then they replaced it the first time as the display was much better, and he stated it was some kind of 'exception' (at that time they also replaced motherboard and cooling system as well because of the high-pitched noise problem) which is strange - either you have tech standards or you don't.
I'm very disappointed (as there's cleary too much bl bleeding) and I still want a display replacement. What can be done to achie... Read more

Hello, I'm wondering if it's possible to have a dual monitors on the HP ProDesk 400 G2.5 using both the VGA and DisplayPort at the same time. Will this allow me to extend the display to both monitors? If not, what will I need to purchase to gain this capability? Thanks,John

A:Using VGA in conjunction with DisplayPort for dual monitors ...

The VGA port and Display Port perform the same function just in different ways.  VGA is analog and Display Port is digital.  Unfortunately, it's not going to work the way you think.  You will be looking at the same information on two different monitors without the ability to drag and drop from one to the other.  In order to have a true dual monitor experience, you would need to purchase an inexpensive video card like the VisionTek Radeon PCI card which is specifically designed for this functionality.  This is due to the fact that the dual monitor ability has to be configured via the software that comes with the stand alone card. I hope this helps.

              We bought Dell docking stations D3100 to go with our Dell Latitude E7450.
I’m trying to configure the laptop for when the user disconnect it from the docking station, it automatically connect back to the network Wi-Fi.
Adapter Switching work great if I use the Ethernet adapter on the laptop itself. Once I disconnect the Network cable, it looks for the Wi-Fi and connects to it with no issue.
If I connect the network cable to the docking station, once I remove the connection from the docking to the laptop(usb3), I lose the wired network and it’s not even looking for the Wi-Fi.
I did configure the Dell gigabyte adapter on the docking station to be the first priority over the Wi-Fi just like I did for the laptop network adapter.
I updated the bios, firmware and drivers.
I also looked at the bios power management: Wireless Radio Control settings
Both local area network connections are above the Wireless one (priority)
Both Local area network adapter metric are set to 10 (only 1 is in use, both are set for testing purpose) while the wireless adapter metric is set to 9999.
As anyone had this issue or was able to get this working? Am I missing something ?

Hi, We have a dell latitude e7450 still under guarantee. The ssd failed (no boot volume)  so we sent it in to Dell for repair and, if required, data recovery. The diagnostics say the hard drive is good, so it appears that the MBR is bad but not the ssd itself? Dell have come back saying that they want to reformat the ssd or return the machine in its current state (unusable) so that we can -- according to Dell -- recover the data ourselves (how?) This doesn't make sense to me. When I complained that Dell should not use ssds that fail within 2 years of (mild) use, the Dell rep told me the only thing defective were customers who failed to back up their data. While it is true that there should be a way to create a bootable backup of the data, and I've tried using Dell's backup solution without success, it remains the case that the problem arose due to faulty Dell design/product choice etc etc. So I guess I am asking Dell to pull up their socks, own the problem and send us a restored working computer, but also asking the forum if they believe the Dell rep  when they said we could restore the data or are the ssds toast? We were also told the technical team has been looking at the problem but it required more testing and, two days later, our data is gone... Thanks for your advice.

A:latitude e7450 ssd failure, under guarantee, Dell refuses to acknowledge data loss

Dell is not responsible for data or data recovery - no manufacturer takes responsibility for it.  If you did not back up  your data, you're out of luck (and sending an SSD off for data recovery is likely to cost well over $1,000).

I am trying to configure three displays - two external monitors plus the built-in laptop display on my e6530. From what I can determine (based on my research so far), my configuration should be supported. Here are what I think are the relevant details:

Dell Latitude e6530 docked to an E-Port Plus replicator
Intel core i7 processor, with Intel HD 4000 graphics (up-to-date graphics driver)
2 external Dell monitors, both connected via a straight DisplayPort cable (not an adapter cable)
Windows 8.1

I have followed the instructions from the Dell knowledge base on configuring 3 displays on a Dell notebook with Intel HD 4X00 graphics, including the listed sequence of turning off the laptop power, then connecting to the dock with both external monitors connected.
I can get any combination of two displays working (I want extended desktop). This includes mobile display + Monitor1, mobile display + Monitor2, or Monitor1 + Monitor2. The Intel HD graphics control panel correctly recognizes both external displays as connected via DisplayPort. All three displays are recognized in both Windows and the Intel HD graphics control panel.
When I attempt to extend my desktop to the third monitor, it automatically disconnects the second monitor. I cannot get all three displays to be active at once. Like I said, according to all documentation from Dell and Intel this configuration should be supported, but it is not working for me. Any help would be appreciated!

I can get either monitor to work fine with the dock individually, but trying to run both simultaneously by extending or duplicating the desktop between them seems to fail as selecting either option under Display Settings just makes the primary monitor black out for a few seconds then come back - the secondary monitor stays black.  There's no error msg or popup that would help me investigate further unfortunately. I'm trying this with the T480's lid closed, and I'm running the latest 1.14 BIOS update and latest Intel HD graphics drivers.

As per the query we understood that you are looking for the details on screen resolution on your ThinkPad X230.
The maximum resolution for External monitor connected through DVI port is 1920 x 1200 on ThinkPad Mini Dock Plus Series 3, that means it will not support 3840x2160 resolution.

As mentioned in the title I have both pieces of hardware.  I also just purchased a third Dell U2414H LCD monitor.  I am trying to connect all 3 via display port.  However it seems that all I can do is 2 monitors?  When I try to daisychain them I got 2 monitors mirroring each other and one through HDMI off the laptop.

Is this a physical limitation of the replicator?  Is there a firmware update somewhere?

A:Dell Latitude E6520 & E-Port Plus 2 - Display port issue

The E6520 comes with Intel HD Graphics 3000.  The specs for that GPU are buried in the specs for the CPU itself, but if you go to ark.intel.com and look up your CPU, then scroll down to the graphics section and verify that it shows Intel HD Graphics 3000, you'll find that that GPU only supports 2 independent displays, which is why you see mirroring.  More recent Intel GPUs do indeed support 3 displays, but no Intel GPUs to my knowledge yet support 4.
If your E6520 has the NVIDIA discrete GPU, I can't find any information on NVIDIA's site about maximum number of supported displays, but based on your experience I would assume it's 2 unless indicated otherwise.

A:Dell Optiplex 3040 cannot use both HDMI port and Displayport at same time?

Optiplex 3040 onboard video out ports = HDMI, DP
A computer HDMI out port cannot up convert to a monitor DP in port via a straight cable. What you bought is designed to do the opposite; down convert a computer DP out to a monitor HDMI in port.
You would need to add an HDMI to DP Active Converter.
Computer HDMI out --> HDMI to HDMI cable --> HDMI in to DP out converter --> DP to DP cable --> Monitor DP in

Hi all,
Currently running a Latitude 5480 through a WD15 Dock. I have two monitors but can't get both to display. The dock itself has a number of connection options however it doesn't have two VGA ports. If I connect one of the monitors to the VGA port that works ok. If I use an adapter on the other VGA monitor to plug into the HDMI port on the dock it doesn't detect it on the Latitude.
Anybody successfully managed to get two VGA monitors to connect using the WD15, and if so how did you manage it?

A:Latitude 5480, WD15 dock, Dual monitors

Let's backup. What are the two specific monitor models? Link to the specific adapter you are using to try to connect the second monitor to the WD15. Read through the WD15 article, "How to Use and Troubleshoot the Dell Dock WD15".

Does anyone know if the Advanced E-port docking station for the Latitude E6400/E6500 supports dual DVI 22" widescreen monitors being used in extended mode ?
Apologies if there is already a thread on this but I find the new forum format impossible to search.  Any tips on how to narrow down searches would be gratefully received.

A:Docking station compatibility with dual DVI monitors

I have multiple users using dual DVI monitors and the docking station. At this time, I have only been able to get them up and running using one as a DVI monitor and the other as VGA.
Another post says to connect both to the DVI output, then manually configure the monitors to the DVI input using the monitors menu system. (Not the "Auto Detect" ), then with both monitors powered up, dock the laptop. I am trying this tomorrow.
Once the dual monitors are up and running, open the windows Display properties, select the NVIDIA tab, go to the NVIDIA console and setup your configuration as desired. Exit the console, then the Windows Display properties, and it should hold the configuration.

Ok.. I'll try to keep this breif. I bought this laptop SPECIFICALLY for the capability to run 2 external monitors via Thunderbolt 3. I have spent thousands of dollars on the laptop, monitors, and cables and put hours of research into making sure everything was compatible and it won't work.  My setup is as follows: Thinkpad T580 with TB3 portTB3 to Dual DisplayPort Adapter(x2)Monitors are both 32" Samsung 1080P monitors at 60hz (NOT 4k) Here's what I have done: Updated display drivers directly from Intel(newer than Lenovo provides)Updated BIOSUpdated FirmwareBought MULTIPLE adapters thinking it was possible an adapter problem.Bought MULTIPLE cables thinking it could be a cable problemI called Lenovo tech support and, after 10 minutes of convincing the tech that my laptop even has a TB3 port he obviously was unable to resolve it so I was mailed a new motherboard and a tech came to my house and swapped the board out. Same issue.  The laptop detects only ONE monitor at a time. If I plug them both in to the displayport adapter, one of them will work, the other will say it's not connected. If I unplug the monitor that is on, the previously undetected monitor will immediately be detected and turn on.  If I plug the undetected monitor into the HDMI slot it will detect and output. But this is NOT the functionality that I have spent thousands of dollars for.   I am out of ideas and now quite sure that, even though the marketin... Read more

Would like to attached dual monitors to my 5570 and EXTEND.  5570 has one HDMI and one VGA.
Monitors have one VGA and one Display port.

Processor is Intel Core i7-6600U Processor Base, AMD Radeon R7 M360, 2GB Discrete Graphics
As simple as using VGA out to VGA monitor one  and HDMI > Display port converter to monitor two.
Close laptop lid?

Or even better, is there a device I can always keep both externals plugged into then when I arrive only have to plug ONE cable into the laptop?  
Thoughts? Thanks!

I have a Latitude E7470 for work and when I first started using it with my docking station to external monitors, I was noticing a similar issue as was brought up in the thread linked below. One of my two external monitors (seemingly randomly) would flicker once, or periodically to a point where it was distracting. Additionally, I have seen the graphics card crash a few times after such problems appeared.

I implemented the "fix" that was linked (and marked as the answer to the thread) over lunch about a week ago, and more things went haywire from there. Basically, at this point I am unable to connect to any external monitors through the docking station. I have resorted to having a single monitor connected via HDMI, but it is hardly conducive to working and I would really like to have my multiple monitor setup back (even with the flashing problem, at the least).
Is there any way to undo the actions I have run, or is there a more up to date fix for this issue?
Link to "fix": 
Any response and guidance would be greatly appreciated. I'd really like to not have to resort to getting a different style (USB 3.0) docking station if I can prevent it.

A:Latitude E7470 External Monitors with Dock Problems

Yes I am referring to one of the external monitors flashing constantly when it resumes.  This has happened with previous Latitude models and you will see a synaptics VMM update within the video section of the 7450 that fixes this issue.

I have a Dell Vostro with one monitor output port. I'd like to get an adapter(splitter?) to plug two monitors into that will then plug into that one graphics card. Doing office stuff - word processing, excel, etc., - nothing graphically challenging.

I just don't know what the part that I want is called. And I'm making an assumption that this adapter would be less expensive than a dual port video card. Please correct me if I'm wrong. Any help available here please?

A:Dual Monitors - One Port

if i have read that correctly i think the item you are looking for is


which will split the external monitor port from your laptop into 2 ports.

there are also USB solutions to your problem. Google multi display adapters

I have just upgraded from an E6410 to an E7440. I have two Dell 2007FP monitors connected via DVI on an E-series E-Port Plus dock. The native resolution of these monitors is 1600x1200 @ 60 Hz and my old E6410 was able to run this just fine. The new E7440 however refuses to see that 1600x1200 is available and has an upper limit of 1280x1024 @ either 60 or 75 Hz. The Intel graphics properties app does show that 1600x1200 @ 60 Hz is a supported mode of the monitor in the Information Center section, but it won't let me select it in the Display Options section.
Anyone know if this is a fundamental limitation of the docking connector on the new 7000 series or if I just have something set wrong somewhere? All the drivers are up to date as far as the Dell support site is concerned ... The machine is running Windows 7 64 bit if that makes a difference.
Thanks & regards,

A:Problem with Latitude E7440, E-series dock & external monitors

Sorry - should have come back sooner as my IT guys at work found the "fix". This is a driver update that is for the E7440 but doesn't come up if you search for E7440 updates (???). Anyway, I got the required driver from:
Whilst the link is from the E5540 area, the driver is for the Intel HD4400 GPU that is in the E7440 as well. This has fixed the issue on all the E7440s we have here.

Is this the correct picture?  Google is showing me a simpler adapter without the USB portion (i.e. passive adapter).  I wish to be able to use this to connect my dual-link DVI only monitor that is 2560x1440 to my laptop (radeon 8750m) which only has VGA or display port.  Is this the correct adapter?  The description does mention 2560x1600, but I'm a little skeptical due to the differring picture results from my Google search.

I have an up-to-date computer built to run games very well. I want to use two monitors. They're both TVs that support being used as a monitor. The first one is the one I've been using since I bought the computer, connected via HDMI converted to DVI(i believe. not VGA, but still gets fastened by one screw on each side). The other, new TV that I bought, I am trying to connect via HDMI converted to DisplayPort, and nothing is registering or being found/detected

Hi all,

I have a Dell Latitude D630 and I would like to attach 2 external monitors to it and make one a default monitor and the other the extended with the lid of the laptop closed. The integrated video card is a Mobile Intel GMA X3100, and i have a port replicator (not a docking station).

What i've done is attached a dongle to the replicator, attached both external monitors, closed the laptop, and then both monitors are clones. I go into display properties\settings tab and select monitor number 1 to be default, selected monitor 2 and checked "extend Windows..." click apply but the "extend Windows..." selection deselects and goes back to original configuration.

Second try: I opened the lid to the laptop and sucessfully set the laptop as default monitor and "extend Windows..." to monitor "2" but both external monitors are clones. So essectially the system recognizes 2 monitors, one is the lcd on the laptop, and the second are both the external monitors.

I understand that the video card can only recognize two monitors therefore we will not see "3" monitors in the display properties. But i don't need the laptop and both monitors to work. What I'd like is to have my laptop lid closed, monitor 1 be the default, and monitor 2 be the extended, but the system is still seeing 3 monitors instead of 2 even with the lid of the laptop closed. Does someone know how to trick the system? Thank you in advance for your help... Read more

Hey all, I recently got a new laptop, dock, and monitors at work and am having issues with the 3rd monitor. Model are as follows:
1 - Dell Latitude 7480
1 - Dell D6000 Dock (2 Displayports, 1 HDMI port)
3 - Dell E2318H Monitors (Displayport and VGA input only)

The D6000 dock has 2 display port ports, as well as 1 HDMI. I can run 2 of the monitors successfully on the displayports, but cannot find a cable that will allow me to use the 3rd monitor with the HDMI port. I have tried restarting multiple times with lid closed, and also rebooting the dock by disconnecting the power.

I have tried both of these with no success:
HDMI to Displayport cable.
HDMI to active VGA adapter to VGA cable. (Adapter is a Startech HD2VGAE2)

FYI, when using the dock with an HDMI to DVI cable and older monitor, it recognizes the 3rd monitor correctly after rebooting the dock.

I need to convert to dual monitors on a HP 6200 Pro MT PC with Display Port and VGA ports.  The computer displays propertly with a single monitor connected to the VGA port.  Both monitors go black when I plug in a second monitor via the Display Port. In reading Internet documentation it is not clear if dual monitors will function from the system Display Port and VGA ports.  Forum articles address dual monitors with addition of a discrete video card (Big_Dave 2/4/2012). Will dual monitors work from the system Display Port and VGA ports?  If yes, what procedures are required to make such configuration work?  Any ideas on why the monitors go black?  Is a discrete video card required? Any assistance would be much apprecited as I ususally prepare income taxes and do not deal with bytes and bits.

I have two Dell uz2715h monitors. For some reason the second on that is running DVI to VGA (and I tried DVI to display port) is not working. The display port to display port works great. So we have to put in a Dell 2415 monitor in the place, which that adapter recognizes. Looks like an incompatibility with the Lenovo X1 Onelink Pro dock. THe latest FW and drivers are installed. Thanks!Gary
