Multiple Monitor Support Possible via DisplayPort?

Q: Multiple Monitor Support Possible via DisplayPort?

Hi all,

In a few weeks (I can't wait! ) I will replace my laptop with the Surface Pro.

Right now, though, I have my laptop connected to two monitors: One via VGA and other via DVI. I'm running Windows 8 Pro x64, so this all works great.

So the big question is whether it is possible to have multi-monitor support via the one-and-only DisplayPort that is on the Surface Pro? If so, what--if any--additional hardware would I need?

When I'm docked at home and using my Surface Pro as laptop, I really need to keep the functionality of using both external monitors (one is 31" and the other 29"). I would really hate to go back to only being able to use one.

If you can provide any insight, I'd appreciate it.

Thanks!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

A: Multiple Monitor Support Possible via DisplayPort?

http://www.displayport.org/faq/

there are 2 options:

1) DisplayPort v1.1a hubs available today that allow you to connect multiple monitors to a single DisplayPort connector. Various output configurations are available for these hubs including DisplayPort, DVI, and HDMI.

2) you need DisplayPort monitors that support daisychaining. DisplayPort v1.2, supports monitor daisy chaining.
DisplayPort v1.1a displays are fully compatible with DisplayPort v1.2 PCs and graphics cards. A DisplayPort v1.1a display can be the last display in a DP v1.2 chain.
Here’s an example:
A PC with one DP connector is driving two monitors via daisy chaining. The 1st monitor is a DP v1.2 monitor with input and output connectors. The 2nd monitor is a DP v1.1a monitor. DP v1.2 PC—> DP v1.2 monitor with in & out connectors—->DP v.1.1a monitor.

I have the Lenovo G500 which has one each of a VGA and HDMI port. I'd like to connect both an external VGA and HDMI monitor, plus use the Laptop display. It appears that Windows will support this because it recognizes both monitors when connected, but, the display properties tell me to disconnect the 3rd monitor. Is this just not supported? Do I need to move to a USB-based video adapter to achieve this on this model? My other semi-related question is: has anyone had success converting from HDMI to a DisplayPort monitor? Thanks in advance.

Hi Bandolier2k,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to inform you that only one display can be connected using any one of the port and both cannot be activated at one time, and external device cannot be supported to display video.

I am working on a laptop using the laptop screen and a seperate montior. I am running Win2000 which I updated from Win98.

In Windows 98 I could toggle my f8 key and get my monitor screen on two monitors. The key was that the workspace was large and you could move say an internt page to one screen and say set a word page in the other.

With Windows 2000 I am having problems getting this function. The toggle still works, but the workspace is different. Waht is in one screen is in the other. I have tested all the different screen settings and wnet through the help functions on the software to turn on the second monitor and make it primary or secondary. The problem is that you cannot set up one large workspace and have the windows in each screen sized to appear like two seperate work spaces.

Several have commented that this problem was due to the montitor driver, but I don't think that is correct as the driver updates do not change anything. I have also called MS and tech support is no help what so ever. Does anyone have any thoughts.

Thanks.

I have a brand new netbook, running win7 starter, with an intel GMA 3150, I've raked about on other forums, but couldn't find any specific answers relating to my specific problem. The problem lies in that i can't seem to find an option to extend my desktop over 2 monitors.

I've been through, as far as i know, every setting, and i've even tried a few apps to make this happen, but to no avail. In the intel interface, it only gives me the options of 1 monitor, or a clone. And in the desktop properties> display it says 'monitor 1/2' or options of a single monitor. It's really quite upsetting, because my motivation behind buying a smaller machine was to be able to use a second monitor independently of the 10.1". Any Ideas?

If its not possible to do this with the GMA 3150, is there perhaps some kind of external graphics adapter that would allow this? Since its brand new i don't wanna go dicking about inside it. Thanks.

Hello,
I recently started to experience problems with DP 1.2 support on my Latitude E5440 with Intel HD 4400 graphics. At firs the monitors failed to show image when I docked my laptop. Undocking and docking again would then resolve the issue. But after a few days it failed to show image no matter what. After long hours of troubleshooting with drivers and firmwares and updates etc I discowered  that disabling the DP 1.2 from my monitor enabled me to get image at least to one of my screens (diabling can only be done when there is an actual image on the screen?! :P )
As I have now come to an understanding through multiple support requests that it is actually something that is not supported under WIN 10 with my setup.
My WIN 10 is an update from WIN 7. Could this be the cause that it was working in first place? I cant confirm it because it was some time ago but I started to use the DP 1.2 option when I had already updated to WIN 10.
Does anyone have an idea of such similar cases or have I been privileged to use something that was not supposed to work in the first place?

My setup:

I'm using a new ThinkCentre M720t as a home media server, primarily for high-quality audio streaming but could in the future be used for video.  I decided to add a Soundblaster Audigy RX 7.1 PCIe card to the system because it has an optical audio out connector (SPDIF/TOSLINK).  The sound quality is terrible; I'm getting a lot of static in the soundtrack.  This is true whether using the analog audio output or the TOSLINK connector which is suprising as the TOSLINK is just passing through digitally stored audio.  Anyway, this seems to be a known complaint with the card. So then I got to thinking:  Could I just use the Displayport connector from the motherboard as the audio output channel?  I can plug a Displayport-to-HDMI adapter cable into my home theater receiver, ignore the non-existing video info, and just listen to the audio.  Question:  Does the Lenovo M720t deliver the audio via this connection?  Any experience with configuring this?

Hi there. I am working with two monitors. The first is a ViewSonic VX2250wm LED monitor, connected to the desktop (Lenovo ThinkCentre M90p) via aDVI(in monitor) to Displayport (Desktop) cable. The card is an Nvidia Geforce 310. The second monitor is VGA. Every so often, the ViewSonic's signal goes out. At first I thought it was the DVI/Displayportadaptor, but upon getting a new cable the problem persisted. I then assumed it was the latest Nvidia driver update, so I rolled back. The monitor's signal returned for a few days, but then eventually lost its signal again. This process repeats every time I install an older driver: the monitor comes back, but eventually dies. I am trying to figure out what is the cause of this problem. AFAIK it cannot be the Displayport as the Geforce is compatible. I have concluded it must be the ViewSonic monitor. Any help as to what may cause this loss of signal would be appreciated. I have a feeling it might be because I have not used an 'active' adapter and only have used passive ones. I just wish this information wasn't so vague and hard to find.  Displayport hasn't really taken off that well, has it?

New monitors are the Dell P2319H.  After failing to both displays connected to an old Lenovo docking station they assumed that upgrading the docking station to the newer USB Gen 2 docking station would do the trick. But here's the problem, the dock's only connection to the laptop is USB-C. Which does not exist on this old Thinkpad laptop. I had a USB-C to USB-A cable on me and gave it a go. It powers the docks and all the accessories but of course not the 2 additional displays.  If I look up "recommended/compatible" docks for this laptop obviously this one is not listed. The new monitors only support HDMI, Displayport and VGA.  Any idea if this logic would work, USB-C to Mini Displayport cable (both male ends)? In my head it makes sense, but not sure if a single Mini Displayport port is capable of power 2 of these 1080p monitors. Otherwise my last option is to try something another dock.

Hi Everyone,

I am attempting to configure EyeFinity with 3 monitors. My graphics card, a PowerColor HD 6850 supports a maximum of 3 monitors, and it sports the following monitor outputs: 2 x DVI, 1 x HDMI & 1 x DisplayPort.

My 3 monitors are all the same brand (Dell) and model (U2212HM UltraSharp), they each sport 1 x DisplayPort, 1 x DVI & 1 x VGA connection.

As all of my monitors support DisplayPort I see no need for a DisplayPort adaptor, and I have connected my monitors as follows:

1). DVI
2). VGA by way of DVI Adaptor (this is because I am using a KVM switch)
3). DisplayPort

Ironically only the 3rd, DisplayPort connected monitor is not working with EyeFinity! I have manually set the connection on the monitor (through the monitor's menu) to DisplayPort. Further when I turn the monitor off and on I see the message: "No DisplayPort " - so the monitor doesn't "believe" that it is connected.

Windows (7 - x64 - Professional) on the other hand responds to the monitor being turned on and off by making the long "doo doo" sound that it typically makes whenever a USB connection is established! However this being said "Screen Resolution" item only ever reports that two monitors are connected!

Furthermore ATI Catalyst can only see two monitors connected - it sees one Analog (due to the adaptor) and one digital (as pictured below).

A:Can't get 3rd monitor to work with Eyefinity - it has DisplayPort!

DisplayPort can technically drive up to 3 monitors, but I am fairly certain that you cannot easily mix it's output with another digital output unless the video chipset can allow it (and this would be high-end, because DVI and HDMI are based on older technology and would require decent amounts of horsepower that a single GPU isn't necessarily going to be designed for). Nvidia makes some laptop video chips that allow splitting the signal between VGA and a DisplayPort port, but that's analog and digital, so it's a lot easier on the chipset than pushing 2 digital outputs at the same time (with content protection, scanning, etc. required by those interfaces).

The latest DisplayPort spec allows daisy-chaining of multiple DisplayPort displays on the same DisplayPort port from a video source, but to do so you need to purchase the requisite cabling or adapters to achieve multimon on the DisplayPort port and all devices along a DisplayPort multimon daisy-chain must be DisplayPort 1.2 spec or higher devices.

There are adapters that you can purchase that can take a DisplayPort signal and output it to multiple DVI endpoints (which could then be downgraded to VGA with an adapter on the DVI port), but you generally need to be driving the same monitors at each endpoint too which can be a pain.

So I've been using a monitor via DisplayPort through the past week with no issues. Suddenly today, I turn on my laptop and the port is no longer detecting any monitor at all. I'm willing to troubleshoot this using any links or advice provided, please help.

I've tried restarting my computer, plugging the port in/out, plugging my monitor in/out... this problem seemed to have occurred out of seemingly nowhere. Any advice is appreciated, thank you.

A:Windows 8 not detecting DisplayPort Monitor

Alright, figured it out.

I'm guessing, that I probably set my external monitor to deactivate before unplugging it. The next time I plugged it in, it wouldn't activate at all for this reason.

I solved this by switching the way it got input from my laptop, going from DisplayPort to HDMI. Then I reactivated the monitor, and was able to switch back to DisplayPort.

In my personal opinion, this is truly the most idiotic thing I have dealt with so far in Windows 8. Hopefully display options such as "deactivate" don't stick around after unplugging them in the next iteration of Windows.

There is a feature on newer motherboards in which they have sleep state settings outside the control of the operating system. Go into your bios and go to APM configuration.

My 3 monitors are all the same brand (Dell) and model (U2212HM UltraSharp), they each sport 1 x DisplayPort, 1 x DVI & 1 x VGA connection.

As all of my monitors support DisplayPort I see no need for a DisplayPort adaptor, and I have connected my monitors as follows:

1). DVI
2). VGA by way of DVI Adaptor (this is because I am using a KVM switch)
3). DisplayPort

Ironically only the 3rd, DisplayPort connected monitor is not working with EyeFinity! I have manually set the connection on the monitor (through the monitor's menu) to DisplayPort. Further when I turn the monitor off and on I see the message: "No DisplayPort - so the monitor doesn't "believe" that it is connected.

Windows (7 - x64 - Professional) on the other hand responds to the monitor being turned on and off by making the long "doo doo" sound that it typically makes whenever a USB connection is established! However this being said "Screen Resolution" item only ever reports that two monitors are connected!

Furthermore ATI Catalyst can only see two monitors connected - it sees one Analog (due to the adaptor) and one digital (as pictured below).

Any help with getting my 3rd monitor will be greatly appreciated. I have considered uninstall... Read more

Try to make DisplayPort as primary Monitor and boot up from there make sure is it work first and then add each monitor on to the system ...

Hi all! I've got a question: my L440 (20AS) will not boot when I connect a monitor over DisplayPort to it - it gets stuck on the ThinkPad boot logo. If I connect the monitor while Windows is running, it works fine.The monitor in question is a Dell P2415Q, it's connected to the DisplayPort on the computer, which sits on a Basic Dock (the dock doesn't have a DP on it).Have tried playing with various boot/power settings in the BIOS, haven't managed to find a combination that works. Has anyone encountered/fixed this? Thanks and kind regards,Marin

My external monitor ASUS PB278Q stopped working. I switched out the DP cable which is newly purchased. I have my GPU driver updated and I'm pretty sure I've updated most other drivers on my laptop as well. I'm connecting the DP through the 433835U TP MiniDock Plus Series 3 (https://www.amazon.com/Lenovo-433835U-MiniDock-Docking-Station/dp/B0085MQLMQ). For some  reason the laptop doesn't seem to detect the monitor or vice versa. The monitor says DP cable no signal. Other inputs like the power adapter and the wireless mouse I attach to the docking station do work however. I'm not sure what else I'm looking at. I haven't tried using the other inputs like the hdmi (id have to buy an adapter) or the VGA and the one other one it has since I dont have cable for those... I'm not sure how to resolve this. Please provide support, thanks.

Basically my question is how do I change my default boot display to DisplayPort instead of DVI?
DETAILS
Looked all over and couldn't find a solution. My computer only allows me to boot up in DVI and nothing else. My motherboard and monitor support HDMI and DisplayPort but I've only ever gotten them to work as my secondary displays. In the past I ignored it because I had multiple monitors and could just use one with DVI and it would boot on that one and when it popped up with windows it would change my main display to the other one which was using DisplayPort. Now I only have one monitor and both DVI and DisplayPort are plugged in but only DVI will work. It is the same monitor that worked as a secondary monitor with the same DisplayPort.

I'm suffering from a creepy issue that my P50(E3-1505M, 16G non-ECC, M2000M) stutters while connecting with my external monitor (Dell [email protected]*1200) via the onboard mini displayport.It seems no problem while I connecting them via the onboard HDMI port, but if I connect them via the mini displayport (wether a miniDP-DP cable or a miniDP-DVI cable), the PC stutters while running 3D programs (like some 3D games), and, meanwhile, the CPU usage gets EXTREMLY high. I just want to know what's the issue probably be in this case? The Graphic card seems normal, and the mini displayport works, but how can a mini displayport connection makes the CPU usage high? Thank you!

I have a P52 with a P3200 with Max Q; I can use HDMI to plug it into my Dell S2417DG external monitor to use as a second display, but when I try to use a displayport-to-HDMI cable, the computer doesn't even detect a second monitor. The monitor already is on DP as it's input. I tried a USB-B to USB-A, also no dice. How can this be rectified?

I've tried several Displayport to HDMI Adapters to connect the displayport on mt ZBook 14 to my 27" monitor and the Top, Bottom and Two Sides are cut off by an inch or two, but the rest is fine. Has anyone had the same problem and found a solution OR does anyone have a proposed solution?

Hi all, I am trying to connect 2 external monitors (Asus VW22AT) to my W550S laptop.Via the VGA connection, it works fine (for both monitors, i tried one by one), the display automatically sets to 1680x1050 resolution. My problem comes from the mini displayport which i used with DVI adapter (I also tried with VGA adapter), I can't get the 1680x1050 resolution, it recommands to use a 1920x1080 resolution but the screen is blurred. If I manually set to 1680x1050, the image doesn't use all the screen, each side is black on 3 centimeters thus the image is also blurred. Do you have any solution please?Best regards, Jean

I just installed a dual-headed setup with the M700 SFF and two ViewSonic monitors that support DisplayPort daisychaining. I believe that the PC has the Intel HD 530 as a GPU. I can get video on each display, and audio to play on either display (including the furthest one that uses the DP pass-through on the first monitor) but not get audio to play on both displays. Has anyone encountered this / have a solution to suggest? In Windows 10 sound settings, I'm presented with each monitor as a playback device but can only choose one, and with Realtek High Definition Audio. Each option only plays audio through one display. Thanks,Kevin

Hello & thank you in advance for your assistance.

A month ago I installed a new Sapphire HD Radeon 7790 1GB DDR5 Dual-X OC GPU & began experiencing BSOD issues with driver atikmdag.sys. Would quite often go as long as a week between BSOD.

The BSOD seems to be associated with DisplayPort attached monitor. Have two monitors attached via Dual DVI which work fine. Can stream no problem. The third monitor which is attached via DisplayPort seems to be the culprit. Streaming The Mentalist on CBS.com last night on that monitor & it crashed right away. Watched Mentalist on another monitor with ease.

Have been working my way thru AMD Article Number: 27116 attempting to resolve this myself. Several driver versions with same results. Always use the AMD uninstall utility (restart), Driver Sweeper (restart) & CCleaner for good measure before installing next driver. BIOS is current as are Windows 7 updates. Have a 500W PSU, the GPU came overclocked from the factory & I did down clock for a short time which did not help. The GPU runs cool in the low 40's, the new PSU runs about 20 degrees hotter than the Dell OEM PSU. But it was crashing before with the cooler running 360W Dell PSU. Sapphire recommends a 500W PSU for this GPU even tho the 7790 uses less energy than the ATI Radeon 4850 it replaced.

Purchased a new SSD & this past weekend performed a clean install of Windows, went very well. Windows found all the drivers, even for the new Sound Card. The... Read more

A:BSOD while streaming on DisplayPort attached monitor?

Well it's a bit odd that I would come across this info now after a month and a half but - apparently there is an issue with the 20 pin on displayport cables. The infamous pin 20 issue.
To be fully compliant a displayport cable must not have pin 20 wired through.
The monitor is feeding power down pin 20, and the video card is feeding power out as well and the some video cards don't like it, (the power feed is to provide power to active converters, DP to VGA, HDMI etc.)

This thread is pretty close to mine:
How a Bad DisplayPort Cable Can Ruin Ruin Your Day
For about 2 months I've been struggling with a BSoD error related to atikmpag.sys on my Windows 7, core i7, 2x 5870 Crossfire system.

First, I assumed it was a driver issue. At the time I think the 12.1 Catalyst drivers had just been released. So, I rolled back to 11.10 or so. BSoDs continue anywhere from every couple of days to as often as every couple hours.I formatted my system partition and reinstalled Windows to try to fix.

Guess what? BSoDs continue!

Finally, after all of this, I decide on replacing the DisplayPort cable as the last possible point of failure. I should have mentioned that I'm running 1 native DisplayPort and 2 DVI ports. I replaced it with one from Accell off Newegg and it's been over a month without any further BSoDs. I've heard of plenty of issues out there with DisplayPort adapters, but never thought I'd have an issue with a straight DisplayPort cable distributed with a Dell monitor. Having... Read more
