Q: External Dual Monitors and Laptop screen issue EliteBook 840...

Hi, New EliteBook 840 G3 with discrete graphics and 2013 UltraSlim Dock using windows 10. I am using 2 HP Z23n screen, there are connected with 2 DisplayPort on 2013 UltraSlim Dock. I have 1 issues with this 1) My 2 external screens, connected to the 2 DisplayPort, started flickering then going blank and came back again without any flickering. Extremely annoying. Seems that the graphic card somewhat resets on screen or the other from time to time. Been trying to look at logs without any luck. Any ideas?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: External Dual Monitors and Laptop screen issue EliteBook 840...

Sorry, I can't help fix your issue, but I wanted to let you know that you are not alone! We have 7 Elitebook 840 G3's wth Windows 10 on the 2013 UltraSlim Dock as well, and they are all doing the same thing. Both external displays will go black for a few seconds periodically throughout the day. We are using HP EliteDisplay E242 displays for all except one user, who has ASUS displays, and they all have the same issue, so the display itself does not appear to be the issue. The VGA port seems to work fine, so this points to the Display Ports/driver being the issue. I have tried all available driver updates, but nothing has resolved the issue. We are looking for a solution to this issue as well.

The screen flickers for 10-30 sec to 5-10 mins. I saw a post which is the same issue for the 840 G3 laptops that was marked fixed by HP while it is clearly still a huge problem. Please fix this issue since we bought a huge number of these laptops and we are ready to return them if this issue is not fixed.

So i have a HP HDX16t with a 512MB Geforce 9600M GT video card running Win7 64bit Home Premium. The laptop has a VGA and an HDMI output. I currently have an external monitor (19" ViewSonic VX900) hooked up to the VGA output. Does anyone know if i can hook my second external monitor (also ViewSonic VX900) up as well through the HDMI port? The VX900 has VGA and DVI-D inputs, so i would definitely need an HDMI to DVI adapter (which i don't have currently). I have searched around on this, but havn't been able to find anything conclusive. Nvidia's 9600m GT page is sorely lacking in details.

I know i could set this up by buying a Matrox DualHead2Go adapter as well, but i was hoping to avoid spending an extra $200 that i would rather put into upgrading my aging monitors. Also the apparent downside to the DualHead2Go adapter is that i would need to place both monitors on one side of my laptop vs one on either side (as i had hoped to do).

I have a Dell laptop on a docking station running Windows 7. Everyday I place it on the docking station and use my 20 inch monitor. Is it possible to activate the dual monitor feature and use the 20 inch as the primary and use the open laptop as the secondary monitor? If so, what should my settings be?

The value of 'Multiple displays' (see attachment) should be 'Extend these displays.' You may have to switch the positions of the two monitors (at the top of that window).

Hi there guys, my name is James. I'm new to 7 Forums so please help me out!
In my work office I have dual monitors connected to a single desktop computer via DVI. I usually work both at work and home so I use my laptop alot. When I'm at home I need more desktop space so I bought 2 cheap monitors that only support VGA inputs. But because I'm using a laptop I only have 1 VGA panel. I have bought a USB 3.0 to VGA adapter and I have installed all necessary drivers to run it. So here is my issue with my display.

In the Resolution Settings it shows 3 displays. 1 Saying Mobile PC Display, 2 saying HP vs17 (My Monitor) and 3 saying Generic Non-PnP Monitor. There is nothing wrong with the monitor as it worked fine on my old windows 7 laptop. There are 2 issues here:
1.) The second monitor is called Generic Non-PnP Monitor and it's default resolution is 800x600 even though it's native resolution is 1024x1024.

2.) The screen is not being displayed even though my computer thinks it is being displayed.

If anyone can help me with my issues it will be much appreciated. I will list some basic specs and If you need any more description details feel free to ask.

OS: Microsoft Windows 7 Home Premium
PROCESSOR: Intel Core 2 CPU T5500 @ 1.66 GHz 1.66 GHz or Intel Centrino Duo

I just received my P50 and workstation dock to replace my W530 + dock.  With my W530, I was able to use my 2 identical extenal displays (DVI-DVI) along side my laptop display for 3 screens total.  All running 1080P.  In the Nvidia control panel it displayed all three screens under the "Set up multiple displays" and I was able to set screen, 1,2,3, etc.  It listed the two external displays and the internal laptop display. With the P50, it only lists my two external monitors and NOT the laptop display under Nvidia Control Panel.  The two external monitors are connected differently due to different port config on the new workstation dock.  Currently they are DVI-DVI and HDMI-HDMI.  Device Manager in Windows 10 lists my two external monitors and one "Wide viewing angle & High density FlexView Display 1920x1080" which is the laptop display.  Under Windows 10 display settings it shows displays 1,2,3 (only two screens shown though) with two screens either being mirrrored or extended. Net, net, I am unable to use all three screen independently as I was on my W530+dock.  Nvidia, only sees the external displays; Windows 10 recognizes 3 displays, but forces 2 to either be extended or mirrored. Anyone esle run across this, and if so how were you able to resolve?  I must have use of all 3 screens.  This is a deal breaker for me if I cannot use all three screens simultaneously and indpendent of one another.  Any...

I have a HP Dock Connector to Ethernet and VGA Adapter (http://store.hp.com/UKStore/Merch/Product.aspx?id=G7U78AA&opt=&sel=ACC)  that I use to connect my laptop to an external monitor (HP ProDisply P221) and the wired network. I now want to connect a second monitor (another ProDisplay P221) to my laptop. What are my options? I don't want to buy a full docking station. I read somewhere that a VGA splitter cable would not be useful as it simply duplicates the same display as one sees on the first monitor. I have an HDMI port available on my laptop. Can I use this port with an HDMI to VGA cable and connect the HDMI-to-VGA output to the second monitor? Will this give me a continuous (and NOT a duplicate display)?Thank you for your help.

I've got an Elitebook 850 G2 connected to the 2013 UltraSlim Dock and I want to drive 3 External monitors (not counting the built in laptop display).  The specs for this laptop says it will drive 3 external monitors using this dock, but I can't make it work.  I've tried every configuration and it seems that the 2 built in displayports on the dock will not operate at the same time.  I can run 1 external monitor conencted to the VGA and 1 to one of the displayport connections, but I get nothing connecting to the other displayport connection.  I'm using identical HP business monitors that have displayport and vga connections.  Anyone have this working?

When i am watching a movie, my laptop screen just sits on the desktop which is fine but I am worried about the screen possibly burning in if i keep watching movies. Is there a way i can put my laptop screen to sleep or on a screen saver without doing the same for the tv screen which is what the movie is playing on???? any help would be appreciated. thanks.

A:Running dual monitors question about laptop screen

You should be able to set your power settings so that only the monitor on your laptop turns off when you close the screen. Just make sure that your hard drives are set to keep spinning and that it doesn't go into sleep mode.

You could set these to be the settings when you are plugged into AC power.

"Power Options" are available under the control panel. You can change your monitor behaviors on the left side.

I have an L380 provided by my employer and thought I'd come up with a good solution for connecting two external monitors whilst working from home. I purchased a USB C to HDMI Cable for one monitor and utilised a HDMI to HDMI cable for another monitor. As theres a USB C video enabled port and a HDMI port on the L380 I saw no reason for this to be unsuccesful. However, it would appear I can only have one display active at any one time. If I turn one monitor off, the other comes on... but I'm unable to run both simultaneously. Is there any reason why this is happening and what are my options for utilising two external monitors at the same time? Many thanks.

Hi, We have the Elitebook 1040 G3 and UltraSlim Dock using Windows 7. I am using 2 HP Compaq LA2205wg monitors that one monitor is connected to VGA and the other Monitor is connected to DVI that is connected to a StarTech display port. Display Adapters: Intel(R) HD Graphics 520.The firmware of the Docking station: 2.30 which is most current firmware. After imaging the laptop and we dock the laptop on UltaSlim Docking station you only get the one monitor which is the monitor that is connected by VGA. The DVI/Display port acts like it is not connected to a monitor or anything. When you go to Control Panel > Display > Change Display setting > you see that the laptop is set to mirror what the 1st Monitor has, then on the second monitor if you look at "Multiple displays" you see that it says "Disconnect the display".  When I change it to  "Extend desktop to this display" Then hit Apply and yes, I get all 2 Monitors working which is good, I can restart/shutdown the laptop and I will get 2 monitors. This is not something we want to do every time I dock my laptop. The next problem that relates to the problem above is when we undock the laptop and it falls asleep for 20 minutes or more we come back to the first problem which is when we dock the laptop to turn it on the lid open or close it still only displays one monitor which is the VGA. We have tried numerous number of things and everything that we have tried doesnt seem to be working so i...

I have a ThinkPad S1 yoga bought in Dec 2013. I have being using the mini hdmi to work of 1 external 1080p monitor these last few years and it has worked fine. I now want to add a new second 1440 x 2560 along side my 1080 x 1920 monitor for a dual monitor set up. (Mostly for spreadsheets, emails, web browsing etc.) I do not mind if one of these duplicates my laptop screen. I was going to get the onelink dock to enable me to do this however I am not sure if it will work. I know the resolution with dual monitors running off the dock is limited at 1200p. What I now want to do is use the mini hdmi on my laptop for one monitor and the onelink dock for the other, however I want to be sure it will work before I go and buy the monitor and dock. Alternatively I could buy an USB 3.0 to hdmi adapted to run the 1080 monitor and a usb hub for the extra usb's I will need. (I think the dock will use less processing power and would be a slicker set up so I imagine it would be better?) You?re  help would be appreciated as I have read there can be issues trying to get higher resolution monitors to work.

Hello All, I wish you luck helping me solve my problem

I am running windows xp home with an AMD 760G chipset in it.

My mother board actually has a port built in for VGA and DVI.

I have 2 monitors that both work great in the VGA port but when I try to put them through the VGA to DVI adapter they don't work. My computer doesn't even recognize the second monitor.

I've tried upgrading my drivers and using different monitors and using different adapters.

I've tried unplugging and replugging everything.

I've tried to enable the second monitor through windows display settings and through Catalyst.

It really feels as if the DVI port just isn't working. I don't know if there is a way to activate the DVI port.

No, I don't have this on warranty.

Any help would be awesome.

Hi there,

I recently bought a second monitor to use with my computer. My display adapters are an HDMI to VGA to a VGA splitter. This splitter has two VGAs coming out into the monitors. Both monitors display fine, but when I identify, they both show up as monitor 1. I want to have one monitor be 1 and the other to be 2, so I can extend my display. If anyone can help me that would be great.

Thank you!

A:Trying to use Dual Monitors but Running into Issue

You're not going to be able to do this with a VGA splitter. The only method to use would be to hook a second monitor up to one of the DVI plugs on your card, then assign either the HDMI/VGA or the DVI as the primary monitor.

Not for nothing, but what kind of monitor(s) are you using? I'd like to believe that you're using something that takes advantage of HDMI (or DVI, for that matter).

I have a DVI cord and also a VGA cord;

Only 1 screen is working; ive tried pressing windows button and P (to extend) no results
I've tried resetting the monitors to 1 = VGA and 1 + DVI - no results
I've tried disabling the driver, updating - no results
I've tried switching it on and off whilst doing this. - no results
I've reset the monitor settings (on both) - no results

I have 1 monitor plugged into the VGA cord to the computer and one monitor has the DVI cord.

I've uploaded the photo of the back of the computer, if i move the DVI cord from im assuming the graphics card slot to the other slot then both monitors are blank.

I have 1 monitor working (its the DVI connection) and as long as i swap that cord to the other monitor it works else i am unable to get them working simultaneously.

The message i get is that there is no signal coming from my computer.

How the hell do i get this thing to work , which use to work, but no longer works

I am running Windows 8.1 with a AMD Radeon HD 7970 GPU.
Drivers are up to date (14.501.1003).
I am using no other software for managing dual monitor configurations.

I have the following two monitors...
Asus VN247 DTV HDMI 1080p @ 60Hz (Primary Monitor)
Connected via HDMI on monitor to DVI on GPU using a HDMI to DVI cable)
Available Connections: Dual HDMI, D-sub.

BenQ FP91G+ DFP DVI 1280x1024p @60Hz (Secondary Monitor)
Connected via DVI on monitor to DVI->HDMI adapter to connect to GPU.
Available Connections: DVI, D-sub.

I'm using Internet Explorer 11 with all settings default.

I use both monitors and switch to using them as an EXTENDED desktop using the Windows key and pressing "P". And then choosing EXTEND.

When I watch any videos on YouTube on the Asus monitor the Asus monitor will go red with thin red lines vertically and horizontally across the monitor. The BenQ monitor remains ok and the rest of the system appears to be unaffected.

I usually have to reboot the system to correct the issue. Usually after a reboot if I go to watch YouTube again it is often unaffected and plays fine.

Can anyone please suggest what might be causing this issue as it is really annoying, thank you in advance.

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?

Did you resolve this issue and, if so, how? I have the same laptop (but running Windows 10) and the same docking station with the same results.

Hey guys. I've recently gotten 2 dual monitors and hooked them up to my Macbook Pro but now things have fps issues especially games. The Fps will just have a seizure and rapidly move inside the range of 10-60 making it impossible to play. As far as I know my macbook should have enough power to handle 2 monitors.

Before the dual monitors Windows 7 ran perfectly on my macbook pro and all my games had steady 60fps. However when I trade to play those same games on Mac my fps would be in the 30s. BUT, now that I have dual monitors my fps and performance on windows 7 has gone to utter crap but those same games that didn't work as well on mac now have perfectly normal fps.... It literally makes no sense.

Is there anyone to fix this?

A:Horrible FPS/Performance issue with dual monitors

Depends on your hardware. Typically in Windows with a dual monitor configuration, gaming only occurs on the primary monitor. In any case, it requires a lot more power to drive twice the resolution (assuming you are gaming on both monitors as a single screen).

I have a dual monitor setup:
- Main screen, where I work using different applications in different virtual desktops.
- Secondary screen, where another application constantly running in the foreground (e.g.: showing a movie, youtube videos etc.), which I need to be always shown.

When I create multiple desktops in my main screen, Windows also creates the same desktops in the secondary screen.

When working, I alt-tab to move between main screen's applications, which potentially changes desktops.
The problem is that the same desktops are changed in my secondary screen; therefore, my application stops showing when changing desktops.

I was wondering if I can resolve this somehow. For example:
1) Disabling virtual desktops for my secondary monitor specifically
2) Copy application to all desktops (therefore, it shows regardless of which desktop I am switching)

A:Task View with Dual Monitors issue

No, you can't do this. A "desktop" is all of your monitors combined. This is why it says "Extend your desktop" when you apply more than one monitors.

Thus, when you have a new virtual desktop, it will display on all monitors, and there is no way to make a monitor see one desktop and a different monitor see a different desktop.

It would be nice if they would add a feature that allows an application to stay on whatever the current desktop is, but I doubt that is going to happen.

I would suggest submitting feedback in the feedback app suggesting this feature. If enough people vote for it, it might happen.

Hi. Have an issue here with a dual monitor setup that is really beginning to irk me. My main display, display 1, is an 'LG 1680 x 1050', display 2 is a 'Samsung 1920 x 1080'..., the problem is, that every once in a while the second displays aspect ratio goes all screwy, like it shifts...for instance, if i have media center on that display, the screen gets cut off so the volume buttons and media center button are off screen.

I can fix it by going into the screen resolution settings and disabling that monitor, and then re-enabling it. But obviously i'd like a more permanent fix.


A:Dual Monitors....aspect ratio issue.

Does media Centre always open on display 2 (the 1920x1080) or do you sometimes open it on the 22" display?

If you bounce back and forth between displays, it may be the 1680x1050 16:10 AR is confusing MC which causes the 'zooming' (for a lack of a better description) when moved to the 1920x1080 16:9 display.

If media centre is only ever opened on the 2nd display and still 'zooms' ... then I'm not quite sure why.

I'm merely hypothesizing as to how this could occur since I haven't personally had this issue occur and therefore don't know of any 'permanent' fixes offhand.

So I have my laptop connected to a second monitor, and whenever I maximize a window on the second monitor, the outer border of it overlaps onto the laptop's screen. I can't explain a possible cause, I'm gonna include some pictures to make it easier to understand.
It's not that big of a problem, just an aesthetic thing...
As you can probably see, there is a small white border on the left edge, which is from a maximized window on the second monitor. Any ideas on how to solve it?

Having just upgraded from XP using the Nvidia dual monitor desktops for years, I was surprised to find Windows 7 has this feature in-built with the added bonus of slideshow desktop images C00L!
So beyond Win7 eye candy which is better, Does it come down to games running faster under the Nvidia dual desktops, what is the general preference here?

A:Is Nvidia dual monitors a poor cousin to Windows 7 dual monitors?..

afaik, there is no real performance difference, as all stuff is handled by the nvidia driver anyway.

And of course the more monitors the higher performance hit as there is more screen surface to work on (the same as increasing resolution).

Btw, the main pityfall of the multiple monitors is that the taskbar is only in the primary monitor, but there are a ton of good third party programs that can handle this, like Actual Multiple Monitors.

Hi all,

I'm having some issues with extending my desktop onto a secondary monitor correctly. I have an HP Elitebook 8460p with a Radeon HD 6470m graphics driver, and the Catalyst Control Center installed. I've hooked a VGA-VGA cable into a Dell monitor. I can successfully clone my desktop onto the second monitor, but I cannot typically *extend* my desktop to use dual monitors.

I've tried extending it using Function-F4 and selecting extend, going to the desktop->Display, selecting the monitor (it is recognized) and clicking "Extend", and going through the Catalyst Control Center to Arrange Monitors, clicking on the external, and clicking "Extend". In all cases, the screen flickers to black, and when it comes back, my monitors are still in "Clone" mode. In fact, even if I've selected to only use the laptop or only use the external monitor, on clicking "extend", it goes back to "clone". I do see that when I select "extend" in the Catalyst Control Center, it *very briefly* shows me both monitors in its configuration area, but then flickers back to a single monitor (the laptop).

I've reinstalled Catalyst Control Center's latest software/drivers to no avail. I have noticed that if I install the latest version of the driver for the graphics card, it resolves the issue, but never permanently. At some other point in time upon disconnecting the external monitor (when I leave work for example... Read more

A:Radeon Graphics Card / Dual Monitors Issue

Someone may have a better answer. But whenever I've seen issues such as this where software won't retain settings, or something works for a short time but continiously breaks in the same way, it's typically a sign of an OS/registry...and a fresh install of the OS will usually resolve the issue.
