Multi-monitor support is elegantly designed in Windows 8. If you want to see the various features in Windows 8 dual monitor setup, you can read the article in the above link. But from Consumer Preview (CP) time onwards, there seem to be some issues with Windows 8 dual monitor support.
Issue 1 : Second monitor video not playing smoothly when full screen games are played on first monitor. The second monitor lags and delays heavily. You can see a script of this issue in this quote here :
AMD Gigabyte HD6870, When i run full screen games on my main monitor, my secondary monitor will not play video smoothly; Windowed, or fullscreen.
Didn’t happen in win7 64, it’s not an issue of the graphics card keeping up or anything like that. It happens in Netflix and MPC-HC and WMP. With and without FFDShow and other codecs installed.
Happened with the two previous versions of windows 8 also.
There was another user on overclock.net forums, who seems to have the same kind of problem.
i can confirm I have the same exact problem with win8 64bit with my nvidia gtx 670 using the latest nvidia driver….
its a windows 8 problem…
This is basically because of the design safety in Windows 8. In order to save power for battery powered units Windows 8 designers put a cap on the framerate of Windows running in “background” with full screen applications.
Issue 2 : If we run a full screen programme/game on the first monitor, the FPS on the second monitor drops under 10. The problem occurs even if you have latest video card drivers and latest Win 8 chipset driver from your computer brand manufacturer. Some people are getting this issue who are using graphic drivers related to ATI and Nvidia.
Solution : This issue can be solved if you first load the media player or video first and set its priority to above “normal” or higher under Task Manager. Later you can play the game under full screen but in “Window” mode.
If you still want to play the game in full screen, you can try “Compatibility” mode in Windows 7.
Issue 3: Microsoft basic drivers do not have HDMI support and there seems to be an issue if you want to run dual monitor using Intel HD2000/3000.
Solution : You can install the following second generation drivers. The following are the links to Windows 8 Beta drivers.
- x64 Intel HD Second Gen x64_2792.exe
- x86 Intel HD Second Gen x86_2792.exe
Driver version 64_126.96.36.1996_PV on build 7989 worked perfectly for a forum member using 64-bit version. There is also a 32bit version mentioned in the forum.
One of the earlier issues when you try to upgrade from Windows 7 to Windows 8 would be that of dual monitors. In the earlier versions of Windows 8 i.e Consumer Preview and Developer preview, same display is shown on both the monitors. The solution to such problem is to find the right Windows 8 drivers to fix the problem. In case you are having problem installing Windows 8 drivers, the alternative is to install them in Compatibility mode.
You can follow the following steps to remedy such kind of issue.
- You can start off by uninstalling your program incase it’s already installed.
- When you reinstall it, right-click on the install file and then select “Troubleshoot Compatibility”, instead of double-clicking it on the install file.
- Click “Try Recommended Settings”.
- Click “Start the Program”.
This should initiate the Windows 8 drivers installation procedure.
The above are some of the Windows 8 dual monitor issues commonly faced by users. I’m sorry I couldn’t give details of the versions of Windows 8 in which these problems arose, but are more likely to be corrected in the final release version of Windows 8.
When you have more than 1 monitor, extending the display to another is crucial.
In Windows 7 and 10, it has become easy to do this.
You can duplicate the screen or extend it.
Thanks for the useful article.
when I try to type messages on my keyboard the blue “second Screen” tab slides out and deletes the leters & wont behave its self ??? … I’ve tried to click on PC screen only but just keeps poping out ??????????????????????
Windows 7 worked much better with my dual monitor setup than Windows 8. I have one monitor setup in landscape mode and the other beside it in portrait mode, which is great for looking at documents full screen. In windows 7 I could move my mouse from any single point on either monitor directly to any single point on the other monitor in a straight line, even if it meant crossing an area in which there is no screen (on the diagonal). In Windows 8 it is extremely annoying doing this because you cannot cross the null space between uneven monitors so it forces you to navigate the mouse over and then up instead of directly to the place you are aiming for. This throws off everything that is natural about moving your mouse. The difference moving from Widows 7 to Windows 8 is striking. I hate it.
I’m having massive problems with the duel screen since installation. It basically show the same screen on both screens. I’ve tried downloading all the drivers with no joy. I have an amd radeon graphics card. I’m hoping they will release some more updates as it’s a massive issue. I wish i hadn’t upgraded tbh
Did you try installing the drivers in “Compatibility mode” of Windows 7?
