    Task View on Multi-Monitor Setup Issue


    Hi,

    I have three monitors, one 4k and two 1080p ones on either side. When I go into task view, both side monitors go black. It still shows the bar at the top, and any icons of open applications, but does not show the little previews of the other desktops or open applications, nor even the desktop background if nothing is open. I have done a little bit of research and have not found anyone with a similar issue. Any help is greatly appreciated!

    :)

    Blurry text on secondary monitor in multi-resolution, multi-DPI setup


    This is probably the most painful issue I have with Windows 10 right now (and likely previous versions as well, but I didn't have a multi-monitor setup back then).

    The monitors I have are as follows:
    1. 3840x2160 (4K UHD) monitor with preferred DPI: 144 (150%)
    2. 1920x1080 (Full HD) monitor with preferred DPI: 96 (100%)

    Whenever one of these monitors are set as primary, all desktop applications displayed on the secondary monitor (doesn't matter which) has blurry text. Exceptions are the Windows Store Apps like Windows Store and Microsoft Edge, along with the Taskbar/Start Menu, the Taskbar/Start Menu settings screen, the Taskbar context menu, and the desktop context menu which passes the DPI test with flying colours, with crispy text on both monitors (occasionally a DPI switch bug gets in, but I can mostly ignore that). The problem is, as you can probably guess, is that >99% of the applications I use aren't Windows Store Apps.

    Here are some screenshots. The "Taskbar and Start Menu Properties" text is what the text should look like while the Visual Studio 2015 text is an example of the text most desktop apps get. The blurry image is what happens when the UHD monitor is not the primary monitor.
    Attachment 48493Attachment 48494
    Note: Both of these screenshots came from the 150% DPI monitor so it's best viewed at that (144) DPI level. The 96 DPI monitor is similarly affected.

    Things I've already tried:
    • Reinstall the graphics driver (this was unhelpfully given by a Microsoft Support Engineer). Did this multiple times in fact for unrelated reasons.
    • Reinstall Windows 10 (through Reset This PC recovery option). I did this for also unrelated reasons but it definitely doesn't fix this issue.
    • Use the XP Explorer "fix". Merely worsens the problem.
    • Adjusting ClearType options. Alleviates the issue a bit but see next point.
    • Disabling ClearType on the affected monitor. The text obviously sharpens, but it's painful to read and a close inspection of the text reveals the issue isn't solved at all, only mitigated slightly.
    • Replacing the video card. I swapped this in with my older GTX 560 Ti but it's obvious the problem remains. Both it and my current card are NVIDIAs though, so it's vaguely possible the drivers or the cards themselves are the cause. I don't have an ATI/AMD card (that still works, at least) to test the setup and every Intel iGPU I have either has only one monitor output or is incapable of handling UHD resolutions.

    Things I won't try:
    • Setting both monitors' DPI to 96. Text would become microscopic considering the UHD monitor's actual size.
    • Use the text resizing feature instead. I'm going take a wild guess that this is not monitor-specific and would cause everything on the HD monitor to be far too large to the point that I'd rather unplug it.

    Does anyone have a multi-resolution, multi-DPI, multi-monitor setup with or without this issue? The text is painful to read on whichever is the secondary monitor right now, and is extremely apparent whenever the background is dark.

  3. Double Monitor Setup is not connecting

    Hi Yuri,

    To setup dual monitors, I suggest you to press Windows + P keys
    and select Extend or the required option and check for status. If you are still unable to setup dual monitor, suggest you to update the Display Adapter driver by following the steps provided below and check for status.

    • Press Windows key + X and select Device Manager.
    • Expand Display Adapters.
    • Right click on the driver and select Update Driver Software.
    • Follow the on-screen prompts to update the driver.

    Hope this helps. Keep us posted on the status for further assistance.

    Setup dual monitor in Windows 10

    Hi,

    I suggest you to press Windows Key + P on keyboard and follow onscreen instruction to setup dual monitor in Windows 10. As there is a conflict in connecting multiple hardware you may also
    Run the Hardware and Devices Troubleshooter.

    Windows 10 has a built-in troubleshooter to check and fix issues with hardware and devices. I would suggest you to run this troubleshooter to check if the issue is with the Bluetooth adapter. Refer these steps:


    • Press Windows key +X, select
      Control panel.


    • Change the view by option on the top right to
      Large icons.

    • Click on troubleshooting and click on the
      view all option on the left panel.

    • Run the Hardware and devices troubleshooter.

    • Restart your computer and check if the issue is resolved.
    Do let us know the status of the issue. Thank you.
