Dual Monitors Solved

    Dual Monitors

    Hi All
    Montitor 1: Dell UltraSharp U2718Q UltraHD 4k
    Montitor 2: Benq BL2711U 4k
    GPU: Gigabyte - GeForce GTX 970 4GB

    Dell: 60Hz
    Benq: 30Hz

    The issue is mainly in Adobe Lightroom. but have had display issues in Bluebeam Revu and Photoshop
    The Map & Web modules do not display correctly, see attached picture (Lightroom-Map Module) as you can see the map should be in the center of the module. See below
    If you drag Lightroom from one monitor to the other I also get display issues?

    If I right click a photo in lightroom and select edit in photoshop I also get display issues in Photoshop (Note: Photoshop is not running when I selected edit in photoshop). See the attached picture (
    Edit in Photoshop) below. If Photoshop is running it is not an issue?

    In Lightroom
    under the performance tab, I am not using the Graphics Processor. If I do enable the GPU I get issues.

    As I mentioned earlier it is not just affecting Adobe products.

    I have asked on Adobe forums, but please note that this was with a different monitor. See the link below, I did not receive a response?


    After a chat with Adobe and changing the resolution on my old set up (the setup in the link above) to the settings below, they come to a conclussion that it was a resolution issue as the modules were displaying correctly.

    Benq BL2711U 3840 x 2160
    : Resolution 1920 x 1200
    Dell U2415 1920 x 1200 : Resolution 1920 x 1200

    The product seem to work? I doubt now that it was a resolution issue as I am now running two 4k monitors. So it is either an Adobe issue or a ​graphics card issue.
    Apologies if this is long winded or I have not explained it correctly.

    Try right clicking your program's .exe file, select properties open the compatibility tab, and set "Override high DPI scaling..." and set it to System Enhanced:

    Have you tried the different compatibility settings?

    Changed it to "system" and everything seems to work OK, that was a quick fix. Thank you.

    What is the "Application" choice and which one would be preferable!

    Application This forces the process to run in per-monitor DPI awareness mode. This setting was previously referred to as “Disable display scaling on high-DPI settings.”
    This setting effectively tells Windows not to bitmap stretch UI from the exe in question when the DPI changes

    System This is Windows’ standard way of handling system-DPI aware processes. Windows will bitmap stretch the UI when the DPI changes

    System (Enhanced) GDI Scaling (see below)

    Maybe this tutorial from @Brink can answer some of your questions, it helped me, as I have a mixed dual monitor set up: Change Compatibility Mode Settings for Apps in Windows 10 Windows 10 Apps Features Tutorials

    Also from Windows Blogs: High-DPI Scaling Improvements for Desktop Applications in the Windows 10 Creators Update - Building Apps for WindowsBuilding Apps for Windows
