    New monitor, UHD, thumbnails do not scale up in windows explorer.


    I bought a new UHD monitor. I expected that some programs might not scale up, but I didn't expect to see that in win10 explorer. At 1280 x 720 resolution, the 'extra large' thumbnails filled the entire window space, nearly touched each other. At 3840 x 2160 and that is not even the highest it goes I can barely see what's in the picture and they don't get any bigger than that! Scaling is set at 300%, but explorer thumbnails apparently didn't get the memo.I put them side by side for comparison. Same spacing only 3 per row but the thumbnails are too small to be useful.Is there any way to get

    :)

    Windows Explorer crashes and thumbnails problem

    Hi, I hope you can help me.
    Windows Explorer is no longer showing thumbnails on files played by Windows Media Player. I've run cmd and regsvr32 shmedia.dll and regsvr32 shimgvw.dll. That seemed to solve the problem...but it created a different one. Now when I try to open a folder on an external hard drive it crashes. I read in an old 2008 post it was an avi file causing the problem and suggested the run cmd regsvr32 /u shmedia.dll. That solved the opening problem but recreated the thumbnail problem. Any help to achieve both functions would be greatly appreciated. Thank you.

    I want to buy a 4k monitor. Is UHD scaling going to be better in Windows 10?

    New monitor, UHD, thumbnails do not scale up in windows explorer.

    Multi monitor DPI scaling issue


    I'm having the exact same problem as pxl8. I have several "HD" monitors an a single UHD monitors. I set scaling to 100% on the HD monitors and 150% on the UHD monitor. The UHD looks fine, but all the "scaling aware" applications look blurry on the HD monitors. Whenever I use an application on those HD monitors that isn't scaling aware, it looks perfect.

    It seems pretty clear to me that Windows is actually scaling those other monitors to 150% then scaling back down to 100%, and the results are very poor. Anyone have any idea how to just disable scaling on a per-monitor basis?
