    Scaling Problems using 4K Monitor


    I saw a great deal on a UHD monitor and grabbed it, completely unaware of the issues regarding scaling for programs, particularly older programs, in a 4k environment.
    (For those who also do not know: this is when a program opens and is so tiny on the screen you can't read anything, or it opens in a normal sized window but the text is so tiny you can't read anything.)
    I took the crash course (otherwise known as Numpty School) and corrected a few things.

    • Windows Settings > System > Display > Custom Scaling Settings. I use 190. Seems good.
    But this does not work with some older programs, so...
    I also did the "High DPI Settings" trick:

    • Find the programs .exe file > Properties > Compatibility Tab > Change High DPI Settings >
    • Program DPI > check: Use This Setting…. (Note: “Open Advanced Scaling Settings” just opens the W10 General Settings listed above)
    • In drop down for Use DPI Settings that’s set for my main display when: change to: When I open this Program
    • High DPI Scaling Override > Check: Override High DPI Scaling Behavior > Performed by: Change to: System.
    • OK > Apply > OK
    This works great for some programs but not all. Plus I need to do this for every program with a problem one at a time. Any easier way known?

    But some programs don't use exe. They use dll. And they are freaking out.
    I found this fix below, a registry edit:
    • Registry > HKCU \ Software \ MS \ WindowsNT \ CurrentVersion \ AppCompatFlags \Layers
    • Add Key: C:\Windows\System32\rundll32.exe > Set Value to: HIGHDPIAWARE

    Is this a good fix for this problem?
    Does anyone know of a better, more permanent, or more universal fix?
    Thanks

    :)

    4k Resolution scaling but then watching a 4k video

    Hi,

    I am building a PC with windows 10. I have yet to buy my monitor.

    I'm considering buying a 4k/UHD monitor but given the issues you can have with scaling (i.e. when using program's that aren't set up to cope with the scaling and therefore show up blurred) I am wondering if it is worth it at this point in the 4k/windows
    infancy? Its worth pointing out that I am thinking of buying a monitor no bigger than 24" so not using scaling won't be very good as the task bar will be tiny.

    Also, (my main question) when you use the scaling its effectively at Full HD resolution, correct me if I'm wrong, so what happens when scaling is on and I want to watch a 4k video. Will it be shown in 1080p or 4k? How does it work? What is the scaling actually
    doing.

    Thanks in advance.
     
  3. Dual Monitor Setup issues - 4k and 1080p combination

    The issue is worse than it seems at first. I have a 4k display (200%) scaling and a 1080p display (100% scaling) and even office apps look blurry on the 1080p display. If I unplug the 4k display and reboot the problem goes away. I believe the problem is
    present on all apps and is a system issue. It's been suggested that to get the 100% scaling everything on both monitors is generated at 200% and then the part on the 1080p display is downsampled to 100%, resulting in the poor quality.

    As it is Windows 10 is almost unusable with a very different DPI dual monitor setup.
