    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

    The above registry edit seems to work. No problems to report as of now.
