Discussion and suggestions relating to Display Scaling aka Compatibility Scaling Mode
This is truly a miserably broken and problematic feature of Windows 10, especially for users of software such as Global Protect or other similar software.
It applies to people running dual monitors. It specifically impacts people that run dual monitors that are physically different sizes, or people using a laptop and extended display option onto a physically larger monitor. It can impact people with one physically small monitor (like a netbook display), and a desktop LCD monitor that both have the same native display resolution.
Windows 10 DOES NOT have an option to globally disable this nasty feature.
Instead you basically have two choices:
1) the miserable option of trying to disable it on a per-application basis which some users report being unable to do
2) change the desktop resolution to something that is not a direct pixel for pixel match with your high resolution display for both of your monitors. Resolutions with a width of 1280 seem to work well and globally disable Display Scaling.
Option #2 has the benefit of always working, but has the detriment of making everything seem really big and images or text may not be as sharp and crisp as some users may like.
It WOULD BE IDEAL of the assholes at Microsoft simply allowed Display Scaling to be completely disabled. But like so many things in Windows 10, you, as the end user, NO LONGER HAVE ANY CHOICE. (Which is why I recommend that you never run Windows 10)
Display Scaling on High DPI Devices in Windows 10 causes problems with some software such as virtualization software or remote desktop software
The only way that Microsoft has provided users with to turn this feature off is to disable it by right-clicking on the shortcut of any one of the programs in question, selecting Compatibility and turning display scaling on high DPI devices off, one program at a time. This can be quite a tedious task and there is absolutely no way a person can disable this feature for all programs on a Windows 10 computer, at least not a Microsoft-provided way.
Something to try: Possible Global Workaround using Windows Registry (unverified)
- open regedit
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
- New and click on DWORD (32-bit) value
- call it "PreferExternalManifest"
- set its value to a Decimal value of "1"
