When checked in the compatibility properties for a shortcut, I assume this means that "Display Scaling" is disabled when there are "High DPI Settings." Fine, but my questions are:
- What exactly is Display Scaling? Perhaps it refers to the setting in the display Custom Sizing Options dialog:
If so, then is it true that a percentage of anything other than 100% is "Display Scaling" (what is to be disabled) and a percentage of 100% mean no display scaling?
- When do I have "High DPI Settings"? My monitor is 2560×1440. Is there somewhere where I choose whether it's set to "High DPI" as opposed to something else (no idea what the opposite of that is)? Is it inherently High DPI? Non-High DPI? I have a Dell UltraSharp U2515H, and, as this is only a 25" screen, perhaps it is always High DPI?
What I actually want is to leave Windows scaled at 150%, so the various UI elements are readable, and make Lightroom and Photoshop work at 2560×1440. However, when I check the "Disable Display Scaling on High DPI Settings" checkbox for those applications, their UI is unchanged.
