The High Resolution (HiDPI) switch doesn't seem to make any difference on the Gigabyte Aorus FO32U2P monitor. The text clarity looks exactly the same as before I installed BetterDisplay Pro. There is no major improvement in the sharpness of anything on screen. Is there a compatibility issue with this particular monitor model?

Can you provide some screenshots so the current setting in the Display Mode menu can be seen?

4K displays should have HiDPI enabled by default. A 32" 4K display should look mostly fine somewhere between 2560x1440 HiDPI and 3072x1728 HiDPI, depending on your preferences. However since the pixel density is at around 140 PPI (and thanks to a probably strange subpixel layout of OLED displays) the image may still look somewhat blurry.
