#2276 Blurry UI on secondary monitor

[Thany]

The UI is blurry on my secondary screen.

My setup:
Monitor 1 (primary): 27" 4K set to 200% zoom
Monitor 2 (secondary): 19" SXGA set to 100% zoom
Windows 10 20H2

The UI is fine on the primary monitor. The UI would also be fine when using only the secondary monitor, having disconnected the primary.

It seems the UI is rendered at the zoom level of the primary monitor, but when displayed on another monitor it is somehow scaled down pixel-by-pixel or something, instead of rendering at the zoom level of that monitor.

Most other programs render perfectly crisp on my secondary monitor.

I have not yet tried any compatibility settings, because they should be neccesary only for old software.

Please note, in order to test 4K zoom level, you do not need a 4K monitor. You can just set any monitor to a higher zoom, even 150% should show the issue. And then leave your secondary monitor at 100%.
