I've a dual monitor setup with identical 24" 60 Hz WUXGA (1920 x 1200 16:10) LCD monitors.

I'm thinking of switching one of them for a 28" 60Hz non-gaming UHD (3840 x 2160 16:9) Philips 288p6LJEB monitor. I couldn't find it's response time, but as it is has a TN panel and it's (mostly) for work it shouldn't be an issue, I hope.

This is a vanilla LEAP 42.3 desktop work box. If necessary it can be upgraded to 15.0, although I'd rather wait for 15.1. Current configuration is:
- kernel 4.4.155-68-default
- KDE Frameworks 5.32.0
- Qt 5.6.2
- SDDM Display Manager

Video card is a GTX1050 2GB. It supports UHD in both DisplayPort 1.4 and HDMI 2.0b at 60Hz (and higher), so no issues here.

From this post https://forums.opensuse.org/showthre...ff-resolutions it seems that I may not be able to set different scales for each monitor. In both system-settings>display and in nvidia-settings I can set different resolutions, but only system-settings has a scale setting (apparently for both displays as one), and none that I could see in nvidia-settings.

I don't want to reduce the UHD panel resolution, it would defeat the whole purpose of using it.

Note: the UHD panel turns 90°, but I don't think I'll use portrait mode much.

My question is: will I have issues with different icon/decorations/text sizes from one screen to another (perhaps mitigated by the 4" difference between screen diagonals) or is there a per-monitor scale setting?

Thanks,
