Just to add I found that on the unscaled screens the text and general
look was a little fuzzy. I assume this is something to do with the
scaling going on. Also if fractional scaling is turned off I cannot set
the 4k screen to 200% on its own as all screens then get set to 200%.
I know its not
Ive just tried this again this morning
1. 2560 x 1440
2. 3840 x 2160
3. 1920 x 1200
I set fractional scaling to 1.50 on screen 2 (Others 100%)
For the session it works perfectly fine, But after logging out and
logging back in the settings do not get saved (Nvidia gtx 1080 with 440
driver)
