I have a NVIDIA GeForce GTX 1080 Display Driver
Dual Monitors both were on resolution 3840 x 2160 (both recommended)
I needed to update in order to play WoW today (Error driver out of date, fixed when updated driver). After the update, one of my monitors has a max of 1920 x 1080 (Recommended). I can revert the driver, but then I can't play WoW.
I also tried downloading 'GeForce Experience' and getting the latest driver from there (as appose to Windows finding it for me). Still the same issue.
Having 2 monitors with different resolutions is really annoying and I don't want to go back to 1920 x 1080.
Edit: I will also mention the text seems blurry on the smaller resolution Monitor, although it could be my eyes adjusting.
Both monitors are the exact same Samsung monitors.
Edit 2: Issue found Just tried the 1 problem monitor by itself, the issue occurred. Tried switching converter (I'm using Hdmi -> DVI and Hdmi -> display port) and it turns out the issue only occurs with the hdmi -> DVI converter.
I will buy another converter tomorrow and see if it gets solved.
