i found multiple people who have the same problems with vega, on a windows restart, the displayport cable gets detected with a wrong bandwidth
therefor limiting to either 4k 30hz, or even much lower.
like "2.7Gbpsx1" - limiting to 1650x1280 60hz, even though i'm trying with TWO different displayport 1.2 cable which both worked flawless with my 1080ti
why is there no fix yet?
the first complaints were from november 2017?
how hard can a fix be?
i'll probably just return the card and get my money back. and buy another 1080ti
