Hello, I have Gtx 1060 6gb for about 5 months and all this time I could set the screen's resolution to 4k (besides my monitor was 1080p) through pc settings on desktop or in games such as PUBG. But the last few days I can't set 4k and the maximum resolution is 1080p both on desktop windows settings and in game options. What did this happen? Why I can't use 4k resolution. I haven't changed anything (neither Monitor nor HDMI). Does it have to do with Win 7 and/or its updates? Please help me solve my problem!!!
