Ok.... I built this PC in April of 2016, and it has been running the same installation (can't believe it) of Windows 10 ever since, flawlessly. At the same time I built the PC I purchased a 4k 55" TV as my main display. The TV I have is from late 2015 (2016 model I believe) and is called the X810C (55" version - it's a VA panel and it's 4K). My initial gpu was a 980ti. When I first fired up my system, I was alarmed at the fact that windows (and nvidia control panel) saw my display as native 1080p (I don't understand why this is). I quickly figured out I could set a custom resolution in nvidia's control panel and that did the trick, and this system (and most of the time, this tv) have been running 24/7 for maybe 355days a year ever since (8yrs in april). I've since replaced my gpu twice, going from the 980 Ti to a 1080, and then to a 1080 Ti which I used until about an hour ago...
Fast forward to today. I purchased a 7800 XT over the holidays and decided to install it today. I took all the precautions, ran DDU in safe mode, etc. Even turned off Afterburner, which I've used this entire time as well. But I figured I'm going to give the full-on Adrenaline software a shot first. Well, first thing I notice is I'm back to 1080p. I honestly forgot this was going to be an issue at all, since I never had to touch that nvidia control panel setting once since the initial setup on day1. It IS a 4k display (again, Sony X810C - look it up on RTINGS, etc.), and it has ZERO issue displaying windows and playing ALL games in 4k (I game almost exclusively in 4k/60/vsync since I don't play huge AAA blockbusters and 4k wasn't much of an issue with the 1080 Ti until very recently). To my absolute HORROR, though, the AMD software is telling me I CANNOT set this display's resolution to 3840x2160p because "it doesn't support it". That's b******. It is a 4k tv that for some odd reason shows up as 1080p native in windows. It works beautifully as a 4k monitor for me and many others I've spoken with who use the same TV. I repeat, this is a 4k display. Therefore I believe there MUST be some way to successfully force the resolution without NEEDING to use an Nvidia card.........
I realize I typed out a whole story... but I'm freaking out here. I have already opened and installed this near-$600 card. I REALLY REALLY don't want to go back to my 1080 Ti because of this (which should be easily solvable - I just don't know how). So, PLEASE, someone help. There has to be someone from AMD or with enough knowledge/xp working with the hardware/software who knows how to solve this problem. Right now my life is basically on hold from this moment until I can find a solution to this. I really really need your help; it will be GREATLY appreciated!
