I recently purchased a 4K 55-inch Sony X9005b television. So far I had been playing my PS4 on it at 1080p without any issues. Last week I upgraded my PC GPU to the Asus Strix 970 to take advantage of the HDMI 2.0 connection. I didn’t expect to play at 4K on most games so thought that I would more likely play at 1080p or 1440p and let the TV upscale by itself as it does automatically with all content such as the PS4 or standard TV/Blu-rays etc. However, much to my disappointment and lots of hair pulling, I am having huge problems with games at any resolutions when in full screen mode. For example, with ARMA 3, I have my desktop set at 4K resolution and when I enter the game I cannot easily navigate the menus (which I expected and read up on as a consequence of 4K incompatibility). Eventually I manage to put it into Windowed mode by guessing where to click and can change the resolution to 1080p which is what I want to play it at. Then I make it full screen again and it automatically goes to some weird resolution ignoring my 1080p selection (e.g 1650 x 1050 with 16:10 ratio) and doesn’t fill the screen even though I had selected 1080p. I get a really large black box around the edge. Also, and more to the point, the menus still remain not properly clickable making it impossible to at least then select 1080p. The mouse does not align with the options making it impossible to select any option and I cannot click on the resolutions lower down the list once I manage to guess where to click somewhere outside what is supposed to be the clickable area due to misalignment of the mouse cursor. I have no idea why at lower resolutions that the mouse cursor still does not align properly with the menu options and allow me to actually click on the things I point at in the menu. It means that no matter what resolution I select in windowed mode where the mouse cursor alignment works fine and everything is clickable, when I go full screen it all becomes misaligned again and at an ugly resolution. I have tried everything I can think of and nothing solves this. I have tried setting both my desktop and nvidia control panel to 1080p in both the PC and UHD,HD,SD parts of the resolution settings screen but still as soon as I launch ARM3 it reverts to 1650 X 1050 with the mouse cursor menu misalignment problem. I also tried googling this and found the following thread on these forums which gave me some custom resolution settings for the nvidia control panel (I can't link to it as I am newly registered here). I tried the custom settings described there but they still don’t work and the game goes back to 1650 x 1050 with unclickable menus. I have tried X-plane 10 and the same things happens. I got it to work temporarily at 1080p but none of the menu options were clickable once again as though the mouse cursor and the actual settings are misaligned meaning I cannot even select a flight in the startup screen unless I start in 4k. Strangely enough so far Mafia 2 is the only game that worked absolutely fine with both 4k and 1080p resolutions easily selectable in the menu with no mouse cursor menu misalignment issues except when I switched in game from 4k to 1080p I got a big black box around my screen essentially shrinking my screen to display 1080p. Can anyone please advise me where I am going wrong? I am completely lost that my PS4 works fine at 1080p but fairly new PC game menus won’t work properly at standard HD resolutions. I also can’t believe that my 4K tv won’t let me play at 1080p with normal menus especially as Mafia 2 works mostly fine. After spending all this cash, I am understandably a little frustrated that I can’t even play at 1080p in newish games. :bang:***61516; Thanks in advance for any help or suggestions.
