Why? Because it's 4X the 1080p pixels. Plus there is a real 4K standard. What you have is 4K UHD or just UHD.
As to centering that is either up to the TV or the video card.
But here's the rub. On HDMI your refresh rate drops to 30 Hz and a single 970 can't game at UHD so your best setting for today is 1080.
Pretty simple. I had a 42' LG working with the native res. 1920x1080 all is well via desktop and browsing via FF and IE through HDMI cable connected to my GTX970
Swapped out TV's just had to re-plug in the HDMI to video card / HDMI to cable box and power and the res is 3260x?? looks tiny but thats ok (i'm at work so not in front of TV)
My issue is the desktop looks fine but browsing everything is centered on the screen the left and right side is just filled with blank space. Is there anyway to correct this so all the pages fit? I tried the zoom feature and ctrl. key but it doesn't expand the center just gets bigger. If I knock the res down to 1920x1080 of course it looks fine but any 4k res. it centers it again. IDK if this is just the way it has to be since i'm using the TV as my monitor.
I went in to the Nvidia control panel for scaling / under/over scanning but that didn't work. I think thats mostly for the desktop area I never had to mess with that. I'm thinking maybe reinstall the drivers but thats a long shot.
thx for your input!
PS the aspect ratio is 16:9 also all other modes shrink the desktop and such and I didn't see a Just Scan option
