The first game I noticed this issue on was Arma 3 Beta. It won't let me set the resolution any higher than 1280x720. I thought maybe it was because it was still in Alpha and beta stages but I noticed the same issue on Metro Last Light and now Dead Space 3. I have a ton of other games that I can set to 1920x1080 so I know it's possible. I have the newest drivers for my GTX 670 (GeForce 320.49 Driver)
I have checked the settings in the NVIDIA Control panel as well and it is set to 1920x1080. I did the dxdiag in Run and it says DirectX 11 is installed so I thought maybe the DX11 was the issue because on Crysis I noticed if I set it to DX10 it lets me set it to 1080 but if I set it to DX11 it limits it to 720. Any help would be greatly appreciated!!
A quick search seems to suggest it's a 720p tv? So it would be reasonable to assume, that being the case, that some games are forcing 1080p (and letting the panel downscale it) and others are going by the native maximum.
Indeed, the TV probably supports 1080i which is usable on some games. Either way, there's little difference between 720p and 1080i so it's not the end of the world.
Well, the panel seems to be a 1366x768 one, i will stick to that one resolution inside the Pc.
If you use 720p you will have: 1280x720 out of the Pc -> Scaled up in the Tv to 1366x768.
If you use 1080i you will have: 1920x1080 out of the Pc -> Scaled down in the Tv to 1366x768 but cutting the refresh at half with posible artifacts (only refresh 1920x540 each time).
If you can use 1080p you will have: 1920x1080 out of the Pc -> Scaled down in the Tv to 1366x768, that would be my second best option depending on the Tv downscale algorythm and the fps you get on a 670 moving the game (at least 60 with Vsync active).
My choosing would be the native 1366x768 if you have it as a valid resolution (after all even with a panel with that resolution you are working with Tv "hardware") with Vsync active at 60Hz.
As juanrdp said above. I have seen some HDTV's that have a native resolution of 1366x768 but still would not let you pick that in a game so for some it may be that the only choose is 720p. To get true 1080p you will need a monitor that supports it or a HDTV that is true 1080p that also accepts 1080p as a input from HDMI. The specs can be confusing on some sets as they will state 1080p but that is a upscale and not the native resolution of the HDTV.
You guys are awesome! Thanks very much for the answers!! I'll be looking to get a new monitor in the very near future :-) I'm thinking that LG 29" ultra wide screen monitor looks pretty nice thanks again!!
