Displaying higher than 1080p on a 1080p TV

PregnantNproud · Sep 25, 2013

I know monitors dominate TV's for PC gaming but I want to play games in my living room.

My TV is capable of 1920 x 1200, so my question is would I see any benefit from running a game at a higher resoloution? At all?

My second question is, based on the fact that at 1920 x 1200 my graphics card benchmarks on ARMA 3 at around 65fps, and my TV's true refresh rate is supposed to be 100HZ. (100FPS?) I don't see much advantage to any monitor capable of more than 100fps unless you have some serious dual GPU's running side by side.

Or in other words, am I right in saying my 100hz is quick enough for any game I will play then really, i'd never see more than 100fps as I want max settings on.

(My PC specs are in my sig. I have only just ordered it and this is my first gaming PC)

there's a big difference between 1080 and 1200............. 1080 everything seems "cropped" at the top. 1080p sucks but people keep buying those because of price/avail.

100 hz = 50 FPS. Also there is a higher ms delay on video feed on TVs than monitors, so you might notice some ghosting.

So your '1080P' TV has a resolution of 1920x1200 I have never seen one of those before. You will want to check your TV's manual and see if it actually stays at 100Hz when using it as a monitor, some will turn the refresh rate down. You can get fps higher than 100 but you won't actually see a difference if it's over 100 because that is the maximum refresh rate.

I would check to see that your TV has a gaming mode of some sort otherwise you may get some delayed input from your mouse and it makes the whole experience a drag.

Well, your TV is capable of 1920x1200, which means it can't go higher than that. Your GPU could render an image at 3840x2160 but either the vast majority of the image wouldn't fit on the TV or your GPU would just scale it down to 1920x1200. Basically, if your GPU did render an image at 3840x2160 and then downscale it, you'd be doing the exact same thing that 4x Super-Sampled Anti-Aliasing (SSAA) would do. So if you're already running SSAA at 4x, then you're already running an image at 3840x2160. Of course, most applications nowadays use Multi-Sampled Anti-Aliasing (MSAA). It doesn't look quite as good as SSAA, but it's certainly very close, and it's nowhere near as demanding on your GPU. Other than bragging rights, there's little point to rendering at a higher resolution if you can already use MSAA.

As for your TV's refresh rate, unless the game is really old or superbly well optimized (in other words, a game from 2005 or earlier or if it's running on something like the source engine) then chances are you'll never get even close to 100 fps at 1920x1200 at maximum settings with a single HD 7990. Forget about crossfiring that too 7990; it's impossible due to heat issues. There's an article about that too:

So in other words, yes, 100 Hz is more than enough.

I dont think 1080p is that bad honestly

swifty_morgan · Sep 25, 2013

try a 1080 and then try a 1200. big difference in what you see on the screen.
