HDTV Gaming - Resolution and viewing distance

post #1 of 23
Thread Starter 
I am tired of the confusion of people saying gaming is better at superhigh resolution. While more detail will of course be rendered, the benefits of say 1080p are often indiscernable from 720p.

Actually, it only depends on your viewing distance and on your visual acuity. The normal 20/20 human eye can only distinguish larger than about 1/60th of a degree of an arc.

Having a larger resolution is great but you need to be quite close of your monitor.

Have a look at the link for a nice spreadsheet to review your setup. http://www.carltonbale.com/home-theater/home-theater-calculator/

Finally, my 1360x768 setup is great for gaming since I am sitting at 7 feet from the screen. I would not get any benefits to go 1080p unless I move the couch even closer.

The only possible difference I could see would be reduced jaggies because an eye would distinguish pixels if there are flickering because of jaggies/crawling ants. Visual dynamic acuity isn't very well documented though, but I can acknowledge that the eye detects movement better than details in a static image from an empirical standpoint. Indeed, cranking resolution if a brute force type of AA.

Yeah. I guess your close enough.

The thread title is HDTV gaming as in "not monitor".

Do you put some AA?

thats the problem. you are playing on a console it appears.

i game with a my monitor somewhere between 1-2 feet away, and i can without a doubt see a difference between 720 and 1080.

This would probably go over better in the console section.

Eyes are not a digital camera. You can't assign numbers to visual acuity like that. Just because it can only see something clearly that is 1 60th of a degree, doesn't mean that 1 120th of a degree won't register at all. Just because you only notice the jaggies at a given distance and res (and not any other visual glitches telling your brain that what you're seeing isn't real), doesn't mean that a screen with twice the resolution looks intangibly better.

Increasing resolution always has diminishing gains (as do high refresh rates, contrast ratios and everything else), but there is always undoubtedly a gain.

I'll take a 30" monitor at 2560x1600 over an HDTV any day... and this is coming from a guy who actually plays on a 40" Samsung 1080p 120hz LCD tv. It sucks compared to even a 24" monitor.

No. I play with the sig rig. What I say is that 720p from my viewing distance (and I am quite close) is as good as 1080p. What that means is that if you play a bluray on a 37in HDTV, you will not be capable of telling the difference between the two.

I do understand that very high resolution when sitting close has more details. However, I like using my home theater system (big screen, superloud sound with extra bass) and do some couch gaming. The games are pixel-free and the amount of details surpasses what my eyes can see. I need a lot of AA though. At least 8X MSAA or 4X SSAA.

What you say only has merit if the screen you use is small and/or far away. Use a 24" screen less than 2 feet away from your face, and you will definitely notice the difference. 720 and 1080 are terms that should only apply to consoles/tv. I game mostly on PC and have no such restrictions. I'm happy with my 5760 x 1200 resolution.

Yeah. This is what I say and I put a chart where a line is drawn for each resolution to show the treshold between discernable and indiscernable detail. That's exactly my point.

And I am refering to HDTV gaming, hence the 1080p vs 720p. It's all pixels in the end, not worth arguing.

I try to max out AA in all my games. I hate jaggies.
