View Full Version : What does 720p look like on a decent 1080p TV?

I haven't been exposed to too many 1080p TVs, so I have a question.

I'm building a rig for a friend, on the seriously cheap.

Phenom x3 8600B
HD 3870
2gb DDR2
Win XP

It's gonna be hooked to his 1080p TV, and will mostly play older games, which we will configure for use with 1920x1080 resolution.

BUT, newer games will not be able to run at this resolution. We will need to run @ 720p.

So my question is, does 720p look like a blurry mess on decent 1080p TVs? FOr example, some xbox 360 games don't run at 1080p even if the TV IS, so how do they look when they run @ 720p?

I'm just a little afraid of booting up something like L4D2 @ 720p and having it look much worse than the console version for some reason.

I think ESPN is broadcast in 720p or at least it was....I couldn't tell the difference to be honest.

As long as the TV itself can display 720p good then it should look good... it wont be a blurry mess unless the TV sucks.

most ps3 games use 720p and they look great on my 32' lcd 1080p tv.

Doesn't the quality depend on how it is scaled? I don't know much about this. Don't some TVs have built in scalers, and some video cards also use their own scalers?

I'd like to know more.

720 and 1080 wern't just random numbers pulled from thin air. 720p scales up to 1080p quite nicely and evenly. It won't suffer as much from the uneven pixel matching that you see when dropping your resolution on an lcd a few notches.

Up close it doesnt look so hot.
Every pixel will consist of 4 pixels on the panel.

From a couch some way away, PS3 games look "ok" on my 40", but up close itīs a mess when youīre used to 1080p PC games.
I used to use it as a PC monitor, and the difference up close with 1080p and 720p on games from the PC was pretty big.
Direct pixelmapping vs scaling.
at that size, the pixels are pretty big to begin with, having pixels be made up by 4 pixels in the panel makes it all that much worse.

Video is a very different story though, doesnt really make much difference there.

720 looks fine on my 52" 1080p Mitsubishi DLP.

Yes it will depend on the tv. Most decent ones will make 720 look great. I actually encode in 720 to conserve HD space, because I love the uncompressed DTS HD audio more than 1080 visual over 720.

Video isnīt really comparable with running games though.

Video is just slightly, almost unnoticably less sharp at 720p then 1080p, but not pixelated, crawling with aliasing and jagged.
Turning on whatever processing the TV has to treat the image can often increase latency between when the image is rendered and acctually drawn on screen.

Video will be fine.

Games will look like crap.

I use a 37in 1080p TV as my monitor. For whatever reason movies don't really make that big a difference when it comes to resolution. But in video games things are SO much sharper. I have Oblivion for the 360 (runs at 720p) and for the PC (runs at 1080p). WORLD of difference. Less jaggies. Textures are crisper. etc etc.

Well if it's anything to go by my PS3 running games at 720p isn't that bad on my Sony 46" Z series. Yes it looks lower resolution, but it just looks as if it was a 720p screen instead of 1080p, not like it's not a native resolution and you get a bunch of half blurry pixels or weird extra jaggies.

Maybe it would be worse with PC as a source? I've only used 1080p when gaming on my PC through my TV.
