TV is only 720p but PC wants to run at 1080p, what's up?

#1GameFauxPosted 3/1/2014 11:51:50 AM
I brought my new gaming PC to the TV where I'd planned on having it hooked up to for a while. It's a 32" TV that is only capable of 720p, but after plugging it in the computer insists on running my display at 1080p. It fits the screen perfectly but something just seems off about the display, like it's a little pixelated or something. I tried setting it to run at 720p but it just blows up my display and shrinks down inside the TV and makes everything look huge. I was under the impression that if I had a 720p TV then I should run at 720p. Anything I should be doing differently?

Because the TV has a processor designed to accept content above its native resolution so that people don't complain when their blu rays won't work on that TV. So it's reporting that it's a 1080p display for compatibility reasons despite actually being 720p.

The reason why 1080p looks "pixelated" is because the TV is downscaling it to fit at 720p. Running at 720p is of course going to make everything look bigger because that's how resolutions work on PC.

Now you said that when you run it at 720p, the image doesn't fully fill the screen. This leads me to believe that the TV has an actual resolution of 1366x768 instead of 1280x720. Check the manual to find out what it's real resolution is and set your PC to that. If it still looks off, disable overscanning in both your graphics card and TV. If it still looks off, make sure your GPU is outputting full RGB so that the TV properly recognizes it as a PC and doesn't scale the image. And if that doesn't work, use the TV's PC input (usually a VGA port) instead of HDMI.

Why exactly would you buy a new gaming pc, but hook it up to something that can only output 1366x768?

Could be his monitor broke or maybe he just wants to game in his living room.

I built it on a budget and couldn't afford to shell out for a nice monitor yet. Figured there was no sense in holding off on the entire thing because of a monitor when I have a perfectly capable TV to play it on. Will never understand why people on this board are so anal about this type of thing.

You should have an option to set it to 720p in the Nvidia control panel and to resize the screen as well. Of course this is with an Nvidia Card. Not sure about ATI cards.

you can get a pretty nice monitor for about 150

Most 720p TV's are actually 1360x768, try setting your resolution to that, and once set, go through the TV's display modes and see if there is a "dot-for-dot" option or something similar. This is what my TV (older Sharp Aquos) uses, and it actually makes the resolution pretty livable.

What do you want from me?

I may be stuck at 1080p, I can't figure out what I'm doing wrong. I set the PC to the right resolution but once I do I can't change the picture to be bigger or smaller. My graphics card doesn't have a VGA port or I'd just use that, so I'm stuck with HDMI for now because it's all I have. I can't figure out what's wrong. I've played around with 20 different settings in the CCC but nothing's done the trick yet.

It's a TV?

Then it has a built-in scaler and is probably telling the computer to just output at whatever.
I know my notreallyatvbutstillaTV has that problem, where it says it can do 1080i but it just scales it down to 1360x768.
