Strange TV resolution issue...

post #1 of 32
Thread Starter 
I have a tv that apparently does 1080i. When I set the desktop to 1920x1080i I am limited to a 30hz refresh rate. The screen also flickers because of this low refresh rate I'm assuming. I did a test of a custom res which was the same but I used 59hz, but the screen still flickered and also looked mildly corrupted. So I guess the verdict is that this screen can't do this res above 30hz successfully right? Seeing as it recommends I set the desktop to 1280x720 @ 60hz I'm thinkin that's it.

Well the thing that's odd about it is that I run games on it at 1920x1080 @ 60hz. I do get a bit of ghosting in games (but I think this happens at 1280x720 also and is probably more to do with the response time of the screen right?). The games seem to be fine like this though. Also I wasn't able to select that custom res with 60hz on the desktop (I was only able to test it). It's really forcing it to stay at 30hz. But for some reason games are an exception.

Can anyone help me figure out what's going on here? Thanks.

It's an Orion TV. Is there any specific info you want? Thanks.

1080i TVs aren't natively 1080i. They are 720p.

It's "downscaling" (in actuality just converting, since 1080i is really more like 960x540 per frame) the 1080i signal to 720p.

sorry man i don't quite understand :/ there is definitely more detail in games when i am running it at 1920x1080. i have tested it thoroughly. i think i'm mainly confused about why the desktop can only run 30hz at this res where as games are fine at 60hz. maybe that's what you tried to explain to me but i didn't get it sorry...

Maybe it has something to do with your TV's refresh rate. Some TV's are 50hz and if you put 720p TV into 1080i mode it might sound logical. My TV is also fine, but when it goes into 1080i, screen start's shaking, but I cant see anything like that while playing move or anything.

sounds like the same situation as mine. mine will do 720p @60hz always. it's just when i run 1920x1080i it runs at 30hz and the screen flickers. but somehow games seem to run at 60hz with that res without the screen flickering.

1080i is interlaced. i.e. Half the screen is loaded at a time, that means that on a 60Hz panel the maximum true refresh rate is 30Hz. Your screen can't actually go above 30Hz. If you want to be able to game or anything at 1080 resolution you will need a 1080p screen. It's likely that the issue becomes less apparent during games but it would still be there.

Is your desktop "larger" then the TV too? I can't see like half of icon on ides and around 70% of taskbar. Didn't really play with resolutions or anything yet.
