A little bit chopy playback from PC via HDTV at 1080p

[themachine]

Hey everyone,

so i came to an issue,

I have connected my PC via VGA cable to HDTV (LG, sorry dont know exact model) wich is capable of playing 1080p. And when i play movies on the TV set at 1920x1080 resolution via PC the playback is a little bit chopy, not always but it gets for a second or two every 30 seconds or so.

I am confused what can be the problem, beause when i play video files on my monitor screen (Phillips Brilliance 220SW) at 1680x1050 playback is just fine and smooth. My PC CPU is Qore 2 Quad Q9400 and GPU is Sapphire Radeon HD5750 (1GB Ram, so it should be more then enough to be capable playing High-Resolution video files).

Any ideas?

Sounds like more of a computer hardware/software issue. Double check you have the newest ATI driver for your card. Try a different software playback package, like VLC for video playback. Unless the set has some sort of stutter on other sources, it has to be at the PC level.

Im using latest VLC and latest ATI Drivers.

As i mentioned when i connect my Phillips Brilliance 220SW at 1680x1050 resolution, playback is just fine...

It may be that your TV will accept 1080p only through the HDMI inputs. Check the specifications to see what resolutions it will accept through VGA.

Well, i have checked that, it is supported.

Not sure where to take it, it sounds like it's hardware related. Too much heat on your video card, or another reason system memory is capping
