Bought a new tv last weekend and hooked it upto my machine via a dvi-hdmi cable through the specific hdmi/dvi input on the tv. Whilst everything else works perfectly (browsing, general pc usage, wmp/media center etc) I find games keep jerking, as if the hardware is struggling, things run smoothly for a minute or so then things freeze etc and then resume for another few minutes.

This happens across the board with every single game i own, old or new and happens regardless of what settings i use ingame, ie.lower resolution, turn off AA etc. Also not just the graphics stutter but sound also, even when again turning those settings down in game.

Since I use a set of 5.1 speakers for the pc i tried disabling the HD sound output on my gpu with still no difference to anything, i've also tried putting the catalyst control settings back to default and again no joy.

Anyone that can offer some ideas would be greatly appreciated, as said before everything apart from games runs perfectly smoothly using full settings on my gpu and the tv's native 1360x768 resolution, and everything including games used to run perfectly before using my old vga monitor and still does if i reconnect.

Machine specs are:
AMD athlon 64 x2 6000+
4gig ram
HIS ati radeon HD4850 1gig
windows vista premium
samsung 50" plasma via hdmi/dvi

Have you gone back to your old monitor to see if the issue is present there too?

I am not sure how a TV can cause the errors you are seeing. Make sure that if there are drivers available for your display you have them installed as well.

If the issue is not present on the old monitor, but is present on the TV reply and let us know.

He apparently stated his old monitor does still function correctly.

But yes do try newer or the latest drivers. The card could be having a problem converting the signal to hdmi.

Whoops, that'll teach me to post at work while distracted.

If it works with the other monitor without issue then this becomes a very interesting issue. Try running it on the same resolution that works with your old monitor. I know the ratio will be off but see how the performance is and let us know.

I did some research on this issue and it seems that lower resolutions are more CPU bound and until you reach higher resolutions your GPU won't make much difference in your computers setup. It also seemed that 1360 x 768 was not supported in many games.

Try a higher resolution if you can, if not I would return the TV and get a nice large monitor built for gaming.
