hey,

i just installed the zotac gt 730 2gb ddr5 but i'm facing some problems.

- when i play videos on youtube, even at 720p or higher, the videos look pixelated and not at all of hd quality
- some images look grainy
- overall quality loss

exmaple:

i even reinstalled my windows 7 ultimate and reinstalled the graphics card drivers as well but still the problem seems to persist. now, i previously owned the 'palit radeon hd 4850 512MB' and that played hd videos with ease. so is my new card not an 'hd' card and should i got for a card that specifically says 'hd'?

please help!

thanks,
kuber
