Not sure what the problem is really. For some reason playing gta4 with the hdmi cable looks a little worse than using the vga cable. Got a 22inch tv with a 1680 x 1050 resolution. I have looked in the xbox display settings but changing it from 1080p to 720p does not make any difference. Wehn using the hdmi cable it looks like there are more jaggeder edges, bit like playing a pc game with no anti-analyzing.
Any ideas??? Is it just the cable or I have not go it on the correct display setting for the xbox.
Cheers
edit: Got the cable from play.com Product name- HDMI Cable for Xbox 360 & PS3
