So a small round up of the facts;
- On either the monitor and the TV using the HDMI cable causes colour distortion
- Using the VGA cable though produces normal colour on both. Yet you don't really want to be using VGA when you can be using HDMI.
Now, as HDMI outputs through digital I'm doubting its the cable itself.
So it could possibly be your graphics card that is doing it with the current drivers
You have a few options I'm guessing to deduce the problem;
- You could try rolling back to the previous drivers? In Cod4 for example the new Nvidia drivers caused graphics distortion on my card and the old drivers work better.
- If you have a friend with a laptop, a hdmi port and vista you could try that to see if the tv works perfectly. If so then it's just Windows 7, which means back to the drawing board. haha.
