I connect my PC to my TV using a DVI to HDMI cable. The problem is that if the resolution is higher than 720p, the image on the TV screen starts to deteriorate ( you can clearly see small green dots all over low light places).

The same thing is happening both in Windows and Mac OS X, so that rules out drivers and hardware on the PC side. I also know the Tv is capable of displaying crisp 1080p images, so that only leaves the cable. Are there any bandwidth limitations for such a connection? Or is the cable just faulty? Do you have any experiences with this type of setup?

I'm going for faulty cable. Because I've the same setup. DVI from my GPU to HDMI in my TV. Working perfectly in 1080p.

What is the length of the DVI and HDMI cables? If the cable is very long, you will need to replace it with either a shorter cable, or a cable that is properly sheilded, or add a repeated/signal extender.

Also check for faulty cables, faulty CVI<=>HDMI connector, as well as your graphics card.
