Well I just got my Palit Radeon HD 4870 Sonic Dual Edition and I'm upgrading from a 7800GTOC. Here is what I did:

*Uninstalled Nvidia Drivers and turned off PC. Installed 4870 with both power plugs.

*Plugged a DVI-HDMI cable on the second DVI slot. Booted PC, resolution was shit, installed drivers. Rebooted.

*Now my PC had a display and could not display colour black properly, it was displayed was purple, I was like WTF and rebooted, all the same. Windows loading screen showed black no problem. My TV's max resolution is 1360x768, I changed to other resolutions via with Catalist and Vtune, to my surpise SOME displayed colors correctly, but they all looked like shit and stuff was unreadable. I also noticed the HDMI sound capabilities which I never knew of before. Rebooted.

*Plugged DVI-HDMI cable on the first DVI slot. Booted PC and black was properly displayed, HOWEVER, I noticed constant random flickering dots on the screen, Google suggested power problem. Now my PSU is a Antec Trio 650W with 2 PCI-E power cables so powers should not be an issue.
I loaded up Crysis and put it all on high with 4AA, seemed to run fine but I was not blown away by graphics. After playing a little I exited, very oddly enough the flicker dots dissappeared. Rebooted PC. Dots re-apperaed. Did this with both Turbo Mode and Normal Mode.
Also, since I have a UPS I measured My PC drawing out 230W just from my PC while playing Crysis.

*Plugged DVI-VGA cable in the second DVI slot. Booted PC and black was properly displayed, everything seems fine, But picture has this odd surrealistic gloomy effect, Playing with the colors helped a little but not by much. No flickering dots.

So how can I get proper picture quality through HDMI?
