i don't know. I've got a dual setup, the 8600 has the same outputs as the 9600. The 2 tuners work drive the 2 monitors/tv's.

There is a NVIDIA beta for windows 7, it installs through windows update. But with me it worked also with vista drivers.

Anyhow since the hdmi direct won't be pixelated it's almost impossible to read the screen. You need a dual setup to be able to watch hdmi using a software player. Or you need to find a way to block the hdmi identifying signal so the card sees a generic monitor.

The definition of your movie will the same, if you use hdmi or vga output. VGA can easily transport the signal density.

There is a wiki somewhere on the subject i believe that's informative

Does the TV have any controls to show the input signal format onscreen? Sounds like the input signal is out of range for the TV to display so it's showing *nothing*. Have you tried connecting *only* the TV and restarting Windows 7? If that doesn't work restart again and press F8 before the Loading Windows... screen. That will bring up a list of boot options including 640x480 video. If that works then we are onto something and can fix it using EDID overriding.

HDMI is sometimes squirely, try unplugging and replugging the HDMI with the TV and computer running. My DVD player will not play sound til I unplug it and replug it, weird but it works.
Did you install the special sound driver for the HDMI? My ATI card included one, I was wondering how they get the sound into the video card, since HDMI has both sound and video.

Thanks for all the help, i will try both the above solutions tommorow. I have not tried using it as the only monitor. When i select HDMI on the TV nothing comes up, nothing to choose or anything like that.
But i shall persevere

HDMI does not transmit to the computer a resolution, since it is a tv. TV's don't have pixelresolutions. This will only work if you connect the tv as a monitor. And for that you'll have to branch it without HDMI cable.

You might try and invest in the dvi hdmi cable option. DVI is not a tv signal and your card might see the tv as generic monitor.

I'm sorry, you're mistaken:

"A DVI signal is electrically compatible with an HDMI video signal; no signal conversion needs to take place when an adapter is used, and consequently no loss in video quality occurs.[94] As such HDMI is backward compatible with Digital Visual Interface digital video (DVI-D or DVI-I, but not DVI-A) as used on modern computer monitors and graphics cards. This means that a DVI-D source can drive an HDMI monitor, or vice versa, by means of a suitable adapter or cable. However, the audio and remote-control features of HDMI will not be available.[94]" -- HDMI - Wikipedia, the free encyclopedia

You just have to arrive at the point that the card won't recognize your tv as tv but as generic monitor
But since the dvi will not relay the hdmi signal you have change your card might pick it up as a generic monitor.

Which is what the wiki said in more words.

Set custom RGB color balance in your video card driver. The RGB map that your monitor is sending from its EDID is wrong -- not uncommon.
