Hi,
Is it your TV full HD or HD Ready. If it is full hd, you dont have a problem buying a DVI to hdmi cable for around 600 bucks, it will work fine. If you have a HD ready, then there is a problem, even with adaptor you will not get what you want, because I have a 7600 Nvidia and tried to hook up that with my panny 32", I ended up seeing some wierd screen, and the VGA mode looked 100X better than this.
Now I updated my MBD which has HDMI output and now hooked up my panny to my Denon and Denon to my MBD, now there is no problem.
Cheers!

Even, I have a good quality DVI to HDMI cable with me, I can give it to you for a throwaway if you want, as it is literally useless for me now.
