Signal problems with HDMI cable, PS3 and HDTV?

LG5700 HDTV, problems displaying computer using a DVI to HDMI cable? Please read!?

Hi, I have bought a DVI to HDMI cable. I have a LG5700 HDTV / a nVidia GeForce 8600gt xxx graphics card and windows vista. Using a DVI to HDMI cable I have tried to clone the monitor through the nvidia control panel but it doesnt work. Ive read that you have to change the resolution / refresh rate but i am unable to change any of this in the nvidia control panel (doesnt let me) or through windows (changes back to 800x600). I know I cant be goin that wrong as sumtimes my monitor screen flashes up on the HDTV but then goes and carries on flickering. Please, if any1 has a solution they will get themselves best answer and my thanks ^-^
Answer:

FIRST...set your nVidia's REFRESH RATE to 60 FRAMES (or 30 if it has that option) Then START at the 800 x 600 settings and move up to 1920 x 1080 maximum output. And IF you get NO PICTURE with those settings, your DVI OUTPUT might be an ANALOG instead of a DIGITAL signal.... TV sets want digital signals into the HDMI port... Consult your NVidia spec guide to see what the DVI output signal is on it.
