Connecting PC to TV

[joshhazel]

Im begging for help at this point!

I am having trouble getting my PC to display on my TV, here is my information:

Video Card: NVidia GeForce 9800 GTX+
http://www.nvidia.com/object/product_geforce_9800_gtx_plus_us.html

Video card out is DVI-I

TV: Mitsubishi 73" WD-73734
http://reviews.cnet.com/projection-tvs/mitsubishi-wd-73734/4507-6484_7-32450674.html?tag=mncolBtm;rnav

These are the supposed resolutions used by the Mitsubishi (per link above):
Supported Computer Resolutions 1280 x 720 , 1920 x 1080 , 640 x 480 (VGA) , 1024 x 768 (XGA) , 800 x 600 (SVGA) , 1280 x 1024 (SXGA)

I was connecting the PC to TV via a DVI-I to Component (RGB) video cable. I tried the resolutions above, plus ALL of the other resolutions that the PC is capable of outputting and 60hz refresh. I have no picture at all (i havent tried fooling with audio yet).

Am I doing something wrong or missing a step? Id be pretty upset if my 73" tv wont playback my pc video!!

Edit:
Im using Windows XP and this is a desktop pc.

If you're using vista (probably similiar for 7 as well), right click on the desktop and select personalize. On the left had side of the window that pops up click connect to projector or other external display. Click connect display and follow the instructions.

I just switched to DVI-I to HDMI converter and now seems to be working... but i also found/made some changes to the nvidia control panel (found some stuff for hdtv output) so not sure which one fixed the prol...
