How to connect my PC to TV

CONTINUED 2/2
If I use extended desktop I don't see a thing on my pc monitor and all I do is go blind (back and forth from my room to where the tv is) in order to have the great quality that I want.

Also the hd movie seems a bit dark on tv.

ANy help ??

OK here is something I would like you to answer.

I connect my Ati HD 5770(PC) with an HDMI cable to my TV (all done).

I use the HDMI sound so I have sound as well.

THE DIFFICULT PART: I choose extended desktop and everything appears on my TV and not the pc-monitor.

I use duplicate deksktop and the image appears in both tv andpc monitor but I can't make the resolution higher in order to enjoy an HD quality through my TV.

Good instructions. Thanks.

ok man i have a dvi to vga connector and when i put the tv vga cable, nothing shows up, i want to watch movies on my big tv please help!!

Two things to Check:
1) Have you enabled the second display on the PC - Control Panel > Personalization > display settings. Move a window to the second display.
2) is the TV's Input set to listen to the VGA input port. At the TV use the input selector to cycle through to the VGA or "Computer" port.

3) the VGA cable does not carry audio and will require an additional cable. (shown in the video)

Thanks a lot now we are clear and done, we can watch now from the 32" LCD HDTV. Hope u can post also how to connect 2-monitor from your desktop, using 32" LCD HDTV and the normal 17" LCD monitor. God Bless U man

thanks!

My tv has both of the outputs. It has the white and red and also has something called "audio hmi/pc". It fits a headphone jack, if that helps. Which audio cable should I get?
