Computer not detecting HDTV

I have a Diamond ATI HD 5670 graphics card installed, and when ever I try to connect my Toshiba LCD HDTV 40E220U to the computer it comes back saying "No Video Signal", I tried what the manual said for the HDTV. But it still wont recognize my HDTV, what should I do?

Hello Razor,

Double check to make sure that in the HDTV on screen settings you are selecting the correct input you connected the PC to. Usually this would be a HDMI or DVI connection.

In addition, in the PC's "Screen Resolution" settings, you may need to select to display to the HDTV.

Hope this helps for now, :)
