I have a Dell studio xps 7100 with an ATI radeon hd 5670 graphics card. I'm trying hook up my vizio m470nv tv to the computer via HDMI. When I do this the computer detects the tv in the screen resolution settings and in the catalyst control panel but no picture is displayed on the tv. I have tried changing resolution settings and refresh rates and still nothing please help!!!!!!!!!!

Most of the modern TV have different display mode. Like my TV, it has several mode, such as "PC, HDMI1, HDMI2" etc

Try looking for the setting to change the mode.
