Trying to connect tv on pc via hdmi. No signal

[cyabadas]

Hey guys, this is actually my first post.
I have been having problems with connecting my pc up to my tv. My tv detects that something is running off the hdmi because it becomes able to select, but once I go <Input<HDMI1 my tv says connecting in the top left hand corner for about two seconds, then says "No signal". My pc isn't detecting the tv at all. I'm about to throw in the towel.

Did you go into display setting, and tell the PC what you want?

Hey buddy, just seeing if you got this issue handled yet, but need to know what operating system you are running. In windows 7 goto control panel goto display, select connect to projector. But really need to know what OS you are using
