Windows 7: PC To TV via HDMI. No signal.

PC To TV via HDMI. No signal.

Hey,

When I connect my PC to my TV Via HDMI Cable, my TV does not receive a signal. When I check in Control panel>Display>Resolution, My TV hasn't even been detected. My TV is an LG 50", Card is a GTX580, and my OS is Windows 7.

Also, when I connect my laptop to my TV via HDMI (Also on Windows 7), It is instantly recognised and automatically displays, so it has to be an issue with the PC itself.

Spent a while on google trying to find a solution, but unfortunately I couldn't find one. Thanks for any help on this.

Hi there
What do you get on your MAIN PC when you press the windows + P key. It should be settable to display on 2nd screen only.

It should allow you to switch monitors. The monitor probably isn't being recognized since your PC is set to display on your main screen only (by default).

Ensure the TV is switched on and the input set for HDMI. You'll probably have to change the resolution - laptops seem to work fine --desk tops seem to be different -- probably because of the difference in the graphics cards - especially built in ones.

Laptops recognize when a monitor is plugged in -- this isn't always the case with Desktop PC's so try it with the WIN +P key with the TV switched on of course and the HDMI cable plugged in.

If you DO get it to work don't forget to re-set the screen back to PC display before disconnecting or at the next boot if you don't have the TV plugged in you'll end up with a nice blank screen.

Cheers
