"No signal" PC-TV via HDMI

Hi guys, forgive me for my lack of probably basic tech navigation but i have discovered i need to change my resolution to play games through my LG TV and HDMI from my PC - no problems there.

My problem is that i have to be in game to change the settings that i need to alter (or at least thats what i have come to believe from what i have read).

Obviously that becomes a problem when as soon as you load up a game the screen goes blank and then to the "no signal" icon.

Is there anyway i can fix this issue so that i can use my pc? my friend is on hoilday for 2 whole weeks and if i cannot get my PC to work on his TV i am ruined as to what i am going to do while i house sit ha!

Thanks for your help guys.

  1. What game(s) are you trying to play? Can you hook your PC up to a monitor that *does* support that resolution, and then lower it to match the TV or switch to windowed mode? Is your PC a laptop with a built-in display?

    Thanks for the interest and response. I managed to fix the problem by accessing a file in notes and alter the start up resolution from there. turns out his massive 60 inch LG doesnt like 1080 and i had to drop it to 720. who'd of thought?!?
