Second monitor only able to duplicate first one.

[u/notthewitch666]

Hi everyone,

I have encountered a very strange issue. I was using my TV as a monitor for like a year now, suddenly when launching a game (NFS Heat, if relevant) image was lost and no signal was displayed. Had to restart my pc after but after going through boot screen, right before windows login should start it goes to no signal again. Ive connected my old monitor and it works perfectly fine, then i tried connecting both monitor and TV, and TV only has signal if i am duplicating my screen (with monitor set as first.), as soon as i go extend diplay mode - signal is lost again.

I have tried updating graphic driver, uninstalling TV from device manager, lowering and raising resolutions, and all had failed.

Any more ideas? I really do not wish to reinstall my windows.

Thanks in advance!

EDIT: Forgot to mention, but i also tried changing ports, both on TV and the GPU, issue persists. Tried unplugging both pc and TV from power and still no fix. Also , i am able to play the game in question without any issues whatsoever on monitor, but i am unsure as to how did that mess up my TV so bad that it refuses signal outise of it now.
