Pc Game show unsupported signal check your output device
Hello, the "Unsupported signal message" means that the resolution that you have chosen for the game is too high for your screen. For example if you are trying to play in 1420p, but your screen is only compatible with 1080p, then you won't be able to play 1420p.
If you lower the resolution to that of your screen, the problem should go away.
Try holding down the function (Fn) key and tapping the blue monitor key (it's different on all laptops, but usually one of the "F" keys) to send a digital signal to the TV.
