Question Whenever there are 2 monitors connected there is no signal going to any of them.

[SargJack]

Rx570 graphic card (newest drivers 19.4.3) - I can run only 1 display at time whenever i try to connect second one they are both not working (i see black screen on both, when restarting i can see the screen to enter BIOS but if i enter it or wait for pc to boot both displays go black again) but if i'll connect one at time it works. Both monitors are connected to hdmi port. System is Windows 10.

Are you using some kind of an adapter?

Than how are you replying to the fourm? Than remove one.

And please, the OP want's to use two screens instead of just 1, telling him to remove one is not a solution to his problem nor a good way to replay, and he is replaying to this forum while using one monitor not both of them.
Please if you going to replay to someone have a solution not tell them to remove something with no solution.
