Monitor goes black when gaming

Hello: 

My MacBook behaves strangely when trying to play a game (league of legends). The monitor (connected through an akitio node pro and RX580) turns black as if there was no signal. It seems it happens at the most GPU intensive moments (large group fights) and increasing the resolution of the game to the screen native makes it worse just as increasing the game details. Reducing the resolution of the game as well as the FPS makes it better but still happens. This behavior is unique to OS X given that in my windows partition it doesnt happen the game plays at native resolution with high details. It also happens in newly created accounts in my Mac. 

 

I would appreciate if anyone has ay suggestions on the matter. 

 

 

OSX 10.15, 15-inch, 2018, 2.6 GHz 6-Core Intel Core i7, 32 GB 2400 MHz DDR4, Akitio Node Pro, Rx580

Try plugging the monitor cable into a different DP port on the 580. 

Lots of reports of black screens with League and the 580 on Windows.

@mini-i5 Just tried that per your suggestions and still the same behavior. I also just tried it with one of the new 2016 MacBook pros and same issue. When this happens, even the audio going thought he DP goes out.

I have that same problem although usually, my whole computer crashes after! This problem started with egpu disconnecting randomly to begin with but now I sometimes get random computer crashes. Super annoying. I want to say I have noticed something, probably not related but with egpu connected in system information:

Thunderbolt: Port: Status: "no device connected" for both ports,

However in graphics and displays it shows the egpu connected. Maybe because its pcie in the egpu as it shows there but I would have thought it would still register that it was a thunderbolt connection as that is how it talks to my computer.. Perhaps this is why we get the black screen or the random egpu disconnects? The thunderbolt ports go to sleep because it thinks nothing is connected 🤷‍♂️

 

Would be interested what the editors of this think, is there a way I can capture a report of an egpu disconnection error to identify why it is disconnecting?
