2 of 4 Monitors stay black after sleep
i have an macbookPro 16", bigsur and with external razer X + sapphire rx580 8gb with
- two LG 32UK550 Monitors, each connected via HDMI Cable (standard HDMI cable that came with the monitors)
- two LG 27UK850 Monitors, each connected via DP Cable.
In like 40-50% of the time when i wake my Macbook Up from sleep, the two 32" Monitors stay black.
But they are obviously kinda active because, i can go with the "mouse cursor" in the "dead areas". its not that all windows will be distributed over the two 27".
I can get only get them two back to work if i plug the thunderbolt cable from the eGPU and plug it back in.
How can i solve this problem ? Is it a software problem or does a high quality cable maybe helps ?
