Multiple monitor doesn't work

[william57m]

Hello everyone,

I cannot make working dual screen since I installed High Sierra.

I have a GTX1060 with the latest driver, my monitor is plugged in DP, but when I turn on my TV (which is plugged in HDMI) the 2 screens become black. And when I turn off the TV my monitor doesn't go back.

If I just turn on the TV and turn off my monitor, it doesn't work neither on the TV.

Also if I turn off my screen and turn on again it stay black and I have to reboot.

Any idea? It worked well on Sierra.

PS: When I click on sleep, I can go back.

Thanks,
William

I changed my system from 18,3 to 18,2 and now I can turn off/turn on my display without problem. But the HDMI still doesn't work.
