I have three 27 inch ACER monitors plus a 49 in 4K screen connected to my RX 590. Over the past few weeks, when I come in and bring the system out of sleep, one of the Acer screens shows the power light...but no display. One time is may be one of the extended and another time it may be my main screen. So far, the only way to get the display back is to reboot the system. I also have had a notification once in awhile of a "link failure detected" message...but not always when this happens. Suggestions?
