I got a new PC 9900k/rog strix z390-e and when I try it with my XB321HK blackscreen – no signal input. I try another monitor works fine, I plug the XB321HK in and now it works too. It will continue to work until I pull out the power cable from my PC, after I pull the power cable out I need to plug in another monitor first to get the XB321HK to display again. Anyone got any ideas? Mobo or monitor? It’s the same issue with either the on-board video or 2080ti, make me think it’s the monitor?
