Computer is an HP Spectre x360 Convertable 2840x2160 (15-df1033dx)
Two monitors are Dell U2414H set at 1920x1080, 60hz
Throughout the day, randomly, all my monitors (both Dells and the builtin HP) will start flashing and whatever I was viewing on the two Dells is now collapsed onto the 4k HP monitor. Usually I can just drag the windows back to where I want them sometimes the Dells are black and the Docking Station needs to be reset. I cannot make it happen, but it appears the more intensive the video the more likely it is going to happen. The “My Radar” app is a good example.
I’m running Windows 10 Home (10.0.18363 Build 18363), 16-GB RAM. Intel UHD Graphics and Nvidia MX250. Displaylink 9.3.3147.0
This is quite anoying when it happens during conference calls.
I’m available for troubleshooting
