RE: P2815Q, U2412M, Surface Pro 3 + Dock. Flickering U2412M
I was able to switch power mode to high performance
when I dock the SP3 using hp power mode -- get a new behavior - the screen just flashes and never displays - that is none of the external monitors come on
when I switch back to power save - they come on but the down stream dp connected still flashes (until I remove the power from the monitor and add it back )
Is there a specific setting in the power plan that you know that I could change under balanced that would drive
Or other suggestions?
