Similar issue .. guidance appreciated
Dell M3800 4K
Dell D3100
Dell P2715Q
D3100 plugged to M3800 via USB3.0 port on left side of 3800 to back connection on D3100.
Drivers loaded before plugging into D3100 per user guide.
Something going on with M3800 display to P2715Q display sync ... P2715Q will not show full display as it appears on M3800 (looks like center portion ... can't see task bar) or icons on RHS or LHS of M3800 on the P2715Q). M3800 display goes unstable when plugged to D3100 ... generally black but will flash with mouse motion.
How to get P2715Q and M3800 to look same and both display? Got both with assumption that they were matched resolution and would be easy to replicate M3800 display on desktop for office use.
Thnx in advance.
