I have a new Lenovo P50 workstation, OS - Ubuntu 14.04.
I am trying to connect Samsung SyncMaster 22 inch LED monitor through HDMI port.
Lenovo P50 laptop can recognize the monitor but display on the monitor is sluggish, the graphic seems to be a problem.
Here is the image of the graphic drivers -
The system is currently using Nouveau display driver, I have tried switching to NVIDIA binary driver - version 384. But it didn't produce any difference - the graphics on the external monitor is still sluggish.
Anyone else having the same problem? Should I just remove and reinstall the NVIDIA drivers? any other trick to resolve this?
Update: There seems to be a known issue with ThinkPad P50 and HDMI port. External HDMI video does not function correctly - ThinkPad P50
