I have a batch of about 20 new HP820G1 laptops all connected to a docking station with dual monitors. the monitors are connected using the 2 display ports on the docking station.
Every so often I have seen behavior on about 4 or 5 of the laptops where one monitor will flicker randomly with no indication as to why! I have tried other laptops on the same setup with no issues, had the video card in the laptops replaced and upgraded all drivers. yet the behavior still persists on a small batch.
HP says they have not had an documented cases regarding this issue. and I am coming up blank.
has anyone ever seen this behavior before?
