EliteBook 840 G7 + usb dock g5 black bar in the upper screen on the external monitor

[flaskk]

Hi guys and girls 🙂 

i am working at a company with around 400 g7's with g5 docks. 

case: 

a laptop is conected to the docking g5 and on the docking there are 2 monitors connected (1080p 24" illyama's) 

in some cases we've encounterd that there is black bar in top of the external screen, its solid black and you cant click anything behind it. 

if you reconnect the docking it will solve the problem for period of time, the drivers and bios of the laptops are up to date.

sorry for the stonecoal english 😛

most common cause is a improper resolution or screen frequency setting on the laptop default setting, or screen blanker, or application that opens up on it's own custom screen
