I own 1 laptop HP EliteBook 840 G6 --> conected with a HP G5 docking station (which also has 3 external monitors: 2 displayport connected; 1 monitor HDMI). I know that the laptop supports only 3 monitors at the same time, but I deactivate the laptop's monitor and I'm using only the external monitors. Latley often happens that the HDMI monitor conected to the G5 dockingstation HDMI port is not recognized and in Windows "Display settings" only detects 3 monitors instead of 4(When it works it detects 4 monitors(3 active, 1 inactive).
