I just got an HP elitebook 840G1. And a 2013 ultraslim docking station. I hooked up two HP monitors LP2465 and LP2475w by the two display port s in the docking station. Monitor 1 works fine but monitor 2 only comes on periodically, maybe after the computer has been out of sleep for 10 minutes, sometimes never. The display is fine.
My old ancient HP dock could handle this just fine before I got the new hardware.
Any advice?
