External Monitor

HP Recommended
HPL2045w and Zbook 15
Microsoft Windows 10 (64-bit)

All of a sudden, I am having trouble with my extenal monitor, HPL2045w not waking up when I return to my laptop. It seems to wake up quickly and then go back to sleep. Eventually, after maybe five or ten minutes, it turns on. I think this happened after a recent Windows 10 update, but am not sure if it is a mechanical or a software problem. Help!
