Vero4K+, after idle, blank screen and no response (have to reboot via ssh or power cord)

Hi there!

Turning HP lock to OFF has fixed this issue!

What happens now (and why I had originally enabled the HPD Lock feature) is that when I return to the Vero box after the TV is off, the resolution is set to 1920x1080 and I have to go into settings and select 4K as the screen is off-the-edge.
