Hi!

Sorry for being so late.

I had a similar problem a few weeks ago. I had just started using a HDMI
cable, and there are two HDMI inputs on the monitor. When the screen locker
was activated, the monitor simply switched to the other HDMI input which
defeated the screen lock. The solution was to turn auto-switch input to off.
