SUCCESS! I started in Safe Mode and changed the power settings, initially
with no luck. Tried different combinations with no result. Finally, I checked
the device driver for the monitor and updated the driver for the video card.
This solved the problem and now boots up in Normal mode with full display.
Thanks for your help.
