The monitor must either need an external trigger, or sense the video signal.
There's no trigger wire or similar for these monitors, yet some have reported to be able to autoswitch. So, it must look for an increase in voltage for the composite video connector ... which is common to do in home automation, but not always reliable.

Havn't used any of the older ccfl screens, but I can say that after being on for about 30minutes there is zero heat anywhere on the screen or in its direct vicinity. LED's give off so little heat, so I'm sure it was part of their strategy
