Would it be acceptable to send a message through the serial or HDMI port to put it into standby and back on again?

In my experience with plasma screens I usually find that you can play with the Brightness and Contrast controls and get the screen fairly black and it is still OK for viewing your source especially using VGA input.
Lots of places seem to lift all settings for powerpoint presentations so there really bright.
Combining these two ideas, rather than using the serial port to put it into standby, why not use the command to turn the brightness right down, and then turn it back up again when it's needed?
