We bought one of these HP quick release devices for our Vesa compliant TFT. 
It's Vesa standard mount and allows the television to be unclipped from the 
mounting arm in seconds, which is a lot better than having to unscrew the 
screen for travel purposes.

Works great - sold in a few places, but very quick delivery from HP 
themselves.
