At my work most people use laptops, in combination with a stand-alone Dell LCD (connected through a VGA cable).
Problem: if you unplug your laptop from the display, the display doesn't go to sleep (it is scanning for a VGA signal), wasting full power.
Question: does there exist (i.e. , commercially available) some sort of adapter that you can plug in between the cable and the display, that would make the LCD think that a computer is connected all the time? (Similar to what a docking station would do, I assume)
