I tested my Toshiba m200 tablet PC ( tiny 12 " screen )
In maximum power mode it consumes between 36 and 42 watts ( 42 watts when doing graphic intensive work in my 3D program. )
When on the intenet, I set the power mode to 'normal' or 'low power' mode, which consumes 24/27 watts in normal mode, and 20/22 watts on low power mode.
By itself, the screen comsumes just 8 watts of power.

By comparison, a 20 " iMac consumes 200 watts.
A Power Mac PC ( tower ) can consume over 900 watts even before the monitor is plugged in.

A stand alone 20" LCD monitor typically consumes around 65 -85 W.
If I doubled the area of my laptop screen ( to 24 " ) I would consume just 16 Watts - and this is a very high resolution screen.
How can it be that laptop screens are so much more efficient, yet produce the same results as regular monitors ?
