This does work, but is not "perfect."

The reason you don't get the dreaded roll bar on an LCD screen is 
because the pixels are always "on." Granted there is a florescent light 
source for the LCD. On a CRT, the picture is written on, and then 
blanked, before the next image is written on to the screen. This is done 
alternating lines, first odd lines (1,3,5,7,9,11 - 525) then even 
(2,4,6,8,10-524.) So the image is broken into two fields - running at 
59.94. So since the camera is running at 24, the roll bar is the 
shifting blanking interval.

With an LCD screen, although you don't see the big nasty roll bar, there 
is a small sizzling line that passes through the image.

If you can get a hold of The Arri 35 Book (Jon Fauer) there is a great 
section on shooting off a TV screen.
