I'm the wrong person to answer, haven't done this but.....
Out of curiosity I spot metered my 23" Apple LCD display. Thinking 7201
neg (sharpest, finest grain, daylight stock should work well with a D65
iow ~ 6500 degrees CT white balance)
With the "solid dark grey" desktop and the brightness cranked up I get
f 1.4 (24 fps/ standard 172/180 degree shutter) - that's the monitor
set for the 2.2 gamma I use -- with the Mac native gamma of 1.8 I get
1/2 stop more....
(I "should" have a real 18% grey reference somewhere but I don't... )
..I looked at some quicktimes of my work, of course anything dark is
going to fall of _real_ fast...
You could swap the 7201/50D for 7205/250D for more speed, similar
contrast.... but single frame and a longer exposure I'd be inclined to
use the slower finer grained stock.
You've *got* to test first.
PS I would err on the side of overexposure for sure -- Vision 2 can
take it....
Good luck - could look cool, weird, I don't know...
FWIW Harris Savides shot a test with Gus Van Z - for "Last Days" using
DV & then filmed the results of an Apple Cinema Display in 35mm.... he
said it looked "great" but had "too many layers of information"
(paraphrase)
