I am asking this on behalf of a friend.  He is interested in a color projection
monitor, to project a presentation that is running on a computer. 
Size - presentations of about 25 people.  Actually, he was wondering if
a projection monitor is the best solution. Apparently there are two different
styles, front and rear projection. What are the merits and drawbacks of each?   The screen size would need to be about
6' X 5'.  Any experience with these beasts and/or advice concerning them
would be much appreciated. Performance/price ratio would be helpful as well.

And if I am in the wrong newsgroup, could someone point me in the right
direction.

Please send email to:
elgreco@u.washington.edu

Thanks in advance

Hi,
I have given a multimedia presentation recently and we have used a LCD
projector for this kind of presentation.

If you use a PC, you can use a Genoa Genlock board to get video output
from the PC and have VGA output at the same time still on your VGA
monitor.
We used the new M2200 Pro Genlock, which has a flicker filter and it
worked real good with the Sharp NTSC LCD projector.
The Genlock board was connected to the LCD projector via Y/C output
and the display was very crisp and clear and flicker free !

If you don't need simultaneouly VGA Monitor output, you can use also
our :
24 bit to TV converter box, which fits to your VGA connector. It is an
external box and converts VGA (and true color 640x480) to PAL or NTSC
video or Y/C. It is just 349.-DM incl. VAT in Germany.
If you have a Genoa 7900 24 bit SVGA card you have the cheapest 24 bit
video display !

Best regards, Stefan Hartmann, c/o Ingenieurbuero Gatz & Hartmann.
