Computer LCD vs. OHP Panel

[homegrown]

Hey Dudes,

The info on this 100-mile thread is long but impressive. I have been reading as much as I can and slowly building a plan in my head. I already have a 400W MH system and an old dead projector to chop up. The only thing I don’t have yet is the panel and I’m split on what to get – a real projector panel or a 15” PC LCD display. I like the PC display as I already have a PC with a DVD drive, tuner card and digital audio out- but I am unsure how good it will work, compared to the Nview’s that were designed for the job. Is anybody going down this road? So far I have only found one web site:

http://www.csun.edu/~hbpsy028/projector/

If anybody here owns this page pls send an update.
Below is a comparison of the two I have compiled. Is there anything I’m missing here?

OHP Panel:

Advantages:
Relatively cheap
Easy to setup and use
Small foot print -> i.e. less area to light for homemade projectors

Disadvantages:
Low Resolution Max 640 x 480
Lower Contrast
Slower refresh rates

PC TFT 15” monitor, stripped

Advantages:
High resolution (1024x768)
Higher Contrast - up to 350:1
Faster refresh rates

Disadvantages:
Not cheap
Disassembly- very few units can be used
Voiding of warranty
Large screen requires more lumens to light

Thanks,

Homegrown

umm you can get OHP panels that have 1024X768 resolution and higher refresh rates that will work with fast moving videos.

Several people have used Monitors instead of projection panels.
Search for posts by jjasniew. There can be serious difficulties with monitors in moving the electronics away from the LCD.

we do these things because we are do it yourselfers and most of us dont have $4999.00 (in Canada) to spend on lcd projectors. besides, its satisfying to see a good end result and know that you are smarter than the average bear.

Did you read all the old posts.......we discussed this in some detail way back when.

Biggest problem with using an LCD monitor is the size of it.....a 15 inch monitor won't fit on most overhead's.....unless you make a bigger stage.....and most of those lcd's cant have the pcb parts removed for you to lay the panel flat.

If you are looking for a high quality panel and willing to spend the cash....get a sharp QA-2500 ~250 or so and has the inputs, resolution, etc that you would require
