Is the pro lens capable of getting a whole 21 inch lcd into focus?

fresnels are too small. plus the triplet wasn't designed for that size either.

Wierd. Then does this forum say "Folded design's for 15" 17" 19" and 21"?

Actually, the pro fresnel lenses will cover a 21" 4:3 panel.

Nice, that means the pro lenses can handle the high rez Dell panels. Prices on them have been dropping like a rock lately.

hmm

So does this mean that I wouldn't be able to use the Pro fresnel with the shorter-throw standard lens? It's kinda important in my design for the ultimate gaming table.

You need the prolens for anything bigger then 15 inches. And the prolens needs the pro fresnels. With the standard triplet, all you need is the standard fresnel.

Which hi res dell panels are to talking about? Can you give me a link to a dealer?

Upon retrospect, i should have been more specific. By "high rez" i meant 1600x1200 and it seems all 20" lcd monitors are capable of it, not just Dell's. All thats left is to check which has ffc issues (or not). An ffc issue isn't all that bad imho as long as you can extend it.

1600x1200 can be easily converted to 16:9 glory with powerstrip and i dare say it'll be a fair step up in quality from 1280x720P

I've now read in a few places that with larger fresnels, a standard triplet can accomodate a 17" lcd panel. This would obviously result in a shorter throw but it would also mean 1280x720P over the inexpensive (and available) standard triplet.

Larger fresnels are available at a few places including 3dlens.com. I'm debating going this route on PJ #2, it would save me a couple hundred dollars over the pro lenses despite the shorter throw distance. I still have plenty of time to decide

Nice! This would mean I could upgrade to 720p for only the cost of the new lcd. I want to do that when the Xbox 360 swings around because 720p is supposedly going to be a standard for it.

You know. With a slightly larger lcd, you could put the triplet a little farther away from the lcd, resulting in a smaller projection, but the lcd being bigger would reverse that effect a bit too. Also being farther away you wouldn't be pushing the triplets capabilities so much. So maybe if you found a fresnel with a slightly longer focal distance ???

Do you know of any fresnels that will work for a 17 inch on the standard triplet or have you not found any yet?

Just looking around on that 3D.com and I found a 395mm square fresnel (about 15.5 inches on each side) with a focal length of 330mm. (about a centimeter farther then the standard lumenlab collector). Do you think that will work?

Not 100% sure but you can do a search here, or peep into diyprojectorcompany.com 's store and see what they recommend I think you "may" have found the right one though i'm not sure what focal length the second fresnel should be. Better research further before plunking down the cash.

Nice that the standard triplet works ey? I also read that placement needs to be fairly exact for the entire picture to fit, but it supposedly fits it 100%. I discovered that information here and at diyaudio about a month or two ago, shouldn't be hard to dig up. I'll pass any linkage as soon as i find it again.

A 17" i've been eye'ing is the the CMV aka Polyview 723D. Though its "only" 450:1, it has 16ms refresh, DVI + VGA, No FFC's as per diyaudio, and cheap . CMV also has a 17" VGA lcd with 600:1 or 700:1 but i can't remember the model #. I wouldn't mind giving it a shot but i don't remember which one it was . I believe it may have been an Amptron or polyview rebrand though.

When I get a 17 inch I'll probably get the SamSung Syncmaster 712N. 600:1 contrast ratio, 1280x1024 resolution, and 12 ms response time. TIGHT!

Brain said in a pm to me once that 17 inches is as big as it gets before the edges start dimming.

I think I'll pm brain and ask him about this. Hope he's not too busy.

Wonder if the setup he was referring to used a reflector(?) Another way of improving dim corners is to run it 16:9 as much as possible

well that will only reduce the parts of the image that are close to the edge. I pm'd brain about it. Lets see what he says.

Brain said we need a 320mm focus distance.

Oh well. Lets keep looking.

Are you saying that 330 mm won't work at all?

Is there any way at all to make a 17" monitor work for a projector?

Yes there is.
Standard triplet with larger fresnels from DIYprojectorcompany.com see Matropolis' PLOG

just wondering where you're going to get 1600x1200 content

Ask minoten. But I agree. At this point a 1080i project is not worth the extra money since you will have to go out of your way to get it. Not like it will kill you but I doubt you can find a 1080i dvd at blockbuster. And most games right now are only 480p. The next gen games seemingly will make 720p the new standard. So I'd say a 17 inch monitor will give you the most out of your money. Rather then spending a fortune for something that will not become standard for another 5 years.

5 years? how about 12 months.. as soon as the whole sony vs rest of the world battle is over re: hd dvd/bluray and studios start hopping on board with either format there'll be a huge boom in terms of software and hardware. players will start around us 1,000 and 12 months down the track will be around us 300.

and minoten what exactly is that avatar? kinda looks like a mountain bike making a jump crossed with a rabbit/kangaroo

hey, i just got my new 2005FPW by dell and really want alot of feedback before i tear it down. i dont seeit on the compatable monitors list but i see some postings of monitors with similar specs., 1680 x 1050 at 60hz 600:1 any help would be greatly appreciated.
