Hi. I just joined, and I'm buying parts at the moment.
I have a 20" Dell 2001FP that i want to use. It's a 1600x1200 and frankly it's the best monitor I've used since my 22" Mitsubishi CRT.
Does Lumenlab have the parts I need to use this monitor? Also, does anyone know about the disasembly issues for this monitor?

Thanks

The path to the 15" projector is well worn, but if you intend to do a 20" panel you will have to be a pioneer. The new optics that Lumenlab sells should accomodate a 20" LCD but you would be the first that I know of to use larger than a 19" panel. I would recommend reading as much as you can in the forums before you decide what size panel you will use. We are in the early stages of using 17" and 19" panels, and the results will be appearing soon.

That's an intimidating thought. Given the expertise in this forum I think I'll try something slightly less ambitious.
Can you tell me, would it be possible to build a box for a 20" monitor, but test it with a 15"?
I guess I'd have to buy the Pro kit either way.
Is there a design for an L shaped box that might acommodate both sizes?

Yes you can build a box to accomodate a 20" panel and use a 15" panel, but there are many things to consider, one or them being throw distance.

You can also build a 15" PJ with the old lenses but the throw distance is not as ideal as with the new optics. With the old optics you would have to place the PJ in front of you or even with you or the screen would just be too large for your seating position.

If you use a panel larger than 15" you will have to use the new lenses and you will be able to place the projector behind you. A 15" panel with the new lenses will have a pretty long throw to get a large screen.

Sorry if this is somewhat unclear, I think that the best place to start is to play with the Lumenlab focal length calculator to see what will work best for your conditions. The thread for that can be found here.

Good Luck with your projector, and again, read, read, read.

hi clamps, don't be too intimidated. i have built both a 15" lcd projector and a 17" one with
the sgi lcd. the process is the same. you can build a 20" case just as easily as one for
a 17".

there are some nice upright projector designs with only one mirror that should work just
fine for the Dell monitor. the lunemlab pro lens kit will cover the dell monitor.

The Dell 2100fp is a very nice monitor, typing on one as we speak. Also it does a nice job
scaling and using the svideo without a computer hooked up to it. If i didn't already have
my sgi's parted out, that would be my first choice as the monitor to use. all the best, tony

Good points Tony, I didn't mean to make it sound too intimidating, I'm just the cautious, planning type of guy. Just thought that it might be a little premature to decide on a 20" right off the bat before weighing your options.

Of course you're right Death. I guess I might be feeling the typical newvie enthusiasm. Plus, as Tony observed the Dell 20" is a great picture.

Oh, and of course there's the mad rush to get something built for the 3rd LOTR dvd due in a couple of weeks. I wish I'd heard about this site a year ago. I've had the cash for ages. boo hoo.

Anyway, I live in Tokyo so finding a good, cheap LCD is a 15 minute train ride for me. BTW, does LL ship to Japan? I want to buy the pro kit as soon as they have stocks.

As far as what Tony said about the Pro Kit, it says up to 19". Are you sure it'll cover the 20.1 inch Dell? I'm not calling you a liar, I just want to be sure before I blow a couple of hundred bucks.

Thanks for your input guys.

Truth is, the new lens is new to me too and although there has been talk that a 21" will work with the new lenses, it hasn't been seen yet. That's the main reason that I have suggested lots of reading. The first thing to find out is your panel dimensions because the fresnels must be as large as the panel at least, plus you will want to have some extra height to the fresnels to allow for keystoning(if you intend to project at an angle). Like I said, it is unproven ground.

If you have a specific size room that you need your PJ to work with, a 20" panel may not be the best option for you. That's why I directed you to the focal length calculator.

I guess the smart thing is to wait till the new lenses get in from China and get all tested.
Menewhile I can build a 15" rig to test the ground.
ok... Patience.

Oh, I forgot to thank you for directing me to that calculator. I'll be sure to figure it all out on paper before I get too comitted.

hi clamps, i hope i'm not a lier No, actually what i did was just measure the
dell 2001fp in front of me and then compared it to the dimensions that Brian listed
for the pro fresnel lenses. it was large enough to cover that active image area of
the lcd. just double check the measurements with Brian before you order.

i would bet you could easily build your enclosure full size for a 20" panel, mount the
15" lcd for testing and swap it out later. all the best, tony" or


deathray, cautious is always good. your rigth clamps need to read up on the process
to see if he is up to all of this fabrication. i was just chiming in that the actual construction
is the same if it is a 15' 17 or 20" lcd. if the dell strips down well with no connector
problems it should work fine. the difference in width between my 17" lcd projector and
my 20 dell in only about 1.75"s so one would need a case just a tad wider.

from what i (barely) remember, i think there was an issue with the pro triplet lens and anything bigger then a 19". but take my statement with a BIG grain of salt (i am) as I really don't remember....

i'd be nice to do all my gaming on the projector at 1600x1200 (like on my current desktop), but unless you (like in your case) you already have the lcd to spare, then 1280x1024 on a huge wall i think will look just as beautiful plus (in my opinion) the lower rez leaves a lot of breathing room for my graphics card (6800gt) to tweak up AA/AF setting for each game without worrying about any slowdowns. Playing HL2 right now at 1600 is really nice, but occasionally an explosion will cause a brief stutter or two, probably woudln't be an issue at 1280x1024... anyway... good luck with whatever you decide.

I've decided (due to the advice of many in this forum and others) that starting at 15" would be a good idea.
I'm going to build one and see how it goes. if that works then i'll step up to the 20".
i'll also document the LCD breakdown to show how others might do it.

so here we go.

Has anyone actually build one with this monitor ? Thanks
