anti-reflection
Your images will look a lot better with anti-reflection treatment. In particular, all that white and orange stuff around the lens on the inside will reflect light back through the mirror to the LCD surface,and then back out the lens to fog-up your image. Paint it flat black, or better yet cover it with black felt.

Thanks ..

I finished the screen tonight and fired the projector up ..
Images look fine with the standard Video output from the Lilliput ..
I then plugged in my laptop for a quick test and the Image quality improved a great deal .. The diferrence between the the XGA and regular video out is very obvious..
I will be looking either into an HTPC or a Viewsonic NextVision N6 for DVDs movies etc..

Hey, 101
Nice work, already. You were just looking for a bulb, last week.
Where did you get your condensor, what are the specs, and are you using a reflector? If so, what kind and what are it's specs? Everything looks so close together in the light engine. A nice tight fit.

Hey Steamer..
It was a month ago when I was looking for a bulb but who is counting..
😀
Since then I purchaced the OSRAM from atlantalightbulbs. com
Now on the Light engine..
I bought the condenser from surplusshed.com and it is a 3.75" by 3.75" square, mounted on a metal frame .. so I used it as is..
If I recall corectly has 110 mm FL . I tried to look it up for you but it seems that they dont have it on stock anymore..
The reflector is a (German made..) soup laddle that I bought from a local Marsalls store for about $12.00. It has a nice finish and I polished it additionally to give it a mirror like finish..
.
Since then I saw that Target is carying the Oneida soup laddle for about $9.00 very reflective.. I wish I had spot that before I bought mine..
I hope that helps.. good luck with your PJ..
For the folks using an HTPC and an NVIDIA video card.... here is a great little tool to handle the keystoning issue without messing with the Fresnels...
Especially for those of us that will use the non split fresnel configuration.

It works well but 2 things -
(1) it will slow down the computer - and I got 1.5ghz computers
(2) after you restart the computer you have to start it again
Thanks for the tip Will ..
The PC I used to test it was a 2.8 GHz and I didn't experience any slowness , but I was planning to use 1.6 that I have sitting around ..
Something to think about I quess...

Is there anything stopping you from having the program automatically load at start up? ie. Start/Run/misconfig/NVKeystone/check load @ start up
Just a thought 🙂
the program seams to be C:\WINDOWS\system32\keystone.exe
but it will not run - must be a switch sent to it or something
I tried on another computer, it had the same slow-ness problem
I used task manager to check cpu usage and it does not
show any - I do see the video is slower with NVkeystone
on - both computers are AMD XP cpus at 1.5ghz
one is a GeForce4 MX 440 and the other is a
GeForce2 MX 400 using Video Driver 61.77
there is a free program called Auto Hotkey that you can record
mouse and keyboard clicks - you could record your self
clicking activate in the NVkeystone menu - and load that
every startup - I used that once to set the video mode
on a laptop with a missing screen - so it would work
with a OHP pannel that only used 640X480 60hz
the defalut was 800x600 75hz - I just recored my
mouse clicks to change it, and its replayed at boot
but it will not run - must be a switch sent to it or something

Great recommendations there - Will and HiLLBiLLY .
Now as far as the lilliput RGB, Brightness and Contrast what are the values in the settings any of you guys using ?
I have downloaded a couple test color adjustement images but I would like to know a second.. or third opinion..
Thanks
🙂

After messing with different RGB and brightness contrast settings I found out that the default Lilliput settings provide the best projection images ... just use the Reset option..
Still need more tweaking though

The nvidia properties tab have a color correction pannel
- you can change and import settings -
I had a problem, were I had the LCD panel on
default settings, and the desktop was on default
settings, and then used Power DVD to play DVDs
they looked great and were bright - but my desktop
was dark - and when I watched TV, some TV shows
like the X Files were to dark, but news and
sports were to bright - drove me crazy trying to
balance between the two - I played around with the
nvidia color correction pane,l and never could get it
right - then I tried "import" and "kodak_dc.icm"
and BAM it was bright on every thing - my LCD only
has a contrast like 150-200, maybe not even that -
I have thought that was the problem - but maybe it
just the wrong color setting - but what ever it was it
worked for me on my old Sharp QA-1200
