thats just want i need! but i live in australia and thats on the american ebay

if i can obtain one of theese, do you think it would be worth doing?

i mean because the lcd is so small would it still look good on the wall?

[slize]

even if u will get it, you have to know that no one of this forum tried to tak ethis thing apart yet. no one even tried this thing at all. so there are no informations about the response time contrast etc... all i can say from my experiences is, that those little thingies don't work well... to low resolution, but i am taking this real high to 1280x1024 with an 15" TFT Monitor...

the resolution is 112000 pixels, which means 40000 dots. now imagine your tv has 307000 dots (640x480) lines wich is NTSC; don't know what they have in Australia...) so think about blowing up your tv to an projected picture on the wall with one tenth of resolution and ask yourself if this would be good enough...

in my opinion, you need at least 960x240 pixel, which would be 320x240 dots and which would be 78000 dots

but for a try it is surely worth it, especially for that low cost... so if you try it please let me know your results...

While it is true that higher res at the same screen size will block more light, it should not be signifcantly more than a XGA.

You may get some corner cut on the fresnel not projecting through the tft panel's corners. I get just a touch of that wiht my 15".

Go for the higher res. I do not project more that 75" as I want to keep the "screen door " effect from beng noticeable. A higher res would allow me to project a larger screen while still minimizing the "screen door effect".

As a 15" lcd panel user, I support you, slize. Keep on going!.

finally some positive response

[lincoln]

i am currently the high bidder for the same one on the australian ebay!

but the reserve is not met... i think the reserve might be set at like $ AU 100...

would this still be worth it?

Well, you'll be the one to tell us if it is worth it, once you get it and test it.....


good luck

received my nec TFT today; this thing is awesome: can't wait to take it apart an build my new projector; 15" but 1280x1024 awesome and no shadows at all, the response time must be something like <35ms and the contrast isn't bad at all; it's the same like with my 300:1 panel. but you recognize at once the resolution difference especially when watching football or tennis basketball etc...

this time i'll built a portable "compact" projector sxga projector.
