Dear hertzblaster sir,

can you tell me whether a small LCD with HDMI or DVI available?.

Also can you post the ebay link to AUO 10.1 inch B101EW02 or similar LCDs. My search reveals links only to panels.

The controller is programmed for me by the big controller supplier in China which specializes in big LCD TV controller. They don't entertain small orders.

Dear Hertz sir.
I am a true fan of diy projector idea.and of course yours :--).
what I am getting locally.220/330 fresnel(310mmX310mm),345 triplet,15.6 benqG61hdal lcd,400w bulb.now problem is 310mm wont cover full 15.6 lcd(350mm lenghwise),and if I use 4:3 mode of the lcd to use it with 310mm fresnel,there will be picture distortion.and I live in india,there is a lot of problem with customs,taxes etc if I bring lcd+controller from other places.can you suggest me something by which I can use this lense with this lcd.
another question.of course it is a proven fact from your builds that led will give better picture,but led and led driver is not available locally.do you have led+drivers?
also suggest me that this 15.6 benqG61hdal,regarding FFC issue and stripping,other things(picture quality) I can compromis.
thank you very much sir for your help.

400x320mm are mostly defective. There is a problem in center groove and the outer groove. You get a brown dot at the center bec of 220mm fresnel. And bec of defects in outer grrove, you ll get considerably low brightness at the sides.

I ordered samples from different fresnel suppliers popularly known in this site. .

The 395x395mm is the best quality fresnel for 15-16 inch lcd.
