I was looking at a 8" lilliput, but since I cant really find any info on its usability as a screen ive started looking at an 8" Hami instead.

I would order this screen in a heartbeat if I was 100% sure I could use it.

Does the screen use this 20 Pin extension?

I'm planning on mounting it to a 3M 9085 OHP.

Just another resource http://www.b-billion.com/

Yes, there are 20 and 40 pins ffc issue,but 40 pins can place away from the light path.

So i will need both a 20 pin and 40 pin kit to get the electronics out of the light path?

You have to have 20 pins extension,which connecting between two fragile edge of LCD panel, But 40 pins connect between LCD panel and circuit board. I'm not sure what your design box is. My PJ is standard setup.I mounted the circuit board above LCD panel then I can connect ffc 40 pins with out extension cabel.
Hope this helps.

I was just looking it all over again before I ordered and noticed that none of the Hami displays seem to have s-video. This wouldnt be a problem but I want to run my x-box into it along with my various computers. Ive tried running the xbox into my computer and then routing the video to a monitor but the color is off and the picture is blurry.

So what options do I have in the way of up to a 10" screen that has s-video and what sort of FFC extensions would I need for said screen?

This is going on a 3M 9085 OHP.
