Hi guys ive been browsing these forums for about a year now and i want to start making a pj (small one) and was wondering if this was a good lcd to start with. I found it on ebay, here are the specs: i noticed it has rca video input.

- TFT Active Matrix Mobile LCD Monitor
- 7'' TFT LCD display panel
- Resolution : 1024 x 768, 60Hz
- Ratio : 16 : 9
- Contract 250:1
- Brightness 380
- Screen Size : 156mm x 94 mm
- Rotary Angle : Picture turn Up / Down and Right / Left
- External Dimensions : 190 (W) mm x 130 (T) mm x 32(H)mm
- USB touch screen function
- NTSC/ PAL auto switching
- VGA Terminal input
- 1 RCA video inputs
- 1 RCA audio input (Left / Right)
- 1 S-Video Video input
- Built-in Speaker
- Operating voltage: 12V DC
- Operating current : 2.2A
- Operating temperature : 0°C ~ 60°C
- Power Consumption : < 8W
- Net Weight : 500g

That's not a very high contrast ratio. If possible, try to find one with a 400:1 contrast ratio (or better). 300:1 is acceptable, 250:1 is marginally OK.

Don't pay more for a monitor that has a higher brightness. You will strip the backlight anyway.

Also, either that monitor isn't widescreen or isn't 1024*768 because that is not a widescreen resolution.

Thanks for your feedback, do you know any decent 7 inch lcd's with component input? i know there is the lilliput one but im not sure if that has component inputs.
Also, i understand the focal length for one of the frensels is 330mm if I cut it down to fit with a 7/8 inch lcd would it reduce the focal length? if not is there a way to reduce it?

I am using a 5" screen from a PSOne screen, lower res than you want at only 320*240, but it is cheap and easy to obtain. Edit: forgot to mention that it has many hacks for vga, component, etc.

Not released yet, but this post is talking about a 7" 1080p (highest HD) panel:
