I will be using a widescreen soon. Its on order from a company in Germany, but unfortunately its thier end-of-line stock. But when it gets here, I can give you the model number and details so you can locate one, if you wish.
Its a Hitachi 7" TFT for experimenting with a new light source. It has good inputs, 2 x video (phono) and 1 x VGA. The response time is nothing too rapid, only 30ms, and contrast is nothing special 200:1. But it has been tested by an experienced, independant DIY projector building crew, in Germany, with good results. Its also remote control, has an excellent OSD, and another nice factor is its capability of handling temps up to 50 degrees Centigrade. With some NVidia graphics cards, you can even control the angle at which the picture is displayed on the LCD. This means super-easy, non-mechanical keystone adjustment, on both axis, (diagonaly)
You will see the results from this panel when I have completed my cool-running, micro projector.
