Epson has developed he 1st 4K compatible HTPS TFT Liquid Crystal Panel for 3LCD Projectors. It will probably take a couple of years to make it's way into consumer models. Well, the timing is about right. After several generations of 1080P, what used to be top of the line quality can now almost be reached by the new generation of $1,000 projectors. Maybe this will be the panel used in the new Epson LCD projectors three years from now? I'm hoping it is LED as well. At 4X the resolution of 1080P, it should look pretty amazing.
