It is about time to upgrade my InFocus X1( which I have been very pleased with after 2 1/2 years of trouble free service), and I have been thinking about the 7100 for some time. I have been unable to find a local dealer to see the 7100 for myself, so I would like to get some comments from other X1 upgraders, since I am most familiar with it. My current system uses a 100" matte white 4:3 screen, and I sit 17' from it, and almost under the PJ, that I run in high output mode. I would use a 120" High Contrast Matte White 16:9 screen, which gives me the same picture height as the 4:3 but about 2.5' wider, and the pixel size would be 20% smaller. I would also sit directy under the PJ. I mostly watch DVDs as over the air HD has little that interests me, although I do have an HD STB.
My concerns are how the 7100 compares to the X1 for brightness, is the screen door effect more or less noticeable, and the fan noise levels in high brightness mode. Any other comparisons between the two would also interest me. Thanks in advance.
