Thanks for the UB (ultra-black) info. UB is much more pricey thought. I just found out this projector, Boxlight CP-310t on ebay (MSRP: 6,999$) for only US $287.03 at current bid... 1.What do you think of this one ?? 2.Should I stay on my first pick, the Epson, or jump on that ridiculous priced offer ? seller midwest-projectors offer some crazy projectors at crazy prices... that confuse me a lot. 3.On the "Highly Rated Home Theater Projectors" page, they sort projectors by some sort of size: -16:9 Widescreen, 1920x1080........................ -15:9 Widescreen, 1280x768......................... -16:9 Widescreen, 1280x720......................... -4:3 Standard, 1400x1050........................... What measurement this mean (1920mmX1080mm) Does this refer to the screen size or projector's resolution ?? if its for screen size, is it in mm? cm? And if they mean pixel, Am I correct saying that the higher the resolution, the better the image ? I ask because I can see some "-4:3 Standard, 1400x1050 Standard" projector at much higher price than 16:9 Widescreen, 1920x1080.... How come ? It's important for me to understand that because the wall on which the screen will be set has a maximum size of 117"x73" (inches) and I want to use it to his fullest. Please light me up Thanks again gwlaw99
