Our TV is a Mitsubishi DLP from around 2006. It is only 720p but is 62". I'm actually pleased with the picture; but the mirror cleaning is a must (what I do not like about big boxy TVs). I found a detailed illustrated guide on the AVS forum that explained how to do it. Takes about an hour.
I couldn’t tell you if Samsung actually makes it or if Mitsubishi does. It’s about 12” deep, whereas our older 720p Samsung was over 18” deep.
I looked at the 80” Mitsubishi very hard until I saw it was still a bulb/color wheel TV. My newer Samsung is far superior in that regard.
