Mitsubishi 82 inch big screen TV or projector?

I saw that beast in sound and vision.

Cannot fathom why the hell anyone would want a TV that big.

For the same price, you can hang a plasma for casual viewing on the wall, put a retractable screen in front of it, and a nice high quality projector in the room for serious watching.

Save yerself, yer friends, the delivery guys the hernia and backpain.

that TV takes up a serious chunk of living room real estate.

If you also want bragging rights, then the TV is definatly the way to go.

I diddnt read the review cause the thing is way to rediculous for me to ever consider, but make damn sure this thing is gonna be compatible with HDTV once everything between the FCC, DTV makers, and broadcasters is worked out, or else yer gonna have one hell of a boat anchor.

I will not go into great deail on your projector question. I will let the pro's answer that. Although, I (me) would go with a low hour used projector. Possibly even stack 2. The 82" Mits doesn't stand a chance against a good line doubled projector.
My biggest concern is your room dimensions. Dude, Those are horrible dimensions you are talking about here, For the sound portion. Let alone only a 120" screen in a 22' wide room. You will need to break out the hammer and nails man and divide that room up correctly.
The proper dimensions are to be based on your ceiling height. Someone help me out here, it has been a while since I had to do the formula. Lets see, 20' high ceiling. Whew, I think it is X 1.3 for width, X 2.3 for lentgh. Is that right? You have some real problems here.
That is unless you just don't care what it sounds or looks like and just want to impress people. I suggest you find the proper formula and spend the money correctly. Measure once and cut it twice as the old saying goes. Maybe you could divide the room and have a nice entrance with the popcorn machine and that stuff. I wouls go 2 projectors stacked and at least a 18' wide screen. Maybe 4 rows of some cinema chairs. Hope you have a real good system to fill that room.
All in all though I wish I had ceilings that high when I built mine. Maybe you could put a basketball court in.

If you plan on sitting more than 9' from the set or want multiple rows of seating you'll want a screen bigger than 82" diagonal. Probably much bigger.

Beyond 13' even a 120" diagonal 16:9 screen is going to start getting small. I'd consider it too small for home theater use beyond 17' and marginal well before that.

Attempting to get 120" diagonal at both 4:3 (96x72") and 16:9 (105x59") will be difficult and either produce a 4:3 image that's too big or wide screen images that are too small. A 59" high screen screen is a better idea (4:3 will be 79x59 for 98" diagonal) assuming 105" is the appropriate width for you (people's sensitivity to source/projection artifacts varies), your projector (which determines the sorts of projection artifacts you'll have), and your seating distance.

You really need to start playing with projectors and seeing what subtended fields of vision work for you.
