That could be true about the fans bothering some people with the pro8200. My head is less then 1 foot from the pro8200, when I'm seated, I have the pro8200 on a bookshelf 4 or 5 foot above the ground. I also am using eco mode, lowest mode, and I never hear the fans, now I'm not really listening for them, but really I never noticed it. Now when I turn the unit off, yes, that is when I hear the fans go for about 20-30 seconds before shut off. I'm so close to unit, it's directly above my head and back less than a foot. I usually have room fan on or computer on, or air conditioner could be on, so there is always a little noise in my room. So in super quiet room maybe I would hear it, I also have speakers directly to the side of me, so movie or game or something is blaring out the speakers, when I'm watching stuff, or the computer is directly behind me, below the pro8200. So thinking about it, I might be the best test subject for the fan sound test.
Yeah, maybe with special screen the hc4000 would work for you, hc4000 (1300lumens) vs pro8200(2,000) lumens.
Also, I am in room that is not batcave, the windows on the side of room are covered with blanket when I watch the pj during the day, but behind the screen 2 windows are still shining a little light into the room.
Now if you are in darker room, the mits hc4000 would give you better blacks and over all better picture, but you might be pushing it if not in batcave, 700 lumens less does make it a very low lumen PJ.
optoma hd20 ... ..1,700 lumens,
benq w1200 ...... 1,800 lumens
pro8200 ........... .2,000 lumens ,
hc4000 ............. 1,300 lumens.
Coderguy's reference point is in dark room, with dark walls, dark carpeting, dark chairs, with special screen. So for him, the hc4000 looks awesome compared to the other models, it's dark in that room so having too many lumens would be like someone shining a flashlight in your face, you get the idea
. I'm not watching my PJ in that type room , because it sounds like a wonderful room for watching movies and gaming. I would love to have a room like that. . It would be like going to movie theater , only better, no loud kids or people with big heads in front the screen. But out of the models you listed, the mits 4000 falls far shorter than any other models you listed in the lumens dept.
