The only high thing is the 4000 lumens, all the other specs are less then normal for a home theatre projector, this projector is more directed to rooms with light in them as i suspect like presentations etc. of course it can work for home theatre, but doesnt seem incredible at all. It has a 1.5x manual zoom compared to 2.1x automatic zoom for projectors in its price range, it has 3000 contrast compared to 100000 to projectors in its price range , it has no vertical and horizontal lens shift, only vertical keystone, it has a considerably loud fan compared to home theatre projectors in its price range, so basically they have taken all these other specs and compromised them for the 4000 lumens. the price is normal, nothing that incedible. IF it was 3D ready then that would be something since it is 1080p native. They have the pro8450 which is 3D but 720p, and it has reached 1500+ price, that would be more attractive to me. just my personal thoughts.

It is a presentation projector first and a home theater projector second. I do not see how they can get 4000 lumens out of a 280 watt bulb. If it had a 330 watt bulb I could understand. Are the newer dlp chips more efficient? Most one chip presentation projectors and many bight 3 chip dlp projectors only have a 2000 to 1 contrast ratio.

I think it's a presentation PJ at best .. the specs posted make it a poor contender for true HT use, IMO .. true HT does not need 4000 lumens, and certainly the black levels would be less than satisfying .. I suppose a well lit room might benefit, but that's not true home theater

For rear projection home theater it has great specs. You need high lumen output to watch a 133" diagonal rear projection screen with the lights on. For that purpose contrast ratios over 1000 to 1 do not make a difference.

I've been in this hobby for 40 years .. if those specs work for you, enjoy it .. I personally would not enjoy it as I like a lifelike picture ..


Did not notice you posting your application as rear projection .. you must have plenty of space ..

Hello.


I tried to look up for any information relating to the Viewsonic Pro8400, but let's assume it's like a high brightness Pro8200 (2000 lumens rated) and the calibrated mode brightness of that projector is between 1300-1500 lumens (let's not worry too much about contrast). Granted I am aware that it is made for business and conference rooms, but let's say I want a 22-23 foot wide screen (or 25 foot diagonal; for 16:9) and with an anamorphic lens (DIY), I get a 29 foot wide screen (or nearly 32 foot diagonal; for 2.35:1). Let's also assume that the D6500 calibrated video will clock at about 3000 real lumens at mid or telephoto zoom, and that the color wheel is comparable to the pro8200 (I bet it's a 2 speed, but nohing wrong wishing).


So what I'm saying is that other than it's quibbles, could this have the potential of being useful in a large, light controlled theater of this large a screen size? I maybe just dreaming about a $1700 1080p projector with a 30 foot scope screen. Heck I need a room and screen material to achieve that (maybe paint).
