Lets take one projector model as an example. The Panasonic 7000
One way is to bookmark projector reviews and keep a running tally of who said what (important) and when.
Here 6 months after release, the most perceptive owners will figure out the real insidious issues. I wrote this on 5/17/2012
I thought it important to highlight the unusual issues which cause can cause ghosting, at least for the Panasonic 7000 LCD projector. This anomalies are now well documented:
1) dynamic iris
4) ceiling mounting
5) lamp brightness
6) sharpness and clarity settings
7) lamp age
The best is the meticulous German site Cin4Home*
They have already posted an excellent in-depth technical preview of the improvements to the new Panasonic 6000/8000:
3D is a new technology and it took everyone time to come-up-to-speed and determine what is important. In this past year major issues are 3D ghosting and flicker, 1:1 pixel mapping, lamp issues, and overall reliability issues. Notice that no one is reporting the new models allow for owner firmware upgrades, a feature which EVERY other component allows. For shame!
There is much lower on/off contrast measured for combination 2D/3D projectors, especially for DLP. For home theater, Texas Instruments DLP technology is regressing.
The latest deficiency for LCoS, is the ANSI contrast which seems todegrade inversely proportionally to on/off contrast improvements (at least from one manufacture). Our own retired optical engineer says the culprit is not correcting the light scatter from the wire grid polarizer.
I share fault too, as I incorrectly attributed not being able to see the LCoS pixel elements solely to degraded lens quality, but it may be that with bright scenes, the light scatter increases so the pixels can't be seen.
I expect higher review standards this year as we graduate from the School of Hard Knocks.
*Finnish Dvdplaza (pteittinen) and French (Kraine) were really good too, especially with ghosting and contrast. Zombie10K's work merit special mention too
This is my opinion. The other projectors are left as an assignment for those interested.Edited by HiFiFun - 8/31/12 at 3:25pm
