OK, I've just spent 4 hours setting up / playing with the 6800. There are a few things that I have not fully set up yet, and my calibration is only partially done.
There are a few "learning curve" issues as well. So far my video material consists of local news in HD, the TBS baseball playoff game with the Angles, and the Spears and Muncil demonstration loop (BluRay)
Here are initial observations:
First, the motorized zoom, focus, and lens shift make the initial setup a breeze. The focus adjustments can be in small steps, which I really like.
Second, the menu is easy to navigate and use with one exception (I'll get to that in a minute).
Third, the unit is very quiet in Normal lamp mode, inaudible in low lamp mode. Projector noise REALLY bugs me, and this is the quietest PJ I've used.
Fourth, the Auto Iris is in a word, terrific! Virtually dead quiet and very fast, THIS is how this feature ought to work!
Fifth, the Mitsubishi sharpness is back!
The picture quality is superb; sharp yet smooth and natural as well. I didn't think this could be done all at once; the 6800 can do it.
Sixth, black levels seem pretty good, the contrast ratio is nice as well, however in my not-so-totally dark room it's hard to tell how good this area of performance really is. Someone else will have to give a more detailed accounting of this. All I am saying is I'm perfectly happy with the 6800's performance in this area.
Seventh, true video blanking is back! I can overscan the screen by two percent, and then blank the areas to still fit within my screen. Since I am not using an overscan feature (and in the process re-scaling pixels), the image stays sharp.
The only learning curve issue is that even if you save all of the video settings, the "Signal" settings (including blanking) are saved per input signal type. After setting up my geometry for the BluRay player, I switched to a 1080i signal from my HD-DVR and the blanking settings were gone! However, once I reset the geometry for this new signal type the settings were saved. Hopefully once all of the different video signal formats have been seen by the 6800, I can put to rest this setup for good.
All in all, this projector is a close to perfection as I've seen! A+
Oh, and one other thing; the panel convergence is as good as I've seen. Virtually perfect across the screen, with some minor blue fringing that is no more than one pixel off. White letters look white!
