Dr A Can you please post pics of your "perfect" uniformity and "decent" convergence? And Parksar your red and green all over? Parksar how many hours on yours?

I want to compare...

thanks!

I did not try the maximum position because it will dim the picture more and 24 feet away will be less practical.

I'm trying to find the best setting on my receiver to delay the audio enough to sync up with the delayed video in FC M2. Right now I have it set to about a 100msec delay, but I'm still not completely satisfied. It is difficult to adjust since my receiver does not let me adjust the audio delay while watching the video. If only my receiver had an "autosync" function with a microphone and photodiode to measure the delay!

I know this is not the same as actually moving the PJ, but candidly, I am not inclined to move my mount and rewire everything to accomodate a PJ when I am already operating well within its design limits. Plus, moving the PJ several feet in front of the back seats would bug me.

My old ax100 was much, much sharper, which shouldn't be the case, and compared to the 1080UB its not even close - the 1080 UB is razor sharp.

Zooming it back out to screen width size (approx 106") just shows how bad it is - red and green are just way off, and they are off all over the screen, not just in the corners or top, etc.

Guess I'll call PP Monday am.

Anybody else have one in the DC area yet? Would love to see what a good one looks like.

Rock Band 2 has a feature that lets you calibrate audio and video lag by using the RB2 guitar. The guitar has a microphone and photodiode built into it. I connected HDMI directly from my Xbox360 to the AE3000U, and here is what I got:

Normal Frame Response, no Frame Creation - 30ms
Normal Frame Response, Frame Creation Mode 1 - 81ms
Normal Frame Response, Frame Creation Mode 2 - 130ms
Fast Frame Response, Frame Creation Mode 2 - 130ms

I'm not sure which reviewer found that FFR turned off frame creation when enabled, but that is obviously not the case.
Also, I ended up with the same measurement between normal frame response and fast frame response (with frame creation off). This is a bit confusing... Maybe fast frame response doesn't work with digital sources? I ran the test multiple times and came up with 30 or 31ms every time.

I hope I'm wrong though. I haven't tested this too many times as I don't want to keep turning the projector off and on.

I just finished watching 60 minutes in HD and the entire show I was blown way by the image quality. Same goes for the NFL broadcasts Pre and Post game. So far Normal Mode seems to be the only one I like for all viewing.

I'm not going to use the lens cap anymore and will just clean it when necessary. Aquafire, could something similar be happening to you?

I'm always amazed at how different members settings can vary. Brightness down!!! HMMMMM let me try it

Yeah, with the brightness down it gives it that plasma inky black look...I love it!...Watching the Colts /Pats game on Directv in HD...Looks incredible!...Try some HD local channels too.

I was finally able to order the 3K today. I should get it on Thursday (ground shipping).

I've been waiting for a certain online dealer to get the Panny in stock, due to their 30 day, 100% refund, no hour limit, free shipping and no tax policy. Their price is the same as all of the dealers on this forum. Sadly, I can't post their link here for other members, due to forum rules.

OT:
While I hate not being able to post the link for others, I would have a different take on it if I was a forum sponsor.
e.g., say that I, as a dealer and forum sponsor, took out a small business loan at the bank and ordered a shipment of JVC RS20s. The shipment is due on Thursday. I log on to AVS to check on my customer base, with images of that new boat that I'll buy with the profits, in my head.

WTF!!! Some A*****e (Elkhunter???) posted a link to a non AVS sponsor, who will have RS20s in stock on Monday.

Within minutes, HORDES of AVS "D65ers" order from this so called dealer, depleting my customer base by 90% within hours.

On Thursday, my RS20 shipment arrives; leving me with interest to pay on the loan and long-term warehouse costs before I can move them. And no new boat.

I'd be SUPER p.o.'d......and rightly so.

I plugged mine in tonight and I think I got a good one as far as convergence. With the center focused the corners are less in focus, with the upper left seaming like the most, but I don't think it is too bad in this regard (especially considering the price point).

I have the projector just overhead and behind at about 16' from a 10' wide High Power screen.

One minor quibble is that the remote doesn't work when I try to bounce it off the screen. Seems like I need to aim it at the projector to get it to work and even just shooting it behind me without taking care to make sure it was pointed close enough to the projector didn't always work. I tried the remote from my AE1000 and that works much better for me, so I've been using it.

I was wondering how well the dynamic iris would work with the Dynamic mode where it has been reported to give a dynamic CR that was about 10x the native CR. I tried the projector like this with some different material and didn't notice bad side effects from such a big multiplier, but also wondered if it was really giving that much. What I discovered with some measurements with basically factory defaults other than that I put it in Dynamic mode (bulb was on high or what they call Normal, Contrast and Brightness were at zero) was that there is an on/off CR range it will do if you only include right about when a full black image goes up and what it will do if you give it some time. At a little distance from the projector I measured white at about 11,000 lux. When I then put up a full black image and tried to measure what it was giving in the first second or so I got 1.67 lux. Then I counted in my head and estimated it took 10-15 seconds for the iris to slowly close down to settle at .24 lux. So, about 6600:1 on/off CR right away and about 46k:1 after some time.

I'm not reviewing projectors anymore, but if I was I think I might do something like report the on/off CR a projector with a DI can do within maybe 2 seconds and what they can do if given a lot of time with a blackout screen.

I should mention that since the projector was showing steps above reference white (video 235) out of the box, I'm sure I could have raised the Contrast settings and gotten somewhat higher numbers than above by crushing some of the stuff above video 235. I didn't measure any colors or adjust them in the menus though.

As far as ANSI CR, in Dynamic mode I measured 330:1 and for a modified ANSI CR of just measuring the center 4 rectangles (I think this is what Greg Rogers does) I measured about 250:1.

I've done some experimenting with the frame creation. I was checking out the fairly new Blu-ray of Hell Ride and there is a pan right at the beginning that shows the differences really well. I'll need to try it some more to see how many side effects there are, but I think I could get used to not seeing jumpy images on pans.

Overall it seems like a really nice projector for the price to me, but the on/off CR stuff I measured pushes me much more toward the RS20 for my theater room, since I don't consider on/off CR that takes 10-15 seconds to get there to really be much of a feature (especially when there isn't enough CR before that to blackout to my eyes most of the time) and expect the close to 40k:1 native on/off CR I think I'll get with the RS20 to give some nice visible improvement. I may keep the AE3000 as my second projector to use in my bedroom and move to another setup though.
