With the 4000 also being LCD, is this a factor at all?
Can you see lots and lots of shadow detail, when using your dimmest theater calibration mode when the room is totally dark?
I'm slightly worried that I may spend 2 grand on this pj, and still be disappointed with shadow detail.

Using my old Sharp 12k mk2 projector and High power combo, I definitely notice a loss of ANSI contrast on bright scenes, but black levels and on/off contrast remain very similar to my old bat cave when it comes to low light scenes. I'm not accusing any particular person of exaggerating, but I'm just seeing a lot of posts lately that seem to suggest that you might as well buy a 5 year old 1000:1 contrast projector if you don't have a bat cave. With my Sharp 12k, I can easily notice the huge contrast gains when I switch the iris down.

Using a "new" projector like the PT-AE4000 one doesn't need a bat cave anymore to get amazing images. For those who decide not to buy a new projector because they don't have a bat cave are really crazy.
Projectors 5 years + may have needed a bat cave to look good, todays projectors don't. Im not advocating front projection with lights on or in daylight hours, even though that doesn't stop many buying a projector.
I still think for the best image you want full darkness, bat cave or not.

Hi Smarty-pants

When I get my AE4000 maybe you can swing by medina and check it out. I might even be open to doing a meet, because it's a lot of HT guys in northeast Ohio.

Ive calibrated with Spears & Munsil disc on my BDP-83 and using Normal on high lamp. I have more then enough light on the sheet
I see every bit if shadow detail, its better than 3D
You wouldn't use the dimmest theatre mode on a screen as large as I use, maybe a 120" would be max on those modes.
I had the 3000 for 1 year, I say the 4000 kills my old results.

Of course the theatres use curtains, and some more expensive setups to as well. It would seem like there would be more people like me looking for a bit larger screen, and willing to take 1:00 to mask before hitting play. I'm rambling, mostly looking to see what. if anything, i'm missing.

One of the reasons why I love the AE3000 and will love the AE4000 (this Thursday) is the ability to shift the image. I only have to mask the bottom of the screen and move the image to the top of the screen digitally a the press of a button. I use a velvet curtain with hooks on each end to support it at the same level each time and it takes less than 5 seconds to do it. Most of the time I leave it masked and view smaller 16:9 for SDTV. For sports, I remove the curtain and Zoom to fill my 100" 16x9 screen.
I think it is the best of all worlds and this projector makes it easy.

Thanks for the feedback Murray. That's good to hear on the brightness issue and shadow detail.
I wouldn't be using that big of a screen anyway. It'll be more like 100x42.
I was just curious how the pj fared when fully calibrated to 'theater dark' settings.

BTW, how far from default settings did you have to go to get the picture just right. Which settings were 'OFF' the most, and did you have to change the gamma settings?

Thanks again...

That would be annoying.

As you know the Chief RPA is an excellent product. So easy to pull the pj down from the ceiling. And owners of the BenQ 7700 appreciated that (a bit of an inside joke).

And welcome to AVS.

Can anyone confirm having success (or problems) hooking a PC to their new projector via VGA? Anything special you had to do other than set the output to 1920x1080 60hz?

I am limited with putting a ceiling mount in my room. If I were to go with the Panasonic PTAE 4000 the good news is its seems very flexible in placement.

However it does mention something like a recommended almost 20 inches of ventilation from back and front of the PJ per PTAE 4000 manual.

Thus I need to be able to place this PJ on my back wall.

Question:

I found an omnimount projector mount that might work, but only gives approx 14'3 inches of back clearance.

Here is a link to the projector mount I am thinking of

http://media.omnimount.com/attachmen..._Specsheet.pdf

Could this work, or are there other wall mounting solutions out there you can think of?

Thanks

Yes - This takes away over a foot in my throw ratio I had in mind.

Here is the wording out of the manual:

"Do not cover the air exhaust/intake ports or place anything within 50 cm (19 5/8") of them."

Anyone that has used a wall mount arm with the PTAE series, if you can recommend something that can work for us wall mounters. Shelf is out of the question for me at this point.

When I boot up Windows XP while hooked up via VGA the splash screen is formatted for the screen but when Windows comes up 1920x1080 is displayed with the sides squeezed in. However, when I've previously boot up the computer to my HDTV and use a VGA switch to switch over to the AE4000 1920x1080 displays properly. I haven't investigated this any further since this is actually the method I will usually boot up with so It's really a non-issue for me.

hmm I think I have a dust blob in my new PT-AE4000 :/

It's my first projector, but tonight I noticed a very very faint dark blue circle during dark scenes. From what I've been reading online that appears to be a symptom of a dust blob.

Calling projector people tomorrow to find our what their policy is with that.

I am not sure if this helps, but I ran into the same thing the first time I connected my htpc to a projector (AE900) via HDMI. In the control panel software that comes with my video card, I adjusted the over/under scan to 0%, and that caused the display to use the entire panel. In your case you are using VGA, so I am not sure if my suggestion is applicable.

BTW, there is a noticeable improvement in PQ when using HDMI instead of VGA. I didn't think there would be, so I was pleasantly surprised.

Dust blob!! That's not good news considering the way they touted the new partially sealed light path! Perhaps it was there right from production? How many hours are on this projector?

You can try to focus on the dust blob to confirm it. Pause a dark scene and adjust the focus to see if you can bring the blob into focus.

How is the lens shift on these? What percent does it move vertical and horizontal, for example does it go 50% vertical and 50% horizontal?

Mechanical lens shift is up to 40% horizontal and 100% vertical. See page 15 of the operating instructions, which you can download here:
http://www.panasonic.net/avc/projector/manual/

However, if you want to use a 2.35 aspect screen in a constant image height (CIH) setup, then the projector lens needs to be no higher/lower than the top/bottom of the screen. Otherwise when the lens memory zooms 2.35 content to fill the screen, it won't be able to shift the image far enough vertically.

Very true. While I have a bat cave, we have a almost always have a row of recessed lights on (but dimmed) across the seating area and that is about 10-12 ft from the screen and the image is extremely enjoyable.

Does the PT 4000 render a great 2:35 image on a 2:35 screen or is it just so so suggesting that viewing 2:35 on this projector might best be done on a 16:9 screen? ?

Admittedly I'm still trying to fully understand the CIH scenario.

Thank you.

It's been nearly 24 hours since I was on here, and now it's 3 pages later.. but I'll go ahead and respond anyway. Bob summed up the details probably better than I could on the last page. This discussion really is better suited for the CIH subforum (you do realize there is an entire subforum for CIH discussion, and there is no shortage of zoom vs lens discussion there).

I've done a fair amount of reading in the CIH forum myself. My conclusions are that there is no right choice for everyone, zoom or lens. They both have advantages and drawbacks. The largest drawback to zoom, however, has always been that it was a PITA to do. With Panasonics new lens memory, however, they have elimated that, which in my book puts their zoom method in front.

As far as picture quality, there are even pro's and con's to each method for that. Some will say they can see pixels when zooming, although on a Panasonic I'd guess they would have to be sitting pretty darn close to a huge screen to see it, closer than would be comfortable to me. I will report back once my 4000 is installed and let you guys know if I can see pixels at my seating distance and screen size (based on what I've read I know I won't) while zoomed for CIH.

The light loss argument actually isn't usually as bad in real application as people often tend to state. Sure, your losing pixels (made up ones btw) of light, but in reality it isn't usually as much as it would be in theory. The reason is because when zooming your also increasing the light output, making the real difference often 10% or so. I suspect the AE4000 will be plenty bright enough for me to begin with, so I don't have any concerns about losing a little bit of light output. If I do, I will always have higher lamp settings or picture settings I can switch to.

So in summary, the BD disc only has 800 pixels (according to Bob, I didn't do the math) of picture height on it to begin with (for 2.35), and that's what you'll be displaying on your screen. You aren't losing anything in that regards. So to clarify my previous post, the more important factor is the source material not necessarily the projector. Your displaying 16:9 material on a 16:9 projector, so nothing is gained or lost. There are no 2.35 projectors or source material currently available, at least not on the common market that I'm aware of.

Thus I need to be able to place this PJ on my back wall.

Question:

I found an omnimount projector mount that might work, but only gives approx 14'3 inches of back clearance.

Here is a link to the projector mount I am thinking of

Could this work, or are there other wall mounting solutions out there you can think of?

Thanks

Quote from the PT-AE4000 Spec File (ae4k_sf.pdf):

================
1. Never place objects on top of the projector while it is operating.

2. Make sure there is an unobstructed space of 100 mm (3-15/16˝) or more around the projector's air intake openings.

3. If the projector is placed in a box or enclosure, ensure the temperature of the air surrounding the projector is between 0°C/32°F and 35°C/95°F. Also make sure the projector's intake and exhaust openings are not blocked. Take particular care to ensure that hot air from the exhaust openings is
not sucked into the intake openings.
===============

There is also a drawing on this same page which shows a 4" clearance on the sides of the projector. Intake is on the rear panel. This drawing also implies that there should be four inches on top. (However, if you have studied the projector at all, you will know that the knobs for the mechanical vertical and horizontal shift are located on top and you might need far more than 4" to be able to adjust them.) The exhaust for the projector is at the front. I would assume that 4" clearance is also required here. The drawing assumes that the front is open.

From the spec file, the PT-AE4000 consumes 240 watts of power. If you want long life out of it your mounting/enclosure method must assure that the heat can exhausted from the area of the projector so that you meet the air temperature parameters of paragraph 3.

I must admit that I can not remember exactly where I found this file. Last month, I spent an hour or two exploring both the US and the Japanese (English language side) Panasonic websites looking for information and found five PDF files of technical and sales information.

On the batcave subject, has anyone found any dedicated threads dealing with minimizing light reflecting on the screen? I found lots of acoustic information threads, but not on light reflection, or I wasn't looking for the right subjects. I would like to clean up my room before I get a new projector.

Keep in mind that this projector runs at least twice as hot as the AE-900. I can't speak for the heat produced by the AE-3000. If you put your hand up to the exhaust vent, it feels like a small under-the-desk heater, though it does run a bit cooler in eco-mode.
