Panasonic PT-AE4000 MSRP $1999 - Page 169

Some where in the menu of your BD player, receiver or the A4000 you have the option of having them just turn on, or on/off or other remote commands, depending. There are a lot of variables here, but the more CEC devices in the chain the more they can conflict with on/off of each other.

Yes, you can. Adjust the "V-AREA POSITION" to the desired position, and then save the lens settings to the 2.35 lens memory.

Does the 4K automatically switch between 2.35 and 1.78 depending on the source or do you have to manually do it?

Hi, just wondering if anyone in here made the jump from the ax200 to the 4000? Trying to figure out if the upgrade price is worth it. I enjoy the ax200 and can live with it, but I would also like to go 1080p soon.

I am projecting at 21 feet from a rear salamander audio stand on to a DIY 120" Wilsonart screen.

Is the 4000 just as flexible as far as placement?
I am looking to upgrade my screen situation anyway so can anyone recommend a nice screen to use with the 4000. 21' throw to a 120" screen. Light controlled room, with night time viewing 90% of time, other 10% being Sunday football. Also, 80% blu Ray,10% HDTV through fios and 10% PS3 gaming.

Thanks!

You can do it both ways. The automatic detection and switching between any two AR's of your choice is a new feature in AE4K. I don't use it, but I've seen mixed feedback on it.

Assuming your screen is 16:9, yes, that throw distance works. According to the Panny manual, which is linked on the first post of this thread, for a 120" 16:9 screen, the range is 11'9" to 23'7".

I got a Carada BW 110" screen from 13' out.

You may not realize it but the closer you get to the screen, the brighter the picture will be! As you move the projector back (which requires more zoom from the lens), the picture becomes dimmer.

I made the switch. I use my AX200 for a computer monitor and watch movies on my AE4k. I'm glad I upgraded but my throw is only 11 ft. At your distance I wouldn't recommend it. You need lumens, not contrast.

Thanks for the reply.

Would I be able to get a top not quality image on a 120" screen if I have my throw distance much less? currently, my plan is to have it around a 14-16' throw, but I have the room to put it closer, and the panny throw calculator says 11-23' for a 120" screen.

Anyone have any advice, especially if you use a 120" screen, though any advice is appreciated.

I do realize that, I get a nice picture on my ax-200 in normal mode, cinema 1 I find a little dim for my tastes. Gotta find out the real lumens difference between the 2 projectors in normal and "cinema" mode.

Check out the reviews of those two PJs on www.projectorreviews.com: http://www.projectorreviews.com/pana...200u/index.php & http://www.projectorreviews.com/pana...4000/index.php.

The calibrated lumen output is given in Art's Calibration sections, however, you should read the entire reviews. The Calibration sections are here (on a 106" Carada BW screen, at "mid-zoom" distance):

Anyone have any advice, especially if you use a 120" screen, though any advice is appreciated.

As a science major, I believe in the experimental method. I initially set mine up on a structure that could be moved and tried it out at varying distances from the screen.

The other approach is to debate "How many angels can dance on the head of a pin??"
Poly-sci majors are fond of this approach to problem solving. :>)

Finally got round to watching a movie on my 4000 tonight. Very impressed with the brightness in my light-controlled room. I even have a nice dust blob already! Thanks Panasonic!

Anyway, I'm not used to projectors so I did notice the black levels in the bars in 2:35:1 material did vary in brightness depending on the rest of the image's brightness. e.g. During bright scenes the bars were pretty washed out, and during darker scenes the contrast was a lot better in the bars and in the image in general. I'm guessing this is normal for the projector?

In any case, very impressed with the way this pj handles motion. Excellent stuff.

If you want to get rid of the 'pumping' of the black levels because of changes in brightness levels, turn off the auto-iris.

It there a calibration thread for the 4000u?

Yes: http://www.avsforum.com/avs-vb/showthread.php?t=1195573.

Just installed my Panny 4000 in the living room of all places. Non light controlled. Screen drops down in front of the old 50" plasma. Being a projector newbie - I scanned through many of the thousands of posts on the forums. Some of my observations:
1. The projector is bigger than I imagined it to be. I have an infocus 4805 in the basement - you could fit 4 of them inside the Panny. I know - I should have read the dimensions - but I just looked at the pictures not realizing the lens was like 6" in diameter. Got it up and installed before the wife saw it so its all good now.
Used a moderately high gain screen - 2.0 Draper - got it at an auction for a TV retailer that went belly up. 106" diag 16x9 - put it 16 feet from the screen - no hotspotting - screen looks great from all angles.
I was surprised by how little can lights in the ceiling affect the picture - the vertical lighting has little effect compared to low angle sunlight which absolutely wipes out the picture. Am getting a blind for the big southern exposure window over the entry door that kills the left hand side of the screen durng the day. But all in all I am amazed at how bright and vivid the colors are even in non light controlled room.
Used a Chief mount for the PJ - 1 1/2" pipe - thought the mount was total overkill until I pulled the PJ out of the box. Glad I got it now.
One question out of all this rambling - anybody else have challenges with HDMI #1 input on the PJ? I have not read the CD manual in its entirety - but I have 2 HDMI cables running to the PJ - they work fine on HDMI 2 & 3 - but 1 appears dead. Am I missing something?

I was told that the minimum distance for a projector is the width of the screen times the gain of the screen. Lens limitations notwithstanding. Worked for me - no hotspotting.

Hey congrats on the purchase. It is a great projector. However, with regards to your HDMI problem I can't say I had a problem there. I think that you might have a faulty input unless there is a way to disable it on the projector itself. Maybe someone else can chime in here. Good luck.

I noticed that my projector is suffering from the phenomen called shading, in fact when i look a completely white picture or image test like a gray scale ,it's possible to see very localized spots. on the lower left green stripe and other areas magenta streaks. This problem has also presented some of you?
The defect is more noticeable when watching movies in parts of solid,uniform type like sky, walls or wallpaper.
can it be a misalignment matrices or law lens quality ?
it's evident for example in the opening scene of the day after tomorrow ,on big white iceberg !

I suspect that you have a bad HDMI input #1. Be sure and double check that it was not cockpit error. Make sure that the cable is pushed straight onto the plug and fully seated as the HDMI connector design is not the most rugged thing in the world. If both of the other cables fail to work in the HDMI 1 port then you have a problem with that port. (Be sure cycle the power on either the projector or the source to assure that the HDMI handshake is occurring when doing the check!)

I will have to try this! What is the point of auto-iris?

Greetings everyone.

Can anyone advise how to turn on the x.y.colour option?

I recorded some clips using the panasonic TM700 with the x.y.colouyt feature enabled, and yet the option is not available during playback.

Thanks.

It improves dynamic contrast. I believe most people are leaving it on as it is almost unnoticeable on the AE4000 except for the increase in black level. It can added dynamic punch to scenes with that are bright lit. It also allows the AE4000 to have better shadow detail in dark scenes.

You pick your medicine and live with the side effects!

You should try it both ways while attempting to be immersed in the material (without looking for single picture attribute) and see which setting you prefer for just watching. You want to be a projector critic and watch only for any (and all) projector shortcomings, you need to be prepared to spend a lot more money to get a truly superior projector.

Thank you. I've definitely noticed the changing of the black level. This is a projector that is far from perfect, but still fantastic. The color uniformity was absolutely my first complaint, and then a dust blob at 7 hours. Probably there from the beginning but I began to notice it so I cleaned the projector today by following the simple instructions..

Here's a question for you all:

It was a total pain to take my ceiling mounted projector down to clean it today, since you have to then mess with the mount and positioning it when you put it up etc etc.

Is it OK to do the dust-blob cleaning with the projector still on the ceiling? It's upside-down mounted, so I can still remove everything I need with it upside down as long as I won't hurt anything? Hopefully some dust-blob experts can chime in!

WilliamG -- If you can get at the filter cover, with your PJ still mounted on the ceiling, then there is no reason to take it down. All you have to do is to remove the cover, pop the filter out, vacuum it (with a low suction vacuum) and reinstall the cleaned element and put the filter cover back on.

Thank you. However, at this point I'm talking about the dust-blob cleaning, which requires removal of the top case, 8 screws etc to clean the 3LCD mechanism...

Sorry. You are right. For removing dust blobs that are inside your PJ, the only way to get them out is to demount your unit, unfortunately.
