Yup, that's what I understood/tried.

If you are right at or just above, then you might be ok. The center of the lens on my 8000 is 2" above the top of my screen. By using a combination of the joystick and v-area position in the lens menu, I have saved lens settings that allow me to take advantage of the automatic zoom for 2.35 content.

Thanks GWCR, I wish I knew how you got it to work. If you have a couple minutes to try this I would appreciate it:

1) Feed a 16:9 source to PJ
2) Load your 16:9 saved lens memory
3) Zoom using the lens menu (not the saved lens memory) so that your image becomes approx the width of your 235 screen
4) At this point do you have any gap from the top of the screen to the top of your 16:9 image?

Thx!

hey im currently interested in purchasing the 8K. Does anybody have an insight to how well it works with gaming? I play a little bit of FPS but mostly fighting and sports games. Any info is appreciated. I was gonna go with the JVC DLAX35 until I found it it was very noticeable, Im hoping that is not the case here. smile.gif

I got the best service that one can expect. You should get the same.....Good Luck

Hearing feedback like this just makes me feel even better about going with the Panny 8000. Very important to me to have the customer service behind my PJ. I will most likely be purchasing mine thru Project People as well...

Well since you asked I'm not really sure! I did have the Panasonic AE2000 with a smaller screen (aprox. 40"x 96") hanging lower than my current 54"x 120" When I upgraded to my new 8000 I noticed the keystone changed from -2 to -1. Then I upgraded to a larger screen which is much closer to the ceiling. Then after three adjustment I noticed the wall wasn't really strait. So I'm not really sure where things went astray.

235, I won't have time to get in the HT for a few days, but here is a POST in this thread from HMenke that I used when I was setting up. Don't know if you've seen it, but it may prove helpful.

When I can get in the HT, I'll see if I can answer your other question.

The more I think about it, I don't need to get in there and turn it on to give you an answer. Here is what happens. The 16:9 image fills the height of the screen and has pillar boxes on the sides. When the image changes to 2.35:1 (ie from a blu-ray menu screen to the actual movie), the 2.35 image is basically centered on the screen with the pillar boxes on the sides, and letterboxes top and bottom within the 16:9 space. Once the 8000 recognizes the 2.35 source the image "snaps" up to the top of the screen (from my v-area position adjustment), and zooms out to fill the screen.

Yeah, I know I'm quoting myself, but wanted to clarify one point. Make sure you are using the "v-area position" setting in the Lens menu, and not the "v-position" setting in the Position menu. Two different functions.

Thanks GWCR, I did see those posts by Hmenke. From the steps I outlined above I was hoping to determine if the zoom action drops your image and then the v-area shift raises it......or whether your zooming action does not drop your image at all. I realize you probably have lots of other things to do without me adding things to your list but if ever you do get around to it one day let me know. Thx


edit: Yup, using menu: LENS Control, V-Area Position

Hey Guys,
My lens center is also about 3-4 inches higher then the screen. When I set mine up I had to use all of the electronic vertical shift. I also had to tilt the projector down slightly. I set my keystone to -1 to compensate. I did not notice any change in focus or convergence from the tilt or correction. My auto switching now works flawlessly. Before I made the adjustments the image would shift down when zooming to 2:35. biggrin.gif

That sounds consistent with what I have seen. I was curious about how much keystone adjustments hurt the picture quality but it sounds like you found no loss in performance. Is that what others have noticed with keystone?

(New here. Please excuse any breach in protocol in asking this question. I've searched the forum, but can't find anything that addresses my question.)

I'm looking to replace my Sanyo PLV-Z4 with the Panasonic PT-AE8000U, and I have a question about brightness. My theater is completely light controlled. The projector is mounted 14' 9" from a 118" (diagonal) Carada Brilliant White screen (1.4 gain). There are three rows of seats which view from 13, 19, and 25 feet. But, the Projector Calculator Pro at Projector Central indicates that the image is too bright. And unfortunately, a REALLY bright screen will give me a headache.

So, my question is: Will there be enough control over the image (through Normal, ECO, REC709, or one of the Cinema modes, and/or the brightness control) to pull back the projector's brightness in 2D mode to make the image tolerable?

I'm pretty sure protocol would call for your post to be exactly right where it is.

Short answer: yes, don't worry.

If that calculator is going by the advertised 2400 lumens, don't worry about it at all. Under normal circumstances you won't be anywhere near 2400 lumens. If you have the 8000 turned up all the way to max lumens, your picture will look like **** anyway.

If you start with REC709 mode and do a decent calibration, you'll probably end up with 600-700 lumens. Your throw distance, screen size, and seating distance all seem reasonable. My setup is 17' throw onto a 110" 1.1 gain screen with seating at 14'. Room is non-light controlled, looks great when the sun goes down. The snow in Art of Flight is kind of blinding, but that's pretty much how snow looks in real life.

If you want to tone it down further, switch the lamp to eco mode. If it's still too bright, welcome to the future, you gotta wear shades.

Getting ready to mount my new ae8000u from ceiling of my room that is 17’ long X 15’ wide X 8’ high and a 133" 16:9 screen.
Projector central suggest throw distance of 14' to 26'.
my question is what is better closer to 14' or at the rear of room at 17' ?

Pros of Closer:
- More baseline brightness

Pros of Farther:
- Less noise
- Potentially better focus and convergence uniformity

I'm confused. The spec sheet says that you should be able to mount the projector 2 feet above the top of the screen for a 120" diagonal screen and be able to use lens memory. It seem some are having a problem getting it to work with only being a few inches above the screen. I'm limited to how high I can mount my screen due to knee walls, so the top of the screen will be 2 feet down from an 8 foot ceiling. Trying to get the projector low enough while keeping the bottom sight line above the front row is giving me a headache. This is all on paper btw, just planning.

Thanks for the feedback. I haven't got around to calling Panasonic yet, but hopefully tomorrow I can. Thanks for the tip on taking pictures. I'll make sure to do that before I make the call.

Can you point us to where you found this in Panasonic's docs?

Here is the link to download the spec file: https://eww.pavc.panasonic.co.jp/projector/extranet/main/products/ae8kat6k/ae8kat6k_spec.html

There are three sections. One for 16:9, one for scope, and one if you will be doing both scope and 16:9 using lens memory. I called Panny support to get their input, what a joke, just said that if that's what it say then that's what it will do. I told the guy that it
appears that some people are having trouble getting it to work if the lens is above the screen height, but he didn't know anything about that.

Yeah I remember seeing that chart. I think the focus of that chart has to do with throw distances but it does also refer to vertical offsets. It doesn't however specify whether or not achieving those vertical placement ranges require keystone adjustments. The very next page in their document mentions the maximum angle (30 degrees) with which the PJ can be installed. Maybe with a bit of trig someone could figure out if the vertical offset claimed in the table is solely due to the angling of the PJ (30 degrees).

Just my luck that my ae8000 arrives today and I'm laid up with full blown flu for the 3rd day running. Can't stand up straight so not a chance of ceiling mounting this puppy till at least tomorrow.

Putting the projector at the end of the room = no cables on the ceiling, but as Xank said, you will lose some brightness. I would go with this option.

My PJ is about 8" above the screen at a 17' throw. I can't get the zooming to work between 16:9 and 2.35:1 unless I use keystone adjustments. However with the approach below I'm thinking pulling the bottom of the screen forward about 2" may not be noticeable and avoids using keystone adjustments. Thoughts?

Not sure, But I would think that you would see the perspective difference as much as you would see the slight keystone. I would just use the projector's keystone adjustment. I doubt that you will see any noticeable impact on the image quality.

From you diagram maybe you could build a shelf so that the PJ is just in the screen space. I have a 12" riser with a couch as well, but with a hole in the wall instead of shelf. If the rear seats are forward just a nudge, the shelf will be mostly over the back of the seats (no head clunking risk)

Or slide everything (screen and all) 12" to the right to make room for the shelf

Just a thot

When you use the keystone correction you are losing pixels and it's impossible to achieve 1:1 pixel mapping.

You are forcing the PJ to downscale the image, then you are losing definition. This can be see easily with one-pixel computer-generated letters.

Actually my diagram has stripped out my soffit plans (lots more details in my build thread). I believe I would have room to drop the PJ and mount it just below my soffit and avoid the head clunking. I would prefer however to keep it higher up and tucked away nicely in the soffit if the picture quality doesn't suffer.

Good point, maybe I'll ensure the screen is mounted in such a way to allow easy tilting and if it looks odd then I could use the keystone correction.

So you have found your image suffers with keystone? Do you think the tilting of the screen would be a better approach?
