MOUNTING Questions for NEW Projector - Needs to be RIGHT!

I just bought the Panasonic PT-AE4000U after reading rave reviews.

I have a current dedicated home theater room and system. This will be an upgrade to my 4 year old Acer 720p Projector - so I am hoping to be wowed!

I want to make SURE that I setup this new unit not only correctly - but OPTIMALLY!

Please view the pictures so the following makes sense:

1. I have a space cutout in the ceiling for my current projector (this was done when the room was finished and made into a HT room). As you can see, I have a very unique/odd way of placing the projector. I use a wood peice, and rest it on bolts with cardboard in between. This serves me 2 purposes. First, it lets me level the projector - but SECOND and most importantly - when I had the projector bolted directly into the ceiling - the subwoofer (which is RIGHT below it - and will not work anywhere else) caused the picture to SHAKE! The cardboard absorbs this and there is no picture shake whatsoever.

If there is a special holder/mounter that deals with shaking and leveling I would love to know about it - so I can have my projector installed in a professional manor rather than this jury rig.

2. As you can see in the photo - the acer projector is as HIGH as it can be while being as FAR back as it can be - to fill my 120" screen. This also helps as its projection angle is very far down - so you can see that it is slightly tilted UPWARDS.

I am hoping NOT to have to do this with the panasonic - as I read it has far greater adjustment controls.

3. I have never 'calibrated' a projector OR TV for that matter. I am curios about recommended HD Discs that I can get to help me with this - something that would be very user friendly. Also - is there perhaps a guide to tuning THIS specific projector (or should I just google search for that)? I have my computer system hooked into the projector - so something I could DOWNLOAD would be ideal!

here is a direct link to the full uncompressed photos: (too big for this forum!)

Don't know about the mount, but you might want to host the pictures here on AVS. Many (most?) people are reluctant to click on an external link. Lots of SPAM and Malware out there, you know.

click 'Go Advanced' on the 'Message' box and use the 'Paper Clip'. Opens a small new window that allows uploading attachments.

I suspect that a big part of the issue is the mount. I used that type mount initially on my Epson and found that it was very sensitive to vibrations. I went shelf mounting off the rear wall, but others have recommended the chief mount as something that is more stable and which has damping designed in.

How important is leveling the projector perfectly?

Does anyone know if this projector has settings that would allow for me to adjust the picture if it is not perfectly level?

I know it have horizontal/vertical shift and keystone - but do those accommodate for not being level?

It is VERY important that the projector be plumb, level and square to the screen.

If the projector is not square to the screen one side of the image will be taller/shorter than the other. Keystone can be used to correct for the "tilt" of the projector either forwards or backwards but is not desirable as it can affect image quality. Lens shift will not actually correct for out of level, it only corrects for projector placement.

Most of the quality mounts Chief, Peerless to name a couple have adjustments to help you correct for tilt, level, and plumb. They are more expensive than other mounts, but they are worth it.

If you are confused on what mount to get I suggest you give Projector People (a forum sponsor) a call and get a recommendation from them. I got my Chief mount from them and they were very helpful in helping me decide what I really needed.

Good luck.

Regards,

RTROSE
