JVC DLA-X5900WE Ceiling Mount without Pole?

Recommended Posts

I have finally got around to mounting my JVC DLA-X5900WE Projector using the ceiling mount Peerless AV PRGS-UNV Mount.

But I can't seem to get a square image with only using Lens Shift and no "Keystone Correction".


Ceiling Height: 2.74m

Lens Distance from Screen: 3.8m

Rows: 1


Only way I can get the image 'square' is using Keystone Correction and changing the angle that the projector sits.

If i were to level the projector and use Lens Shift only, the image just reaches the ceiling height doesn't go any further down.


Any ideas? or is using an extension pole the only way to move forward?

If so, any recommendations for a extension pole mount? Peerless AV have seem to discontinued all of their extension pole mounts.

something doesn’t sound right if can’t lower image further from ceiling ?


have made sure you have set the installation in the menu to ceiling front ? Ie image is inverted ?


should be no need to use keystone which creates digital noise. instead make sure screen is vertical check with spirit level all over and make sure projector is level - check with spirit level 


below is the calculator can check, has max shift range and such




as far as extension column, seem to be still there and various placed to buy from

Definitely got the right settings in regards to mount type in the settings.


Basically this is what I did:

1. Lens Centre on the projector menu

2. Used Lens shift to move the image as far down as possible


This gives me max lens shift which only brings the top of the image inline with corner of ceiling/wall.


Trying to fit a 120" screen which is possible. Looked at the JVC calculator, maybe just not possible without a extension.


Not sure if this is normal or not.

I moved my projector up and down to work out what size extension pole do i need.


To achieve the following parameters:
Ceiling Height: 2.7m
Image Height from Ground: 85cm
Image Size (Diagonal): 120"
Aspect Ratio: 16:9
Lens to Screen Distance (Throw Distance): 3.63m


I had to adjust the projector height to 24" from ceiling to achieve the above parameters, this was with Lens Shift set to Max.

Does this sound about right?
