DLP ceiling mounting query
« on: November 22, 2019, 12:40:00 PM »
I want to ceiling-mount my Mitsubishi - its optimum 'table' projection position is right in the most annoying place.
The manual says it can be used with the "Mitsubishi PROJ-UCM" adapter (on which I can find no useful information).
But the manual also says: "Slanting the projector more than 10 (right and left) or 15 (front and rear) may cause trouble or explosion of the lamp."

So how can it be used in a ceiling installation  - wouldn't that count as slanting it 180 ?
What happens inside when you slant it, that does not happen when you turn it completely upside down?

Does running projectors upside down shorten the lamp life at all?

I think slanting may refer to "keystone"

Look the model up on projector central... it will give you the correct offset so you would ideally not have to tilt it (so no vertical keystone needed). It's also mentioning left/right which also makes me believe it has horizontal keystone correction of some sorts too... again, only needed if you are not mounting it dead centre or perfectly perpendicular.

"explosion of lamp" ??!  honestly never heard that warning before, but I suppose it could pose a risk if the keystone correction is manual (where the lens physically shifts).  I seriously doubt digital keystone will have any effect, besides degrading the image.   The latter being a reason as to avoid keystone if you can.

Any universal projector bracket should work, they are pretty versatile.  Just make sure it drops to as low as the offset advises and can handle the weight.

Ps: If it has mounting holes at the bottom and allowes you to flip the image on the menu, it is designed to be safely mounted.
