Panasonic PT-EZ570UL
Projector Specs
Current Dealer Prices
I am looking to rear project a vertical image that is 72" tall x aprox 44" wide..

Distance from screen to projector is about 5'

I have no finalized my projector choice but currently the panasonic PT-EX570UL with .8:1 Fixed throw lens is my choice (im open for another suggestion) need 16:10 - 1920 x 1200 , 5000 lumens Min.


I was planning on aiming this projector up and reflecting the image using a first surface mirror. I would prefer to just put the projector on its side but i heard that isnt recommended.

im having trouble keeping the mirror small and not having the projector be in the way of the reflected image.

Any advise or suggestions would be greatly appreciated.

That's a lot of lumens for a small image, but should be bright and vibrant.

My biggest concern is the projector placement. You must download the owner's manual and ensure that placing the projector in the orientation you are after is feasible with that unit.

You must always allow manufacture recommended, or more, airflow. So, no setting the projector down in any way that covers vents.

For rear projection, a covered area in the back that doesn't let light in will drastically improve image quality - this area must allow enough airflow around the projector to leave a quality image.

Your idea sounds interesting, but some homework and digging will be necessary to ensure it all is allowed.

I'll do it on this one...

YUP! You can do this, so that's great news.

May be tough to keep that mirror as small as you want, but you have to have the space to get the size you are after and total lens to screen distance will remain around 5' or so.

Ive been playing with the angles and I fear the mirror will be very large (bigger then 12"x18") and the image will still be partially blocked by the projector itself.. I think I may just install the projector on its side. in an enclosure.. pack it will massive cooling and hope for the best
