Maximum angle for a projector

Thanks everyone.


A shelf is against our current decoration design. We just can't do that.


I might check the tube solution, but is probably going to ruin the design as well. (There wasn't a projector in our minds when we did it some years ago.)


How about putting the projector below the table and projecting upwards?


The screen size will be around 100" diagonal (16/9)

Thanks for all the replies.


We have considered the mirror but it takes special care to keep it clean, affects image quality as you said and, all in all, we'll take the plunge and redecorate the room.


Now I'll investigate the best choice of projector. Lots of reading ahead.


Thanks again.

It has lens shift, so it's done by a little knob that you manually move so that the lens inside the projector is actually displaced, it's essentually an OFFSET-ON-DEMAND feature.


The 8700ub can do a 100" screen from slightly less than 10 feet back, but given the size of the projector's DEPTH from the back of its case to the lens, you might only get away with a 92" screen from your placement distance.


Since it will do a 92" screen from about 9 feet back, then that leaves you about 20 inches of space for the projector's case itself, this is based on the 10 feet 8 inch measurement of the room you gave. The projector's case is 16" long/deep, so that leaves you 4 inches of room behind it which should be enough for the AIR intake to get enough air to cool. The cooling exhaust is on the front, so no worries there.


So I would shoot for at least a 92" screen if you can, the bigger the better, I personally wouldn't go smaller than 92" in your setup, but you could do an 84" if you really want it smaller I suppose.


Buy the projector first, then the screen last. You can project onto the wall ahead of time to make sure you have the placements correct and to ensure you can get the screen size you want/need.


A 92" 16:9 screen is 45" high and 80" wide. So if you mount the screen 30" from the floor, then that means the top of the screen's projection area is 75" off the ground, or 6 feet 3 inches. Assuming you mount the projector nearly flush to the ceiling, the center of the lens will be about 9 feet from the ground, give or take a couple inches.

Also it should be noted that there is no exact STANDARD height for mounting the screen from the floor.


I personally prefer it lower than most people becuase I lay down on the couch sometimes, in my case my screen is mounted about 25" off the floor.


Most people would want to mount the screen somewhere between 30" to 36" off the floor from the bottom of the screen, I would personally recommend about 30" depending on your seating type, but you can go up to about 3.5 feet if you really want it higher.


It is a personal preference sort of thing in combination with how you sit more than anything else. Going too low makes it so that if you are in a recliner, your feet can get in the way of the VIEW from the bottom of the screen, but that's generally only if you go below 30" or so.


That is why you should buy the projector first, and use a ladder or something to temporarily place the projector near the ceiling as if you mounted it, decide what you want, then buy the mount and screen and finalize the setup after you spend some time watching the screen at different sizes and messing with the projector's placement.
