Optoma UHD60 4K Ultra High Definition Home Theater Projector Optoma UHD60 4K Ultra High Definition Home Theater Projector

I am happy with this projector (it is my first ever). However, when you do all the calculations for throw distance and screen size, make sure you take into account that this projector has NO keystone adjustment. At ~13', it can only project the image about 8" below the projector using image shift. So, if you have a high (or even normal) ceiling, it may not project the image low enough on your wall for your taste, or you may wind up having to mount it so that it hangs down into the room a bit. It seems that this is an image quality tradeoff that Optoma made (apparently keystone adjustment results in a reduction in image quality). It is working for me, but I can imagine that it would be a major drawback for some folks.
