It was for our church building and it is working great. Better than the one we had before.

The first time the projector was turned on it produced these vertical lines internally. It could be affected by the housing. I noticed when I was pushing the buttons on the top surface to adjust the screen the lines would start to disappear when pressing a button. Pressing down the top surface made the lines go away, something’s the lines would stay away for an extended period of time. The lines always returned. Additionally the projector lens seemed to slide out of focus, ever so slightly, to where the picture was just out of focus and slightly blurry. I had to adjust focus about three times during the length of the very first movie we tried using it on. I was excited about the product but my nervousness with projectors in general was only validated using such an expensive one and having similar issues to a cheaper one.

I returned the item well within the return time window and it took much longer than usual for the return process.(Buyers beware!They charged quite a bit on the return.)The projector is decent but didnt work with my pioneer reciever. It is seriously picky on compatibility with hdmi cables.

Replaced an older Optoma projector with this one. Picture brightness and clarity are exceptional!

The I ordered had multiple connections at the back. The one I got only have 2 HDMI and a VGA connection

Using with a 120 screen 15 feet away. Flawless. Love it !

Best projector Ive ever owned!

Picture is nothing short of astounding. I have the projector mounted in a bright living room and can easily watch during the day with the curtains drawn. I would love to give this five stars..but I cant because every once in a while, it does some kind of thing where the power indicator flashes purple and the power button on the remote is ineffective. Never had this issue with my old HD 27. Anyhow, at these times, I have to climb up on the couch, pull out the power plug and plug it back in in order for it to work. This sucks even more because it often moves the mount so I have to refit the picture to my screen. Wish I knew a fix; but for now, Ill just expect to have to go through this nonsense once or twice a week. Otherwise, its an awesome projector!

Great projector for out side movies

There are some scratches on the lens. The shape of a video is funnel-shaped and cannot be rectangle-shaped. The Keystone correction cannot change funnel-shaped to rectangle-shaped. Keystone correction cannot make funnel-shaped to rectangle-shaped. The projected image is unbalanced.
