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 don’t know why this projector gets lots of good reviews but I really don’t like because of its picture quality. It was super grainy with bad color. It almost felt like I was watching a bigger version of a low quality video. And the machine is heavy and extremely hot when projecting. I don’t think it’s anything that I expected. They shipped me with one without lens cap so I had to buy a cap myself. Be careful if you have a high expectation on picture quality. This is no way what you want.

As few other reviewers pointed out - picture is grainy, dim around the corners, sharpness and keystone controls are useless, cheap packaging, flimsy plastic case that does not inspire confidence, no mounting holes for ceiling mount, remote control layout is unintuitive - good luck adjusting anything with lights off. Bought based on glowing reviews - should have done more research.

Dont buy this. Firstly I bought this projector on 1/16/21 for $694.48 so it has experienced about a 50% price increase while slowly moving towards being outdated. Aside from the price this thing is just a pain. Its very dull, loud, cant run for long, will heat an entire room, but most importantly it will fail for one reason or another and when it does there is only one service center in the country which is in CA.

I upgraded from an older, albeit top of the line (multiple thousands of dollars) projector to this one, and I have to say its very impressive at this price point. The picture quality is amazing and is compatible with the new PS5 games. Set up and control is simple. A small negative is screen adjustment is a little basic, not a huge issue, but I have a theatre room that has a painted outlined/bordered wall for a screen so I can get it to fit perfectly. I would love a response from the company because this troubling issue is happening when I power on sometimes and it wont connect to the input, sometimes it will load and skip, other times stay steady with load/searching text; I have to navigate thru other input options to get it to sync up and finally load the PS5 input. Would recommend tho after trying a few other projectors around this price point.

Great picture quality. Would be even better if the projector could be connected by Bluetooth.

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.

We had the Optoma HD71 and upgraded to this one. What a difference. We use an Xbox to run all our streaming serves, and Blurays, so everything is in 4k on an 100 inch screen. Great picture quality. Well worth the money, we will use this for years to come.

This is a GREAT projector, especially for the money. Its quiet, can be used in a room with the lights on, and has a crisp picture with good color. The ONLY thing Id say is that the refresh rate blurs rapid movement in video games such as call of duty or sports games such as Madden. Youll get used to it fairly quickly, but it is an adjustment and you have just a beat less time to react. Movies HD and above look absolutely fantastic.

Nice picture and brightness... pictures are projecting 135 inch screen on a regular painted wall. Still need to put screen up, but it looks pretty good as is. I expect the quality to improve with screen.
