Worst electronic part I ever purchased, projector went bad in less than 6 months. Ha F screen is all shaded dark

Love the projector. Looks sleek and picture is amazing. It’s just pricey; took all my savings but I needed an upgrade in my media room.

I cant believe home amazing this picture is. Combined with a 4k ultra hd bluray player with HDR10 and a 4k receiver the picture has vibrant colors and deep blacks. Even with regular bluray movies the picture is awesome, but nothing beats a 4k movie. Its always better to watch a movie in a dark room, but you can with alittle bit of ambient light coming in. I would much rather buy from Amazon, theyre return policy is much better than anyone else. I did have a hard time positioning the projector to the screen. Just remember the lense needs to be directly placed in the middle of the screen. I have a 120 inch screen and sit 20 feet away . its a perfect size for that distance. The projector comes calibrated already from BenQ which is nice. You can always play with the picture options to your liking. I had some video lag with the voice with the lamp set on eco mode and vivid mode. As soon as i set it back to D.Cinema and lamp at normal it went away . Google and forums on BenQ troubleshooting really helped me alot. For the money and the options you wont find a bettter picture . *****Update***** Ive had this projector now for 8 months and have had absolutely zero problems. I still love the picture it projects. Bluray movies looking amazing, but I only buy 4k movies.

I have been an installer and enthusiast for over 20 years. My first install was a giant Barco RGB projector which put out a whopping 800 lumens. Projectors have come along way in every aspect. I chose this projector because I have a room that I can control all the lighting. I am able to make the room almost 100% black. This projector is absolutely stunning considering both the size and price point. It handles 4K material flawlessly. I must note that I installed the projector and used a fiber optic HDMI cable so I do not lose any signal along the path. I am shooting this onto a 100 fixed screen with a gain of 1.1, and it looks absolutely amazing. The lens shift is very helpful but note it is only vertical. There are multiple reviews out there with preferred settings to use to achieve maximum picture quality. So I will add mine. Lighting controlled room: Dynamic Iris: High Light Mode: Eco Picture: Cinema (If you set the 4K to Auto this will auto switch to H10 when 4K material is detected) Brilliant Color: On Wide Color Gamut: Off (I know I will get dinged for this, but my family enjoys a slightly brighter picture) Silence: Off We have viewed several movies from DVDs, to Streaming, to 4K Blu-Rays, and this projector will bring out the best in all of them. With that said, please keep in mind that a DVD at best is only 480p, which means it will look the worst on the projector, or any other 4K display. The only gaming I have done is on a regular PS4. I did not notice any lag, but I am not a competitive gamer. Finally, I must address lag from an audio perspective. The video is stunning and the visuals will blow you away when this is set up correctly and you are viewing good source material. There is inherent audio lag/delay when using a projection system depending how far away your projector is from your receiver. In my case, I purchased a 50 fiber optic HDMI cable so I could run it through the walls. Although fiber optic cables have more bandwidth to transport the entire unaltered signal, they are not any faster than a copper cable. Physics still apply here and the signal still has to travel the length of the cable. Not to mention the conversion to and from light at both ends. For my system, the magic number was 50ms of delay on the audio. This syncs up perfectly with the image. I would assume there is a calculation that can be found online for this, but I simply used a little logic and some trial and error. There is roughly 10ms delay for every 10 of cable. You may never notice it if you are running cable directly to a TV, but its there. When your image is 100+ inches, it is hard to ignore. Finally, I have viewed an installed several projectors that where 10 - 20 times more expensive than this projector. This is the happiest I have been with a small format projector, and I do not feel as though I am losing any performance. I know there are bigger and better projectors out there, but I challenge you to find one for less than double the cost. As with all reviews, please take this with a grain of salt as this is just my experience. I would recommend this projector to anyone who asks.

I own a BenQ projector that I bought 6-7 years back which still works great. Decided to upgrade to a 4K projector and chose this. The picture quality was Amazing. It was a natural progression from 1080P to 4K - till it lasted. As some have observed, the projector stopped working after a few movies. Except for the Green power light blinking and turning on, the projector is basically dead. No sound (of the fan), no light. Hope BenQ finds the issue and fixes it so future customers dont have to go through this...

Only real dislike is that superimposed images and information, still or scrollng are jittery and it really annoys me. If is audition a 4k projector that does not do this then I will buy it if the price is not ridiculous. This may not be the fault of the 3550 but the broadcaster, that is to be determined.

Mounted at 11 feet from screen and it will only fill 80% of a 135 screen. Ceiling fan prevents mounting further back. I now have to move the ceiling fan to get it to the 13-14 foot sweet spot. Not BenQs fault. However a shorter throw projector could have handled the 11 foot distance IMO. I will try mounting it behind the fan first to see if it can work at 16-17 feet and still be bright enough. The pole mount places the projector below the fan enough to work. I can remove the light portion if needed. Initial picture quality is fantastic on HD, have not tried 4K yet. Color is great out of the box. Brightness better than expected with only 2200 lumens. With over head lights on screen was bright. With lights out its amazing with very dark blacks. Moral of the story, read the specs carefully and figure out mounting option prior to ordering. Otherwise the projector is a winner out of the box. Will update review in a couple weeks once we have tried out 4K and 3D.

This was the best economically priced 4k projector I have bought. The picture quality this projector lens puts out is simply impeccable and enjoyable to watch on a big screen. Plus I love that both hdmi ports are 2.2 hdmi quality

Its awesome i love it for my movie nights

I will put a lot more effort into this review as time goes on, however, it takes time to collect the data. The clarity is crisp as all hell and is beautiful. This is also me talking about this while projecting on a non-treated room wall. It will only get better from here. The brightness is great if its dim-lit or dark, but with daylight shining in, youll still want a tv over this. I moved mine to the corner of the room and still use it when the sun is glaring in.
