Absolutely love this projector. Seller shipped item super fast.

My second BenQ, I love it.

I’m giving this a 1/5 until BenQ fixes the firmware issue that causes the projector to drop the source intermittently and at random. This is a known widespread issue.

I have had a BenQ projector (W1070) for five years. When I heard that a 4k direct replacement was coming (HT3550), I placed a pre-order as soon as available. I just received and installed today. First test was the 4k BumbleBee video. Amazing clarity and brightness with very little adjustment necessary. The dynamic iris and HDR make a significant impact on movie presentation. Second test was HD content with Pens vs Islanders first round hockey playoffs great picture, even with fast paced camera panning. So far this HT3550 is everything the W1070 was when I first purchased, but with the added 4k and dynamic Iris and HDR. Very pleased with initial experience. Highly recommend.

Sharp high-def images, very pleasing to the eye.

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’ve had this projector for about a year and I absolutely love it!! The picture is great but don’t cheap out on a projector screen then no matter how good of a projector you have the picture won’t be perfect. It’s a little noisy but when I’m watching a movie I never hear it. I recommend dynamic iris on high, color enhancer & pixel enhancer at a 2 or 3

I decided to upgrade from my 5yr old W1070 which has never let me down. All I can say is WOW, the HT3550 is a day and night difference. Im not sure whats to come in 5 more years but Im confident BenQ will be on the top of my upgrade list...again. (the pics are in a fully lit room without any projector adjustments)

This was the projector Ive been waiting for . Got the Epson 8350 seven years ago, still works great. Replaced the bulb twice but now was the time to upgrade. It was very quiet located in the back of my movie room. Opened the HT3550 with much anticipation, mounted it on the ceiling but due to the limited throw rate, it had to be mounted right over my first row of theater chairs. I have a 92 screen. So disappointed with the loud fan noise overhead. Loved the excellent picture quality, especially the black level . Anyway thought I could live with the fan noise and went through normal setup but about one hour into the process the bulb shut down, projector turned off and the red TEMP or LAMP light came on. Called Benq tech support and was told that should not happen to a new HT3550. So I reluctantly returned the projector for a very quick exchange from Amazon. Thank you. Set up the second HT3550 and started watching movies. This time about two hours into the viewing, the bulb just turned off without the TEMP or LAMP light coming on. Green power light was still on. I let the projector cool down and when I turned it back on it worked fine. Watched two more movies that evening and everything went well. However, the next day, when I tried to turn on the projector, I could not get the HT3550 to turn on. Yes, the green light(s) were on so I knew I had power. Tried everything using the remote and the projector panel. Went through every troubleshooting suggestion I could find. Never could get the projector to turn on. Checked all wiring just to be sure. So I returned the replacement projector.

I owned at least 8 projectors in my life time and this is the best projector I ever owned. The 4k on this is extremely sharp the colors are vibrant and the image brightness at 2000 lms is bright enough for my semi darken room. It throws a powerful image I found that the cinema mode is the best. This projector is not noisy at all very quiet. The only issue I have is that it throws a lot of heat wont notice if mounted on the ceiling I have mine next to me on a table. Other than that I love this projector.
