BenQ TK850i True 4K HDR-PRO Smart Home Entertainment Projector powered by Android TV | 3000 Lumens | 98% Rec.709 | Lens shift & Keystone for Easy Setup | 3D Projector for Binge Watchers and Sports

The picture quality is good. With 4K, pixels are become invisible. Text is smooth. Very noisy fan, even in the Silence mode (no 4K mode). This doesnt bother me much during movie time. But I also use the projector as secondary monitor, and the noise is very annoying during daily use. I came from a BenQ W1070. I was hope that this HT3550 is a direct replacement. However, not the same throw ratio with W1070. I needed to request installation service.

It’s a really good projector the colors are rich and vibrant, works decently in a light room but You will definitely want to close the curtains to get the best experience, I havent tried gaming but movies on HDR 10/10

Stay away! Ever since Ive had this projector, 3 or 4 out of every 10 startups only half of the screen works and I have to turn it off (it actually turns itself off) and restart it. If that was the only issue, and its a big one, I suppose I could live with it and I have thus far. Now, with just over 200 hours on it, a bad aberration has showed up on the bottom left of the screen and its not the lens nor my actual pull-down screen. Definitely a internal issue and it can be seen during bright scenes or when a uniform color is displayed. Extremely annoying, something that once you see you cant unsee. Im crossing my fingers that I can get BenQ to RMA it even though it was purchased from a third-party seller through Amazon. I wouldnt take the risk if I were you!

Its great for the the price.

Well guys what can I say about this projector? My previous projector was a viewsonic 720p native which I purchased from a co-worker, who had upgraded his screen and projector (he got another viewsonic and gave me his gently used screen and projector). I had been waiting over a year to upgrade. I went from wanting to get the TK800 when it first hit, to the LGs fancy portable one, to the xiaomi mi to you name it...I have a small apartment (its mounted a little over 8.2 away), so the throw was important to me, and I had been tired of not making use of the projector screens size (a homegear 110). Im a novice when it comes to all the jargon and terminology, however, I do know what looks good. Im a computer gamer and several yrs ago added xbox and ps4 to my list of addictions. Ill say that this projector has blown me away. An amazing image, no light spills on to the ceiling or anywhere that its not meant to be...fan noise is reasonable as well. Because Ive yet to buy a sound system, Ive been using projector speakers, and honestly Ive been impressed. Im definitely not a fanboy, but Ive certainly been won over. Dont take my word for it, look at my pics and decide for yourself. If youre on the fence, hop off and buy the darn thing. You wont get a single regret from me.

Not so good in a light environment...But in a dark room, this bad boy puts out a beautiful image. Dont think youll find better at this price point (researched for two months before choosing this guy). My only complaint was the fan noise. At first it was a bit distracting when watching a movie, but after a few days I got use to it. Projector mounted 3 feet above my head.

Love this projector! Replaced an aging, BenQ W1070 1080p projector with the HT3550, and could not be happier. Fits the same as the W1070 in my slightly smaller room, and produces a brilliant sharp 4k image. Movies and 4k content is spectacular. HDR required a firmware update out of the box. (1.0.3 to 1.0.5) that resolved HDR coloration issues to my satisfaction. Gaming works very well. Was a little worried about lag going in with the listed (~50ms) lag, but found it to be perfectly acceptable for couch console stlye gaming. No noticable difference in play to that of a standard 4k tv. Tested 3D content on Blu-ray and it worked beautifully with plenty of light and a bright image. At this price and feature level I highly recommend it!

This projector was a direct upgrade from an HT2050, which I loved, and is my first 4K projector. The sharpness of the image and richness of color continue to blow me away every time I watch it. HDR10 support makes a huge difference in picture quality. The improved contrast, due to the inclusion of a dynamic iris, is an added bonus as well! Overall, this is a significant visual upgrade from the HT2050. The HT3550 is easy to setup and requires little or no color calibration out of the box. If your head is near the projector, you will notice some fan noise. This tends to disappear once audio kicks in. At the moment, this is the 4K projector to beat for under $1500. Even when compared to projectors double the price, this projector offers compelling competition.

For background I have owned the benq w1070 for 5 years or so. Which has performed wonderfully. I have had my eye on the 3550 for a little while. Having pre ordered the xbox series x I figured it was time to upgrade my dedicated theater room to take advantage of 4k standard next gen games. I already own an xbox one x and 10 or so 4k uhd physical movies. Now that I have mounted it properly to the ceiling to get the image up to size for my 120 inch screen I can give an opinion on its performance. The clarity is stunning. The picture attached to this post was taken from my couch with my phone. It doesnt truly convey the experience, but I think its a good example. Film grain is obvious, so I found that the best quality in terms of clarity was from digital films on uhd discs. Avengers Endgame looked amazing to the point that I think the image is superior to a movie theater. The factory settings on the projector are close to perfect. The brightness is excellent in my dedicated dark basement theater room on a 120 inch retractable screen. Some key facts to keep in mind. This model uses pixel shifting to create a true 4k image from a native 1080 dlp chip. Whatever technological trickery they developed here works, end of story. My guess is upgrading to a native 4k projector would could/would be an improvement, but honestly I cant see a difference and that upgrade is thousands of additional dollars. I have a nice Sony 4k tv in my living room and I personally feel you cant fully appreciate the benefits of 4k unless the screen is huge, now that I have tested that theory I am convinced. Also, a key consideration for me was 3d. Like my previous w1070, this model supports 3d, so I cant still watch my large library of 3d blu rays. If you have never seen 3d with active glasses on a dlp projector its an incredible experience that I highly recommend. One last note, there is apparently some lag on most of the 4k projectors for gaming. I am a grown up who still plays games, not a competitive gamer. I tried out several games in 4k on my xbox. No lag issues I was able to identify. I also had to order a new ceiling mount as the hole pattern for the 3550 was totally different from my previous projector, but that was expected. To summarize, for the money this projector punches way above its weight class. If you have the space to dedicate to a home theater this is a worthy investment. Its a no brainer upgrade over the benq w1070, which for me was the best value of any audio visual equipment I have ever purchased. I am super excited to get my next gen game system plugged into this bad boy.

I used to drool over the 4k projectors and think to myself that it will be forever before I am ready to spend enough money on one. I owned the HT2050 until the HDMI ports got toasted by a nearby lightning strike and loved it. I had looked at the newer models from Benq but was not impressed with certain things they took away from them or added to them. I stumbled upon the 3550 just as it was being released and my jaw hit the floor. I finally had time to get it hooked up on a 180 screen with 4K and it blew me away! I didnt want to go to bed last night or work today. Just wanted to lock myself in the media room. I dont think you can find a better projector for the price of this one. My only complaint thus far is that it seems a bit loud during quiet scenes, but I am sitting under it.
