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

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!

My friend and I have an expression when we see or hear something spectacular. Its, Hold it, Hold it, Hold it! Folks, this is about one of the best kept secrets in home theater or home entertainment! I dont think there are any words in the dictionary to express the picture quality and price of this unit! People, tbe Benq ht3550 is a True 4K unit. It does not Pixel Shift like other projectors are built to do to trick the eyes for 4k imaging. Benq calibrates this unit at the factory, colors and all to ISF (Imaging and Science Foundation) and cinematic standards the way the producers meant them to be seen. This unit ROCKS! and even has a longer lasting bulb than other units. It is about 1.30% larger in size of the Benq w1070. What sold me on the unit was the purchase of the Benq ht8050 I installed in my parents home in Colorado. We were watching the 4K version of The Lion King in a 120 screen and I fell out of my chair when I saw the immense clarity of the ht8050 that does not even have Dynamic Range. Its a huge unit and required blocking between the rafters to center it. The ht3550 I have is light in comparison and has Dynamic Range! Excellant, excellent unit and I highly recommend that people purchase this unit!!

The fan was a major issue for me. Way to loud. Went with the HT5550 in the end and fan was extremely quiet. Better choice for sure

This projector worked well in the small space I had and is bright given the fairly dark room. I think even in a bright room the picture would be fine. I updated the firmware and changed the settings to enable hdmi 1 to ARC from my sound bar. Excellent picture quality in 4K!

Look, its a nice PJ. Its quiet enough and resolution is great. It is picky about the strength of your HDMI signal - there are plenty of older HDMI receivers that will not have enough signal to light it without (at least) tweaking the settings in the built in HDMI Equalizer. Even when you do, it is inconsistent and fussy with resolution. If you wire it straight from the source (Apple TV, PS4) these issues do not present. I am upgrading from an 8 year old 720p DLP unit, and have never been able to see the rainbow effect with it - on this one, I can see it in the whites every time, without fail. Also, this thing is bright. On its least powerful settings, I still had to mount an ND filter to the front to get it dark enough in my completely light-controlled theater. (No, you cant adjust brightness and fix this, brightness is a component of the picture adjustment, not the lamp output.) While the color rendering is truly terrific and remarkably-tweakable, the sharpness really does leave something to be desired. While there are work arounds for the other issues I have with this PJ, there is no fix for underperforming glass, and this is ultimately why it was returned. What can I say, its mounted dead level, flat and true and it is discernibly soft at the edges of the screen. My screen width at 16:9 is 87, it starts to lose focus about 13 from either side. The lens just isnt up to it. You can see it in programming and it is very obvious using the (internally generated) alignment grid feature. I really, truly wanted this thing to work out and Ive tried accommodating it every which way - lots of people obviously love this PJ - in my experience... its just not cutting it. For similar money, the Epson is hands down a superior product in every possible way.

This is my first time purchasing a projector, but I have experience with buying other high-res TVs and computer monitors in the past. I think for the price point ($1499.99 at the time of writing this review), this projector is well worth the money. For the past week, I have been testing out the capabilities of the projector on 4k movies and games (native and streamed). I thought that the colors on the unit out of the box were superb, similar to what you would find on an IPS computer monitor that has been properly calibrated. BenQ even includes a color calibration report in the box. The sound coming from the 2 5W speakers on the projector is respectable for what they are. They wont get very loud but the quality is definitely good enough for a small outdoor venue or room. I would recommend separate speakers to pair with this projector overall, though. In comparison to the ViewSonic PX-747 4K projector ($899 at the time of writing this), which I initially purchased along with this projector to see which I preferred, you will definitely benefit a lot from sticking with the BenQ. While the sharpness of the two projectors for 1080p and 4K content does not differ vastly, the contrast on the BenQ makes a world of difference. When watching darker scenes in Stranger Things and playing darker levels in Gears of War 4 on Xbox One S it was very hard to make out the finer details and certain objects in frame on the ViewSonic. I tried to adjust the brightness and contrast to fix this but colors ended up just looking too washed out. On the BenQ, however, I immediately noticed an improvement in contrast and HDR quality and had no issues with these darker scenarios. Moreover, the BenQ was much faster when powering on or switching inputs, which doesnt sound like a huge factor but definitely helps if you use it a lot. The $600 jump between projectors, if you have the money for it, is definitely worth it if you want to have a projector that youll be happy with for long term. I will say that if you are expecting this projector to be movie theater quality then you may be slightly disappointed, however. The overall dynamic range is still not as good as a 4K TV at a similar price point, the projector is not bright enough for a well lit room, and the sharpness could be a little better. For something with improvements to those qualities, youll have to upgrade even further to a better BenQ, Epson, Sony, etc projector that has native 4K. I think for most people youd be better off spending that money on a good projector screen, projector ceiling mount, speakers, AV receiver, HDMI 2.0 HDCP 2.2 cables, 4K Bluray movies, etc to accompany this projector. Youll get rapidly diminishing returns upgrading to more expensive projectors, while this projector definitely hits the sweet spot in value (at its very portable weighing only 9 lbs). Id definitely recommend it!

I feel its important to note that one cannot fully disable motion smoothing on this device. Even with the setting changed to off there is some smoothing. Its especially bad with 2d animated films/TV, or anime where some elements on screen update at a framerate less than the video framerate. it looks awful. my suspicion is that device uses motion smoothing to add frames when there is a mismatch between video framerate and display refresh rate, instead of something like the more common 3:2 pulldown. in my opinion this was a bad move, as the artifacts from motion smoothing are far more noticeable than a flicker from simple frame pulldown. It can be mitigated, or fully eliminated, by setting the projector refresh rate to be equal to the video framerate, but this is not possible on many devices (e.g. chromecast), and it takes a good ~5 seconds or so for the projector to switch between refresh rates. additionally some video framerates may simply not be supported by the projector.

I was tossing the idea of an 88” TV vs. 120” projector. Sure am glad I went with 120” Benq projector. I added a Sony home theatre surround system and made our room the complete experience. Wow, sports and movies are amazing!

Using for an outside projection screen on rear deck. Any ambient daylight really makes the projector unusable in this application. Total darkness required.

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.
