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

Just a thing of beauty. Fantastic picture that keeps blowing me away.

This is my first projector and after looking at all of the different options, I figured this was the one to go with. Its been said that this projector resolved lot of the first generation projector problems so not having to deal with some of those quirks is always a positive. In any case, this projector was MUCH better than I had expected. Im just projecting on a wall and it looked so good that Im debating to whether to even a buy screen for it or not! Eventually ill get the screen but its not by any means an urgent need for me. I honestly cant tell whether im watching a TV or projector. Of course the room does need to be dark (some light is still acceptable) but if you have good amount of ambient light then the picture will look washed out. Things i dont like: 1) Optical output is only outputting stereo sound. Not sure WTF BenQ was thinking here. I ended up buying a new receiver due to this. This was major let down for me and almost wanted to return this projector. But my old receiver was in need of update anyways so decided to fork the extra money for a new receiver. 2) Fan noise (when I had it on a table this was a bit loud but ever since mounting it on a wall, Ive noticed that its quieter than before). 3) Mounting - For some stupid reason, BenQ decided to not have a flat surface for the mount side so one of the screws is right next to the raised body. You can probably see it in the pics. In the end it still worked fine but for a company whos in this business for a while would have given some thought about this and made sure that the mounting side is completely flat. I used the Mount-It mount as it allowed for extension to drop the projector height. Things I LOVE: 1) Picture quality - Hands down just amazing out of the box and Ive only just watched 1080p content so far! Planning to connect 4k firestick this weekend to get an idea of how great this projector really is. 2) Has USB power port (2.5A at that) so that I can just power the firestick off that port. Works perfectly! I really havent played around with the different settings on the projector and frankly im afraid to just because its puts out damn good image right now. Make sure to measure the distance from the lens to the wall and also the height of the projector. I think BenQ has a good calculator for this but again difficult to use. However, the best way is to just use a ladder and put the projector on it to see how the image would look. I just zoomed out the image completely and made sure that I was satisfied with the minimum image size it projected. After that I just found a good mounting spot for the projector mount between 1 to 2 feet after that spot so that I can then zoom in to get image size I wanted on the wall. Id say go for it if youre debating to whether to get this as your first projector or not. I dont think Id ever consider buying large TVs if a projector in that setting could also work.

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.

So we purchased this and got a dead pixel a few months later. We sent it back on RMA and got it back a couple weeks later. It worked for about a week and then a different pixel went dead. We tried to just love with it, but then a 3rd dead pixel. We just sent it back off today. The Epson we had never had an issue for 5 years, this has already been repairs twice and still getting dead pixels. I was very hopeful because of the good review, but if you have to send it in every 3-4 months, it really isnt a good deal. I hope they give us back a good one.

Great projector. Great audio speakers as well

Beautiful picture but very dim. Accurate color is clearly the focus here. Another great projector from the fine folks at BenQ. Nice 3D option and works well in a very dark room. Keep in mind that 3D makes the image even darker than normal when using shutter glasses. For you gamers out there looking at this....don’t! Look elsewhere. Honestly, the lag isn’t just noticeable, it is awful. Look into an actual gaming projector from Optoma or Epson. BenQ does have gaming projector options also.

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

I was thinking for a while about what would happen if my one LG 4k 3D 65 TV finally went out. You cannot buy new 3D TVs anymore. And I have lots of 3D blurays. So, I finally decided to replace my Panasonic PT-AE2000U projector in dedicated theater room with this BenQ. I did not have high hopes for this projector, given the price. BTW, the Panasonic projector is still a great 1080p non-3D projector, and I highly recommend it if full HD is sufficient for you. I needed the 3D functionality, and the 4k was a bonus. Please note this is not native 4k, but 4k pixel shifting. But the picture still looks amazing! I also hesitated buying a projector that used DLP active shutter glasses, as the LG TV uses passive 3D glasses. I remember in their early days the active shutter had a lot of strobing. Seems like thats all been fixed now. And you get a lot more color coming through with the DLP active shutter glasses, which I did not realize. I bought a 4-pack of the Boblov glasses, which are fabulous, and very reasonably priced. You can find them here: https://www.amazon.com/dp/B08C9SWQKM?psc=1&ref=ppx_yo2ov_dt_b_product_details I did not give this a full 5 stars because its missing some legacy inputs and regular sound output jack, I would have liked to have, as well as the horizontal lens shift mentioned in a minute. Currently the Android apps, such as YouTube, only use the projector speakers. Which, to be fair, sound quite good. I had just already wired a sound output cable above the ceiling for the old projector. Perhaps there is some converter i can buy. And there is no horizontal lens shift, which would have made mounting this pj a WHOLE lot easier. The Panasonic had both vertical and horizontal lens shift, with the pj lense in the middle. This one only has vertical shift with the pj lense near to one end. Thankfully, the mount I have installed in the ceiling has super adjustable mounting arms, so I was able to shift the whole pj to the left on the ceiling mount. Adjusting everything took a few hours, though. My biggest concerns before receiving this projector was ability to use the already installed ceiling mount and possible issues with the video source, a Zappiti mini 4k HDR player. The player worked perfectly with this projector. So, overall I very highly recommend this projector, its super bright and has an awesome 4k picture. The 3d looks very good. Some complained about the included app dongle but I had no issues. Netflix is not available with this dongle (maybe a licensing issue?), but there are 2 HDMI ports, if you wish to use a Roku stick or similar instead.

In 7 months ownership I haven’t had any HDR due to it changing white colors to caution yellow, then about 2 months ago an area in bottom left quadrant got some dead pixels (solid white). The part that final pushed a review is today when it wouldn’t turn on at all! Green lights come on, but no lamp or fans follow. Seems to be a semi common issue with them. I always had it plugged into either a Monster or APC surge protector, and it projects on a 110” silver ticket 4K screen with all appropriate cables to fully enjoy this highly recommended projector. Part 2! Big piece of you know what!!! PERIOD!!! NO QUESTION ASKED!!! So the company did in fact replace the first hunk of junk, and the second just failed too. It has had burnt out pixels almost since the day I got the replacement, and today 06/07/22 I turn it on got zero screen, unplugged it, and the screen is there with about 70 decibel burnt out cooling fan freaking out. COMPLETE WASTE OF MONEY!!!!!!! I could if bought a Samsung or LG 75 inch 4K for the price this thing set me back, and I wouldn’t of had to warranty one, and have dead second one. Things work great for a few months then practically self destruct. So now I have a 110” wall mount screen, 120” portable screen, wall/ceiling mount, and mobile adjustable stand that don’t do me now good for anything. Glad I bought a 65” LG C1 Black Friday 2021 for the bedroom it’s better gift games anyways.

Amazing picture. Quality is amazing, sound from the fans are very low to unnoticeable. As they clearly state, mounting options are quite slim; especially horizontally. But if you are buying and using a 4k projector, you should know there is some difficulty getting the perfect mount positions. Resolution is so good I constantly notice how cheap my screen is..... =O
