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

On paper, this is a great projector. Reviewed, it is a great projector. As others have stated, it hits all of the right notes. Im not sure I can say anything more than what has already been said. I really wanted to like this projector. The fan noise was a deal breaker for me. It is way too loud and distracts from the quiet scenes. Turn it to Eco and now a already struggling to be bright enough projector just becomes too dim.

I bought the ht3550 16 months ago. It has failed 4 times. Benq has sent me 3 of them and 1 was repaired. The DMD chip fails after 4 to 6 months. A white pixel will show up. Then before you know it , there are dozens. I returned the first one after 4 months because of big white spots. They sent a new one. 5 months later I sent it for repair. They sent a new one. 3 months later I sent it infor repair. Got a new one. Sent that in for repair and it was repaired. Customer service aint great so its a real pain. The last repair I asked for bulb replacement (4000 hours) and was told the bulb should last 20,000 hours. There is no way that it true. Its only 2000 lumens anyway. Turned out they were just out of stock on the bulbs. Thats a problem too. Customer service doesnt care about making things right so look at optoma or epson.

Dim bulb that flickers during bright scenes. HORRIBLE customer service: they disregard every issue I’ve consulted with them. The colors were completely messed up on the first one I received and the hdr didn’t work. BENQ technical support refused to help and I had to get Amazon involved to receive a replacement. Instead of saying our projectors have defects, they tell you that their projectors don’t have defects.

Disclaimer: This is my first projector but I am very impressed overall. I was at one time planning on shelling out close to 3k for the Epsom 5050 (which does look amazing) but then I realized I had planned my home theater room without a huge throw distance from projector to screen (just under 9 feet) and I was hoping to use a 110 screen. My fears that the Epsom might not quite have the throw ratio I needed led me to look at this BenQ and Im glad I did. This BenQ isnt what they call a short throw projector but it does have a more generous throw ratio than most other regular home cinema projectors. Im pleased to say that the picture is stunning and the price saving enabled me to invest in a better amp and speakers for the room. I bought a Panasonic 4K Blu-ray player (UB 420) and it looks stunning in both 4k and 3D. It will make you want to stock up on 3D movies. I have a dark dedicated home theater in a basement and I can imagine this could struggle in a room with natural light. They also say this isnt a great projector for gaming but I have hooked up my PS4 to it and had a great experience. To be fair, Im not an online gamer where I suppose the input lag could be detrimental. However, for local gaming (1 player campaign/story or multiplayer split-screen) I dont notice any lag at all, just a big beautiful image. It has a very nice backlit remote too. I have had a few moments where I have had some glitches from the 4K Blu Ray signal and had to restart the projector but that has been my only negative. This issue might be unique to my individual unit though. Overall, I love it and I know you will too if you have a dark room, especially for the price. Update: I have since had several problems, first with my original unit and then with a replacement. Now Benq arent answering support calls or responding to emails. I know we are in the midst of a pandemic but this still isnt good enough for such a big company. Ive lost all faith in the brand. Stay away!

Tips: Download the Firmware update. It will fix some of the color issues, mostly with HDR not looking right. Picture needed slight adjustment but was really close. If the HDR picture still doesnt look right after the Firmware update (too red or funny colors) turn off the HDR for that show you are watching. HDR did not work well for non-supported HDR programs, but did look good for programs with HDR. Maybe the Auto doesnt work perfect. Definitely worth the money. 150 screen that looks 4K amazing

I just received this projector yesterday and am incredibly disappointed in the whole user experience as well as all the bugs. For a $1500 projector I expected something way more functional than the Epson my housemates bought for $800. Something seems to be wrong with the HDR mode as sometimes the entire image looks like it has a green overlay on it (EDIT: I fixed this with a software update). Additionally, when HDR mode is on something inside the projector makes a horrible grinding/buzzing sound, like old computer sounds from 15 years ago. The green overlay isn’t always there and the buzzing sound isn’t as well, so there has to be some issue with it. Edit: here is a link to a video of the sound coming from the projector. https://youtu.be/LHJC_qN9Ils Does not play sound from my Sony Blu-Ray player for some reason even though my housemates projector has no problem. Input switching is incredibly slow as are changing some other settings. Sometimes I’ll switch back to my AppleTV 4K and the projector won’t even recognize the input, so I have to restart the projector (which takes five minutes) just to get the AppleTV to show up. I reached out to BenQ yesterday and am waiting to hear back so I can update this review. But if you’re stuck at home right now and are looking for a projector, don’t get this one because it’s not worth the hassle, even without the bugs it’s still a pain in the butt. EDIT: it has been almost a week and I have received no response from BenQ. The image quality is nice, but the whole experience so far has been way too frustrating for something I was so excited to get. Now I feel like a sucker for spending this much money on something that should have been way better. Why does it say “stream Netflix and Prime”? There is no smart TV interface, it’s just saying you can plug in a streaming device through the input. So with that statement it’s clear every statement they make about this projector is just meaningless marketing hype. I expected so much better from BenQ.

Okay so I currently live in a dorm so I cant utilize this projector to its fullest but soon Ill have my own theatre room. Anyway heres a short video of the projector in action. Just on my plain wall which is white paint. The blacks are actually amazing. I cant imagine what this will look like on a silver or black screen. I cant stress how good HDR looks! I own a QLED TV and wow this is comparable with the extra movie emersion! As you can hear the sound is not bad if youre on a budget and cant buy a surround sound system yet. No worries this can still deliver quality sound. No changes in settings. I just plugged it in and turned it on. Only adjustments needed were the focus ring. I also liked the remote. Especially the satisfying clicking feel and sound from pressing the buttons. Overall I have poor conditions for a projector setup right now yet this projector performs brilliantly. UPDATE!! 2AUG19: the blacks produced are so good I highly recommend a white or grey screen otherwise you lose the vivid colors. I only watch in dark so its pointless to have a black screen. UPDATE!! 10AUG19: got my new silver ticket white matte screen. This paired with the projector makes me feel like Im in the movie theater.

I was hopeful that passage of time and technology improvements would make this a better projector than my unconverting 2k to 4k. ....not so much. :-(

I purchased the BenQ HT3550 4K Home Theater Projector for this Christmas 2019, so far everything seems great in SDR format but when I use HDR the picture is a dark blue, everything is a shade of blue, I tried to make changes during but it doesn’t seem to change it much, setting different lamp brightness, picture modes and using the brightness/contrast as well as changing the Cinema settings pretty much have no effect, it remains blue… 12/27/2019 Currently I am awaiting a response from BenQ, and depending on the answer I will revise my rating, I wish I could give this 5 stars, I owned a previous BenQ projector (1080p) and it was fantastic! 12/29/2019 Update: Flashed to the newest firmware and reset all settings, I am happy to say the blue HDR has been corrected, and the picture is wonderful, but when disabling the pixel motion enhancer the fan is extremely loud with what sounds like an internal vibration noise. I will be returning this projector for another like unit in hopes that it was a defect or damaged in shipping...

Benq ht3550 only lasted less than a year stopped working. Customer service from manufacturer is terrible, hard to reach. Do yourself a favor and purchase another brand.
