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

Bought projector and have used it for viewing in home theater a couple hours a day on average. Now 9 months later white spots have appeared and the seller refers me back to manufacturer since it’s beyond thirty days. The seller does not back up the products they sell. Should have bought from A more customer focused seller. Lesson learned.

This projector is simply fantastic. The image, design and feature set (zoom, lens shift, no light border etc) make this guy a winner. 4K films are simply incredible, blacks are inky black thanks to its dynamic iris, and HDR support truly makes for an excellent viewing experience. Great value for the money. The only thing I dont like about this exceptional projector is the optical output is only stereo. Not sure what Benq was thinking when this decision was made. Its seems silly to design such a fantastic machine, then limit it to Stereo output via its toslink port. I had to purchase a sound extractor device to strip the 5.1 sound from HDMI, and then pipe the sound from the device to my surround system. This was an inconvenience, and unnecessary expense, when Benq could have simply incorporated 5.1 Surround out of the toslink port. Wishful thinking I know, but hopefully a future firmware release will turn on surround sound from the optical port. Hopefully it is a firmware limitation....albeit quite unlikely. That is the only fault I have with the projector. I hope this review helps anyone contemplating this projector.

Great projector at a nice price point. No complaints at all.

The projector had a stuck mirror. I want say that SCORE MIGHTY. Has great customer service. Had no problems with my return. Thanks for being a great seller.

I own a BenQ projector that I bought 6-7 years back which still works great. Decided to upgrade to a 4K projector and chose this. The picture quality was Amazing. It was a natural progression from 1080P to 4K - till it lasted. As some have observed, the projector stopped working after a few movies. Except for the Green power light blinking and turning on, the projector is basically dead. No sound (of the fan), no light. Hope BenQ finds the issue and fixes it so future customers dont have to go through this...

Its awesome i love it for my movie nights

This is my fourth projector in 10yrs. Recently had the Epson 5040UB and decided to go with Benqs HT3550 DLP 4K (1080 × 4), over Epsons new 5050UB claimed 4K which actually only displays 2k (1080 x 2) (read Epsons fine print). The HT3550 is also about half the price. The HT3550 is so much sharper than my old 5040UB, its like seeing 4k for the first time. Due to having light colored walls in my light controlled theater, I really dont see a noticeable difference in the claimed contrast between the two. This project is not advertised as a bright room projector and will not be suitable for that environment. With todays projectors in the sub $3000 range, theres a trade off of either having deep rich true theater like colors, or a super bright picture. I prefer I true to form picture in a light controlled room.

Projector is a great value for the money, however Im just now starting to see (6 or so weeks in from new) an occasional split screen like has been mentioned in forums regarding home theater and BenQ projectors. Hopefully this wont become a major problem like my last one did, but that one was a renewed projector so who knows what was fixed or not prior to sale. Would like to give 5 stars but just cant....

Using this in a room with no windows, picture is bright, colorful and was easy to install and set up.
