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

Dead on arrival, power on to immediate red flashing light with no picture at all. I would avoid this at all costs! DO NOT BUY!!!!!!

I have the projector mounted on the ceiling, pretty close to seating area. The projector is loud and is distracting. The picture seems pixelated. Another user suggests to turn off HDR in source and in the projector for better picture quality. Will update once I get a chance to do that. I wouldn’t recommend getting this projector.

I have over 2400 hours on this unit and it’s been great. I only had issues once when using for 12 ish hours continually. I think it overheated and malfunctioned for an hour or so. The reason I am writing this review is because I just got an Xbox Series X and had the following problem: the main Xbox menu worked fine, but when I went to play Amy game or open any video streaming app, I got a black screen. Solution : press the HDR button on remote and turn from auto to off. This allows me to use the Xbox. Before making this change, changing the Xbox output resolution to 4k would cause all picture to go away ( even the main menu). With HDR turned off, I can change output to 4k and it works. The problem seems to be that I need to turn HDR off every time I use it now which is a pain. But it’s a fix.

Picture quality is great and setup is easy.

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

four stars cuz i have a flicker that happens on the right side of the screen for ceiling mount. i contacted BenQ and they were very accommodating with the process for repair or replace. They told me id be sending my projector in they will try and repair it or just send me a new one.

I don’t know exactly how I feel about this projector because HDR was one of the main reasons why I bought this projector but it doesn’t seem to work properly. The projector is good and the picture looks decent but once you apply the HDR feature it’ll disappoint you!!! The colors show either very bad or your image will show in green and black. I use HDR 10 supported products with a 2.0b HDMI and it still shows up horrible with HDR on. 4K looks awesome especially at 100” though I will say that! Other then the HDR not working properly, this projector is very good. One thing I would say before I wrap up my thoughts, this thing will heat up your entire room! The fans blow out really hot air so during the summertime make sure you have your AC running when you decide to watch something on this.

Sharp high-def images, very pleasing to the eye.

I decided to upgrade from my 5yr old W1070 which has never let me down. All I can say is WOW, the HT3550 is a day and night difference. Im not sure whats to come in 5 more years but Im confident BenQ will be on the top of my upgrade list...again. (the pics are in a fully lit room without any projector adjustments)

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.
