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

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 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.

BENQ delivers as expected. I bought this to replace my 12 year old Epson Cinema HD projector after the internal board went bad (known issue). Mounting this can be a big pain because the BENQ has hump on it where as most projects are flat where the mounting brackets go. I was able to use my 12 year old mounting bracket by some adjustments. First I added some foam on hump and got bigger screws (M4) to make the bracket connection. The foam was used to prevent scratches and dents, and to get the bracket and screw in. The other two screws on the flat areas were simple to get in with no modifications needed. Also I preferred to use my old bracket as it was measured for my 120inch screen. The only other work was running a 4K HDMI cable around 30 Feet as there was no 4K 12 years ago. Also had to get a new receiver and a few more cables for other media devices. Now the setup once powered on was pain. BENQ should of made this simple but one has to play with this setting plus the remote etc. Finally after an hour of moving the project in X direction and playing with remote plus the lens on the project I got everything adjusted to my 120 inch screen. Since I am not using this for gaming I cannot rate that.

I would say if you get a good unit your golden if you dont make sure you can exchange it for a new one. Benq has great customer support and sent me out a new unit after my first one had issues. It is rather loud so youll probably want to set the bulb to eco mode. That aside for the money its hard to beat in the 4k realm. Big take away for me was it has more detail than the epson. Epson has better colors but its not great for 4k. Your better off saving some money and getting a nice 1080p projector over the 4k epsons. But if your rooms dark or a dedicated theater room this projector cant be beat for the price in the fake 4k market.

The projection is great but it is not user friendly. Adjusting this projector is more difficult than it should be. The Google stick that it comes with doesn’t have Netflix.

Its great for the the price.

Looks great projecting onto our 120 silver screen

I’m coming from an Epson Home Cinema 3500. Had it for 4-5 years and ran into the “auto iris error” which seems to be somewhat common with some Epson models. I am looking to get it repaired, however I was hoping to take the opportunity to try out a different brand while I sent my Epson in for repair. After a lot of research and watching several video reviews, I settled on the Benq HT3550. This true 4K projector looked legit and everybody raved about it. I was very excited to give it a try. I’ve never experienced light leakage from a projector before but almost everybody talked about how it was an issue in the previous model, but Benq got it right with this one. I have to tell you, in my opinion this is a pretty big deal. Call me OCD if you want but to me there’s no reason for any projector to be putting out such a distracting light border. I included a picture but please know the image cannot capture the prevalence of the border. In person, it is extremely noticeable. I marked how far out the border goes with the yellow line in the picture. You can see it better without the image on the screen, but it looks like I simply need to keystone the image and zoom in to fit the screen, right? That’s why I included the image of the picture on the screen so that you could see the image fills the screen, keystone is great, but you still have the light leakage. To be fair, my wife says that it doesn’t bother her and when you are watching something on the screen, you don’t really notice the leakage as much. However, I do notice it and it really bothers me. Have a mentioned in the review yet that I’m a little bothered by this, ha! Sorry, I just can’t explain how people are overlooking this issue. The best explanation I have read is that all DLP projectors have a little light leakage and people sort of chalk it up to being something you deal with. Bottom line is it is a superb projector and image quality for the price...IF (and it’s a big IF) you are OK with a 6 to 8 inch light border around your screen. I’m not so it’s going back. It’s really unfortunate because I was really excited about the potential of this device.

Im very pleased. I watched a few video reviews before purchasing this projector and I like it even better than the reviewers did. To my eyes the lamp brightness is more than adequate for a dark room even when using the wide color gamut. If youre a gamer, the input lag is only going to be a problem if youre playing competitive multiplayer or if you play a lot of twitchy reflex games where every millisecond counts. I was playing GTA5 (by myself) last night and I didnt notice the lag while playing. 4k hdr movies with wide color gamut turned on are beautiful, I watched The Revenant recently and all those outdoor scenes really popped.

This review is for the “cinematic colors” model HT3550 This projector perfectly met my expectations (though it didn’t exceed them—IMHO that’s 4 stars) The picture quality is really very good for a projector at this price point. 4K projected pixels and color wheels designed for accuracy means you get a really good looking picture right out of the box. The brightness is fair but things definitely look best in a mostly dark room. It’s a top level consumer projector rather than an entry level prosumer projector: build quality is fine but underwhelming. Not the most light tight enclosure and the fan noise while acceptable is not whisper quiet. My single biggest disappointment, while not unexpected at this price point, is the chromatic aberration of the lens. High contrast edges (e.g. the white text when you pause a Netflix movie) have a blue/yellow shift, but frankly not noticeable at normal viewing distances. Was pleased to find replacement bulb prices are reasonable (in the neighborhood of $100) and as a home cinema solution I think it’s going to meet my needs really well for several years to come. If you’re looking at this review you probably already know this, but this is not for gaming or daytime sports. It’s best suited to a movie theater like environment and content.
