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 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.

(The good) incredible sharp, accurate color picture. It looks amazing. I also did not notice any rainbows. Very easy on the eyes even with all the lights off. Not loud at all. (The bad) it lacks brightness. You must have black out curtains or better yet a true theater room or only use at night. This thing does-not like light at all. It can been seen during the day but washes out so bad. I compared this with the epson 3800. It was a close decision as its a sharp nice sharp picture with amazing colors. In the end I chose the epson 3800 since the contrast was amazing and the colors would pop. I could even use it during the day no problem. Wish I could just own both but the wife said no ha ha.

Major set back is 3D. Yes it supports 3D but if you have ripped all your blue Ray to USB drive and have it in half SBS, you cant play it using media reader as the aspect ratio cannot be adjusted. If you have roku and use roku media reader, the projector wont detect 3D content and the button will be grayed out and no way to turn it on. If you try from remote - direct 3D, it will switch back to 2D and its a big no go. Benq cheap projectors allow you to use 3D manually but this one work. Have to return as its no go for me. Will look for laser projector at this price point.

Good picture. Some cooling fan noise. But the biggest flaw is the lens cover. Like the previous models, BenQ tethers a piece of plastic that you can use to cover the lens manually. This creates a problem: you have to be extremely careful not to change the position of the machine if it is hung from the ceiling. I wish BenQ could install a simple mechanism that allows the user to use remote control to cover the lens after done watching. Update: The auto keystone is a disaster. Even if you disable it, it is somehow still on, fighting with my manual adjustment. One star now.

Al principio pense que el contraste seria muy pobre como para cambiar mi actual epson 2150, wow, la verdad, quede muy sorprendido lo bien que se ven las escenas oscuras y de hecho la luz en el telon fuera de la imagen ni se percibe, que es algo que te puede distraer, por supuesto la clave esta en evitar la luz en la sala.

What I did like it did arrive on time. what I didnt like is that the product arrived with the wrong power cord. the cord was very nasty and dirty. what I didnt like was that the projector itself had loose parts in the inside lot of rattling going on in the inside when I picked the projector up wow totally dissatisfied. I did not power the unit up because I was afraid that the cord might short it out due to the damage Incorrect Power cord.

I used to drool over the 4k projectors and think to myself that it will be forever before I am ready to spend enough money on one. I owned the HT2050 until the HDMI ports got toasted by a nearby lightning strike and loved it. I had looked at the newer models from Benq but was not impressed with certain things they took away from them or added to them. I stumbled upon the 3550 just as it was being released and my jaw hit the floor. I finally had time to get it hooked up on a 180 screen with 4K and it blew me away! I didnt want to go to bed last night or work today. Just wanted to lock myself in the media room. I dont think you can find a better projector for the price of this one. My only complaint thus far is that it seems a bit loud during quiet scenes, but I am sitting under it.

I couldn’t wait for this baby to arrive from the Amazon Warehouse. It came a day early to my jubilee, and was nicely packaged in its original box. I was upgrading from my trusty old Viewsonic projector for outdoor movie night. There are a ton of reviews with specs and such, so I’ll just give you a layman’s version. The picture was simply astounding; both animation (Raya) and live movies. Granted, I’m coming from a 1080i, but the clarity of the image on my 4K JWSIT big screen (135’), blew me away. It exceeded my expectations. I drooled for the first three hours of viewing. The setup was easy, as well as slight adjustments to my viewing liking. The fan was never even noticeable. And the speakers were pleasantly adequate. My last projector sounded strained as I elevated the volume, but the ht3550 gave off an enjoyable, full sounding soundtrack. No sound glare as I increased the volume. I set this up with my son’s ps5 to take advantage of the 4K blu ray. Like watching movies outside for the first time. This is what I’ve been missing? I’d probably be crying if I wasn’t so elated by the upgrade. Gaming was just as amazing to watch. I noticed no lag, but we only played one person play. He did hop on fortnite with a couple of friends for an hour or so, but he had no issues that I could see. The ht3550 is truly a topnotch projector. I look forward to making it my own!

Pros Good picture quality and contrast. Good value at this price point. Cons Only for dark room experience even small bulbs can cause corners to brush and colours go fade. Quite bulky hence need professional service to do the mounting. Speakers are functional dint particularly like it. Would recommend only for those who wants to make serious home theatre setup in a dedicated dark room.

It even plays my older 1080p 3D movies w/ 3D glasses. Couldnt be happier :)
