BenQ TK800 4K UHD Home Theater Projector with HDR and HLG | 3000 Lumens for Ambient Lighting | 92% Rec. 709 for Accurate Colors | Keystone for Easy Setup

Comment

Initial impressions: Fairly straight forward to setup, the picture quality is amazing compared to our old 1080p Sony TV; I’m yet to set it up permanently on the ceiling. The good: - crisp clear 4K image with full HDMI 2.0 - very bright picture even in well lit rooms - loud audio from the projector - light compared to similar products The bad: - No horizontal keystone adjustment or lens shift - HDR support is limited - no SPDIF output for digital audio

Projector was easy to mount. Locating it on the ceiling was a breeze given its light weight. The picture looks real good and bright in a dim but not completely dark room. The reason I gave this Benq three stars is because there is an annoying whining sound coming from it during operation. I have an Optoma and a couple of Viewsonics in the house and I can certainly hear their respective fans as Im usually sitting under them when watching a movie. This doesnt sound like any projector or computer fan sound. Definitely louder and with a whine. May have to return this and try something else. Im not complaining, mind you. The picture really is good compared to my 1080. Might have just gotten a lemon. Good luck.

After reading reviews and looking at product specs for 2 weeks we finally decided on purchasing the BenQ HT2550. This projector is replacing an Epson Home Cinema 3020 which is about 5 years old. This is our 3rd projector since 2001. Each one was better and less expensive than the previous one. After reading everything we could find we were going to get the BenQ TK800. Then we found out the main differences between the two were the lumens and the DLP color wheel. The BenQ 2550 has a RGBRGB color wheel and 2200 lumens while the BenQ TK800 uses a RGBW color wheel and 3000 lumens. The lumens were not an issue since our old projector had 2300 lumens and it had plenty of brightness. The color wheel was more of a deciding factor since we have owned 2 DLP tvs in the past and "rainbows" were a concern. The RGBRGB color wheel is supposed to lessen the rainbow effect. While setting up a Roku Ultra we did see some rainbows while in some extremely contrasted setup screens. The first movie we watched was the 4k version of Deadpool 2 and we did not see any rainbows. We then checked out several scenes from Black Panther and Passengers and the picture looked awesome. Blu-ray dvds also look better . We decided to get the BenQ HT2550 over the BenQ TK800 because of the color wheel and the lumens were not an issue because our home theater is totally dark and 2200 lumens is enough. We watched Deadpool 2 before making any adjustments to the projector and it looked great. This projector is quieter than the one it replaced. You dont hear it while watching movies. you can hear the fan while the room is quiet but its not that loud. If youre looking for an affordable 4K projector you cant go wrong with the BenQ HTR2550. It also came with a $100 Amazon gift card which brought the price down to $1399.

Highlights: #1 Great picture. Compared to my 5yr old HD Epson, HD was much sharper, blacker levels and rich color saturation - no adjustments. The 4K picture is phenomenal (see JPEG still below of 4K Dunkirk movie). #2 Skin colors are accurate and color levels are vibrant. #3 Small compared to my old behemoth HD Epson and is light weight Lowlights: A bit noisier than my old Epson but no big deal once the movie is on Tips: 1. Use the Benq installation calculator (at least look at it) its extremely helpful to orient yourself 2. Note the lens is not in the center of the unit (this may save you from a left of center picture after all that installation to the box center) Summary: Great picture. You wont be disappointed if youre upgrading from older HD projector and want to see better HD and 4K. Installation was disappointing for me but I suppose thats a one time headache so plan ahead.

While this isnt a native 4K projector, it still looks really good and better than any regular 1080p projector Ive seen; especially for the price. It took me a while to get the colors looking good but after I did it looked very good. I was planning on getting the UHD60 but Im glad I went with this one instead. My only complaint would be the border light which is a dim black light that extends about 6 inches around each edge of my 120 inch screen. After a while I got used to it and didnt even realize it was there anymore. It would be nice if there was some way to get rid of it.

The Picture Quality is good but the halo effect on the screen is not comfortable for me unless you dont have black masked screen so I could not enlarge the screen size as big as other projectors.

This looks far better than I could have hoped for. HDR is absolutely stunning. I was looking around for Black Friday deals on 4k tvs but they are really expensive and the bigger they get the more people have problems with the LCD panels. I was already using a 120" screen with an Optoma HD142x so anything smaller than 100" was going to feel like a big step down, even with the extra brightness and pixels. The colors out of the box are pretty tame and muted. Google search calibration settings for this projector and youll boost the gain on some of the colors and it makes a big difference. It looks like the demos you see in the store of HDR in action. Once you get the settings right and have everything hooked up correctly go to Youtube and search for HDR and there will be a lot of movies in 4k and 8k to watch in HDR. Amazon and a few other streaming services have some movies in HDR. 4k is cool but the colors with HDR are unbeatable. The price is amazing. Considering a 75" OLED TV is over $2,000 this is such a steal. Even when the bulb goes out in 18 months it will still end up being far cheaper than a tv. Benq you are my lover.

I suspect there are a fair amount of BenQ W1070 projector owners out there who were/are excited about the arrival of the 2 BenQ models that do 4k AND 3D....but are confused as to which one to get. Certainly, the TK800s 3000 lumen spec is exciting, but then theres all the puff and fluff out there (and in the promotional materials) about the color gamut on the HT2550 being so much better. At one point in my pre-purchase research, Id read on a respected site where the reviewer said that the HT2550 was the true successor to the W1070 in terms of color and quality. Thankfully, I later found on a projector enthusiast site a comparison for all 3 projectors actual lumen output when in various color modes. That was the decision-point, as it seemed clear that the HT2550 actually under-performed the W1070 most of the time (even though it has a higher rated lumen output). I could not be happier with the decision. I use a grey screen, and if anything, Id say that the colors are easier to adjust well on the TK800 (less need to tweak), out of the box. The extra lumen output is definitely noticeable, and just makes watching more fun, no matter the mode. (Note: With the W1070, I always replaced the bulb before 400hours, because 3D gets less watchable at that point.) To see this projector in 4k in 120" (my screen size) is to finally REALLY SEE 4k. I can say now (and may sound like an elitist to some), you cant really appreciate a true native 4k production unless youve got it huge; even a 65" display doesnt really tell the true story. The BenQ does very well at reproduction. Some notable caveats with the TK800: There is indeed light-splash which the W1070 did not have a problem with. I can live with it, considering the value. A very important consideration: The throw distance is much tighter than the W1070. The older projector had a much more adaptable zoom, and you could have the projector closer to your screen. With the TK800, I had to alter my mount to set the projector 6" or a little more closer to the wall (farther away from the screen) in order to fill 120" edge-to-edge. Thankfully, I had that flexibility in my room and where/how I had the mount installed. Fan-noise is a little higher than the W1070, and the casing feels a little less robust, but both are negligible. If youre like me and using a 2k-compatible AVR, but sending 4k direct from Ultra-HD BD to TV or Projector, I would highly recommend that you install a separate cable for 2k and for 4k into the projector. (In my case, I used the excellent Measy wireless 2k/3D HDMI dongle system for the 2k run.) Even if you have a 4k AVR, if you have 2 BD players and you really love 3D, I would recommend the dual-line system. Heres why: On the TK800s primary HDMI (4k) input, you have to manually set the projector into the 3D mode. This projector is not super fast at locking onto signals, especially when doing this change-up, so 7x out of 10, your BD player is going to moan that youre not running a compatible 3D display, due to timing issues with the sync. However, I was super-pleased to find that when using a 2k line into the TK800s second HDMI input, the projector acts just like the W1070, and auto-switches to 3D and back! Last note: If youre sensitive to DLP rainbows, Id say that 4k mode is likely to trigger that more often, especially in high-contrast, low-color scenes. Since its shifting/flashing the image 4x in order to assemble the 4k image, theres now twice as much flashing and stuff where your brain has to piece the picture together. In the past with the W1070 and 2D mode, Id occasionally see them. I DO see rainbows more frequently on the TK800 when in 4k mode (although in 2k mode, I actually dont recall having seen the effect yet, in about a month of use). To me, its the price to pay to have a great projection system for a very reasonable price, and not having had to sacrifice all future generations of my family in order to pay for it.

We bought this BenQ 4K projector around Thanksgiving holidays. It was working fine and the video colors and brightness were good in 4K initially. However, after 2 months, the video brightness becoming dull and colors becoming more of a black & white shade all of a sudden. After some time, it goes back again to the original brightness and colors. It is really disappointing and disheartening to see such a bad quality image and performance within 2 months and spending almost $1500 to purchase this projector. BenQ and Amazon should respond and address this issue quickly, if they are really keen on the customer service and providing good quality products to your customers

Felt nice hanging it up. My hopes may have been too high. 4K sucks on this. My 1080p (500$) projector was better with 1080p picture. On top of that, the projector won’t stay on longer than 1.5 minutes before I get an all black screen. If this wasn’t a defective unit, holy hell. Benq needs to get their crap in a pile. I’m sending it back and going with Epson. Box was in good shape, so if anything the defect or horrible product is all on Benq. Two thumbs down. Update: Probably was a defect. Got the BenQ THX and I don’t see myself buying anew projector for at least a decade. I’m floored. And I’m no expert, but it’s better than any projector I’ve seen outside imax or similar theaters. I have not seen the exotics or lcd projectors yet.
