This BenQ TK800 review has been a long time in the making. I got a look at a pre-production unit in April and published a respectable “First Look” review and a comparison between the TK800 and their HT2550 from the standpoint of which you should purchase based on your room and viewing habits. We finally received at TK800 a few weeks ago. I watched it a bit, took a few “out of the box” photos of picture quality, and sent it off to be calibrated.
Since then, I’ve put dozens of hours in watching the BenQ, replaying scenes, etc.
Short story: Want 4K capabilities, a very sharp image, a healthy amount of brightness for rooms with more than minimal ambient light, and a rock bottom price for all of the above? The TK800 very likely will fit your needs. There are a few competitors out there. We'll help you figure out if this BenQ projector is the best choice for your setup.
Editor's note: I was hoping to get this review published before leaving on an Alaska cruise. That didn't quite happen so I'm publishing what I can from the ship, on the first full day of cruise'n.
Regarding performance, here's a very short version. The TK800 came in just a bit short of the 3000 lumen claim. Eric came up with an eco (low lamp) best calibration with about 1000 lumens, and a 4K HDR mode was created with more emphasis on brightness, and that came in at 1933 lumens. Impressive, considering the ending color results. More when the page is up. Sharpness is also on that page. Suffice to say that the TK800 is a very typical 4K UHD projector - very sharp on 4K content. If you aren't siting really close you probably can' tell the difference between the BenQ and an entry level true 4K projector. -art
