Brightness Uniformity. The TK700 projecting a 100-inch diagonal image resulted in measured brightness uniformity of 75% while in wide angle zoom, and 80% in telephoto zoom. The brightest portion of the screen was the middle bottom sector, and the dimmest the top left. The difference in brightness on a full white screen was not noticeable, nor was it noticeable in viewing of normal content.
Featuring super-high brightness at 3200 ANSI Lumens, the TK700 is ideal for use in ‘normal’ living room light levels. This means you get vivid, dynamic colour, without having to draw curtains and blinds. HDR calibration for grayscale had similar results. Where HDR calibration will suffer though is in the CMS due to being limited to Rec.709 color space. Prices valid in stores (all including VAT) until close of business on 28th November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) Gaming. I'll start with gaming since it is this projector's primary focus. All gaming was done using BenQ's Game mode with Fast Mode on and Details Adjustment on Low as I found that provided the best balance. During my time with the TK700 I played several games across multiple genres. I started with the Xbox Series X and Halo Infinite. Immediately upon just going into the Series X dashboard I was able to feel the responsiveness. With the Series X I had it set to output at 4K/60Hz, and while in game it felt great. It wasn't as fast as, say, a dedicated gaming monitor or a something like an OLED, but it was pretty good—to the point that I didn't have to change anything with how I play normally to adjust. The HDR added a great sense of depth and highlights. I didn't feel like I was missing anything and being able to play with that level of responsiveness at 100 inches was a real treat.The BenQ TK700 is a very competitively priced, high-lumen gaming projector with excellent input lag suitable for today’s fast-paced gaming. Its performance will allow users to game on the big screen without breaking the bank. It can’t be stressed enough, though, that these response times on a projector are very novel indeed, and given this is a projector with native 4K you’re not going to find better than this performance at the moment. All but a small number of inveterate competitive gamers (or dyed in the wool pedants) are going to notice any input lag. Basically, you’re probably not going to get better performance than this. The TK700 did a decent job with shadow detail and highlights in SDR. In HDR it didn't fare as well as I would have hoped; note that the TK700 does not offer any type of dynamic iris to assist with dark content. Motion was excellent however in everything I demoed while using it from games, to movies, and test patterns. This projector does not have any motion interpolation features, which makes perfect sense considering it is a gaming projector and to get the best performance when it comes to input latency you would want all of that turned off. So it's nice to see it has such good motion on all types of content without the need of such features. For home entertainment, and for gamers who want to move up to a big-screen 4K HDR image and the shortest input lags available, the BenQ TK700 can be a solid entry-level projector. If rainbow artifacts are an issue for you, however, be sure to consider the Optoma UHD35 instead, which offers slightly higher brightness along with essentially the same input lag times, and did a better job of avoiding showing the red-green-blue flashes in our tests.
Input Lag. Input lag measurements were taken using the lag measurement function on a Murideo 8K Seven Generator. Within the TK700's Game picture mode, in the Game Settings menu, Fast Mode must be turned to on to receive the lowest input lag. These measurements were performed three times for each signal listed for a total of 30 measurements. All measurements averaged 2-3ms higher than the measurements listed in specification, though additional testing with other displays suggest this may be attributable to the measuring device. The BenQ W1800 can do up to 15,000 hours in its lamp save mode, but only 8,000 in the most balanced Smart Eco mode and just 4,000 when it’s set to normal. After that, you’re looking at a pricey lamp replacement. The devices I used for reviewing content post-calibration were Xbox Series X, PlayStation 5, Gaming PC with Nvidia GeForce RTX3090 graphics, Oppo UDP-203, and Fire TV 4K.The TK700 utilizes a lamp based light source and Texas Instruments 0.47-inch DLP chip. Any single chip DLP projector has the potential for showing rainbow effects, but fortunately, during my time with the projector, I did not experience any in any content that I viewed. Of course, 4K projectors that use the 0.47-inch DLP DMD are not true native 4K. They actually utilize 4-way XPR (Expanded Pixel Resolution) pixel shift at 240Hz to take the DMD's native 1920x1080 resolution up to 8.3 million pixels on screen. The projector does accept a 3840x2160 resolution signal and it's actually quite sharp, to the point where only those with the keenest eyes would likely be able to see it is not native 4K.
