User picture mode uncalibrated is 99.6% as bright as Bright picture mode and HDR10 picture mode is 99.2% as bright. Zoom Lens Light Loss. The TK700's light loss when shifting from the widest zoom ring position to its longest telephoto ring position was 16.1%. For HDR, the TK700 supports both HDR10 and HLG. When using the HDR10 discs in our 4K viewing tests, it offered two color mode choices: HDR10 and HDR Game. For my tests, I chose HDR10 for its obviously better contrast. Colors were acceptably accurate, and shadow detail held nicely. I didn't notice any obvious improvement in picture quality compared with viewing the same scenes in their SDR versions, but the image quality was at least as good with HDR, which isn't true for all projectors. As with most models that have HDR support, the TK700 offers a setting—labeled HDR Brightness in this case— which you'll need to adjust for your room brightness, and possibly from one video source to the next, to find the best setting.

The 3,200 ANSI lumen rating for the TK700 is enough to fill a 260-inch diagonal, 1.0 gain 16:9 screen in a dark room, according to Society of Motion Picture and Television Engineers (SMPTE) recommendations. Using the lower brightness Game mode, the image was easily enough for a 90-inch 1.0-gain screen in a dark room, or an 80-inch screen in a family room at night with lights on. In the daytime with the same 80-inch screen and light streaming through windows, the image was watchable, but washed out. Among the other notable features of the TK700 is 3D, which is actually very bright when triggered, though the projector does not offer any control to increase or decrease the 3D effect. Also, the TK700 includes BenQ's LumiExpert, which is useful for automatically adjusting perceived brightness by tweaking the gamma based on the ambient light in the room. This feature may prove useful if you place this projector in a multi-purpose room such as a living room that has a fair amount of ambient light that changes throughout the day or you like to watch with different levels of room lighting at different times.Users who would calibrate will be glad to know you can get a fairly accurate picture with the controls given. The controls provided within the projector are your standard fare of 2-point grayscale controls and CMS (color management system) to adjust RGBCMY primary and secondary color points. These same controls are available in HDR picture modes as well. Grayscale can be dialed in nicely, though given the gamut specification, color can't be dialed in to fully cover the Rec.709 color space, and there's no support for WCG (wide color gamut) for HDR. Using the provided 2-point grayscale controls I targeted the production industry standard D65 neutral gray white point. Afterwards, a full CMS (color management system) calibration for the RGBCMY primaries and secondary colors was performed as well. Results for post calibration grayscale came in very well given the TK700 only has a 2-point control for grayscale. Max DeltaE was 2.6 for 100% white, while 3 points were under 2dE, the rest being under 1dE. With the CMS portion I targeted 75% saturation and luminance so as to capture where the majority of content resides. 80% and lower looked great though for 100% saturated colors the dE max figures were as high as 8dE. 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.

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. For audio, the onboard 5-watt chamber speaker delivered sufficiently high quality to be usable at high enough volume to fill a small to medium size room. For better quality, you can connect an external audio system using the 3.5mm audio out port or the one HDMI port that offers audio return. 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. 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. Similar to its predecessor, the TK700 has a specification of covering 96% of the Rec.709 color gamut; we verified it with a very close measurement of 94.6%. So, while there are definitely some similarities between the two models, the most obvious difference is in throw ratio, where the TK700's 1.3X zoom is spec'd at 1.13 to 1.46:1. The TK700 also has only one special genre-based game mode where its predecessor had three (more on that below). Outside of the obvious difference in the lens (which has a shroud on the TK700STi to prevent light spill) and a few various markings, such as the LumiExpert and 4K badges, the design of the TK700 and TK700STi look identical.The color temperature settings that were most accurate out of the box were actually Native and Cool, which provided a tighter grayscale until about 50% stimuli (brightness) and then starts to push blue through the remainder of the grayscale as it gets brighter. The Normal and Warm color temperature settings pushed red throughout the entire grayscale range. Measurements also revealed that Native color temperature put colors within the Rec.709 color space closer to being on target as well. 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.
