UHD/HDR Viewing. Viewing HDR on the TK700 was somewhat hit or miss. It was excellent overall while gaming, which again is this projector's primary focus. In higher APL (average picture level) scenes for both gaming and movies it also performed very well. It was in movies that had dark scenes with low APL where it sometimes performed well and at other times not so much. Brightness. The TK700 is rated for 3,200 ANSI lumens. The brightest picture mode in both SDR and HDR was Bright while in Normal lamp mode. In SDR, this picture mode measured 2,818 ANSI lumens, which is 12% lower than its rated specification. HDR10 mode in HDR measured 2,796 ANSI lumens, which is 13% under the rated spec. Rivals have the W1800 beaten when it comes to HDR, brightness and contrast, then, but you’ll struggle to find another 4K projector at this price that delivers a more natural, cinematic image.
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. 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. Featuring 4K resolution, the TK700 maximises the graphic content from the latest games. Unlike other projectors, the signal is native, not upsampled. This means you get to see the colours, texture and depth of the game – just as the game creator intended. HDR takes the picture to the next level, with crystal-clear detail – even within the darkest areas of the screen. Regardless of your preferred mode for movies and video, Game mode is the obvious choice for gaming, both for the better shadow detail—the faster you can see what's happening in the shadows, the faster you can react to it—and for its state-of-the-art short lag times for projectors. My Bodnar meter timed the input lag for 4K 60Hz input at 17.0 milliseconds (ms). For 1080p, the lag was 16.9ms at 60Hz, 8.5ms at 120Hz, and 4.3ms at 240Hz.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.
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. 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.The projector also has a relatively short throw of 1.3:1 with the zoom control at full, giving you a 100in picture at a distance of only 2.5m. The only worrying spec is a maximum brightness of just 2,000 ANSI lumens. BenQ W1800 review: Price and competition 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.
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. 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. Calibrated image settings from any third-party do not account for the significant potential for sample-to-sample variation, nor the different screen sizes and materials, lighting, lamp usage, or other environmental factors that can affect image quality. Projectors should always be calibrated in the user's own space and tuned for the expected viewing conditions. However, the settings provided here may be a helpful starting point for some. Always record your current settings before making adjustments so you can return to them as desired. Refer to the Performance section for some context for each calibration. SDR 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 next game I wanted to try was Gran Turismo 7 on PlayStation 5. This game also required a small amount of time to adjust to the difference in latency, though it took less time than with King of Fighters. Unfortunately, GT7 does not have a 120fps mode. While running the game in its 4K/60 HDR mode I found that my breaking was slightly off when going around corners. Outside of that everything else virtually felt the same as when played on my OLED. This was another game that was displayed beautifully on the projector with rich and vibrant colors, great HDR, and pure immersion. Another treat playing at 100 inches in HDR.
Lacking One Picture Mode to Rule Them All
It’s the colours that swing it for the W1800, though. Not only did this projector slightly exceed Rec.709 in testing but colour accuracy is fantastic by projector standards, with an average Delta E of 2.89. Its only serious rival here is the Viewsonic X10-4K and that’s slightly more expensive. Additionally, the TK700 includes one 5W chamber speaker that utilizes treVolo and Bongiovi DPS technology, which optimizes the audio signal in an attempt to add depth and immersion to the sound. This is available in the included Cinema, Music, Game, Sports, and User presets. I found the speaker suitable for some content such as watching YouTube or something of the like, however it was not really suitable for movies and an external audio solution is highly recommended such as a soundbar or AVR and speakers.
