At the end of last year, BenQ released the 4K home projector star series W1700, the first to open 4K precedent million. In the first half of this year, BenQ brought another new product of the Star Series, the TK800, whose brightness rose from 2,200 lumens in the W1700 to 3,000 lumens, making it the brightest model for 4K home projectors within the current million yuan. 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
BenQ TK800
BenQ introduced this projector, called the "Highlight 4K Behemoth," and aimed at the upcoming World Cup this summer. The ability to highlight the anti-ambient light is more conducive to watching the game, and BenQ has also targeted the launch of the "sports model" and "football model" to optimize the dynamic picture, once again demonstrated the strength of the big factory.
So, can TK800 continue the good reputation of W1700? Will the "small cannon of performance", which is more close to the people, meet the fans' demand for watching? This is the answer that this evaluation hopes to tell you.
Blue face is still small and charming
The same series of stars, TK800 and W1700 in the appearance of the main difference is the "front face" of different from dark gray to blue and green, looks more youthful and lively. This brilliant color appears on the projector is really rare, presumably will be liked by young consumers, plus the price of 8999 yuan, even cheaper than a top version of the iPhone X.
The TK800 measures 353 x 135 x 272mm and weighs 4.2 kg. Like the W1700, the TK800 is still small and compact, and it is almost the same size as a regular 1080P model.
The golden "4K HDR" logo is the finishing touch to the machine, indicating that it is a machine that supports 4K Ultra HD resolution (3840*2160), and is not fooled by its compact body.
On the lens side, the TK800 has a throw ratio of 1.47-1.76 and supports 1.2x zoom. It can project 60-300 inches in size, and it needs 3.25 meters to project 100 inches.
On the focus ring, under the zoom ring
Speaking of small details, the TK800's focus ring and zoom ring have a good sense of resistance. It's very common to know that many million-plus home computers, especially the zoom ring, are too common. BenQ’s business and home computers have performed well in this area.
The control buttons and indicator lights are concentrated on the top of the body, including the power button, direction button, menu button, return button, menu button, mode button, and so on. We all know that the lighter's on/off time is relatively long, so the BenQ TK800 will make a "drop" sound after the power on and off, which is convenient for the user to confirm, or very intimate.
Inlet and outlet on both sides
Interface, 2 HDMI interfaces, one of which is HDMI 2.0 & HDCP 2.2, supports 4K 60Hz video input, the other is HDMI 1.4a. 1 VGA port, 1 audio input and 1 audio output interface, 1 USB Type mini B interface, 1 USB Type A interface (1.5A current supply), RS232 interface (access to central control system) and 1 One DC 12V Trigger (3.5mm) connector.
The remote control is a full-function key design with red backlight, and the power switch buttons are set separately to avoid false touches. Especially for hoisting users, it is difficult to determine whether the machine is normally started when starting, and repeatedly press the power button to easily cause a crash. If the remote control button feels softer, the keystroke will be deeper.
Highlighted and more resistant to ambient light to a fearless detonation
Like the W1700, the TK800 is powered by TI's 0.47-inch DMD chip, which uses the XPR technology to exceed the 4K UHD standard defined by the Consumer Technology Association of America (CTA) and can display over 8 million pixels on the screen. .
The actual resolution is 3840×2160, native 16:9 display, contrast ratio 10000:1, support HDR and 3D functions. Light source uses ultra-high voltage ** lamp, life is 4000/10000/8000 hours under normal/economic/SmartEco mode, in the light bulb machine is reached a relatively long life cycle.
Brightness is a major highlight of the TK800, officially rated 3000lm, we use the TES136 illumination colorimeter to test the peak brightness of 2890lm, about 96.3% of the official nominal. In general, home projectors can approach or even exceed the official nominal 95%. The TK800 is absolutely reassuring in terms of brightness.
Open four dome lights
Close all indoor lights
With the indoor four dome lights turned on, the screen is still clearly visible. It is only disturbed by the ambient light that the colors are dim, which is still slightly inferior to that of turning off the lights. However, the brightness of nearly 3000lm has made it possible for home computers to avoid the "light death" phenomenon. When watching a living room or watching a game, they do not have to deliberately pull the curtains tightly.
In terms of color, no rainbow pattern was found due to the use of a high-speed color wheel. The color coordinates of the three primary colors were measured using the TES136, and the gamut value of the TK800 was approximately 64.63% NTSC.
Always good color and football mode blessing
We use OPPO UDP-203 as a signal source to play the 4K Blu-ray disc "Billy Lynn's Midfield War." This film is produced using the HDR10 standard. One of the hallmarks of HDR is high dynamic range, perfect HDR display needs. The display device has a high brightness performance and is ideal for testing this machine.
After the machine is turned on, the input signal source is “3840×2160, 60Hzâ€, and the machine can perfectly support the “60Hz†movie. Compared to ordinary 24Hz movies, the 60Hz screen will appear smoother.
In the above group of screen shots, at noon on the battlefield, the vertical sunlight, you can see, the wall and the ground showing a very vivid solar sun, TK800 highlighted performance can make people feel the scene of hot.
4K ultra-high-definition resolution allows machine **, armbands, bulletproof vests and other details to be legible, and the overall picture contrast is quite strong.
In addition, the TK800 supports HDR brightness adjustment. Since the projector is far from mature when presenting an HDR picture, the preset mode does not always present a perfect picture effect. This facilitates the experience of experienced users according to the characteristics of different videos. Fine-tuning.
In terms of color gamut, the TK800 itself uses BenQ's proprietary CinematicColor color tuning technology and is tuned based on the Rec.709 standard, but the machine also supports the broader DCI-P3 and Rec.2020 standards. "Billy Lynn's Midfielder" is a 4K movie with a very high quality rating based on the Rec.2020 color space standard.
In addition to "Bright", "Vivid TV", "Cinema" and other basic image modes, the TK800 has also joined the "Football" mode.
Turning on the "Football" mode will make a noticeable difference in the "Cinema" mode when playing video games. The first is the higher brightness of the picture, followed by the enhancement of the "green", "yellow" and other course colors, making the colors look more lively.
In addition, DLP's display technology does not have the problem of smearing on LCD TVs. Therefore, when watching a game, the picture is very smooth and the trajectory of football is very clear. With an extra large screen that can project more than 100 inches, the feeling of being on the spot is extraordinary.
The "Football" mode has also made targeted adjustments to the sound effects, reducing noise on ambient sounds, and highlighting the broadcaster's voice, further highlighting the sense of presence.
The BenQ TK800 is equipped with a 5W speaker, which is insignificant in terms of power, but adds the CinemaMaster Audio+2 sound enhancement technology. The volume is large enough. Usually, a size of 10 or so is enough.
Noise and power test
As a machine that will be installed in the living room by users, the noise problem naturally attracts attention. In the living room with a noise level of 32 dB, when the TK800 is in normal operation at a distance of 1 meter from the machine, the noise value is about 34.9 decibels. The performance is quite good, and the noise generated when the machine is running is almost not felt. It can be said to be a quiet “beautyâ€. Man".
Power consumption, measured at 247.5 watts, is similar to the official 240 watts.
Evaluation summary:
BenQ opened the household 4K projection popularity storm with the stars series. As the second machine of the stars series, the TK800 has increased the brightness to 3000lm on the basis of the continuation of the W1700 design, becoming a “highlight†model in 4K home computers.
Without deliberately obscuring the ambient light, it is also easy to watch, and the football model has been specifically launched for the World Cup, which has strengthened the “court color†and enhanced the expressiveness of dynamic images.
From the actual evaluation point of view, this machine while maintaining the highlights, continued BenQ's consistent color adjustment, to achieve a more ideal balance between highlights and colors, manufacturers can be seen.
The World Cup is approaching, and the BenQ 4K projector TK800 with a large screen size of 300 inches will be the next generation of the ball watching artifact.
