The selling points of the BenQ W2700 are printed on the box. This is an ultra-high-definition projector that supports 4K HDR, and its HDR is still the PRO version. It does not simply support HDR format, but has made a series of optimizations to support HDR 10 and HLG. HLG is designed for TV broadcasting, which means that the initial design of this projector should have considered users using it for daily TV watching.
BenQ W2700 Features
The high-speed six-color wheel seems to be a standard configuration. Compared with the three-color wheel, the rainbow effect will be reduced a lot. There is nothing to show off.
Wide color gamut, the film industry standard DCI-P3 color gamut, most projectors are currently Rec.709, UHD standard Rec.2020 hardware technology can not keep up, P3 should gradually become the industry standard.
3D support, I remember that the first batch of 4K projectors were basically semi-finished, with low brightness, narrow color gamut, and also did not support 3D. The old version of 0.47 DMD chip "fake 4K" was also scolded. With the iteration of technology, the technology has become more and more mature, and it has begun to support 3D, HDR mapping technology is getting better and better, and the price is no longer out of reach.
MEMC motion compensation, or frame insertion, can increase the picture from 24Hz to 60Hz, which can improve the tailing phenomenon of dynamic pictures, and play games, watch sports games and action movies more smoothly.
It also supports direct reading of USB media files, vertical lens shift and short focus design.
BenQ W2700 D.Cinema image mode can reach 100% Rec.709 color gamut coverage in the factory state, while User mode can directly achieve 95% DCI-P3 color gamut coverage.
The brushed metal front panel and the metal mesh cover back panel matched with the white body are quite beautiful. On the front panel, there is an 8-group 10-element all-glass lens with a metal lens barrel. There is a light-leakage shield under the lens. It will not affect the screen display when actual use. The advantages of the glass lens are obvious. Relatively speaking, it can make the picture more pure, transparent and sharp, and there is no thermal defocus problem of the resin lens.
There is an infrared receiver next to it for easy remote control. There is a push-adjustable support foot pad at the bottom of the front, which is convenient to adjust the height of the picture when it is placed on the coffee table and other places. With automatic vertical keystone correction, it is much easier to use than the vertical lens shift on the lens. There is a small cover on the upper part of the lens. After pushing it open, you can see the focus ring, zoom ring and a vertical lens shift knob which can be used to adjust the picture position, picture size and picture focus. The lossless lens shift can only be adjusted vertically, and the moving range is 10%, which can only be used for fine-tuning.
There is a control area on the upper cover of W2700 with several most commonly used buttons and running status indicators. If the remote control is lost, all settings can be adjusted here. There is also an infrared receiver on the top cover, which is convenient for remote operation when the projector is hoisted.
Facing the projector lens, the right side is the air inlet, and the left is the air outlet. The hole is very large. I think the design is a bit rough. The air outlet has a large air volume and temperature. It is very high. The measured temperature is about 56 degrees in one hour after starting up. It's like a small air conditioner. The corresponding noise is also louder. The test noise at the air outlet is about 60dB. Of course, in the case of watching a movie, the ears can't be so close to the projector, and the sound will be masked and basically not heard. In addition, it will be better to turn on the energy saving mode.
The back interface finally abandoned the VGA interface on the commercial machine mold. On the left is a 12V linkage interface (need to be turned on in the setting menu), which can be embedded in a network cable during decoration, and linked with AV power amplifiers and electric screens to achieve simple automatic control. To realize more powerful intelligent control, it is necessary to connect the central control host with the 232 interface next to it.
The next MiniUSB port is generally not used and can be ignored. The USB 3.0 interface is used to insert a U disk or a mobile hard disk. The built-in player can directly read videos, music, documents and photos. After a test, the stereo video can be played normally. The surround sound track is not supported, and the original Blu-ray disk cannot Read. This function is easy to use. If you are a true audio-visual enthusiast, you should use a professional player.
Both HDMI interfaces are HDCP 2.2, and all support 4K. There is also a USB port on the right. If you use some high-end HDMI cables, you can plug it here if you need power supply, or you can plug it here for power supply using a wireless HDMI receiver.
There are two audio output ports on the far right side, a SPDIF optical port, and a 3.5mm stereo output port for external multimedia speakers, which can be ignored by home theater users. Note that there is an ISF certified icon next to it, indicating that this product supports professional video adjustment and has been debugged.
Press the "MENU" button to see the system operation interface. The first thing to bear is the image mode. There are five options (Bright, Vivid TV, Cinema, D. Cinema, User). In fact, there is a hidden HDR mode that needs to be activated by playing HDR sources. After adjusting the HDR mode, the improvement is not very large, and the user basically just fine-tunes it for the environment and the screen. For ordinary users, the debugging operation is simplified. Personally suggest that D.Cinema image mode is preferred for old movies, and User image mode for new movies is more ideal.
If BenQ W2700 is used as an entry-level 4K projector for living room theater, I think it is competent and cost-effective. However, it is not perfect. I can still see a slight rainbow in actual viewing, but only when the white icon or text is displayed, it has little effect. There is also a light path design problem that causes blue overflow at the edge of the text. Another thing is that the 100-inch screen feels just right to use. If the screen exceeds 130 inches, the brightness is worrying. In addition, friends who have bought the BenQ W2700 projector must pay attention to it. It does not support horizontal lens shift and horizontal keystone correction. You must ensure that the projector lens is in the middle of the screen.
