In the field of projectors, it is divided into industrial projectors and civilian projectors. Industrial projectors are generally used for large-scale concerts. We generally do not have access to households, and civilian-grade projectors are subdivided into commercial projectors. Home projectors, commercial projectors are mainly used for conference speech presentation projections, home projectors tend to build home theaters, and there are subdivided high school low-end, high-end such as Epson's 4K projector, not to mention the low-end In addition, the 2,000 yuan papa and top rice belong to this category, while the midrange market is dominated by the three major brands BenQ, acer and Optoma.
For home projectors, we are looking for cost-effective, high-definition, long-life bulbs. The appropriate brightness and contrast and low price are enough to meet the viewing requirements of the average family, but for commercial projectors, especially light commercial projectors, portable is an important factor, then whether there is to meet the home and light commercial The projectors that both require, BenQ CH100 is even a representative.
packageThis is pseudo out of the box, there is no "hymen", borrowed machine, I have no right to open
The box is a bit long and the pictures on the box are full of literature and art.
Characteristic logo, this projector uses LED light source, theoretically longer life, better brightness uniformity, while the resolution is FULL HD, a variety of basic data is also the mainstream.
Standard projector carrying case, easy to carry.
Standard Accessories, Power Cord, VGA Cable, HDMI Cable, Remote Control
The design space of the carrying case is very compact. After laying down the projector and the standard cable, there is basically no more space. The contents of the supplied CD are instructions, and it is recommended to cancel it. It is more convenient to leave a QR code to scan and download the manual.
Product icon remote control
Because it is located in a portable machine, the remote control is designed as an ultra-thin version, the key position is a basic type, not too much, but also set a fast shortcut such as fast forward rewind, on the battery, the model used is CR2025, this The version of the battery is awkward. Most remote controllers in my hands are used CR2032. It is somewhat difficult to purchase the battery for this remote controller.
Fuselage periphery
From left to right, from top to bottom
First, the front of the projector, the lens and heat sink symmetrical design, the lens is not centered, the front right corner is the infrared receiver.
Second, the back of the projector, here is the interface area, the interface on the back includes the power input, usb power supply, audio input, audio output, 2 HDMI (one of them supports MHL), an S terminal, a VGA interface, miniUSB, and Another infrared receiver, the configuration of two infrared receivers before and after the realization of infrared remote control without dead ends.
Third, the left side of the projector, a large area of ​​the fence opening design, here is the sound output of the speaker, but also the heat vent.
Fourth, the right side of the projector, the same function, the whole machine's heat dissipation opening area is large, to ensure a good heat dissipation.
Fifth, the projector on the surface, CH100 does not have a zoom ring, only the focus ring, it can not be fixed position to achieve the size of the screen to adjust, when lifting the need to strictly measure the distance, at the same time, the surface of a change to the traditional projector design, canceled All the physical buttons, there are three lights next to the zoom ring, and the power switch is in front of the power indicator, using touch control, so the entire top surface looks very simple.
Sixth, the lower surface of the projector, the design of three legs, the first and second after the first and second left and right legs are adjustable design.
Some details
The rear adjustment foot and the front adjustment foot are all adjusted by the knob and the fine adjustment is more convenient.
One after the other infrared receiver module design, behind the fuselage is also equipped with anti-theft lock hole.
The back of the fuselage has a screw-covered lid that opens to reveal a hidden space inside. It has a micro USB cable and a hidden HDMI that can fit into a mini-in-line computer or Android computer stick. more convenient.
Although the back surface of the lifting hole design, but personally think that this machine is suitable for lifting, but built-in universal tripod hole is very good, can be placed on a tripod, mobile lifting is very convenient.
Push-pull lens protection cover, design is very good.
Compared with my 1080st, the length and width are almost the same, but it's too thin and too light.
Use test
Projector menu, the default image mode is sRGB, the official nominal color gamut value reaches 90% of the sRGB, but the sRGB standard is relatively limited compared to the Adobe RGB color gamut, so this data can only be considered good, after all, a lot The projector also failed to reach this value. The other menu settings are basically the BenQ projector's common settings.
The color correction process was first performed by Red Star 5 to obtain 94% of the sRGB color gamut, which exceeds the official data. However, since Red Star 5 is not a professional projection spider, this data is for reference only.
Real shot
The first is to perform trapezoidal correction. The CH100 has automatic trapezoidal correction, but individuals are more accustomed to manual settings and more accurate than automatic correction.
The corrected screen does not correspond to the actual output light source image. Therefore, it can be concluded that the CH100 adopts the digital keystone correction mode. This has the advantage of ensuring that the output distortion that the screen can see through the corrected screen is even smaller. The digital processing capability of the image chip inside the CH100 is displayed, but the disadvantage is that the projection screen is reduced and there is a certain amount of screen size loss.
Projection picture examples, affected by the shooting equipment, the screen and the actual in and out, for reference only.
An enlarged view of the projection of the text and an enlarged view of the effect of projecting a 100-inch screen.
Video display, thanks to the contrast ratio of 100000:1 and brightness of 1000 lumens, the overall picture is bright and colorful. At the same time, it should be pointed out that the brightness difference between 1000 lumens of CH100 and 1080 lumen of 2000 lumens is not obvious. 2000 lumens in the traditional projector, thanks to the adoption of LED light source, the life time of 20,000 hours can basically guarantee the use time of ten years, and the subsequent maintenance cost is relatively low.
to sum up
Take a look at the parameters first.
The CH100 uses a Texas Instruments 0.47'DLP, which is smaller than the common 0.55'0.65', but it also achieves full HD resolution. The use of a smaller DLP size ensures that the entire machine is slim and portable. In the focal length, the projected size is 81 inches at a distance of 2 meters, which belongs to the category of short focus. However, since there is no optical zoom, the projected image is smaller than that of a home short-range projector such as 1080st. The body comes with two 5w speakers for business use. Although the cooling holes on the body are large, the actual cooling noise is not high. The maximum is only 30 decibels, which is even smaller than 1080st.
Comprehensive analysis of advantages and disadvantages
The body is ultra-thin and ultra-light, suitable for portable, but the surface of the glossy design is easy to leave fingerprints.
The design of the hidden space at the bottom is very good, but the fuselage without the system, compared to the new meters and other projectors, there are functional imperfections.
The picture quality is clear and beautiful, the contrast is high, and it is suitable for business projection. However, due to the volume control, the optical zoom ring is cancelled. The size of the projection screen must be adjusted by moving the projector. It is not suitable for lifting.
Price positioning is expensive, the current market price of more than 8000 yuan, compared to individual home users, if there is no commercial demand, not suitable for purchase, compared to commercial users, according to the CH100 parameter design and price, CH100 belongs to a light luxury goods, The quality is guaranteed, the value of the color is also very good, and the price is slightly higher.
