Epson projector CH-TW650 has a body size of 302 × 249 × 87mm and a weight of about 2.7kg. Overall milky white. As a "commercial and residential" dual-purpose model, it tends to be business oriented in appearance. I think it's still the most eye-catching and easy to integrate with the surrounding environment. The side and bottom surfaces of the fuselage are matte plastic. The surface of the top cover plate is bright paint. The normal operation and setting can be separated from the remote control and directly use the buttons on the machine body. The detailed setting and operation still need to be carried out through the remote control. The remote control is milky white as the main body, small and thick, so it has a good grip. The key is a little small, and the handle is not very good. It does not have the function of backlight, so it is a little inconvenient to operate in low light.
Epson Projector CH-TW650 lens
The upper part of the lens is a manual adjustment area. There are four adjustment levers from the outside to the inside. The functions are: lens cover opening and closing, focusing, zooming (zooming), and trapezoid correction. When pulling, it has a good sense of damping and a linear feeling, so it is easy to carry out accurate positioning. Open the lens cover and you can see the lens inside. The outer layer of the lens is green coating, which looks very beautiful. This lens is shorter than the focal length of the ordinary home projector lens, and can project a larger size at the same distance. 100 inches minimum two point two seven Meters.
Epson Projector CH-TW650 Power
The bulb model of CH-TW650 is elpld 96 (200W), which can provide 4500 hours in standard mode and 7500 hours in eco energy-saving mode. Take off the screw, open the cover plate, you can see the lamp group, and it is convenient to replace by yourself, which is not too difficult.
The left side of the rear part of the fuselage is the interface area, which are: power socket, USB-A, USA-B, AV interface, VGA, Hdmi1, Hdmi2 (MHL). The top cover position is marked with the names of each interface. The black round window is a rear infrared receiver. On the right is a 2W speaker.

Place the projector in a proper position, plug in the power supply and connect the computer, and then turn on the projector. The whole adjustment process is very convenient. The "test pattern" is provided in the setting menu for reference during adjustment. In addition to automatic adjustment, trapezoid adjustment also provides two manual adjustment modes of "horizontal / vertical trapezoid correction" and "quick corner correction".
Epson Projector CH-TW650 Color
Four color modes: dynamic, bright cinema, cinema, game. These modes differ in brightness, contrast, color, and sharpness. The dynamic and bright cinema is the brightest, which belongs to the normal mode. In the two modes, the power consumption and noise are the largest, which are suitable for use in strong light such as daytime or light. The cinema and game mode are eco energy-saving mode, which are less power consumption and noise, and the environment light is not too strong, especially in the case of all black.
Epson Projector CH-TW650 noise, temperature, power consumption
Eco energy saving mode
Noise test: Eco mode (cinema, game), with some obvious noise, but not too noisy
Temperature test: in eco mode (cinema, game), the temperature of the outlet wind fluctuates in the range of 60 ℃ - 65 ℃
Power consumption test: Eco mode (cinema, game)
Normal mode
Noise test: in normal mode (dynamic, bright cinema), the noise over 60dB is noisy
Temperature test: under normal mode (dynamic and bright Cinema mode), the temperature of outlet air fluctuates in the range of 70 ℃ - 75 ℃
Power consumption test: normal mode (dynamic, bright cinema)
Draw the curtains and turn off all lights (not all black)
3100 lumen brightness, daytime use is completely feasible. In the case of strong light, although the picture is gray, the details can still be expressed, and the main change is the color.
It's a little too bright to use dynamic color mode in all black. The most popular mode is bright Cinema mode. In this environment, it is more appropriate to use eco energy saving (cinema, game).
In the actual test, the color gamut of Epson ch-tw650 is 88% sRGB, 66% NTSC, 68% Adobe RGB. Reached 88% sRGB, the actual sense is good, which is a good result.
In terms of color accuracy, the average value is four point one one , a little bit larger. The deviation between blue and green is obvious, and red is accurate. The test results are in good agreement with the comparison of the above three primary colors.
Split screen (dual screen) mode
A projection display two screen display function. It is convenient to play games or movies while surfing the Internet. Very practical function.
Wireless phone connection
First install Epson's "iProjection" app on the mobile phone, and then use the mobile phone to scan the code to connect to the WiFi on the projector to complete the quick connection. The mobile phone can send pictures to the large projection screen through wireless connection. It's very convenient to share photos with family and friends everyday.
Hdmi2 interface also supports MHL data line connection function. Mobile phones with MHL function can share pictures to projection through data line.
Epson Projector CH-TW650 Summary
Advantages:
1. Commercial and residential models, with 3100 lumen brightness, also have a good effect in the daytime or under the light;
2. 1080p Full HD resolution, 3lcd technology, clear display, colorful;
3. It supports desktop placement and ceiling installation, side projection and automatic trapezoid correction. Easy to use.
Disadvantages:
1. For commercial use, a shorter focal length is used compared with the home model. For home use, the width of the conventional living room is about 4 meters, and the picture size of the wall mounted installation is 150 inches, some of which are large;
2. In normal mode, the noise of the cooling fan reaches 65dB, slightly larger;
3. There is no 3D function configured for home use.
In general, Epson projector CH-TW650 is impressive and satisfying in terms of brightness and color. Even in the daytime use can obtain the good picture effect. At the same time, it also provides practical functions such as split screen display, wireless connection, MHL and so on, with various playing methods. There are also three installation methods of desktop placement, lifting and side projection. The completion can meet both commercial and domestic needs.
The problem of too much noise in the standard mode, for bulb models, high brightness must have high heat, and higher heat dissipation performance will be required, so noise is inevitable. In fact, the noise problem in actual use has little impact. The environment is noisy in the daytime, and the noise does not sound particularly prominent. At night, the eco energy-saving mode can get a good picture effect. In this mode, the noise is relatively small and does not cause discomfort.
The price of 5000 yuan can provide such excellent display effect and rich functions. Epson Projector CH-TW650 is undoubtedly a very cost-effective and competitive projector.
