In the final analysis, an excellent projector must be outstanding in terms of brightness, color, and light source. With the development of projectors in recent years, there are more and more products that can simultaneously have these three points. For example, NEC (NEC), the Japanese company that was born in 1899, has always appeared as a leader in the projector field. The commercial projector we want to evaluate today is the NEC CF6600U business projector from NEC.
NEC CF6600U Business Projector
Pure and snow-like appearance
The appearance of the Founder of the NEC CF6600U Business Projector lets us understand that this product is not a main entertainment, but a product for business meetings, measurements only 42cm × 133cm × 32.2cm, not in the business-class projector Big, even in the conference room, will not occupy too much space.
If black is a calm atmosphere, then the white must be pure and concise. NEC CF6600U business projectors all use pure white as the main color, and they can be perfectly matched with such environments as meeting rooms.
The design on the back can only be described in terms of simple and complex belts. The rich interface design can meet the needs of most people. Even multi-device connections are stress-free.
The NEC CF6600U Business Projector also designed 20W speakers on the back, which is better than home-level projectors.
The air inlet is designed on the left side of the NEC CF6600U business projector. The shell can be disassembled, and a filter is built inside to prevent particles and other dust from entering the machine.
At the upper right of the machine is the cooling hole of the NEC CF6600U Business Projector. Since this projector has a lamp power of 330W, the requirement for heat dissipation during use is very high, then can it complete the heat? Dissipated? After that, I will tell you the answer through testing.
Physical physical buttons are also designed on the airframe so that users can operate with high efficiency when using them.
The NEC CF6600U Business Projector uses a knob that adjusts the position of the screen to smartly design the top of the fuselage and use a hidden cover to increase the sense of unity. The vertical direction of the adjustment range is +55%, -0%, horizontal direction is ±15%, and the adjustable range is large.
At the lens of the NEC CF6600U Business Projector, there is a joystick that can be adjusted up and down to adjust the size of the projected screen. The projection ratio is 1.2-2.0, and the 30-300 frames of 16:10 can be projected. In addition this projector also has a brightness of 5600 lumens and 20000:1 contrast ratio and WUXGA (1920 * 1200) standard resolution, the specific display effect, we will later test.
The NEC CF6600U Business Projector's original remote control is still NEC's family-style design, highlights are far less than the other features of this product, but randomly included two batteries on the 7th, is still a conscience.
How bright is 5,600 lumens?
We all know that the average projector lumen value can reach about 3,000 is considered to be good, but since ancient times it is strong and its own strong, NEC CF6600U business projector lumens directly reached 5600, which means that even if the meeting The room has ample light and does not affect the projector's display.
The above picture shows the real shot after the lights, the following figure is off the real shot
When the conference room lights were all lit, the screens dropped almost without losing levels, and the ultra-high contrast ratio of 20,000:1 made the colors more pure and did not appear gray. This was in contrast to the 330W bulb used in this unit. There are inseparable links.
Limit test
During the test, the author intentionally used the four-inch permanent light that was used to shoot the product to illuminate the screen. In this super bright situation, the screen projected by the NEC CF6600U business projector was grayed out. However, in this case, when it was almost impossible to use it in daily use, we did a limit test.
Quality determines success or failure
NEC CF6600U Business Projector has built-in 7 kinds of display effects, namely standard, presentation, video, movie, graphics, sRGB standard color and DICOM SIM. We can set the most suitable mode for different situations.
In order to make the picture color more accurate, NEC CF6600U business projector uses 3LCD technology, in simple terms 3LCD is three LCD panels, through the divergence, color separation is divided into red, green, blue three colors, and then through the mirror fold After the reflection, the light is concentrated on the core component HTPS, and the intermediate prisms mix the three primary colors to project clear, bright, and natural images. How is the actual performance? Through testing, we have found that the NEC CF6600U Business Projector stands out in terms of both color and overall look and feel.
First talk about the resolving power. After testing, NEC CF6600U business projectors have completely separated the lines of the screen, no blocking occurs, and excellent lens performance guarantees polar distortion.
Through the color transition test, we found that the NEC CF6600U business projector showed slightly insufficient performance when displaying red, and it was prone to excessive unnaturalness when watching a video display of a red screen.
When the NEC CF6600U business projector is tested in grayscale, whether it is 56 gray scales or 256 gray scales, each gray scale digital mark is very clear, and the adjacent blocks are also clear.
Next let's enjoy the screen shot proofs. (After the screen shot proofs are taken for multiple digital conversions and the reader's display device performance is only for reference)
This set of proofs clearly shows the advantages of 3LCD. The control of color is very good, vivid colors, and it looks more like eyeballs. Even if there are multiple lights on the proofs, it will not be overexposed. If this projector manufacturer does not have years of experience, it cannot be done.
Standby test
Since the NEC CF6600U business projector is mainly aimed at the office business field, we tested the heat, power consumption and noise of the NEC CF6600U business projector.
After testing, the NEC CF6600U business projector has a power consumption of 252.9 watts under the condition of watching PPT and other documents, and 322.8 watts in the normal playback mode, which is excellent in business projectors.
After 10 minutes of playing the movie, we conducted a temperature test on the top of the fuselage and the heat vent. Measured, the top of the fuselage is 31.5 degrees Celsius, and the temperature at the vent is 59.7 degrees Celsius.
Noise control has always been NEC's strength. When it is close to the machine, the measured decibel is 40.9dB. When tested from the normal position, the decibel is about 35dB, and almost no obvious noise can be heard.
Summary: Exclusive meeting room desk
When I light up the NEC CF6600U Business Projector and see the projected picture, this machine will immediately take advantage of 3LCD. This moment really made me forget that this is a projector. Whether it is in the brightness or the accuracy of color reproduction has reached the top level of office business. In general, this projector is absolutely capable of meeting the daily office needs of most companies.
