Foreword:
With the constant pursuit of quality of life, people are not content to go to the cinema to enjoy the visual feast once and for all. More and more people choose to build a home theater system. Among them, the projector as an important part of this system has always been the focus of many consumers. With the continuous advancement of technology, the choice of household projectors on the market has become more and more abundant, and prices have become closer to the people. Recently, the YORK evaluation room received NEC NP-CD3100H full HD home theater projector, to see how it is in the increasingly fierce home projector market performance?
Appearance details Appreciation:
From the design point of view, NEC NP-CD3100H uses the NEC projector family commonly used white style, square body, shell is plastic matte material, non-slip and will not leave fingerprints. The body is very sturdy and white looks stylish.
As a home projector, not only is the face value outstanding, but also the size is controlled properly. The size of 324x88x250mm and the weight of 2.9 kg will not be particularly occupied in the home. The corners have been rounded to facilitate movement.
The machine adopts a front and side air outlet design. There are two cooling fans on the inside, which can accelerate heat dissipation more effectively and keep the machine running stably for a long time. At the same time, double-layer ventilation fences are used to effectively increase the dust-proof area and easily deal with dust challenges in the home environment.
The control button is placed on the top of the body, and the power button and other button partitions are placed to prevent misoperation. The main buttons are menu keys, signal sources, trapezoidal correction, direction keys, volume plus/minus keys, and the like, which can be easily operated even without a remote controller. The button feels crisp and the feedback is clear.
The top logo shows that the machine supports MHL, HDMI, and DLP technology.
The projector has multiple lifting interfaces and supports ±30° horizontal vertical trapezoidal correction for easier lifting.
Interfaces and accessories
The NEC NP-CD3100H comes standard with a power cord, remote control, and VGA cable. Unfortunately, no commonly used HDMI cable is included. As a machine with two HDMI interfaces and MHL support, it is natural to have a HDMI.
Projection operation
NEC NP-CD3100H projection menu is relatively simple, including common operations, no fancy features.
In the "Image" setting, you can set the image mode, wall color, brightness, contrast, etc.
As can be seen in the source options, NEC NP-CD3100H supports one computer, two HDMI interface devices and video input.
The NEC NP-CD3100H supports vertical and horizontal keystone correction functions, eliminating the need to distort the positional deviation when placing the projector. This function has gradually become one of the projector's standard functions, but the NEC NP-CD3100H does not support automatic trapezoidal correction, and manual adjustment is still required when the angle deviation is encountered. This is somewhat not smart enough.
In the azimuth, the machine supports desktop front projection, desktop rear projection, ceiling ceiling projection, and ceiling rear projection in four orientations, which can meet the needs of non-use scenarios.
In the lamp setting, you can see the remaining life, usage time, etc. You can also turn on the energy-saving mode to reduce power consumption.
Display performance test
At the same time, we conducted more detailed tests on the NEC NP-CD3100H's color transition and three primary color reduction capabilities to test the potential strength of this product. (Because of the multiple digital conversions after taking the screen shots and the performance of the reader's display equipment, they are for reference only.)
From the RGB three primary color test results, this machine can more truly restore the color, thanks to the use of the optimized 6-color segment color wheel technology, based on the three primary colors of red, green and blue, increase the over color of three colors of blue and white, Makes the color gamut wider and the colors more vivid.
In the color gradation screen, the NEC NP-CD3100H has a natural color transition with clear boundaries between color patches. Even the green blocks at the top of the pyramid performed well, but the red blocks at the edges did not perform well.
In the color saturation test, this machine's color display tends to be natural, closer to the true view, not too bright.
Samples, photos to enjoy
We connect the projector to a Blu-ray HD player and restore the high-resolution artwork of “Star Wars: Awakening†through the HDMI interface. Let's take a look at the picture display capabilities of this home projector. . (There is a certain deviation between the screen shot and the actual effect, the screen shot is for reference only)
It can be seen from the actual measurement that the NEC NP-CD3100H is very good at color reproduction and detailed performance. The contrast between light and shade is outstanding, and the outline of the object can be well presented in dark scenes. Sports scene without smearing, enough brightness, no expense, can meet the family viewing needs. Unfortunately, only a speaker with an 8-watt mono is available. Although loud enough, it is still lacking in stereo.
Environmental testing
For home projectors, many people will pay more attention to environmental protection such as power consumption, noise and temperature.
After running for a period of time, the measured power consumption is about 265.4 watts, which belongs to the general level of home projectors. If you choose energy-saving mode, the power consumption will be lower.
In terms of noise tests, the actual performance is that sounds can be heard only in close proximity to the fuselage, with little impact on the viewing experience.
In terms of heat, the two sides of the air outlet can feel obvious heat, and the temperature of other parts of the body is normal.
to sum up
For the home theater projection market, the NEC NP-CD3100H stands out from the crowd with its 3,000 lumens of high-brightness, 1080P full-HD resolution and six-color color wheel technology, which is the easiest place to impress users. In addition, the embedded lens, dust-proof double fence, low noise and heat, where the user's perception is not obvious, NEC NP-CD3100H also brought surprise performance. As an internal and external repair, there is no obvious short-board home projector, plus it is not expensive price, is an ideal choice for individuals to set up a home theater.

NEC NP-CD3100H
First look at the main parameters: NEC NP-CD3100H with 1080p (1920 × 1080) full HD real resolution, equipped with six color wheel color technology, brightness of 3000 lumens, contrast 8000:1, can project 40-300 inch screen size, Support Blu-ray 3D format, built-in 8 watt speakers.

Embedded lens
The benefits of the embedded lens are to prevent dust accumulation, better protection of the lens, and longer life. Focus ring and zoom ring
The focus ring and zoom ring above the lens support manual and manual focus with a zoom ratio of 1.2, an aperture of 2.6-2.9, and a focal length of 22.4-26.8 mm. Interfaces and accessories
The NEC NP-CD3100H comes standard with a power cord, remote control, and VGA cable. Unfortunately, no commonly used HDMI cable is included. As a machine with two HDMI interfaces and MHL support, it is natural to have a HDMI.
All accessories
remote control
The interfaces are all located on the back of the machine, and the common interfaces are very complete. VGA, HDMI, audio and video input and output interfaces, etc., and access to all types of home audio-visual entertainment devices are sufficient. NEC NP-CD3100H projection menu is relatively simple, including common operations, no fancy features.
A variety of wall colors are available
In the process of using the projector, there is often a case where there is no projection screen, and in particular, the probability of desktop projection encountering such problems is even greater. So, what's a good way to ensure that the projection screen displays colors properly? The current solution is the "wall color" adjustment.
