# original innovator # new home audio and video - NEC NP-CD3100H home projector evaluation

With the continuous improvement of living standards, we are also pursuing a higher quality of life, so the demand for home entertainment has also been a qualitative change. More and more people began to choose projectors to form their own home theater, of course, including me. Taking advantage of 618 recent activities, quickly started with a NEC NP-CD3100H and casually with a bracket-style curtain to experience it. Fancy this machine for a long time, more like the brand. International practice, first open the box.

The NEC NP-CD3100H uses DLP display technology to support 2D content conversion to 3D, 3000 ANSI stream brightness, 1080p resolution, up to 8000:1 contrast ratio, using ultra-high pressure mercury lamps, lamp life up to 6000 hours, comes with An 8 watt speaker.

The box of the NEC NP-CD3100H is a rectangular box with various prompts. The packaging is relatively simple, but most of the slightly larger items are packaged like this. This kind of carton is thicker and more reliable.

Not much to say, cut the subject. Open the package quickly and take the NEC NP-CD3100H out to study all the details.

Power cord, VGA cable, remote control, CD, remote control battery, manual, warranty warranty card nationwide.

The NEC NP-CD3100H uses the most common white color scheme for home projectors. It is compact and stylish. White is a versatile color that blends well with different styles of decoration and the home environment. It will not be a big deal. The square body is accompanied by a rounded corner to make the body more visually comfortable. The net amount of NEC NP-CD3100H is only 2.9KG. I compare it with JD. It is lighter than most home projectors. The size of the body is 324*88*250mm, and the thickness is relatively more than most. Home projectors should be thinner. The light and stylish body is very convenient whether placed on the desktop or on the ceiling. Because I just bought it, I still use it on the desktop.

The front and sides of the NEC NP-CD3100H have cooling vents, which can ensure the stability of the projector for a long time by combining heat dissipation at multiple angles. As shown in the figure below the center of the front of the fuselage, is a switch for adjusting the projection angle of the projector body. The usage differs from that of a screw in that it requires you to press the ejected part and then move the stand up and down. After adjusting the angle, release the pop-up switch to fix it. The NEC NP-CD3100H uses a 1.2x zoom lens that can project a 40-300-inch projection screen based on the distance from the living room.

The interface is also important for the projector. I took it into consideration when choosing it, because now I still use HDMI at home, and the NEC NP-CD3100H has two HDMI interfaces. I'm still very satisfied. There is also a VGA connection, a USB interface, an MHL interface, a network interface, two audio interfaces, and a control serial port slot (D-Sub 9-pin).

The rightmost interface is a traditional, legacy interface that can connect to older set-top boxes. Of course I still choose to use the HDMI interface.

Again a few details, NEC's LOGO, power button, simple menu keys above the fuselage. The NEC NP-CD3100H is certified by the China Environmental Protection Association and the China Energy Conservation Certification. Therefore, the total power consumption should not be too large. This will only be felt in the future.

Look at the remote control again, this remote control I like very much, many settings have shortcut buttons. Of course, I haven't used other brand projectors yet so I don't know if other brand's remote controllers are the same. After I used it, I discovered that the remote control had almost all the options in the menu. For example: image, trapezoidal correction, zoom, etc. are very convenient to use. The most interesting thing is the center button of the remote control. NEC printed a "decision". Each time you press it feels special.

The projection screen will not be described in detail. It is chosen arbitrarily. Because I did not really understand this, I chose to play with a screen. Folded, you can fold up and stand at the corner.

After the curtain was unfolded, it was really like a model, and it instantly felt like a small family room.

NEC NP-CD3100H is very convenient to use HDMI and notebook computer connection, you only need to connect HDMI laptop and projector, and then boot, press the "HDMI1" on the remote control to select, and then talk about the computer to switch to copy screen mode, ie The computer's image can be projected onto the screen. When the projector is used for the first time, you will be prompted to select a language. The CD3100H provides 30 optional languages ​​such as Simplified Chinese, Traditional Chinese, English, Japanese, and Korean. I chose "Simplified Chinese". After all, my mother tongue is still familiar.

Let's take a look at the effect of the projection. I personally think that it is very much appreciated. Both the color and the clarity are first-class and really satisfying. Of course, I did fine-tuning, such as trapezoidal correction, fine-tuning the focal length. One will show you the menu and you will know where to adjust.

Because I've already tossed and understood it, I took the picture and wrote this review, so when I connect a laptop and play a video, the background of the menu won't be a pure blue background. The menu has "image", "screen", "settings" and other options. You can set different requirements for yourself through these tabs. Brightness, contrast, sharpness, and image modes can all be found here. Of course, there are many shortcut keys that have been said to have full-featured remote controls. You can enter these settings at the touch of a button. I personally think it is very convenient.

The 3D switch can be set in the "Screen" option. It is said that 2D can be converted to 3D. This is a more interesting feature, so that some TV dramas and movies can have a slight sense of 3D.

The remote control also has a soft-off function. After pressing the shutdown button, the system will prompt whether to shut down. In this way, you can also avoid frequent pressing of the machine's switch button, although we all know that the projector's keys have been stress tested, can withstand more than the life of the projector press, but there is a soft shutdown sometimes very convenient. For example, if you are tired and want to rest, you don't want to go past the projector, then you can close it with the remote control.

The original intention of buying this projector was to enjoy TV series, movies and concerts at home. Working day by day, the weather is hot outside, and the necessity of home and weekend work is still critical. Recently, there was a very popular TV series Chu Chuo Chuan. After the machine was bought and returned, it was tested on this TV series. Oddly enough, the television at home is not very small, 50 inches, but the family is rarely seen. Maybe it was because the projector was fresh enough. From installation to testing, my family was around me. My mother also took a video to send a circle of friends and said watching movies at home. Before everybody used their mobile phones to watch some video or something, the appearance of this projector also brought the family closer together, and it felt very good. Afterwards, the whole family can pursue dramas and watch movies together at home. Haha, returning from the past, let's take a look at the effect of Chu Chuo Biography.

First of all, a few lights on the effect of the home's light is an ordinary LED warm yellow ceiling lamp, living room and dining room are open. Real performance is better than pictures. Is it not obvious that there will be a drop of yellow light from the top of the curtain? In fact, we do not rule out watching movies at home and the TV shows do not turn on the lights. However, the CD3100H has a brightness of 3,000 lumens, so turning on the lights is not a problem and the brightness and color are still perfect.

Then a few lights off the effect, the CD3100H projected screen gives me the feeling that the color is more full, doing a very good job in the processing of the three primary colors, red and blue bi-color in the brightness and color performance and reduction ability is particularly satisfying to me, but Green is a little weaker in saturation, and of course I also know that the most expensive display product is green. The better the green performance of a device with the same display technology, the higher the price of the device. Because it's sometimes the screen may be slightly overexposed, please forgive me.

Well, every officer, "Chuo Chuan" first see here. I'm the "Transformers" mystery, to a few "Transformers." In contrast, the pictures of some movies may be slightly darker than those of television dramas, such as some of the scenes of Transformers. The CD3100H is well represented in the details of the dark field, and the actual display is better than the photo. You can see from the picture below that the hair is in a black background, but still can see the outline more clearly.

Looking at the dark field performance under the hood of this Hornet, you can see the black clothes and arms, as well as the contrast and excessive between the hood and the head, are very natural and distinct. Can not help but sigh, Megan Fox this little man waist.

Once again, the Hornet's color and details are all very good.

The performance of the CD3100H's backlit screen is also quite satisfying to me. I sigh that it is really a pleasure to watch a big movie at home.

Concerts should be entertainment items that many people like to watch and listen to. Me too, I personally like Zhang Xueyou and Leslie Cheung. Leslie Cheung (brother) has left us, but Xueyou still continues. The following is the projection effect of “Miss YOU MUCH LESLIE continues to pamper the Leslie Cheung concert for ten years”. The CD3100H performed perfectly on the red clothes and blue background of the schoolmates. With the large-size screen, the scene is very strong.

3D is now very popular, and 3D sources have gradually increased, but the CD3100H has a 2D to 3D function, which is more convenient. We can enjoy the 3D effects of TV dramas and other 2D movies through 2D to 3D functions and 1080p full HD resolutions, but 3D functions cannot be perfectly interpreted with images. This function I think about how to give you a demonstration.

The NEC NP-CD3100H has a high lumen output and excellent contrast. It is a good home HD home theater and it's easy to install. The superior quality of the NEC NP-CD3100H in 2D quality allows you to enjoy movies and television at home. Of course, the 3D picture is also good, and the 3D picture will be brought to the next 3D picture to follow. The concise menu makes the adjustment of the projector easy and fast. It is suitable for people like me who just touch the projector. In general, I was very satisfied with the NEC NP-CD3100H and experienced it.

Incremental Encoder

Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
