At the end of last year, following the footsteps of valued friends, they also spent more than 10,000 sets of introductory home theaters. Over the past year, they continued to watch movies with 200+ movies. It was a must-have for the family and sent them away. Time is a rare weapon. The effect of the entry may not catch up to one-tenth or one-tenth of that of a real movie theater. However, compared to a 60-70-inch TV, the projector is motionless with a 100-inch screen. Compared to going to a movie theater, a home theater wins when you want to see it, and you want to stop and stop, stand, look, lay, see, and what posture you want to use. No more annoying sounds linger in your ears, nor does the "body scent" or "foot scent" that makes people smell disgusting appear around you. When I'm in my free time, I'm going to get a cool life with my HD action movie. Life is changing and it's all colorful.
The initial impression of the projected landlord should begin more than a decade ago. The cinema is not as popular as it is now. The Internet is still dialing the phone, watching movies (including small movies), and most of all it is going to the video hall in the streets, the impression is a bit of scale. The most used video hall is like Sony's three-gun projector. According to the current vision, it really is to see a person's shadow and hear a ring, but in the 21-inch TV is a huge screen, entertainment facilities are scarce in the era, is already This is a very happy thing. As for the films that are sown, in the era when the big sisters are not yet on stage, they are basically based on Hong Kong, Taiwanese movies and third-grade films.
Pulled a bit far, or let us come back and continue to test
At present, 4K projectors are generally more expensive, and 4K sources are scarce. 1080P projections are undoubtedly the best choice at this stage. According to the imaging principle of projection, it is mainly divided into two camps: LCD and DLP. Both have their own advantages in terms of color, contrast, and dynamic display. (How to choose the projector that is suitable for you, you can refer to other originals of value-friends). DLP entry-level projection, worthy friends are familiar with BenQ's 1070 and 1070 + (of course, such as Optoma, Acer does not do more to introduce), the introduction of the three-chip LCD to Epson's 5XXX-based, When the landlord bought last year, the first one is afraid of the rainbow eyes, of course, the 5350 price is very good, so he invested Epson's arms. Today, with the opportunity of Zhang Da Ma's test, NEC has the honour to test today’s protagonist CD3100H and feel the advantages of DLP imaging. Thanks again for the support and trust of the next worth buying and NEC.
Listed below are the main parameters of the two projectors that are worthy of high exposure and have a similar price to the CD3100H (data taken from the network). It can be seen from the table that the overall performance is very close as an entry-level product.

Positive entry:
▼ The overall industrialization of packaging style, of course, the top of the box is indisputable, everybody wants to see the 朕 worth the stickers
â–¼ For the current situation of domestic express delivery, it is indeed very helpless, there are few items that can be completely intact, NEC's packaging is still to force, there is room for activities in the carton, otherwise it will be hanging, but the service of SF Still good, sent it at 9:00 pm, saying that if there is a direct connection with the problem, it should already be a photo forensics in the store.
â–¼ The internal fixation method does not use the traditional foam, but simply uses a bubble bag, 360 degree comprehensive protection. The first time to see this kind of packaging method is Jingdong global purchase of milk powder, the protective performance is still very good.
â–¼ Appearance design adopts the all-white simple style. The surface of the shell is frosted to effectively reduce surface reflection and effectively avoid fingerprint collection. The appearance of the product is square, and it is also suitable for business place applications. With the further increase in projector brightness, the boundaries between business and home become more and more blurred
â–¼ Look at the size of the Epson TW5350 contrast, length and width slightly larger than 5350, slightly less than the thickness of 5350, compared to 5350's sleek, 3100H significantly more masculine
▼ Left and right sides of the large area of ​​the cooling window, is not aware of so many cooling vents will not speed up the intrusion of dust, the whole machine up and down several warranty seals, itchy to want to take a look and see is impossible to do
â–¼ lens protection cover, no TW5350 host comes with the convenience, fast, if there is electric lens cover is not even better, please ignore my daydreaming, the right hand side is the remote control receiving window, try the next, remote control Without directionality, you can operate in any direction.
â–¼ Embedded lens, do not understand, do not make more reviews
â–¼ The back interface is quite comprehensive, and it is basically compatible with the input of computers, set-top boxes, etc. in recent years, and has increased the output of a separate monitor. Some interfaces are used as a little extra for home use.
â–¼ To steal the interface configuration diagram lazily on the instructions, you can see a variety of interfaces readily available, my mother did not have to worry about I could not even projection.
â–¼ look at the interface with the 5350 back compared to more than 5350 network interface, read the instructions again, LAN port is used to control the computer-side projection, after the connection, the computer to download dedicated software, you can directly in the computer Operate the projector above.
â–¼ Projector top adjustment button and status indicator, the Chinese character of the Bank is indeed more comfortable than Hai Tao's English, poor domestic prices, when can we meet the world, when can we not waste a few dollars in order to save the province? The mind went to the sea.
â–¼ The remote control logo is very clear, it is easy to get started, the shape is slightly common, and each time you see a bunch of movie remote control
â–¼ Lens zoom and focus adjustment, full manual, damping is also good, no TW5350 comes with a handle to adjust smoothly
â–¼ The bottom is relatively flat with a lot of 5350, the installation of the rack will save a lot, the 5350's several mounting holes are very curious, and later it is still their own DIY under the barely loaded up
â–¼ Accessories are relatively simple, from left to right VGA cable, power cord, remote control and warranty card, electronic manual (CD-ROM), there is no paper manual at random, personal feel for accessories since it is mainly for home users, then this VGA cable Replaced by HDMI cable to a more practical point, the general home is already difficult to find the VGA interface device, the manual or retain the paper, and now the computer is rarely installed CD-ROM drive, that is, there is no paper on the computer to see The convenience
Prove that I am the next, a separate room, called the audio and video room seems to be a little over, the room did not make any changes, originally empty, will use it. This year I had an accident with two treasures. I was born in the past ten days. This room is the children's room in Erbao. It is about 20 square meters. I can use four or five years before the kindergarten in Erbao. After the year 4K should be almost universal, move the first floor, engage in a larger 4K projection
â–¼ The monitor has no chance to play dual screen, double projection to the first experience, in order to have a more intuitive experience, a computer dual output, dual screen display the same content, the conditions are simple, the seat is still the last single Audiovisual seat for a long time butt hurt that Zhang, always wanted to buy a first class sofa back, the old could not bear to throw, contradiction ah
â–¼ Originally still afraid that did not read the instructions to get uncertain, the actual boot will be able to see the friendly Chinese, direct language to select Simplified Chinese, behind the settings are all default settings, the mode selected energy
â–¼ A total of four main menus, there are several sub-menus under the main apple list, the entire Chinese menu, or very easy to understand, the general customer can directly select the default options can be, like the demolition can study the study to see the changes in the parameters of the projection The change is not great.
â–¼ This is a curtain shot, you can clearly see that, like this brightness below, the projector still meets the projection needs, this shot is a small distance, followed by a large, interesting down 
TW5350 because of the use of a period of time, probably spent 400-500 hours, the brightness is estimated to be attenuated, of course, the brightness of the two also have a difference of 800 lumens, from the above figure is still a bit obvious (left hand side CD3100H)
â–¼ is really a gun sharpening, connected to the line is still looking for how to set up dual screen
â–¼ DLP's common problem, rainbow effect, most people do not see, under the lens will be very obvious, especially when the background is white, the performance is more prominent below. The left side is 3100H, the right side is TW5350, the picture may not look very clear, the text description under it, the 3100H font is more clear, the TW5350's font is slightly weak, the same text, 5350's font looks like it is 3100H display The feeling of bold fonts, clearer fonts are suitable for presentations such as business PPT. Unsure of his own eyes, it is best to go to the store first experience, bought back to find a cup of rainbow eyes. (Real shot text is shown later)
â–¼ As can be seen from the following, the background color of 3100H display is more correct, and the display effect of 5350 is more warm
â–¼ Look at the color performance (left 3100H right TW5350, not repeat behind the instructions), because it is the cause of the screen shot, the actual projection display, the entire screen brightness is very uniform (explained below), the overall look, the 3100H color performance is more pure, In particular, the 3100H win over the entire black background, benefiting from the brightness of 800 lumens higher than 5350, the actual display on the left is obviously brighter on the right (for the color temperature I browse the next manual, the actual can be adjusted, not much to expand here )
â–¼ Looking at the performance of the same two below the Zhang, screen shot looking at the difference between the original picture is larger, the actual display effect is still very good to restore the original image, the color performance above 3100H gives people feel more transparent point, color performance The above is relatively cold, and the performance of the TW5350 is not as strong. The blue sky and grassland are very obvious. The blue sky performance of the TW5350 even wants to add a polarizer. Like small fresh or full of gorgeous looking completely like personal preference
â–¼ 4K video screen, 3100H for the details of the performance slightly better than the TW5350, before really not under the 4K video, the same projector, PT under 1080P, Blu-ray original disk, 4K video source below the gap is still very clear , It seems that at this stage, a good video source is more reliable and economical than buying a higher-level projector.
â–¼ The internal temperature of the projector is still very high, pay attention to the installation distance, maintain good ventilation and heat dissipation
â–¼ Lamp position temperature
â–¼ 3100H for the cooling control of the machine is also good, basically concentrated in the light bulb this, other parts of the temperature rise is not obvious
With a pylon mount, the projector is usually just above or below the head. Every time the TW5350 is used to watch a movie, when the movie has no background sound, the top of the screen is like a fly flying on it (fantastic fan sound). From the data measured below, we can see that the noise of the CD3100H is much lower than that of the TW5350. Below the normal mode of the TW5350, the average noise is 90. The noise of the CD3100H below the energy-saving mode is slightly better than that of the TW5350. The gap below the normal mode is too large.
â–¼ CD3100H adopts the energy-saving mode and noise performance under normal mode
â–¼ TW5350 Noise Performance Under ECC Mode and Normal Mode
3.2, projection installation
Because the pylons have already been installed, the process of punching and mounting the pylons has been saved. It is still difficult to find people to engage in it, and it is necessary to count them again. It is prone to size errors.
â–¼ NEC3100H can use this bracket directly, unlike the TW5350, can not be installed normally, I am still fixed in the hole above the floor to calculate
â–¼ Projection that you want to temporarily think about, no wiring, no wiring, no wiring
â–¼ It looks like the angular projector looks good.
Before purchasing the projector, first measure the depth of the house, determine the size of the curtain, and see if the projection you want to buy matches the room. The width of my room is 4m7. The width of the projector and the shelf will be removed. With a 120-inch multi-point appearance, the 133-inch picture frame left a circle in white. When installing, try to pay attention to the projector as horizontally as possible. Although the current projector basically provides trapezoidal correction, the angle difference is too much, and the adjustment of the image quality is also affected.
â–¼ The official projection installation data, the same screen size, CD3100H projection distance slightly larger than the TW5350
Take the more common 120 inch as an example: the minimum projection distance is 3985 mm, the size of the projector: 324 mm (width) × 88 mm (height) × 250 mm (deep), and the thickness of the bracket and the reserved space is calculated as 100 mm. 120-inch cast, no matter if it is a living room or a separate room, the width should be at least 4335 mm
3.3, NP CD3100H HD picture projection testâ–¼ Take a look at the performance of the CD3100H static image, limited by the equipment and personal level issues, the actual projection is significantly better than the screen effect, the image display is closer to the original image, the color performance is relatively soft, the projection effect can fully meet the home users Claim.

â–¼ Let's take a look at the screenshot performance of the 4K video, the color performance is very eye-catching, no noticeable tailing during playback
â–¼ Fury 1080P video screen camera, camera is not to force, the dynamic picture is not very good to capture, a dozen inside only picked such two, black, dark details are better than TW5350.
â–¼ Individuals do not feel bad about 3D, TW5350 spent nearly a year, did not go to buy 3D glasses, TV has just bought when you read the one or two, it is not for public beta to buy 3D glasses , ring-yang Blu-ray 3D video screen, this picture just tells everyone that CD3100H is indeed with 3D function
â–¼ Finally, look at the brightness of the projection under the condition of pulling out the curtain during the day (shooting time is around 9:50 AM). Under the support of high brightness, the projection screen can also be seen, slightly white, and slightly pulled during the day It is entirely feasible that point curtains reduce direct light instead of television.
â–¼ The curtains pull the performance of half the projection
â–¼ Finally, look at the effect of the CD3100H text display, the text display is very clear, compared to the LCD is more suitable for business applications, PPT and other demonstrations.
â–¼ Continue to zoom in and take a look at the pixels. Thanks to the 0.65-inch DMD display chip with a square reflective pixel mirror, the text and image edges are dramatically reduced. Interested in understanding the impact of different DMDs on imaging can be seen. Friends of the original
Talking about the impact of DMD's size and arrangement on projection effects recently, smart micro-investments suddenly became hot, and various products of various brands were crowdfunded. As the most central part of the projection, display technology is undoubtedly the most concerned about everyone, in the current projection market, LCD technology in addition to Epson and other brands still insisting that DLP... 118720 swq01 Limited to the shooting equipment, personal level, this time the public test to write here, what is wrong and want to understand the article is not in the comments area, please leave a message, I will reply as soon as possible
After a period of use, CD3100H, there are many remarkable places for picture display and video playback, the standard trapezoidal correction function greatly simplifies the projector's adjustment difficulty, the six-color wheel is added to the projection color The performance is more natural and bright, and the high brightness of 3,000 lumens also expands the application of the projector. Taking into account brand awareness, product performance, and the price that the e-Commerce 4000+ can buy, the NEC CD3100H is a very promising projector.
Advantages: high brightness, correct color reproduction, simple operation, easy to use
Disadvantages: In a quiet environment, the sound of the fan is still a bit large, and the projection distance is long, which will affect the width of some rooms (depth) is insufficient for the customer's choice
Tips: Audio and display product evaluation is limited by the use of scenes, shooting equipment, the author's level and insights, it is difficult to truly and objectively restore the actual use of the product, many times the evaluation will be too many individuals Subjective ideas, suggesting that the value of such needs of friends or listen to the truth, seeing as the standard, to the physical store after the personal experience, in making choices.
