Needless to use - basic household projectors

In 1989, at the age of four, I went to a video hall for the first time in kindergarten to learn the projector for the first time.

In 1997, when Hong Kong returned and celebrated with the whole country, in order to bring the distance between the mainland people and the people of Hong Kong closer in this great day, I think I need to have more understanding of Hong Kong, so I once again entered the video hall to watch. Hong Kong Life Film Learned and learned about the people of Hong Kong. This time, I suddenly discovered that the projector with the three large bulbs in my four-year-old memory became a very small machine with only one light bulb.

Later, with the advent of high-definition era and uncoded blockbusters, the popularity of computers allowed us to watch videos without going to the video hall anymore. A group of people in the dormitory always watched a large international movie around a 14-inch notebook. At that time, I Just thinking, if there is a high-definition projector to see how big the film is how cool.

In 2009, Optoma launched the first 1080p projector HD20. The first time home projectors reached 10,000 yuan, while the price of 42-inch 1080P LCD TVs was also around 10,000 yuan. A historic pace is the most critical step for projectors to enter the home sector on a large scale.

Subsequently, BenQ, acer and other projector brands have also launched their own million home projectors in high-definition, from 2009 to the present, the market for high-definition home projectors has been continuously expanding, the number of models has continued to increase, prices have begun year by year Declined, now, the price of a 1080P HD projector has been lowered to 4,000 yuan.

Looking at the more beautiful teacher, how can I not have a high-definition projector, so I decided to use my experience of playing with the projector in the past few years to write a guide for the purchase of a home-use high-definition projector.

The core type of projector

LCD projection

This type of projector is my first projector, its projection method is very simple, that is, through the optical amplification principle, the image of a LCD screen inside the body is magnified and projected, the main components are divided into LCD screen, driver board , Light bulbs, optical lens components, chassis, etc., its structure is simple, easy assembly, projector prices in previous years is still relatively high, many people use Ma Yun family to buy a projector DIY kit self-assembled projector is based on this The principle, the price according to the resolution of the LCD screen from a few hundred to 3,000 range, large body, low resolution, poor image quality, brightness is not enough, in short, in addition to relatively cheap prices, are basically shortcomings, now on the market Has been phased out.

DLP projector

DLP is the abbreviation of "Digital Light Processing", which is digital light processing, that is to say that this technology first digitally processes the image signal and then projects the light. It is a digital micromirror device (DMD) developed by TI (Texas Instruments) to complete visual digital information display technology. Specifically, DLP projection technology uses digital micromirrors (DMDs) as the primary key processing element to implement digital optical processing.

DMD chip size is different, the small 0.45 inches, a larger 0.65 inches, with the camera's photosensitive element, the larger the area the better the imaging effect.

3LCD projection

The 3LCD method decomposes light emitted from a light bulb into light of R (red), G (green), and B (blue) (three primary colors of light) and transmits the light through the respective liquid crystal panels (HTPS method). Shapes and movements. Since these three primary colors are often projected, light can be used effectively and bright and clear images can be produced. The 3LCD projector has bright, natural and soft images. Because three LCDs are used to display colors, images that do not harm the eyes can be reproduced. The 3LCD mode does not appear as a rainbow-like pattern called "color decomposition," which allows people to enjoy images with peace of mind for a long time.

Now buy a projector, LCD projection will not be considered, 3LCD color performance is more beautiful, reducibility is good, but for some movies more black and white field of the picture is slightly worse. DLP's machine has a high contrast, but the relative color is not as bright. The difference in power consumption between the two is not very large, and it can be selected according to its own needs for color.

Recommended before the taboo

Before making a formal recommended model, I used my experience to say that I had to buy a few taboos for home projectors.

1; Choose ultra-short focal models carefully. Before I sea scouring a BenQ W1080ST ultra-short focal projector, the overall quality is nothing to say, but ultra-short focus makes me a headache, my previous article has also been written, because there is no embedding, the projector is placed In the middle of the living room, drag a long line on the ground. The premise of an ultra-short-focus projector suitable for home use is that you have pre-embedded lines in advance and are using ceilings. The advantage of this is that you don't need to bury very long HDMI cables. W1080ST can project a 120-inch large screen at a distance of about 1 meter. If you don't bury the line, you can't stand such a big picture in the living room. If you live in a large living room, you can only sit in the middle and the position is extremely embarrassing.

2; careful selection of micro-cast. Micro-projection is a recently-emerged ultra-mini projector with a built-in TV box function. It is inexpensive and many people use it as a home projector. However, I don't recommend it. Micro-projection is ok, and it is a home projector. No, first, the physical resolution of micro-projection is generally only 720P, and secondly, its brightness is quite low. Using LED as a light source, the color reproduction degree is also very poor, and it is not suitable as a home projector.

3: Choose high lumen machines carefully. High lumen projector Here I refer to projectors above 3500 lumens. The brightness of such projectors is too high and the maintenance cost of the bulbs is relatively high. At the same time, these machines are mostly commercial or industrial projectors, and their energy consumption is also too high. High brightness has a greater impact on vision in our indoor viewing.

Recommended Brand

For models below RMB 10,000, the recommended brands are based on BenQ, Optoma, and acer. Epson's projectors are also good, but there are only a few cost-effective products below RMB 10,000. If you are willing to use 4K projectors, Tyrant, Epson is preferred.

BenQ series

BenQ Projection has a relatively large amount of power in recent years, and its product models and product lines are also increasing. Currently, it has the largest market share of home projectors below 10,000 yuan. The family projector series is divided into W Series and I Series, and the I Series is Projector with TV box, and W series is subdivided into W and WP, ​​wp belongs to the wireless signal input projector.


W1070+ is an upgraded version of the hot W1070, 1080P resolution, brightness increased to 2200 lumens, support for 3D, bulbs have a life of more than 4,000 hours, cut replacement costs are not high, the interface is comprehensive, the new version is equipped with a remote control with backlight , easy to operate.

The I700 is actually a TV box version of the W1070+. On the basis of maintaining the W1070+ parameters, the TV box has been added. It is worth mentioning that the BenQ TV box has a powerful application market and can easily install various video apps. The source of the program is richer than other television boxes that have implemented new regulations for broadcasting and television.


The I720jd is a customized version of JD.com, which is an upgraded version of the I700 from the model point of view. It is the latest color standard series projector from the series. Its image quality has reached the professional-grade standard color gamut, with a solid color system. Wheels, and passed the US ISFccc certification, the color and the picture at the same time at night with the TV, at the same time, the body speaker power upgrade to 20W, eliminating the need for additional speaker spending, the lens has up and down displacement function, and have around Trapezoidal correction enables side-shooting.


The W2000 is also a new machine that belongs to the color calibration series. It conforms to the Rec.709 color standard and is certified by the American ISFccc. It has a six-speed six-section full-color wheel with a rich interface. The main parameters are basically the same as the I700, but the details are more exquisite and are the latest. W series leader models. It is recommended as the first choice for the 8,000-yuan budget.


WP2010 is a wireless series belonging to W2000. It is equipped with a wireless HDMI input module, and supports up to 4 channels of signal input. It is suitable for users with multiple signal sources. The specific parameters I had before related to the sun list.

Optoma Series

Optoma as the first brand to pull the HD projector into the million level, in recent years, the power is relatively insufficient, and some follow-up powerless meaning, but the projector is not a TV, a good number of upgrades a year Edition, the basic model is a small update every two years, so currently on the market for home HD projector Optoma still has several remarkable products.

This is a projector with 3200 lumens. It can also watch normal daytime. The contrast ratio is as high as 22,000:1. It supports full-format 3D, up and down 40-degree trapezoidal correction, projection 100-inch shortest distance 3.28 meters, the price is lower than 5000, is super Cost-effective models.


Belonging to the upgraded version of 536, the basic parameters and appearance have maintained the level of 536, focusing on improving the picture quality, using Dynamic Black technology, 6-segment color wheel, with Gamma curve dynamic adjustment function, the screen more three-dimensional sense.

700 lumens machine, ultra-small, suitable for rental users, long-term home is not recommended, LED light source, long life.

Optoma's Jingdong proprietary models, I really can't help but I really can't blame the models I recommend. There are really not many recommendations.

ACER Series

Acer hottest projector, 3000 lumens, 10000:1 contrast ratio, support full format 3D, support 2D to 3D, 100 inches, minimum projection distance of 2.6 meters, 7000 hours lamp life, personal feel acer projector is the biggest feature is Special Founder, and suitable for storage.

Upgraded version of the 6510, lumens increased to 3400 lumens, belong to commercial and residential models, other technical parameters are basically consistent, suitable for business users.

Acer models sometimes I want to Tucao, this 3200 lumens, the above three in addition to lumens were 3000,3400,3200, the parameters are basically the same, subdivided this many models, I was drunk.

H7550ST is a model that competes with BenQ W1080ST, ultra-short focus, DTS sound, 100 inches only needs a distance of 1.5 meters, suitable for a living room narrower with large screen needs or lifting users, the most important feature is built-in Bluetooth, can be an external Bluetooth speaker Improve sound effects. Embedded hidden wireless slot (note, just slot), you can install wireless video player, the overall performance is more balanced, but the price is not as good as W1080ST.

3LCD on behalf of the model

The above models are recommended DLP models, since the beginning mentioned 3LCD models, not recommended is not complete, in recent years, 3LCD projector models gradually reduced, a little bit of the meaning of plasma and LCD TVs, because 3LCD I play Not too many, only one is recommended here.


Epson has been cultivating and relatively high-end markets in the projector field. Although there are many models of entry-level home console products, there is still a certain gap between the market share of BenQ and acer, and this model is Epson's most popular one. Models, using 3LCD technology, with 2200 lumens, support side-by-side 30 degree cast, support 2D to 3D, ECO mode lamp life of 7500 hours, the most important is that the registered members have three years warranty. For users who cannot tolerate the DLP projector's rainbow eye, this model is the first choice.

Conclusion

More than a dozen total recommended home projectors are available on the market. Except for the 720P, the ML750 is the physical resolution of 720P. The rest are 1080P resolution projectors with a lumen range of 2000-3400. The price ranges from 4000-9999. Ranging from the most concentrated in the price of 4500-7000, suitable for families with projection requirements of the economic needs, but also pay attention to the projector's price there is a certain gap between online and offline, online shopping mall is not necessarily cheaper than the line, it is recommended that everyone More contrast.

Do not ask why I do not recommend the recent comparison of a 1080P micro-projection, 4999 buy LED projector, almost crazy
