For people who like to watch movies, the big screen experience is the first thing I want to pursue, and at present, I can only rely on projection to achieve more than 100 inches at a lower cost, plus I'm renting out a room, giving preference to a portable 4k projector to facilitate my move afterward. The projector's visual and auditory enhancement is also attractive enough for me, which is often referred to as "immersive home theater".

Advantages and disadvantages of home projectors compared to TVs

The projection screen is bigger and the immersive viewing experience is better

Buy a TV the size is recommended to buy a large budget range not to buy a small, and 98-inch smart TV, even the cheapest need more than 10,000 yuan, this price can buy a high configuration projector, and projector projection size can reach 100-180 inches, a large screen to bring the viewing effect will also be better. What’s better a projector or a tv?

Diffuse reflection imaging, low blue light more eye protection

TVs are generally LED backlight, the light source is directly on our eyes, a long time on the eye damage is still quite large, which is why many children who like to watch TV are early to wear glasses. Compared to television, the projector uses the principle of diffuse reflection imaging, to avoid the blue light and screen flash on the human eye injury, but it is not to say that there is no harm, just harm, and television than smaller.

Small size, lightweight, and more convenient to move

Projectors compared to television, projector size specifications are small, lightweight, where you want to put it, and easy to move.

In the end, buy a projector or TV, the key still depends on the actual needs of individuals, if you have high requirements for picture quality, brightness, and size requirements are not high, then you can choose the TV; if you like the large size, the picture quality requirements are not too high, it is recommended to choose the projector. In fact, as long as the budget is high enough, the projector is a better choice, because the brightness, and picture quality problems, in some of the higher configuration of the projector, is basically not a problem.

How to pick the right projector for you?

Look at the parameters, determine the type of projector, define your needs, and choose a specific model.

How to see the parameters of the projector?

Display chip

3DLP DLP LCoS 3LCD LCD

The display chip that relates to the projection image quality is the key to understanding, now on the market display chip LCD, 3LCD, DLP, 3DLP, and LCoS are the kinds of. Leaving aside the millions of 3DLP chips used in cinemas, the most common home projectors on the market today are LCD, 3LCD, and DLP these chips.

But the LCD display chip is now basically in the semi-elimination stage, with poor color, and the response speed is not, the thousand-dollar projector is still using the LCD display chip.

In addition, in 3LCD and DLP two chips, DLP chip color, and response speed is better than 3LCD, and can be said to be the most preferable choice of home projector chip.

Light source

laser LED bulb

Projectors used in the light source, mainly bulbs, LED, and laser these three.

The advantage of using a lamp projector is that the projection screen brightness is high enough and cheap. But the disadvantage is also obvious: the life of the lamp is relatively short.

The advantage of LED light sources is that the projection picture has good color saturation, long service life, and a cheaper and more comprehensive price, so most projectors on the market are currently using LED light sources. The disadvantage is that the brightness may be slightly inferior. The use of a laser light source projector, both the brightness of the picture, color saturation, and service life than the lamp and LED is better. But the price is also placed where do not consider the budget can enter.

Brightness

Although the higher the brightness of the projector the higher the price, we are not the brighter the better when it comes to choosing a projector. After all, there is a fundamental difference between the needs of a theater and the needs of a family, which is the same as buying a light bulb: a 100-watt bulb in a 10-square-meter room will only blind you! The projector's picture is too bright, but it will cause eye discomfort.

In terms of personal experience, daytime viewing using real lumens in the 2000 ANSI or more, pull the curtains to experience the effect enough; night projection 100-inch screen to see the real lumens 1000 ANSI lumens between not only good picture display effect, while the eye comfort is also the best.

It is important to note that there is a pit here in the brightness! The unit of brightness has ANSI lumens, lumens of these two. It does not seem to be a big difference, but the actual is not at all in an order of magnitude! Usually, "ANSI lumens" is only one-third of "lumens"! So when buying and selling we have to recognize the ANSI lumens!

Resolution and chip

①Resolution: 4K＞1080p＞720p

②Chip: 0.33DMD＞0.47DMD＞0.66DMD＞1.38DMD

The resolution of the projector directly determines the clarity of the picture, and the higher the resolution of the projector chosen, the better naturally. However, not all models are able to display the high resolution, but must also be combined with the actual chip, because the DMD chip is the higher resolution that the projector can accept.

• 0.33 DMD chip can accommodate 720p resolution;
• 0.47 DMD chip can accommodate 1080p resolution;
• 0.66DMD chip accommodates 2k resolution;
• The 1.38DMD chip accommodates 4K resolution.

Projection Ratio

The projection ratio is the ratio of the distance projected by the projector to the width of the projected image. The smaller the projection ratio, the larger the size that can be projected at a smaller distance. Simply put, a projector with a small projection ratio (less than 1) is suitable for homes with a small area; a large projection ratio (projection ratio = 1.2) is suitable for homes with a medium or large area.

Projector must see additional features

Keystone correction and automatic screen entry

Trapezoid correction is a very necessary function, normal use is difficult to ensure that the projector is facing the wall, especially in the past home decoration did not set aside wires, so basically will side projection use. And so the projected picture will become trapezoidal, there is a trapezoidal correction function, which is to correct the trapezoidal picture into a rectangular, one to achieve the desired effect of viewing.

One of the best four-way correction functions, you can give priority to choose.

The automatic entry screen can directly say goodbye to the tedious manual debugging. After the power is on automatically identify the curtain area, align the projector with the screen and the projection screen and the edge of the curtain are easily aligned.

Operating system

Preferably Android, the Android system has better compatibility with third-party apps and sources, and will provide a better experience when using them, with fewer restrictions on sources and apps. How to connect Android to a projector wireless?

Dolby sound

The great experience of watching movies in the cinema is not only because of the large screen but also the superb sound! Watching a big movie when you want to immerse yourself in it or need projector audio support.

Motion compensation

As the motion compensation function is inserted in the high-speed movement of the picture to fill the frame, will make the picture play more smoothly. Watching racing blockbusters as well as sports competitions is more sensory, to avoid the movement of the picture dragging and shaking situation!

Conclusion

The home projector compared to the TV, advantages of the projector are still a lot, With a comprehensive comparison of brightness, resolution, operating system, functional experience, and other aspects of comprehensive consideration, the projector is more worth getting.
