â–¶Select the projector, these points should pay attention to:
1. Commercial Projector or Home Projector
Many people mistakenly believe that commercial projectors and home projectors do not make any difference, but in fact, in terms of parameters, or performance, the two are very different.
Commercial projectors are often not very high resolution, basically 720P or lower, and the ratio is often 4: 3 such a narrow screen; brightness is far more than the average home projector, can reach 3,000 lumens, daytime lights are No pressure to use; color reproduction and contrast will be slightly worse than home projection.
Home projectors will pay more attention to resolution, and 720P and 1080P are all mainstream. Of course, the trend is definitely going in the 4K direction. With a brightness of 1000-2000 lumens, it will pay more attention to the performance of color and contrast.
2. Resolution
At present, 4K resolution has become the standard for TVs on the market, but on projectors, 1080P and even 720P are common. 4K is a rare product, and the price is basically more than 50,000.
In addition to the higher cost of the 4K-level projection chip, the most important thing is that the distance to view the projection is often far away. The difference between the 4K and the 1080P is not so great (however, the 4K product positioning is high-end, the color brightness and so on are all higher than The general projector is much better. So the living room chooses 1080P resolution, and the bedroom selection of 720P is enough.
Of course, the most important thing to note is that the resolution mentioned here refers to the physical resolution. Many projectors claim to support 4K. That is purely to support 4K video decoding. The resolution displayed is only 720P.
3 projection technology
When we choose a projector, we often see technologies like 3LCD, DLP, etc. that are advertised. This is actually the way they realize the projection.
There are currently three mainstream projection technologies: 3LCD, DLP, and LCOS.
3LCD: A projection technology developed by Seiko Epson in Japan. The light emitted from the light bulb decomposes the three primary colors of light and realizes imaging through the respective liquid crystal panels. The advantage is that the color has a good expression, but the brightness and 3D performance are slightly weak.
DLP: a projection technology developed by Texas Instruments, the light source through the color wheel after the refraction on the digital micromirror components, after the control signal through the control panel will be emitted to the projection screen; the advantage is that the brightness has a good performance, However, the color performance is weak and even rainbow patterns appear on the low-end products.
LCOS: The basic principle is similar to 3LCD, but it uses the LCOS panel to control the light projection. Compared with the other two technologies, the performance is balanced in all aspects. The disadvantage is that the cost is higher and the volume is larger. Currently, it is mainly Sony and JVC. The two are in use. Sony names its own LCOS technology as SRXD.
From the current models on the market, small and portable models and Taiwan-based brands basically use DLP technology, while Japanese brands use 3LCD technology, while high-end models use LCOS or SRXD. technology.
4. Lamp life
Many people will confuse the problem of lamp life when selecting a projector. In general, lamp life is about 2000 to 5,000 hours. Normal use for 3 years is not a problem. And after three years, the cost of changing a light bulb will not be very high, so this fact does not need to be entangled. The products of the regular manufacturers are more secure.
In addition to conventional light bulbs, many brands will claim to use LEDs and laser light sources. The advantage of LED light sources is their small size and long life. Therefore, portable devices will use more light, but there will still be a large gap between brightness and light bulbs. The laser light source is used in high-end products, high brightness and color purity, long life.
5. Built-in system
Now many brands are focusing on the projection of non-screen TVs or built-in smart systems. In fact, this is a combination of TV boxes and projections. It will naturally be more convenient to use. If not, then an external TV box is enough, at least not. It is necessary to choose a certain section because of this function. It is important to pay attention to the performance of the projection itself.
▶ Don’t regret when these projections are finished:
BenQ MS3081+ Projector Although this BenQ MS3081+ projector is primarily targeted for commercial use, it uses a six-color wheel technology, so its color performance does not lose the home model, plus a brightness of 3200 lumens and a contrast ratio of 13,000:1. Support 3D, as the main home pressure completely no pressure, the only regret is that the resolution is only 800 x 600, suitable for budget is limited, or the living room is relatively small home use.
