How to choose a projector for the living room?

I think a widescreen one is OK.

EPSON DM2 or W6 don't know if it will satisfy you, unless you are a person with a high quality of life, TW3000 and TW4000 will beckon you.

P's film is still quite clear on the projection.

The size of the inch depends on how far away your living room is viewed, and the price is different. Now you can buy a 1080P projection for about 1W blocks.

3. The projection effect is not good in airports and other places, and it is related to the light and the lumens of the projector.

The airport station is not a projection, it is LEDA 70-inch one can be installed in the living room of the home.

You can buy an electric curtain, good about 1000. Just choose Hitachi for projection.

The following parameters should be noted

1.Look at the light source technology: early halogen lamp, now the development of high-pressure mercury lamp + color wheel, but the life is very limited, the average life of 2000-4000h to change the bulb, the cost of 500-1500 yuan, divided into different types and components, the emerging micro investment are three-color LED, characterized by long life, 2-30,000h, and no need for color wheel, small power consumption, brightness household is also acceptable, with the progress of technology, can do about 200-1200LM, the first link below is LED light source technology, There is also a laser technology light source, which is basically composed of monochrome blue light + color wheel, three primary color technology and cost are too high, not suitable for home use, laser technology is also characterized by long life, no need to change the light source during the use period, and LED life is about the same, wide color gamut, high brightness, the second link below is laser technology projection;

LED light source technology 3 primary colors, colorless wheel, telephoto.

Pure laser light source + color wheel technology, ultra-short throw.

Technology and LCD technology: the imaging principle is different, the cost of a single LCD is low, it belongs to the entry level, and the current DLP technology is more widely used, and the technology is also very mature;

3.The brightness parameters of the light source directly affect the imaging effect, because it is reflected light imaging, so the environmental impact is very large, and the power consumption and efficiency of the light source bulb are related, generally speaking, the parameters of high lumens are much better, and the market is from hundreds to thousands of LM products, which are proportional to the price;

4.Contrast parameters: black and white field effect, brightness and ambient light have a great impact, it is generally recommended to do proper shading treatment like a movie theater, the effect is also good, the brightness can be reduced, and power consumption is saved, the use of metal gray curtain is also a common means to improve contrast, but there are gains and losses, loss of white field performance;

5.Operating system: At present, the basic development of Android system has become standard, and there is also a Windows system, which can install software, office, film and television and other applications.

8.Transmittance parameters: determine the distance and projection size, divided into telephoto and short focus, the transmittance ratio in: about 1 belongs to ultra-short throw, the lens can be projected from the curtain dozens of centimeters to project a 100-inch large screen, there are still many advantages.
