In recent years, home high-definition projectors have been completely fired. The new brands are endless, dazzling, many of which are like real gold and silver like brand models, but there are also many fake and shoddy products. What kind of home HD projector is better? Xiao Bian talked about this experience and hope that everyone will not be cheated when buying.
Trap 1, do not deliberately pursue brightness
Brightness is one of the commonly used indicators for the purchase of home HD projectors, because once the brightness is not enough, the projected picture is easy to whiten, and can not meet the daily viewing needs during the day, so many consumers spend a lot of money for the purchase Projectors with a brightness of 2000, 3000, or even 5000 lumens need to know that this is not necessary.
The so-called extreme pole will be reversed. If the brightness of the projector is not a good thing, then the picture you see will be very dazzling, and the damage to the eyes will be very large for a long time. So how many home HD projectors are more reasonable in brightness? Generally 800-1500 ANSI lumens. Can be adjusted according to the size of the curtain.
According to common experience, the projection screen size and brightness are compared as follows:
80-100 inch screen requires 800 lumens brightness
100-120 inch screen requires 1000 lumens brightness
120 inches or more screen requires 1300 lumens or more
Trap II, standard resolution and compatible resolution
The standard resolution refers to the original resolution of the image projected by the projector, also called the real resolution and the physical resolution. The compatible resolution refers to the resolution of the input signal that the television allows, and it is not necessarily related to the screen display of the actual performance of the screen.
When the resolution of the input signal is greater than the physical resolution of the screen, the signal is compressed to the range that the screen can display. When the resolution of the input signal is less than the physical resolution of the screen, the interpolation algorithm can also be enlarged to the physical resolution of the screen. Size, but this is the image may not be clear.
It can be seen that choosing a home HD projector should look at the standard resolution rather than the compatible resolution. How much resolution should we have at this time? First 1080P, followed by 1280800.
Trap III. "High Dynamic Contrast"
Contrast refers to the measurement of the different brightness levels between the lightest and darkest blacks in the light and dark areas of an image. The larger the difference, the greater the contrast. The smaller the difference, the smaller the contrast.
With the concept of contrast becoming more and more popular, major projector manufacturers have listed the machine's contrast in the parameter sheet, but because of the previous standard, the contrast of the projector is quite confusing.
In general, manufacturers prefer to mark the ratio of the brightness of an all-white screen to a full-black screen because of its higher value and confusing nature. According to current technology, the ANSI contrast ratio of all recently produced LCD projectors is around 300:1, while the ANSI contrast ratio of DLP projectors is maintained at around 500:1. As for those contrast ratios that are 100000:1, the basic It can be viewed as a digital game without looking at anything.
Trap 4, do not be greedy "more"
Home projectors are new things that have only recently emerged. Many consumers are still not very familiar with them. Manufacturers also like to give them "multi-functional, high-performance" hats. In this regard, the author reminds that when buying homes, Before HD projectors, we must be clear about our own choice of use, not to be deceived by what ridiculous features.
