There are many ways to enhance happiness, sometimes a clean and tidy room after a big cleaning; sometimes it is a small object that is not expensive but full of experience; sometimes it is a potted plant that is not usually noticed grows small shoots. Xiao Ying will talk about the household goods.
Good household items can make your home warmer and more comfortable, and you even want to stay at home without going out.
For many office workers, the happiest time of the day is to come home at night, take a beautiful shower, make a cup of tea, and then get into the bed, turn on the projection brush drama and watch a movie.
Bedroom + projection, the ultimate happiness of the home, it does not have to be fixed like the TV, and it occupies a lot of space. Advances in technology have made it very portable for today's projectors, which is very friendly for the bedroom, you can directly cast it on the white wall or ceiling, and then lie down and watch TV or play games, and feel the small blessings of life.
However, the premise of all this is to choose a good projector, bad products certainly can not bring excellent experience, and many friends just do not understand how to choose a projector, what parameters to pay attention to? Xiao Ying will come to pick a pickpocket for everyone:
In general, consumers buying projectors mainly focus on portability and imaging effects.
Portable is very easy to choose, beautiful and small, everyone chooses according to personal preferences, the important thing is that the imaging effect is this piece, there are several key parameters that need special attention.
To expand on the words, there are mainly brightness, resolution, projection ratio and other aspects.
Brightness determines whether you can see the picture clearly during the day, lumens as the brightness indicator of the projector, when purchasing, you must see clearly what the "ANSI lumens" value is. In general, indoors with better lighting, corresponding to the projector 1000-1500 ANSI lumens are more suitable.
After the brightness is selected, it is the resolution. The higher the resolution, the clearer the quality of the projection and the better the viewing experience. The resolution everyone will see, just pay attention to distinguish between standard resolution and compatible resolution.
The standard resolution is the resolution of the final output of the projector, which is the clearest picture effect you can see. Compatible resolution is the resolution that the projector supports decoding, for example, a projector standard resolution is 1080P, compatible resolution 2K, 4K, that is to say, it can decode 2K, 4K movies, but the resolution of the broadcast is still 1080P.
Therefore, the compatible resolution is useless to blow no matter how crazy, and the final picture clarity still depends on the standard resolution, the higher the better!
Brightness and resolution are determined, and finally there is the projection ratio, which determines how large you can see in a limited area.
Projection ratio refers to the ratio of projection distance to the width of the picture, here we need to explain, we usually call the length of the projection screen as the width, width as the height, so do not misunderstand.
The projection ratio of ordinary projectors is usually between 1.5-1.9, and when the projection ratio is less than 1, we usually call it a short-throw lens, and when the projection ratio is less than 0.6, we usually call it an ultra-short-throw lens. For example, if your bedroom has a bed-to-wall distance of three meters and you want to see a 100-inch frame, the projector's throw ratio is recommended to be below 1.35:1.
The last sentence summarizes: buy a projector to see the degree of portability, and the second mainly looks at the brightness, resolution, and projection ratio.
