Nowadays, projectors are becoming more and more popular in multimedia, advertising, and exhibition halls, and interactive ground projection through projectors can also bring people the enjoyment of large screen visual experience. However, the field of projector use is expanding today, many users who buy projectors are still confused about the selection standards of image quality, and do not understand how to buy projectors to see how much resolution is appropriate. In this blog, we are on the popular science resolution and image quality related purchase knowledge.
Image Quality Related Purchase Knowledge
Principle
Resolution, also known as resolution, resolution, and resolution power, is used to judge the precision of an image. The projector using DLP technology, that is, the digital light processing projector, uses the digital micromirror device DMD chip as an imaging device, the size of this chip is equivalent to a matchbox, but there are millions of “small mirrors” on it, the light source enters the interior of the projector, shines on the mirror, and finally reflects on the screen into the image, which is the basic principle of DLP projector imaging. The resolution of the projector is also based on this principle.
HD
High Definition is a word we are relatively familiar with at present. HD was first proposed in the field of radio and television, the earliest by the American Society of Motion Picture and Television Engineers (SMPTE) and other authorities to develop relevant standards, video surveillance field is also widely used in the radio and television standards. The Definition of “High definition” is 720p, 1080i, and 1080p three standard forms, and 1080P has another name – Full High Definition. About HD standards, there are two internationally recognized: video vertical resolution of more than 720p or 1080i; The video width ratio is 16:9.
SD
Standard Definition is a video format with a physical resolution below 720p.
UHD
Ultra High-Definition, that’s what we’re focusing on today. According to newly approved information from the International Telecommunication Union, The official name of 4K resolution (3,840 × 2,160 pixels) has been changed to Ultra HD(Ultra High Definition). The name also applies to “8K resolution (7680×4320 pixels)”.
Picture Quality
When it comes to resolution, we all know that it refers to the clarity of the picture, and many people’s understandings is limited to this. SGA, VGA, 1080P, 4K, etc., why are there so many resolution standards? Does higher resolution mean better application results? Projector resolution hidden knowledge? How much resolution is appropriate to choose a projector? When we choose UHD or HD projectors, we can buy them according to consumption capacity, but if you want to choose a projector that can also be viewed outdoors, there is a great demand for picture quality. In my opinion, the best outdoor projector can be selected from Nebula Mars 3 Outdoor Projector, Vankyo Performance V700W, Nebula Capsule II, etc. which has perfect projection capability and can enjoy excellent picture quality outdoors.
Advantage
The projector is very space-saving and easy to carry, and for those who rent outside, it is also convenient to move. Compared with TV, intelligent projection can achieve a larger screen, more portable, and less expensive. In addition, home projectors are more eye-friendly than TVS. The imaging principle of the projector is different from that of the TV, the light source is reflected to form diffuse reflection light, and the picture quality is stable without flicker problems, which can alleviate visual fatigue. Moreover, the projector can achieve a super large screen, suitable for watching movies, and you can have a good immersion-watching experience at home.
Conclusion
Home projectors can boost our sense of well-being, allowing us to return home and enjoy the theater-like feeling, feast on color, and enjoy time spent with family.
