There are many factors that affect the clarity of the projector, and most of the small partners may think that the higher the brightness, the clearer it is, in fact, the brightness is only part of the clarity that affects the clarity of the projector, and other such as resolution, chip, contrast, projection environment, etc. have a certain relationship.
First of all, the resolution, the general projector is mainly 720P, 1080P-based, although there are 4K, but not the price is too high, or pseudo-4K, not in the choice of most consumers (of course, there is money please feel free ~), usually, 1080P projector picture quality is enough to meet the needs of daily use.
The second is brightness, because some merchants have a virtual brightness situation, so we must polish our eyes to see clearly, the brightness is often more than several thousand lumens, the price is very grounded, it may only be the brightness of the light source, not the standard ANSI lumens. Usually not during the day to watch if 1000-2000 lumens is enough to use, if there is a need for this, it is recommended to be above 2000 lumens to ensure the viewing effect.
There is also a chip also determines the projector's picture display effect, the current chip technology is mainly 3LCD, DLP, LCOS these 3 mainly, 3LCD compared to DLP, color performance is better, but the brightness is general, and DLP imaging is sharp, brightness performance is excellent, but the color performance is slightly weaker, some are prone to rainbow phenomenon. LCOS is more balanced in all aspects, the color and brightness are outstanding, but the price is not good, beyond the budget of many people.
However, compared to chip technology, chip size is also crucial. The DMD chip size used in general DLP projection technology has 0.33 inches, 0.47 inches, 0.65 inches and other specifications; the 3LCD chip size has 0.55 inches, 0.59 inches, 0.63 inches and other specifications. The larger the chip size, the better the screen display, but the price is also more expensive.
Let's talk about contrast, in general, the brightness is appropriate, the higher the contrast, the more color levels displayed on the screen, and the more vivid the picture. Contrast is the ratio of black to white in a picture, that is, the gradient from black to white. The larger the ratio, the more gradients are layered from black to white, resulting in a richer color expression.
Finally, there is the projection environment, including the projection distance, the brightness of the environment, and the size of the projection image. In general, the larger the projection imaging, the higher the lumen loss, resulting in a decrease in sharpness, and the projection ratio is also very important, if the room is too small to meet the projection requirements of 100 inches, it will also affect the clarity. The second is the brightness of the environment, and the clarity will also be reduced in the bright environment during the day, which will affect the viewing experience.
These are some of the main factors that affect the clarity of the projector, although not all, but if these conditions are met, daily use is no longer a problem.
