I believe everyone is not unfamiliar with this product, but many friends do not know the various parameters of the projector very well. Today we will explain the related issues about the resolution of the projector.
First of all, the resolution of the projector does not refer to the resolution of the signal that the projector can receive, but the physical resolution of their core optical machine. The core optical machine refers to DMD chip, LCD panel, LCOS panel, etc.
The resolution of the projector is expressed by multiplying the number of horizontal pixels by the number of vertical pixels in the screen. Below we will list the resolution and representation methods of common projectors:
SVGA refers to 800×600, which is generally the resolution used by economical projectors, which is not common now; XGA refers to 1024 x 768, which is generally used for mainstream business and education projectors, and is also used in some micro-projection home products; SXGA+ refers to 1400 x 1050, high-end projector mainly for high-end professional applications such as images.
480p refers to 852×480, which is generally used in low-end home projectors; 720p refers to 1280×720 or 1280×768, which is mainly used in mid-range home projectors, and many miniature home products also use this resolution; 1080p refers to 1920×1080 or 1920×1200, which is a mid-to-high-end home projector The resolution used by the projector; 4K resolution refers to 3840×2160, currently mainly used in high-end home projectors or engineering projectors.
Although the projector can usually receive signals of multiple resolutions, when the signal resolution is higher than the physical resolution of the projector, the picture details will be significantly lost. So even though some machine displays can support a certain resolution and can be compatible with the words of a certain resolution, the display resolution is still the resolution of its core optical machine.
