I believe you are no stranger to this projector, but you don't understand the problems of various parameters.
The resolution of a projector does not refer to the resolution of the signal that can be received, but to the physical resolution of their core light engine.
Core light engine: DMD chip, LCD panel, LCOS panel, etc.
Resolution is expressed by multiplying the number of horizontal pixels in the picture by the number of vertical pixels.
Here are some common resolutions and representations:
SVGA resolution: [800 600] is usually seen in budget projectors, but it is rare on the market today.
XGA resolution: [1024 768] is widely used in mainstream business and education fields, and is also suitable for some micro home projection products.
SXGA+ resolution: [1400 1050] is mainly aimed at high-end professional scenarios such as image processing, and is the first choice for advanced projection equipment.
480p resolution: [852 480] is mostly used in entry-level home projectors.
720p resolution: [1280 720 or 1280 768], mainly used in mid-grade home projection equipment, and also used in many micro home theaters.
1080p resolution: [1920 1080 or 1920 1200] is the standard configuration of mid-to-high-end home projection equipment.
4K resolution: [3840 2160] is currently mainly used in top home projection equipment and professional engineering projection equipment, providing the ultimate picture quality experience.
Projectors can usually receive signals of multiple resolutions, but when the signal resolution is higher than the physical resolution, there is a significant loss of picture detail.
Some machine displays can support a certain resolution, can be compatible with a certain resolution of the wording, and the resolution of its display is still the resolution of its core light engine.
Smart projectors want to ** live TV, as well as get more content resources, you can achieve it by installing a sofa butler.
