What is native resolution in projectors

Users' demand for home theater is getting stronger and stronger, and more and more families are equipped with projectors at home. After all, it is still very good to experience theater-level enjoyment at home. But this also confuses many white users who have just "entered into the pit" and don't know much about the projector's picture quality and resolution standards. What is the native resolution of the projector?
Take Vivid 813 as an example: 
Parameters for  Vivid 813
Native Resolution: 720p
Support Resolution: Maximum 1080p (see HD projector 1080p)
Contrast Ratio: 10000:1
Throw Ratio: 1.5:1
Brightness: 3000 Lumens (see portable projector 3000 lumens 1080P)
Projection Size: 20” – 180”

1. Resolution
Resolution is the primary factor affecting the image quality of a projector. What is the local resolution of the projector? At present, 1080P resolution is the more common resolution on the market, but in fact, the price of many machines marked with 1080P resolution varies. So why exactly lead to disparity in price gaps?First of all, if you want to reach 1080P physical resolution, its display chip must reach 0.47DMD and above, and 1080P below this standard are all "scratch balls".

2. Brightness
Brightness is an important factor affecting the viewing experience. Compared with a TV's backlight panel or self-luminous particles, a projector needs to project a light source onto other planes to form diffuse reflection. Compared with the direct light source, the reflected light source has a much milder impact on the eyes, but the loss of brightness is foreseeable, so the quality of the light source brightness is particularly important.

3. Color
Projector color is a prerequisite for us to enhance the viewing experience. Whether colors are accurate and true is a necessary factor for measuring picture quality. In the testing of projection equipment, the Rec.709 international standard color gamut is commonly used. This is the international standard used for high-definition televisions and the universal color gamut standard for the release of Blu-ray discs in cinemas.

We often say that 8bit can display 16 million colors, and the actual number of colors is 256 × 256 × 256. If it is increased to 10bit, it can render more than 1.07 billion colors, which means that it can present more types of colors and make the picture more colorful.In addition, the factors that affect picture quality actually include contrast, lens material, etc., but resolution, brightness, and color are undoubtedly very important and convenient for comparison. What is the local resolution of the projector? As a home projector, the resolution of the projector really plagues many "Little White" users, but as long as these three parameters are noted, it will be much more convenient when purchasing.
