What does 1280*800 resolution mean?

1280*800 resolution means that the number of horizontal pixels is 1280 and the number of vertical pixels is 800; 1280*800 is a high-definition resolution. High-definition resolution (HD) refers to images or videos with a vertical resolution greater than or equal to 720, also known as high-definition images or high-definition videos. The sizes are generally "1280×720" and "1920×1080".

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The resolution of 1280*800 means that the number of horizontal pixels is 1280 and the number of vertical pixels is 800. 1280*800 is HD resolution.

High Definition (HD) refers to images or videos with a vertical resolution greater than or equal to 720, also known as high-definition images or high-definition videos, with average size It's 1280×720 and 1920×1080. "HD" stands for "high definition".

Common HD resolutions: 720p (1280×720, non-interlaced, field frequency 24, 30 or 60), 1080i (1920×1080, interlaced, field frequency 60), 1080p (1920×1080 , non-interlaced, field frequency is 24 or 30), a1080, a720, 816p. The first three are key indicators used to mark the resolution of high-definition movies. Among them, the i and p followed by the number are the abbreviations of Interlace scan and Progressive scan respectively, and the number reflects the vertical resolution of high-definition video.

For example, 720p refers to 1280*720 progressive scanning, and 1080i refers to 1920*1080 interlaced scanning. This is a convention that the horizontal resolution of the signal source is Methods to implement abbreviated naming rules. Reaching a resolution above 720p is the entry threshold for high-definition signal sources. The 720p standard is also called the HD standard, and 1080i/1080p is called the Full HD (Full HD) standard.

Extended knowledge:

The higher the resolution, the greater the number of pixels, and the more precise the sensed image is. When the screen size is the same, the higher the resolution, the more detailed and delicate the display effect will be.

Resolution is the precision of the screen image, which refers to the number of pixels that the monitor can display. Usually, the number of pixels in each row is multiplied by the number of pixels in each column, for example:

• The resolution is 1024×768, which means the monitor can display 768 rows and 1024 columns, and a total of 786432 pixels can be displayed;

• The resolution is 640×480, which means the monitor can display 480 Rows, 640 columns, a total of 307,200 pixels can be displayed.

Since the points, lines and surfaces on the screen are all composed of pixels, the more pixels the monitor can display, the more detailed the picture will be, and the information that can be displayed in the same screen area There are also more, so resolution is one of the very important performance indicators.
