Screen resolution overview:
Display resolution is the number of pixels displayed on the screen, generally expressed as (number of horizontal pixels × number of vertical pixels). The higher the resolution, the greater the number of pixels and the more precise the image being sensed. When the screen size is the same, the higher the resolution, the more detailed and delicate the display effect will be.
Screen resolution standard:
If different monitors use different resolutions and there is not a fixed ratio, then Without a complete resolution specification when shooting or producing, it can easily lead to the problem that the image cannot be restored in the best way. For this reason, some standards must be set.
4:3:
4:3 is the most common screen ratio, an ancient standard passed down from the television era. Before the rise of widescreen in modern times, most screen resolutions were based on this ratio. Standards suitable for this ratio are: VGA (640x480) SVGA (800x600) p>
16:10 is the common “wide screen” ratio, which once almost monopolized the market. Being replaced by 16:9. Standards suitable for this ratio are: WVGA (800x480) WSVGA (1024x600) WXGA (1280x800, 1366x768) WXGA+ (1440x900) WSXGA+ (1680x1050) WUXGA (1920x1200) WQXGA (2560x1600)
16:9
16:9 is mainly the ratio used by HD TVs. The commonly heard 720p and 1080p are both in this ratio. It is a screen format suitable for video viewing and office operations (accommodating two documents to be processed side by side) and gaming entertainment (wider field of view). The standards suitable for this ratio are: 720p (1280x720) 1080i (1920x1080) 1080p (1920x1080)
5:4
There is only one 5:4 Standard SXGA (1280x1024). It became popular in the later period, between 17 inches and 19 inches.
