How to distinguish LCD screen resolution
720P, 1280P, 2K, 4K, 8K, HD... There are so many resolution names on the market! Today, let's take a look at what they are and how to remember them! (Quick method at the bottom) First, you only need to remember these two: VGA and HD, and the rest is simple.
VGA: Resolution is 640*480. It's still used in many small screens, like around 3.5 inches in industrial applications. Large screens rarely use it now.
HD is also called 720P. The resolution is 1280*720, entry-level HD, still used in older small-screen devices. After understanding these two, the rest is much simpler. Much smaller than VGA is QVGA, with a resolution of 320*240, commonly used within 3.5 inches. Slightly smaller than VGA is HVGA, with a resolution of 480*320, commonly used in 4.3-inch and 5-inch screens. Slightly higher than VGA is FVGA, with a resolution of 854*480, more common in portrait mode, and with a 16:9 aspect ratio. Next is HD. Slightly higher than HD is FHD, which is the common 1080P, with a resolution of 1920*1080. Older monitors, laptops, and TVs mostly use this resolution, and the industry still uses it. The mainstream standard, significantly higher than HD, is called QHD, commonly known as 2K, with a resolution of 2560*1440. This is currently the mainstream for consumer products, offering a very detailed picture. Moving up the spectrum is UHD, also called 4K, with a resolution of 3840*2160. It's primarily used for large screens of 55 inches and above, though smaller screens also have it, but at a very high price, belonging to the high-end series. The current top-tier resolution is 8K, 7680*4320, which is already professional-grade, and resources for this are very scarce. If you've read this far, it means you're genuinely interested. Let's simplify: look only at the first number of the resolution:
1000+ (1280/1920) is HD/FHD
2000+ (2560) is 2K
3000+ (3840) is 4K
7000+ (7680) is 8K
