What does screen resolution mean?

  • 720p = 1280 x 720 – is usually known as HD or “HD Ready” resolution
  • 1080p = 1920 x 1080 – is usually known as FHD or “Full HD” resolution
  • 2K = 2048 x 1080 – this refers to displays that have a horizontal resolution of approximately 2000 pixels. Although it is close to 1080p, it is considered as a different resolution standard.
  • 1440p = 2560 x 1440 – commonly known as QHD or Quad HD resolution, and typically seen on gaming monitors and on high-end smartphones. 1440p is four times the resolution of 720p HD or “HD ready.”
  • 4K or 2160p = 3840 x 2160 – commonly known as 4K, UHD or Ultra HD resolution. It is a huge display resolution, and it is found on premium TVs and computer monitors. 2160p is called 4K because the width is close to 4000 pixels. In other words, it offers four times the pixels of 1080p FHD or “Full HD.”
  • 8K or 4320p = 7680 x 4320 – is known as 8K and it offers 16 times more pixels than the regular 1080p FHD or “Full HD” resolution.
