3. 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'.

4. 2160p = 3840 x 2160 - commonly known as 4K, UHD or Ultra HD resolution. It’s a very large display resolution and it’s found on high-end TVs and monitors. 2160p is called 4K because it offers four times the resolution of 1080p FHD or 'Full HD'.
