1440p Video Resolution
1440p is the shortened name for a 2,560 x 1,440 resolution at a 16:9 aspect ratio. It is sometimes referred to as Quad HD because it offers four times the resolution of a 1,280 x 720 HD display. WQHD is another descriptor for the 1440p resolution.
As the TV industry considered its next jump up in resolution beyond 1080p, 1440p was one possibility. Ultimately, though, 1440p was bypassed in favor of Ultra HD or 4K, which offers at least a 3,840 x 2,160 resolution, or four times that of 1080p.
Even though 1440p will not be a major player in the world of HDTVs and home theater projectors, it still has a place in the consumer electronics industry right now - namely, in laptops, computer monitors and smartphones. A growing number of computer monitors are sporting a 1440p resolution and becoming a popular choice amongst gamers.
In the world of smartphones, the increase in resolution to 1440p offers a huge step up in pixel density at the smaller screen sizes. In 2014, a number of manufacturers plan to introduce smartphones with a 1440p resolution, including LG, Samsung, Vivo, and Oppo (which is known in America primarily for its disc players but is a major player in smartphones elsewhere in the world).
