1440p is the shorthand name for a family of video display resolutions. The p stands for progressive scan, i.e. non-interlaced. The 1440 denotes a vertical resolution of 1440 pixels, double the vertical resolution of 720p.

In autumn 2006, Chi Mei Optoelectronics (CMO) announced a 47" 1440p LCD panel to be released in Q2 2007[1]; the panel was planned to finally debut at FPD International 2008 in a form on autostereoscopic 3D display. [2]

Support

1440p video mastered from 4:3 ratio content could be displayed with 1920×1440 or higher resolution such as QXGA or 2304×1440 with scaling, windowboxing, or pillarboxing. Widescreen 16:9 1440p requires 2560×1440 (WQHD) resolution, possible with WQXGA, 2560×1920, or higher resolution with letterboxing, scaling, or windowboxing. Apple's 27" iMac[3] and Dell's UltraSharp U2711[4] monitor are WQHD, thereby allowing 1440p widescreen. The HDMI 1.3 specification supports WQXGA, and hence widescreen 1440p.

Usage

In July 2018, 3.12% of gamers using Steam who opted in to analytics had a resolution of 2560×1440p, while 0.36% had a resolution of 3440×1440p [5]

  • 3120x1440p : LG G7, LG V40 ThinQ
  • 2960x1440p : Galaxy S9, S8, Galaxy Note 9, Note 8

  • 2560x1440p : Galaxy S7, S6, Galaxy Note 5, Note 4, Nokia 9, 8, Huawei Nexus 6P, Blackberry Priv, Pixel XL, LG G3

5120x1440 will be the newest 1440p monitor resolution, and has an aspect ratio of 32:9. Philips 499P9H is the first 32:9 1440p monitor to be announced; and it was in IFA 2018. 5120x1440p monitors are also expected to be announced by Samsung and LG.
