The following is a comparison of high-definition smartphone displays, containing information about their specific screen technology, resolution, size and pixel density.It is divided into three categories, containing smartphones with 720p, 1080p and 1440p displays.
QHD (Quad HD) or 1440p is a display resolution of 2560 × 1440 pixels. [ 13 ] [ 14 ] The name "QHD" reflects the fact that it has four times as many pixels as HD (720p). It is also sometimes called "WQHD" [ 15 ] [ 16 ] to distinguish it from qHD ( 960 × 540 ), otherwise it is technically redundant since the HD resolutions are all widescreen ...
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio).
Early 1440p computer displays became commonly available in 2010. Dell's UltraSharp U2711 monitor was released in 2010 as WQHD, with a 1440p widescreen. [1] The 27-inch Apple LED Cinema Display released in 2010 also had a native resolution of 2560 × 1440, as did the Apple Thunderbolt Display which was sold from July 2011 to June 2016.
2560×1080, 3440×1440 Used in some professional and gaming displays since the mid 2010s, roughly matches various anamorphic formats: 32:9 (3. 5:1) 3840×1080, 5120×1440 Used in some high-end displays since 2017. 4:1 17280×4320 Used in some advertisement displays. †
Samsung first demonstrated its 105-inch UN105S9W curved OLED TV at CES 2014.While Samsung lists the UN105S9W as a 4K UHD TV, it actually has native resolution of 5120 × 2160 (a 64∶27 or ≈21∶9 aspect ratio) which classifies it as a 5K display due to the horizontal pixel count of ≈5,000.
Both models use a wider 19:9 aspect ratio, with the Pixel 4 using a 5.7-inch (140 mm) 1080p panel, and the 4 XL using a 6.3-inch (160 mm) 1440p panel. Unlike the Pixel 3 XL, the Pixel 4 XL's display does not contain a cutout, or notch. [18] The Pixel 4 includes dual rear-facing cameras located within a raised square module.
