In 2016, IMAX announced the release of films in Ultra-WideScreen 3.6 format, [6] [failed verification] with an aspect ratio of 18:5 (36:10). [7] A year later, Samsung and Phillips announced 'super ultra-wide displays', with aspect ratio of 32:9, for "iMax-style cinematic viewing". [ 8 ]
There are other, non-standard display resolutions with 1080 lines whose aspect ratios fall between the usual 16∶9 and the ultra-wide 64∶27, e.g. 18∶9, 18.5∶9, 19∶9 and 19.5∶9. They are mostly used in smartphones or phablets and do not have established names, but may be subsumed under the umbrella term ultra-wide (full) HD .
Although 3840 × 2160 is both a 4K resolution and a 2160p resolution, these terms cannot always be used interchangeably since not all 4K resolutions are 2160 pixels tall, and not all 2160p resolutions are ≈4000 pixels wide. However, some companies have begun using the term "4K" to describe devices with support for a 2160p resolution, even if ...
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.
The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.
1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...
