1440p

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]

1080p

1080p (1920×1080 px; also known as Full HD or FHD and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as full HD, to contrast 1080p with 720p resolution screens.

1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movies, consumer-grade televisions and projectors, computer monitors and video game consoles. Small camcorders, smartphones and digital cameras can capture still and moving images in 1080p resolution.

2K resolution

2K resolution is a generic term for display devices or content having horizontal resolution of approximately 2,000 pixels. Digital Cinema Initiatives (DCI) defines 2K resolution standard as 2048×1080.In the movie projection industry, DCI is the dominant standard for 2K output.

Comparison of high-definition smartphone displays

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 "p-display" nomenclature used in this article refers to the number of pixels displayed across the width of a given phone's screen. Earlier phones with lower than 720p (lower than HD ready resolution) are not included in this listing. The lists below are dynamic lists and may be sorted into alphabetical order by clicking on the "sort icons" at the top of the first column.

Dashcam

A dashcam, dashboard camera, car DVR, driving recorder, or event data recorder (EDR) is an onboard camera that continuously records the view through a vehicle's front windscreen and sometimes rear or other windows. Some dashcams include a camera to record the interior of the car in 360 degrees (inside camera, usually in a ball form) and can automatically send pictures and video (using 4G).

EDRs and some dashcams also record acceleration/deceleration (g-force), speed, steering angle, GPS data, etc.

A wide-angle (130, 170° or more) front camera may be attached to the interior windscreen, to the rear-view mirror (clip on), or to the top of the dashboard, by suction cup or adhesive-tape mount. A rear camera is usually mounted in the rear window or in the registration plate, with a RCA Video output to the display monitor / screen.

The resolution will determine the overall quality of the video. Full HD or 1080p (1920×1080) is standard for Dash HD cams. Front cameras may have 1080p, 1296p, 1440p, or higher definition for a front camera and 720p for a back camera and include f/1.8 aperture and night vision mode.

Dashcams can provide video evidence in the event of a road accident. When parked, dashcams can capture video and picture evidence if vandalism is detected (360° parking monitor) and send it to the owner (usually employing 4G).

LG G3

The LG G3 is an Android smartphone developed by LG Electronics as part of the LG G series. First released in South Korea on May 28, 2014, it is a successor to 2013's LG G2. Inheriting design elements from the G2, such as its thin screen bezels and rear-mounted power and volume buttons, the G3 is distinguished primarily by being the first smartphone from a major manufacturer to incorporate a 1440p display, and its inclusion of an infrared hybrid autofocus system for its camera. LG also touted the device's plastic "metallic skin"—designed to give the device a higher quality appearance, and a "simpler" user interface with an integrated intelligent personal assistant system.

The G3 received mostly positive reviews, with critics praising the overall appearance, performance, and software of the device. LG was panned for using a faux metallic plastic instead of an actual metal material for its exterior. The 1440p display was also considered bleeding edge technology, citing poor brightness levels and the use of artificial sharpening. 10 million units of the G3 were sold in the device's first 11 months on sale.

LG G5

The LG G5 is an Android smartphone developed by LG Electronics as part of the LG G series. It was announced during Mobile World Congress as the successor to the 2015 LG G4. The G5 is distinguished from its predecessors by its aluminum chassis and a focus on modularity; the lower housing which contains the battery can be slid from the bottom of the device, and replaced by alternative add-on modules that provide additional functions, such as a camera grip or a high-fidelity audio module with DAC. A lower-spec variation, dubbed the LG G5 SE, is sold in selected markets.

The G5 received mixed reviews; while the device's design was praised for its shift to a metal construction while maintaining the ability to remove its battery, the modular accessory system was panned for its limited use cases and inability to perform hot swapping. LG's software was also panned for the quality of its customizations.

All Galaxy Note models also include software features that are oriented towards the stylus and the devices' large screens, such as note-taking and digital scrapbooking apps, and split-screen multitasking.

The Galaxy Note smartphones have been considered the first commercially successful examples of "phablets"—a class of smartphone with large screens that are intended to straddle the functionality of a traditional tablet with that of a phone. Samsung sold over 50 million Galaxy Note devices between September 2011 and October 2013. 10 million units of the Galaxy Note 3 have been sold within its first 2 months, 30 million were of the Note II, while the original Galaxy Note sold around 10 million units worldwide.

Superphone

Superphone is a loose term used to describe any smartphone with high-end features that distinguishes them from basic (low-end) smartphones. The term was introduced when Google launched the Nexus One.It implies high-end functionality beyond the basic criteria for a smartphone, such as the ability to be more tailored to a specific user's needs. A Superphone usually incorporates state of the art technology, innovations in hardware, and newer refined software. For example, having the latest SoC chip made from OEMs such as Qualcomm or Intel. A superphone could also imply a certain set of physical characteristics that is unique, unusual, innovative, and not regularly seen in smartphones; an example of this are the edge-to-edge "bezel-less" displays found in higher-end smartphones such as the Samsung Galaxy S8 or the Essential Phone.

An appropriate example of a Superphone is the LG G Flex 2. The body is curved horizontally, making it less likely to break when bent, for example when one sits on the phone by accident. The back of the G Flex 2 is coated with a material that 'self-heals' within minutes when scratched. The Moto Z can also be considered an example of a Superphone for its innovative "Moto Mods", a set of individual modules which can be magnetically attached on the back to greatly extend the functionality of the phone.

Many flagship smartphones from various OEMs (Samsung, LG, HTC) can be considered to be Superphones, as the term flagship refers to the OEMs most high-end offering. Both terms can be used simultaneously to convey the same meaning.

Plausible criteria for Superphones in 2017 include:

Minimum of 1080p (Full-HD) display, 1440p (Quad-HD) displays are more preferable. 4K-screens are anticipated.

Screen display larger than 5-inches (125 mm) (may overlap with phablet).

Screen display features minimal bezels, adopting the 'bezel-less' form factor

USB-C port, instead of the older Micro-USB 2.0

The addition of a fingerprint or iris scanner for extra security

Hardware is built out of high-end durable materials

A dual camera system, either for increasing the field of view, the optical zoom, and/or to enhance the color reproduction of the image

Supports NFC.

Supports Qi Wireless Charging.

Supports Quick Charging.

Ability to replace system software and user-interface of the phone using 3rd party software.

Ability to add certain modules to extend the functionality of the phone

Multi-core processor and dedicated 3D-graphics, minimum of 1.5 GHz.

At least 4GB of RAM.

Large capacity battery, larger than 3000mAh.

High-speed internet 100Mbit/s WWAN capabilities or higher.

Has Hi-Fi audio capabilities built into the phone.
