question: If screen resolution of my phone is same as resolution used in most cinemas, how come movie isn't very bad and pixelated in cinema?
comment: Most movie projectors have 2K resolution, about the same as a "Full HD" TV set at 1920 & times;1080 pixels. This resolution is designed to match 20/20 vision when viewed at 3 screen heights which is roughly 1.5 screen diagonals. So, viewing your 5" phone from 7.5" away, or viewing a 50' cinema screen from 75' away will give you the same level of detail in the image.

  There are film industry specific arguments in the film vs. digital debate.
  
  Most digital cinema is displayed in 2K resolution, which is only a small amount more resolution than the consumer-oriented 1080p HD format.
   Section::::Reception.:United States and Canada.
   "The Wall Street Journal" referred to Apple's removal of the matte screen as one of Apple's worst design decisions.
  
  On July 26, 2010, the 24-inch and 30-inch Cinema Displays were replaced by a 27-inch model that supports up to 2560×1440 resolution. This model was sold for $999 USD.
  
  On July 20, 2011, the LED Cinema Display was discontinued, and replaced by the Apple Thunderbolt Display.
  
  Section::::Technical specifications.
   Despite the fact that today, virtually all global movie theaters have converted their screens to digital cinemas, many major motion pictures even as of November 2018 are shot on film. Christopher Nolan also released his latest film "Dunkirk" in IMAX, 70 mm, and 35 mm in selected theaters across the world.

  The DCI 4K standard has twice the horizontal and vertical resolution of DCI 2K (), with four times as many pixels overall.
  
  Digital movies made in 4K may be produced, scanned, or stored in a number of other resolutions depending on what storage aspect ratio is used. In the digital cinema production chain, a resolution of 4096 × 3112 is often used for acquiring "open gate" or anamorphic input material, a resolution based on the historical resolution of scanned Super 35 mm film.

   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. 
   Storaro feels in the future of cinema, films will be photographed in either high-definition video for small, intimate digital projection theaters, or in 65 mm for "big audience... large screen" films. In the cinematographer's opinion, as all films will be one of the two formats, he suggests a common aspect ratio compromise of 2.00:1 (mathematical average of 65 mm 2.20:1 and HD 1.78:1) be adopted for all films, 65 mm theatrical, HD theatrical and television.
   Reduction print
  
  Section::::motion picture film.
  
  A reduction print is a print of a large-size format film converted to a smaller size format (for example, a 70mm print converted to 35mm). Often this is necessary because not all theatres have a screen of the size required to show a film in large format, or indeed the projection equipment. This is especially true of some screens in multiplex theatres. In former days, it was true of the neighbourhood theatres located outside of downtown areas.

   Theaters began projecting movies at 4K resolution in 2011. Sony was offering 4K projectors as early as 2004. The first 4K home theater projector was released by Sony in 2012.
  
  Sony is one of the leading studios promoting UHDTV content, offering a little over 70 movie and television titles via digital download to a specialized player that stores and decodes the video. The large files (≈40GB), distributed through consumer broadband connections, raise concerns about data caps.
   The film was originally scheduled to be released on May 15, 2015, but on August 12, 2014, the release date was changed to July 24, 2015. In the United States and Canada, it was released in the Dolby Vision format in Dolby Cinema, which is the first ever for Sony. It was released in China on September 15, 2015.

   Though experiencing rapid price drops beginning in 2013 for viewing devices, the home cinema digital video projector market saw little expansion, with only a few manufacturers (only Sony ) offering limited 4K-capable lineups, with native 4K projectors commanding five-figure price tags well into 2015 before finally breaking the US$10,000 barrier. Critics state that at normal direct-view panel size and viewing distances, the extra pixels of 4K are redundant at the ability of normal human vision. Projection home cinemas, on the other hand, employ much larger screen sizes without necessarily increasing viewing distance to scale. JVC has used a technique known as "e-shift" to extrapolate extra pixels from 1080p sources to display 4K on screens through upscaling or from native 4K sources at a much lower price than native 4K projectors. This technology of non-native 4K entered its fourth generation for 2016. JVC used this same technology to provide 8K flight simulation for Boeing that met the limits of 20/25 visual acuity.
   Section::::Use of pixel aspect ratio.
  
  Pixel aspect ratio value is used mainly in digital video software, where motion pictures must be converted or reconditioned to use video systems other than the original. The video player software may use pixel aspect ratio to properly render digital video on screen. Video editing software uses pixel aspect ratio to properly scale and render a video into a new format.

  In other territories, Pixels was opened alongside Paper Towns, but bigger than the record of Pixels, it was released into July 26, 2015, behind the horror The Vatican Tapes, at the time, it became the most profitable film after Southpaw.

   BULLET::::- 35 mm film is scanned for release on DVD at 1080 or 2000 lines as of 2005.
  
  BULLET::::- The actual resolution of 35 mm camera original negatives is the subject of much debate. Measured resolutions of negative film have ranged from 25–200 LP/mm, which equates to a range of 325 lines for 2-perf, to (theoretically) over 2300 lines for 4-perf shot on T-Max 100. Kodak states that 35 mm film has the equivalent of 6K resolution according to a Senior Vice President of IMAX.

   With the introduction of LCD panels, the matte, anti-glare screen panels were retired, except for the 30" Cinema Display. Apple had already moved away from matte screens in its line of iMac desktop computers on August 7, 2007. Apple no longer offers any equipment with a matte, anti-glare screen after the 15" non-Retina MacBook Pro was discontinued in October 2013. This has caused concern among users who want matte screens for their particular area of work, particularly graphic designers, photographers and users who extensively view their screens. Matte screens, like matte-surface photographs, diffuse reflected light and so cannot provide for as deep blacks as glossy screens.

  Although the twin projectors are capable of displaying the 7,500:1 contrast ratio defined by the DCI fixed luminance gamma function for movies not graded with Dolby Vision, the projectors are limited to 5,000:1 contrast ratio. The Hollywood studios have graded over 100 films directly on Dolby Cinema projectors, the creative team can then create content with contrast ratios of 1,000,000:1.

   To neutrally judge the accuracy and/or feasibility of these sources, please note that as the digital motion picture was invented years after the traditional motion picture, all video pictures targeted for standard definition television and compatible media, digital or otherwise, have (and must have) specifications compatible with standard definition television. Therefore, the pixel aspect ratio of digital video must be calculated from the specification of common traditional equipment rather than the specifications of digital video. Otherwise, any pixel aspect ratio that is calculated from a digital video source is only usable in certain cases for the same kind of video sources and cannot be considered/used as a general pixel aspect ratio of any standard definition television system.
