65-462: The Galaxy A50 has a 6.4" FHD+ (2340 x 1080) 60 Hz Super AMOLED Infinity-U display, with an 19.5:9 aspect ratio. It is powered by an Octa-core, 4x2.3 GHz ARM Cortex-A73 and 4x1.7 GHz ARM Cortex-A53, 64-bit, 10 nm CPU and a Mali-G72 MP3 GPU . The phone itself measures 158.5 x 74.7 x 7.7mm. It comes with a 4000 mAh battery. The A50 is sold in 4GB/6GB RAM and 64GB/128GB internal storage configurations, both of which can be expanded via

130-400: A MicroSD card up to 512GB. The A50 has an optical (under-screen) fingerprint sensor and facial recognition features used for biometrics. The Samsung Galaxy A50 comes with triple rear camera array consisting of a 25MP, f1.7, Sony Exmor IMX576 wide camera, an 8MP f2.2 ultra-wide camera, and a 5MP f2.2 depth sensor camera. It also comes with a 25MP front-facing camera . While the hardware

195-428: A computer monitor . Certain combinations of width and height are standardized (e.g. by VESA ) and typically given a name and an initialism which is descriptive of its dimensions. The graphics display resolution is also known as the display mode or the video mode, although these terms usually include further specifications such as the image refresh rate and the color depth . The resolution itself only indicates

260-592: A 16:9 aspect ratio and is exactly four times as many pixels as the 1600 × 900 HD+ resolution, and is therefore referred to as "QHD+" (Quad HD+). It has also been referred to as simply "QHD" and some companies. The first products announced to use this resolution were the 2013 HP Envy 14 TouchSmart Ultrabook and the 13.3-inch Samsung Ativ Q . The resolution 3440 × 1440 is equivalent to QHD ( 2560 × 1440 ) extended in width by 34%, giving it an aspect ratio of 43:18 (2.3 8 :1, or 21.5:9; commonly marketed as simply "21:9"). The first monitor to support this resolution

325-462: A 16:9 aspect ratio is often referred to as "900p". FHD ( Full HD ) is the resolution 1920 × 1080 used by the 1080p and 1080i HDTV video formats. It has a 16:9 aspect ratio and 2,073,600 total pixels, i.e. very close to 2 megapixels, and is exactly 50% larger than 720p HD ( 1280 × 720 ) in each dimension for a total of 2.25 times as many pixels. When using interlacing , the uncompressed bandwidth requirements are similar to those of 720p at

390-400: A 16:9 format with 240, 360, 480 (SD), 720, 1080 (HD), 1440, 2160 (4K) or 4320 (8K) lines. While the monikers for those resolutions originally all used a letter prefix with "HD" for the multiplier, and possibly a "+" suffix for intermediate or taller formats, the newer, larger formats tend to be used with "K" notation for thousands of pixels of horizontal resolution, but may be disambiguated by

455-654: A 27.84-inch 158   PPI 4K IPS monitor for medical purposes launched by Innolux in November 2010. In October 2011 Toshiba announced the REGZA 55x3, which is claimed to be the first 4K glasses-free 3D TV. DisplayPort supports 3840 × 2160 at 30   Hz in version 1.1 and added support for up to 75   Hz in version 1.2 (2009) and 120   Hz in version 1.3 (2014), while HDMI added support for 3840 × 2160 at 30   Hz in version 1.4 (2009) and 60   Hz in version 2.0 (2013). When support for 4K at 60   Hz

520-510: A 3:2 aspect ratio. By 2021, Huawei also offers a monitor display offering this aspect ratio, targeted towards professional uses. All standard HD resolutions share a 16∶9 aspect ratio, although some derived resolutions with smaller or larger ratios also exist, e.g. 4∶3 and 64∶27, respectively. Most of the narrower resolutions are only used for storing, not for displaying videos, while the wider resolutions are often available as physical displays. YouTube, for instance, recommends users upload videos in

585-606: A 47-inch 1440p LCD panel to be released in Q2 2007; the panel was planned to finally debut at FPD International 2008 in a form of autostereoscopic 3D display . As of the end of 2013, monitors with this resolution were becoming more common. The 27-inch version of the Apple Cinema Display monitor introduced in July 2010 has a native resolution of 2560 × 1440 , as did its successor, the 27-inch Apple Thunderbolt Display . The resolution

650-420: A 4:3 display). The 4:3 aspect ratio was common in older television cathode ray tube (CRT) displays, which were not easily adaptable to a wider aspect ratio. When good quality alternate technologies (i.e., liquid crystal displays (LCDs) and plasma displays ) became more available and less costly, around the year 2000, the common computer displays and entertainment products moved to a wider aspect ratio, first to

715-494: A detector element (a pixel sensor) is sensitive to electromagnetic radiation at any one time, is called instantaneous field of view or IFOV. A measure of the spatial resolution of a remote sensing imaging system, it is often expressed as dimensions of visible ground area, for some known sensor altitude . Single pixel IFOV is closely related to concept of resolved pixel size , ground resolved distance , ground sample distance and modulation transfer function . In astronomy ,

780-404: A minimum resolution for devices to qualify for the certification. However, few screens have been built that use this resolution natively. Most employ 16:9 panels with 768 lines instead ( WXGA ), which resulted in odd numbers of pixels per line, i.e. 1365 ⁠ 1 / 3 ⁠ are rounded to 1360, 1364, 1366 or even 1376, the next multiple of 16. The HD+ resolution of 1600 × 900 pixels in

845-579: A multiple of 960 pixels. The next bigger resolution from 1920 × 1080 in vertical direction is 1920 × 1200 (16∶10), which is hence called FHD+ by some producers, but is elsewhere known as WUXGA , the wider variant of 1600 × 1200 UXGA . DCI 2K is a standardized format established by the Digital Cinema Initiatives consortium in 2005 for 2K video projection. This format has a resolution of 2048 × 1080 (2.2 megapixels) with an aspect ratio of 256∶135 (1.8 962 ) or roughly "17∶9". This

910-434: A multiplication sign (e.g. "1920×1080"), which represent the width and height in pixels. Since most screens have a landscape format to accommodate the human field of view , the first number for the width (in columns) is larger than the second for the height (in lines), and this conventionally holds true for handheld devices that are predominatly or even exclusively used in portrait orientation. The graphics display resolution

975-520: A separate signal for each half over the connection, splitting the data between two timing controllers. Newer timing controllers became available in 2014, and after mid-2014 new 4K monitors such as the Asus PB287Q no longer rely on MST tiling technique to achieve 4K at 60   Hz, instead, using the standard SST (Single-Stream Transport) approach. In 2015, Sony announced the Xperia Z5 Premium ,

1040-539: A system qualifier that includes "HD", e.g. "8K UHD" instead of just "8K". nHD (ninth HD, not "nano HD") is a display resolution of 640 × 360 pixels, which is exactly one-ninth of a Full HD (1080p) frame and one-quarter of an HD (720p) frame. Notably, it is neither "nFHD" nor 426 × 240 which would be about ninth of "HD" resolution. Pixel doubling (vertically and horizontally) nHD frames will form one 720p frame and pixel tripling nHD frames will form one 1080p frame. One drawback of this resolution regarding encoding

1105-426: A widescreen aspect ratio. The first monitor to support this resolution was the 37.5-inch LG 38UC99-W. Other vendors followed, with Dell U3818DW, HP Z38c, and Acer XR382CQK. This resolution has been referred to as UW4K , WQHD+ , UWQHD+ or QHD+ , though no single name is agreed upon. The resolution 3840 × 2160 , sometimes referred to as 4K UHD or 4K ×  2K , has a 16:9 aspect ratio and 8,294,400 pixels. It

1170-506: Is a display resolution of 2560 × 1440 pixels. The name "QHD" reflects the fact that it has four times as many pixels as HD (720p). It is also sometimes called "WQHD" to distinguish it from qHD ( 960 × 540 ), otherwise it is technically redundant since the HD resolutions are all widescreen which the added 'W' empasizes. This resolution was under consideration by the ATSC in the late 1980s to become

1235-665: Is a display resolution of 960 × 540 pixels, which is exactly one-quarter of a Full HD (1080p) frame, in a 16:9 aspect ratio. Notably, it is neither "qFHD" nor 640 × 360 which would be quarter of "HD" resolution (720p). Some of the few tabletop TVs to use this as its native resolution from around 2005 were the Sony XEL-1 and the Sharp Aquos P50 . Sharp marketed its ED TV sets with this resolution as PAL optimal . Similar to DVGA , this resolution became popular for high-end smartphone displays in early 2011. Mobile phones including

1300-517: Is a ratio of lengths. For example, binoculars with a 5.8 degree (angular) field of view might be advertised as having a (linear) field of view of 102 mm per meter. As long as the FOV is less than about 10 degrees or so, the following approximation formulas allow one to convert between linear and angular field of view. Let A {\displaystyle A} be the angular field of view in degrees. Let M {\displaystyle M} be

1365-406: Is a simple multiple of the recommended software/virtual resolutions in order to show finer details; marketing terms for this include " Retina display ". The favored aspect ratio of mass-market display industry products has changed gradually from 4:3, then to 16:10, then to 16:9, and has now changed to 18:9 for smartphones . The 4:3 aspect ratio generally reflects older products, especially

1430-582: Is also used in portable devices. In September 2012, Samsung announced the Series 9 WQHD laptop with a 13-inch 2560 × 1440 display. In August 2013, LG announced a 5.5-inch QHD smartphone display, which was used in the LG G3 . In October 2013 Vivo announced a smartphone with a 2560 × 1440 display. Other phone manufacturers followed in 2014, such as Samsung with the Galaxy Note 4 , and Google and Motorola with

1495-417: Is capable of taking 4K video, it is not accessible by normal means (or by using the included camera app). It can be accessed using third party apps . The Samsung Galaxy A50 ships with One UI 1.1, based on Android 9.0 (Pie) . A stable update to Android 10 and One UI 2.0 was released at the beginning of April 2020. Features include Bixby , Google Assistant and Samsung Pay . An update to One UI 2.5

1560-629: Is double the size of Full HD ( 1920 × 1080 ) in both dimensions for a total of four times as many pixels, and triple the size of HD ( 1280 × 720 ) in both dimensions for a total of nine times as many pixels. It is the lowest common multiple of the HDTV resolutions. 3840 × 2160 was chosen as the resolution of the UHDTV1 format defined in SMPTE ST 2036-1, as well as the 4K UHDTV system defined in ITU-R BT.2020 and

1625-467: Is exactly 2 times the width and ⁠1 + 1 / 2 ⁠ times the height of 4:3 VGA ( 640 × 480 ), which shares its aspect ratio and 480 line count with NTSC . HD, therefore, has exactly 3 times as many pixels as VGA, i.e. almost 1 megapixel . In the mid-2000s, when the digital HD technology and standard debuted on the market, this type of resolution was often referred to by the branded name " HD ready " or "HDr" for short, which had specified it as

1690-597: Is exactly double the size of 2560 × 1080 in both dimensions, for a total of four times as many pixels. The first displays to support this resolution were 105-inch televisions, the LG 105UC9 and the Samsung UN105S9W. In December 2017, LG announced a 34-inch 5120 × 2160 monitor, the 34WK95U, and in January 2021 the 40-inch 40WP95C. LG refers to this resolution as "5K2K WUHD". Field of view The field of view ( FOV )

1755-422: Is influenced by the aspect ratio, which is the ratio of the width to the height of the display. The aspect ratio determines how the image is scaled and stretched or cropped to fit the screen. The most common aspect ratios for graphics displays are 4:3 , 16:10 (equal to 8:5), 16:9 , and " 21:9 ". The aspect ratio also affects the perceived size of objects on the screen. The native screen resolution together with

1820-490: Is more for lower resolutions such as nHD. To avoid storing the eight lines of padded pixels, some people prefer to encode video at 624 × 352 , which only has one stored padded line. When such video streams are either encoded from HD frames or played back on HD displays in full-screen mode (either 720p or 1080p) they are scaled by non-integer scale factors. True nHD frames on the other hand has integer scale factors, for example Nokia 808 PureView which has an nHD display. qHD

1885-494: Is referred to simply as HD, as is evident from derived terms like qHD ( quarter ) and nHD ( ninth ), which have a half and a third of the lines and columns of their common base 1920 × 1080 , respectively, whereas QHD ( quadruple ) has double the dimensions of 1280 × 720 instead. When set in relation to higher resolutions, 1920 × 1080 is also referred to as 2K because it has roughly 2000 pixels of horizontal resolution. This naming convention usually – but not always – assumes

1950-401: Is that the number of lines is not an even multiple of 16, which is a common macroblock size for video codecs . Video frames encoded with 16 × 16 pixel macroblocks would be padded to 640 × 368 and the added pixels would be cropped away at playback. H.264 codecs have this padding and cropping ability built-in as standard. The same is true for qHD and 1080p but the relative amount of padding

2015-399: Is the angular extent of the observable world that is seen at any given moment. In the case of optical instruments or sensors, it is a solid angle through which a detector is sensitive to electromagnetic radiation . It is further relevant in photography . In the context of human and primate vision, the term "field of view" is typically only used in the sense of a restriction to what

2080-453: Is the focal length , here the sensor size and f {\displaystyle f} are in the same unit of length, FOV is in radians. In microscopy, the field of view in high power (usually a 400-fold magnification when referenced in scientific papers) is called a high-power field , and is used as a reference point for various classification schemes. For an objective with magnification m {\displaystyle m} ,

2145-503: Is the much higher concentration of color-sensitive cone cells and color-sensitive parvocellular retinal ganglion cells in the fovea – the central region of the retina, together with a larger representation in the visual cortex – in comparison to the higher concentration of color-insensitive rod cells and motion-sensitive magnocellular retinal ganglion cells in the visual periphery, and smaller cortical representation. Since rod cells require considerably less light to be activated,

2210-401: Is the native resolution for DCI 4K digital projectors and displays. HDMI added support for 4096 × 2160 at 24   Hz in version 1.4 and 60   Hz in version 2.0. The resolution 5120 × 2160 is equivalent to 4K UHD ( 3840 × 2160 ) extended in width by one third, giving it a 64:27 aspect ratio (2. 370 or 21. 3 :9, commonly marketed as simply "21:9") and 11,059,200 total pixels. It

2275-443: Is the native resolution for DCI-compliant 2K digital projectors – active displays with this resolution are rare. The display aspect ratio is frequently wider than the native one, requiring non-square pixels. The resolution 2560 × 1080 is equivalent to Full HD ( 1920 × 1080 ) extended in width by one third, with an aspect ratio of 64:27 (2. 370 , or 21. 3 :9). Monitors at this resolution usually contain built-in firmware to divide

2340-450: Is visible by external apparatus, like when wearing spectacles or virtual reality goggles. Note that eye movements are allowed in the definition but do not change the field of view when understood this way. If the analogy of the eye's retina working as a sensor is drawn upon, the corresponding concept in human (and much of animal vision) is the visual field . It is defined as "the number of degrees of visual angle during stable fixation of

2405-525: The Jolla , Sony Xperia C , HTC Sensation , Motorola Droid RAZR , LG Optimus L9 , Microsoft Lumia 535 , and Samsung Galaxy S4 Mini have displays with the qHD resolution, as does the PlayStation Vita portable game system. The HD or 720p resolution of 1280 × 720 pixels stems from high-definition television (HDTV), where it originally used 50 or 60 frames per second. With its 16:9 aspect ratio, it

2470-602: The Nexus 6 smartphone. By the mid-2010s, it was a common resolution among flagship phones such as the HTC 10 , the Lumia 950 , and the Galaxy S6 and S7. Ultrawide (curved) monitors with a 32:9 aspect ratio and a 5120 × 1440 resolution have been referred to as Dual QHD or DQHD for short. It is sometimes also called "Super-Ultrawide" for marketing purposes. The resolution 3200 × 1800 has

2535-654: The UHD-1 broadcast standard from DVB . It is also the minimum resolution requirement for CEA's definition of an Ultra HD display. Before the publication of these standards, it was sometimes casually referred to as "QFHD" (Quad Full HD). The first commercial displays capable of this resolution include an 82-inch LCD TV revealed by Samsung in early 2008, the Sony SRM-L560, a 56-inch LCD reference monitor announced in October 2009, an 84-inch display demonstrated by LG in mid-2010, and

2600-706: The UK Schmidt Telescope had a field of view of 30 sq. degrees. The 1.8 m (71 in) Pan-STARRS telescope, with the most advanced digital camera to date has a field of view of 7 sq. degrees. In the near infra-red WFCAM on UKIRT has a field of view of 0.2 sq. degrees and the VISTA telescope has a field of view of 0.6 sq. degrees. Until recently digital cameras could only cover a small field of view compared to photographic plates , although they beat photographic plates in quantum efficiency , linearity and dynamic range, as well as being much easier to process. In photography,

2665-622: The 16:10 aspect ratio had virtually disappeared from the Windows laptop display market (although Mac laptops are still mostly 16:10, including the 2880 × 1800 15" Retina MacBook Pro and the 2560 × 1600 13" Retina MacBook Pro). One consequence of this transition was that the highest available resolutions moved generally downward (i.e., the move from 1920 × 1200 laptop displays to 1920 × 1080 displays). In response to usability flaws of now common 16:9 displays in office/professional applications, Microsoft and Huawei started to offer notebooks with

2730-436: The 16:10 aspect ratio longer than the entertainment industry, but in the 2005–2010 period, computers were increasingly marketed as dual-use products, with uses in the traditional computer applications, but also as means of viewing entertainment content. In this time frame, with the notable exception of Apple, almost all desktop, laptop, and display manufacturers gradually moved to promoting only 16:9 aspect ratio displays. By 2011,

2795-461: The 16:10 ratio. The 16:10 ratio allowed some compromise between showing older 4:3 aspect ratio broadcast TV shows, but also allowing better viewing of widescreen movies. However, around the year 2005, home entertainment displays (i.e., TV sets) gradually moved from 16:10 to the 16:9 aspect ratio, for further improvement of viewing widescreen movies. By about 2007, virtually all mass-market entertainment displays were 16:9. In 2011, 1920 × 1080 (Full HD,

2860-460: The display, design and battery life while criticizing the in-screen fingerprint sensor and the camera processing. Tom's Guide also gave it 4/5 stars, calling it "a budget phone with a big and colorful screen, solid performance and a sleek design" albeit with an "underwhelming battery life". CNET gave it an 8.4/10, describing it as "one of the best budget phones", and Digital Trends called it "the budget Samsung phone of your dreams". The A50

2925-430: The era of the cathode ray tube (CRT). The 16:10 aspect ratio had its largest use in the 1995–2010 period, and the 16:9 aspect ratio tends to reflect post-2010 mass-market computer monitor, laptop, and entertainment products displays. On CRTs, there was often a difference between the aspect ratio of the computer resolution and the aspect ratio of the display causing non-square pixels (e.g. 320 × 200 or 1280 × 1024 on

2990-424: The eyes". Note that eye movements are excluded in the visual field's definition. Humans have a slightly over 210-degree forward-facing horizontal arc of their visual field (i.e. without eye movements), (with eye movements included it is slightly larger, as you can try for yourself by wiggling a finger on the side), while some birds have a complete or nearly complete 360-degree visual field. The vertical range of

3055-465: The field of view is that part of the world that is visible through the camera at a particular position and orientation in space; objects outside the FOV when the picture is taken are not recorded in the photograph. It is most often expressed as the angular size of the view cone, as an angle of view . For a normal lens focused at infinity, the diagonal (or horizontal or vertical) field of view can be calculated as: where f {\displaystyle f}

3120-764: The field of view is usually expressed as an angular area viewed by the instrument, in square degrees , or for higher magnification instruments, in square arc-minutes . For reference the Wide Field Channel on the Advanced Camera for Surveys on the Hubble Space Telescope has a field of view of 10 sq. arc-minutes, and the High Resolution Channel of the same instrument has a field of view of 0.15 sq. arc-minutes. Ground-based survey telescopes have much wider fields of view. The photographic plates used by

3185-643: The first smartphone with a 4K display, and in 2017 Sony announced the Xperia XZ Premium, the first smartphone with a 4K HDR display. 4096 × 2160 , referred to as DCI 4K , Cinema 4K or 4K ×  2K , is the resolution used by the 4K container format defined by the Digital Cinema Initiatives Digital Cinema System Specification, a prominent standard in the cinema industry. This resolution has an aspect ratio of 256:135 (1.8 962 :1), and 8,847,360 total pixels. This

3250-408: The image resolution (one determining factor in accuracy). Working distance is the distance between the back of the lens and the target object. In tomography , the field of view is the area of each tomogram. In for example computed tomography , a volume of voxels can be created from such tomograms by merging multiple slices along the scan range. In remote sensing , the solid angle through which

3315-407: The linear field of view in millimeters per meter. Then, using the small-angle approximation : In machine vision the lens focal length and image sensor size sets up the fixed relationship between the field of view and the working distance. Field of view is the area of the inspection captured on the camera’s imager. The size of the field of view and the size of the camera’s imager directly affect

3380-612: The native resolution of Blu-ray ) was the favored resolution in the most heavily marketed entertainment market displays. The next standard, 3840 × 2160 (4K UHD), was first sold in 2013. Also in 2013, displays with 2560 × 1080 (aspect ratio 64:27 or 2. 370 , however commonly referred to as "21:9" for easy comparison with 16:9) appeared, which closely approximate the common CinemaScope movie standard aspect ratio of 2.35–2.40. In 2014, "21:9" screens with pixel dimensions of 3440 × 1440 (actual aspect ratio 43:18 or 2.3 8 ) became available as well. The computer display industry maintained

3445-503: The number of distinct pixels that can be displayed on a screen, which affects the sharpness and clarity of the image. It can be controlled by various factors, such as the type of display device, the signal format, the aspect ratio, and the refresh rate. Some graphics display resolutions are frequently referenced with a single number (e.g. in "1080p" or "4K"), which represents the number of horizontal or vertical pixels. More generally, any resolution can be expressed as two numbers separated by

3510-399: The physical dimensions of the graphics display can be used to calculate its pixel density . An increase in the pixel density often correlates with a decrease in the size of individual pixels on a display. Some graphics displays support multiple resolutions and aspect ratios, which can be changed by the user or by the software. In particular, some devices use a hardware/ native resolution that

3575-457: The result of this distribution is further that peripheral vision is much more sensitive at night relative to foveal vision (sensitivity is highest at around 20 deg eccentricity). Many optical instruments, particularly binoculars or spotting scopes, are advertised with their field of view specified in one of two ways: angular field of view, and linear field of view. Angular field of view is typically specified in degrees, while linear field of view

3640-418: The same field rate (a 12.5% increase, as one field of 1080i video is 1,036,800 pixels, and one frame of 720p video is 921,600 pixels). Although the number of pixels is the same for 1080p and 1080i, the effective resolution is somewhat lower for the interlaced format, as it is necessary to use some vertical low-pass filtering to reduce temporal artifacts such as interline twitter . Sometimes, this resolution

3705-404: The screen into two 1280 × 1080 screens. 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 . QHD (Quad HD) or 1440p

3770-445: The screen into two 1920 × 1080 screens, or one 2560 × 1080 and one 1280 × 1080 screen. The resolution 3840 × 1600 has a 12:5 aspect ratio, i.e. 2.4 or 21.6:9, which is commonly marketed as simply "21:9". It is equivalent to WQXGA ( 2560 × 1600 ) extended in width by 50%, or 4K UHD ( 3840 × 2160 ) reduced in height by 26%. This resolution is commonly encountered in cinematic 4K content that has been cropped vertically to

3835-474: The standard HDTV format, because it is exactly 4 times the width and 3 times the height of VGA, which has the same number of lines as NTSC signals at the SDTV 4:3 aspect ratio. Pragmatic technical constraints made them choose the now well-known 16:9 formats of 1280 × 720 and 1920 × 1080 instead, which were 2 times and 3 times the width of VGA respectively. In October 2006, Chi Mei Optoelectronics (CMO) announced

3900-523: The visual field in humans is around 150 degrees. The range of visual abilities is not uniform across the visual field, and by implication the FoV, and varies between species . For example, binocular vision , which is the basis for stereopsis and is important for depth perception , covers 114 degrees (horizontally) of the visual field in humans; the remaining peripheral ~50 degrees on each side have no binocular vision (because only one eye can see those parts of

3965-418: The visual field). Some birds have a scant 10 to 20 degrees of binocular vision. Similarly, color vision and the ability to perceive shape and motion vary across the visual field; in humans color vision and form perception are concentrated in the center of the visual field, while motion perception is only slightly reduced in the periphery and thus has a relative advantage there. The physiological basis for that

4030-459: Was Samsung's best-selling smartphone in 2019, the best-selling smartphone in Europe in 2019, and the third best-selling phone in the world for the third quarter of 2019. FHD%2B A display resolution standard is a commonly used width and height dimension (display resolution) of an electronic visual display device, measured in pixels . This information is used for electronic devices such as

4095-588: Was added in DisplayPort 1.2, no DisplayPort timing controllers (TCONs) existed which were capable of processing the necessary amount of data from a single video stream. As a result, the first 4K monitors from 2013 and early 2014, such as the Sharp PN-K321, Asus PQ321Q, and Dell UP2414Q and UP3214Q, were addressed internally as two 1920 × 2160 monitors side by side instead of a single display and made use of DisplayPort's Multi-Stream Transport (MST) feature to multiplex

4160-607: Was released in December 2020. An update to Android 11 with One UI 3.1 was released in March 2021, the final OS update for the Galaxy A50. The last security update for the Galaxy A50 was provided in February 2023. Samsung stated that the phone will not be getting Android 12 One UI 4 and any further OS Updates. The A50 received mostly positive reviews. PCWorld gave it 4/5 stars, praising

4225-523: Was the 34-inch LG 34UM95-P. This monitor was first released in Germany in late December 2013, before being officially announced at CES 2014. The resolution 3840 × 1080 is equivalent to two Full HD ( 1920 × 1080 ) displays side by side or one vertical half of a 4K UHD ( 3840 × 2160 ) display. It has an aspect ratio of 32:9 (3. 5 :1), close to the 3.6:1 ratio of IMAX UltraWideScreen 3.6 . Samsung monitors at this resolution contain built-in firmware to divide
