Inta badan waa inaad doorataa inta u dhaxaysa xallinta sida 720p, 1080p, ama 1440p (iyo in ka badan) xaalado kala duwan. Waa maxay macnaha ikhtiyaarradan, goormaadse dooranaysaa ikhtiyaarkee?

Waa maxay Qaraar?

Marka hore, aynu si degdeg ah u fahanno waxa “xalku” yahay. Sawirada dhijitaalka ah waxa loo kala qaybiyaa "picture element" ama "pixels." ^(Digital)Pixel kastaa wuxuu leeyahay midab gaar ah iyo qiimo dhalaal, iyo pixels badan ayaa lagu habeeyey shabaqyo si ay sawirro u sameeyaan.

Inta badan pixels waxaa ku jira sawirka, si faahfaahsan ayuu sawirkaasi noqon doonaa. Sawirka "xalin hoose" ayaa u muuqda mid hadhuudh ah, wayna fududahay in la arko pixels-yada dhabta ah haddii aad si dhow u eegto. Sawirka "xarar sare" wuxuu u muuqdaa mid siman oo fiiqan halkaasoo pixels-ka gaarka ah aysan ka muuqan indhaha qaawan iyada oo aan la weynayn. 

Xallinta waa sifada warbaahinta dhijitaalka ah (tusaale, sawir, muuqaal, ama ciyaarta muqaal) iyo aaladaha bandhiga sida LCD TV. 

Qaraarka Dhaladka^{(Native Resolution)} ee Shaashadaada^{(Your Screen)}

Bandhigyada fidsan ee casriga ah waxay leeyihiin LCD ama OLED^{(LCD or OLED)} pixels jireed ( Dareere Crystal Displays^{(Liquid Crystal Displays)} iyo Organic Light-emitting Diodes ), kaas oo ah xallinta "hooyo" ee bandhigga. Haddii sawirka shaashadda uu ku habboon yahay xallinta asalka ah, markaa pixel kasta oo shaashadda ku yaal wuxuu leeyahay qiime u dhigma oo u dhigma, taas oo ka dhigan xaalad ku habboon.

Iswaafajin la'aanta udhaxeysa xallinta bandhigga iyo waxa ku jira ayaa laga yaabaa inay horseeddo hab loo yaqaan "qashin," kaas oo dhaawacaya tayada sawirka.

Xallinta nuxurka

Sida kor ku xusan, nuxurku wuxuu leeyahay xallintiisa. Tusaale ahaan, filimada BluRay caadiga ah waxay leeyihiin xallinta 1080p (1920×1080). 

"p" waxay u taagan tahay "horumar", taas oo macnaheedu yahay in sawirku dib u cusbooneysiiyo wareeg kasta oo ka mid ah heerka soo kicinta kormeeraha. Heerka soo kicinta waa heerka uu kormeeruhu dib u sawiro sawirka aad aragto. 

Taas bedelkeeda waa 1080i, hab duug ah oo loo maro taranka sawirka halka "i" u taagan tahay "isku-dhafan. "Isku^{(” Interlaced)} -dhex-gal waxay ka dhigan tahay in shaashad kasta oo dib u soo celisa ay dib u sawirto xariiqyada aan fiicneyn iyo xitaa-tirada pixels. 

Xallinta sida 720p ama 1080p kaliya waxay sheegaysaa dhererka sawirka ee maaha dhererkiisa. Shaashad 1920 × 1080 ah iyo 2560 × 1080 shaashad labaduba waa 1080p, laakiin mid ayaa leh wadarta guud ee pixels iyo “saamiga dhinac” ballaaran. Saamiga dhinaciisu waa saamiga u dhexeeya xadadka pixel-ka toosan iyo kuwa taagan. Shaashadda 1920×1080 waa 16 pixels oo balac ah sagaalkii pixels kasta oo dherer ah waxaana loo yaqaannaa 16:9 shaashad.

Fiidiyowga^(Video) iyo waxa ku jira sawirku waxay leeyihiin xalal go'an, taas oo macnaheedu yahay in 720p fiidiyoow ah oo ku ciyaaraya shaashad 1080p uusan lahayn wax faahfaahin ah oo ka badan 1080p fiidiyoow ah oo ku ciyaaraya shaashadda 720p.

Qiyaasta xallinta

Hadda, aynu qeexno "qashin. Bal qiyaas^{(” Imagine)} inaad ku ciyaareyso filim 1080p muuqaal 2160p (4K). Shaashadda 4K waxay leedahay afar jeer tirada guud ee pixels si aad ugu habboonaato afar sawir oo 1080p ah gudaha 2160p asal ahaan. Taasi waxay la macno tahay inaad u baahan tahay inaad ku qarxiso sawirka 1080p afar qodob si aad u buuxiso shaashadda 2160p.

Ficil ahaan, tani waxay si fiican u shaqeysaa tan iyo markii ay ka kooban tahay 1080p ay si siman u qaybsanto 2160p. Marka sida saxda ah u qaybsanaan kari waayo, hababka cabbiraadda ee lagu qiyaaso qiimayaasha pixels waa in la isticmaalaa, taas oo sii hoos u dhigaysa sawirka u dambeeya.

Iyadoo hababka ismiidaaminta casriga ahi ay aad ugu fiican yihiin ilaalinta tayada sawirka, marka aad dooranayso xallinta waxa ku jira, ujeeddadu waxay tahay mid ka mid ah waxyaabaha asalka u ah ama waxa ku jira kuwaas oo si siman u qaybiya xallinta shaashadda si loo helo natiijooyinka ugu fiican.

Xallinta Dhaqdhaqaaqa^{(Dynamic Resolution)} leh iyo Dib-u-dhiska Sawirka^{(Image Reconstruction)} ee Ciyaaraha Fiidyaha^{(Video Games)}

Si ka duwan sawirada iyo fiidyaha, ciyaaraha fiidyaha iyo software-yada kale ee bixiya garaafyada waqtiga-dhabta ah waxay ku samayn karaan go'aamo aan sabab lahayn. Tusaale ahaan, haddii aad tahay gamer PC, waxaad dooran kartaa inaad ciyaar ku bixiso qaraarada sida 720p, 1080p, ama 1440p. Xataa ciyaaraha konsole waxa ay siiyan ciyaartoyda go'aan xadidan marka ay timaado wax soo saarka xalinta.

Si kastaba ha ahaatee, ciyaaraha casriga ahi waxay si firfircoon u beddelaan xalalkooda. Tusaale ahaan, ciyaarta waxaa laga yaabaa inay bartilmaameedsato 1440p ama 2160p laakiin waxay ku soo bandhigtaa xirmo gaar ah xal hoose si loo ilaaliyo waxqabadka ciyaarta. Software-ka ciyaarta fiidyaha laftiisa ayaa markaa miisaamaya qaabka xallinta hoose ee xallinta saxda ah. 

Ciyaaryahanka, tani inta badan waa mid aan la fahmi karin ama waxay u muuqataa dawakhaad kooban sawirka laakiin si weyn uma saameynayso tayada sawirka kulaylka ficilka.

720p vs 1080p vs 1440p: Kiisaska u isticmaal mid walba

Iyadoo la tixgelinayo dhammaan macluumaadkan, xallintee ayaa ugu fiican isticmaalkee?

720p Qaraarka^{(720p Resolution)}

Xallinta 720p ayaa weli meel ku leh waqtiyada casriga ah, laakiin meeshaas kuma jirto TV weyn ama kormeeraha kumbuyuutarka. Dooro 720p kaliya marka aad ku arkayso waxa ku jira taleefanka gacanta. Waa inaad u doorataa xallin sare wax walba (ay ku jiraan tablets), adigoo u malaynaya in xajmigu aanu xadidnayn.

720p waa ku haboon yahay marka lagu ciyaarayo ciyaaraha fiidiyooga ee qalabka tamarta yar (sida sawirada isku dhafan), laakiin hubi inaadan haysan ikhtiyaarka xallinta firfircoon ama hababka dib u dhiska sawirka si aad u nadiifiso sawirka.

1080p Qaraarka^{(1080p Resolution)}

1080p waa xalka ugu caansan maanta. Inta badan telefoonada waxay bixiyaan 1080p ama xallin ka fiican; waa shaashadda kumbuyuutarka ee ugu caansan iyo xallinta telefishanka. 1080p waxay bixisaa dheelitirnaan heersare ah oo u dhexeeya tayada sawirka, cabbirka faylka, shuruudaha bandwidth, iyo waxqabadka.

1080p waa bartilmaameed yar oo lagu gaaro inta badan PC-yada ciyaaraha casriga ah waxaana hadda loo arkaa bartilmaameedka xallinta ciyaaraha guud.

1440p Qaraarka^{(1440p Resolution)}

1440p wuxuu bixiyaa meel dhexe oo u dhaxaysa tayada sawirka 1080p iyo 2160p 4K oo buuxa. 1440p ee xallinta fiidyowga ayaa waxtar leh haddii taasi tahay muujinta xallinta asalka ah. Ciyaartoyda, 1440p waxay siisaa isku dhafka ugu fiican ee tayada sawirka iyo waxqabadka. Waa mid ka mid ah sababaha ugu waaweyn ee heerka cusboonaysiinta sare ee 1440p kormeerayaasha ay caan ku yihiin PC iyo gamers console^{(console gamers)} .

720p vs. 1080p vs. 1440p: Which Resolution Is Better and Does It Matter?

You’ll often have to choose between resolutions such as 720p, 1080p, or 1440p (and more) in various contexts. What do thesе орtions mean, and when should you pick which optіon?

What Is Resolution?

First, let’s get a quick understanding of what “resolution” is. Digital images are broken up into “picture elements” or “pixels.” Each pixel has a specific color and brightness value, and multiple pixels are arranged in a grid to form pictures.

The more pixels there are in an image, the more detailed that image will be. A “low-resolution” image appears grainy, and it’s easy to see the actual pixels if you look closely. A “high-resolution” image looks smooth and sharp where individual pixels are not visible to the naked eye without magnification. 

Resolution is an attribute of digital media (e.g., a photo, video, or video game) and a display device such as an LCD TV. 

The Native Resolution of Your Screen

Modern flat panel displays have LCD or OLED physical pixels (Liquid Crystal Displays and Organic Light-emitting Diodes), which is the display’s “native” resolution. If the on-screen image matches the native resolution exactly, then every pixel on the screen has a corresponding unique value, which constitutes an ideal situation.

A mismatch between the display’s resolution and the content may lead to a process known as “scaling,” which hurts picture quality.

The Resolution of Content

As mentioned above, content has its resolution. For example, standard BluRay films have a resolution of 1080p (1920×1080). 

The “p” stands for “progressive”, which means that the image refreshes with every cycle of the monitor’s refresh rate. The refresh rate is the rate at which the monitor redraws the picture you see. 

In contrast is 1080i, an obsolete approach to image reproduction where the “i” stands for “interlaced.” Interlaced means that every screen refresh redraws the odd and even-numbered lines of pixels. 

A resolution like 720p or 1080p only mentions the height of the image and not its length. A 1920×1080 screen and a 2560×1080 screen are both 1080p, but one has a higher total number of pixels and a wider “aspect ratio.” The aspect ratio is the ratio between horizontal and vertical pixel lines. A 1920×1080 screen is 16 pixels wide for every nine pixels tall and is called a 16:9 screen.

Video and photographic content have fixed resolutions, which means that a 720p video playing on a 1080p screen doesn’t have any more detail than a 1080p video playing on a 720p screen.

Resolution Scaling

Now, let’s define “scaling.” Imagine playing a 1080p film on a 2160p (4K) display. A 4K screen has four times the number of total pixels so that you could fit four 1080p image frames into a 2160p frame natively. That means you need to blow up a 1080p image by a factor of four to fill a 2160p screen.

In practice, this works well since 1080p content divides evenly into 2160p. When such perfect division isn’t possible, scaling methods that estimate the values of pixels have to be used, which further degrades the final image.

While modern scaling methods are much better at maintaining image quality, when choosing the resolution of your content, aim for either native content or content that evenly divides into the screen resolution for the best scaling results.

Dynamic Resolution and Image Reconstruction in Video Games

Unlike photos and videos, video games and other software that render real-time graphics can do so at arbitrary resolutions. For example, if you’re a PC gamer, you can choose to render a game at resolutions such as 720p, 1080p, or 1440p. Even console games offer players a limited set of choices when it comes to resolution output.

However, modern games dynamically change their resolution. For example, the game might target 1440p or 2160p but render individual frames at a lower resolution to preserve game performance. The video game software itself then scales the lower resolution frame to the correct output resolution. 

To the player, this is usually either imperceptible or appears as a brief fuzziness in the image but doesn’t significantly impact image quality in the heat of the action.

720p vs 1080p vs 1440p: Use Cases for Each

Taking all of this information into account, which resolution is the best for what use?

720p Resolution

The 720p resolution still has a place in modern times, but that place isn’t on a large TV or computer monitor. Choose 720p only when viewing content on a mobile phone. You should pick a higher resolution for everything (including tablets), assuming that bandwidth isn’t limited.

720p is suitable when playing a video game on low-powered hardware (such as integrated graphics), but make sure you don’t have a dynamic resolution option or any image reconstruction methods to clean the image up.

1080p Resolution

1080p is the most common resolution today. Most phones offer a 1080p or better screen resolution; it’s the most common computer screen and television resolution. 1080p provides an outstanding balance between image quality, file size, bandwidth requirements, and performance.

1080p is a trivial target to reach for most modern gaming PCs and is now considered the mainstream gaming resolution target.

1440p Resolution

1440p offers a middle ground between 1080p image quality and full-on 2160p 4K. 1440p for video resolution is helpful if that’s the display’s native resolution. For gamers, 1440p offers the best mix of image quality and performance. It’s one of the main reasons high refresh rate 1440p monitors are popular among PC and console gamers.
