Sida tignoolajiyada cusub, HDMI waxay bixisaa hagaajin ku saabsan fiilada VGA ee hore dhinac kasta. ^(VGA)HDMI waxay u taagan tahay heer sare, ha ahaato heerka gudbinta, heerka bandhigga, xallinta muuqaalka, ama xitaa dabeecadda calaamada la isticmaalo.

Taas marka la yiraahdo, VGA way ka fog tahay dabar-goynta. Iyadoo interface-kii hore uu si tartiib tartiib ah meesha uga baxayo, aalado badan ayaa wali isticmaala dekedaha VGA , taas oo ka dhigaysa muhiim in la fahmo awoodeeda iyo xaddidaaddeeda. Markaa halkan waxaa ku yaal aasaas u ah kala duwanaanshaha iyo astaamaha is- dhexgalka VGA iyo HDMI .

Hordhac VGA iyo HDMI

VGA ( Video Graphics Array ) waa muuqaal muuqaal ah oo ay IBM ugu talagashay kormeerayaasha kumbuyuutarka ee 1987. Dekedda 15-pin ee 3- saf ee VGA waxay noqotay muuqaal meel walba leh oo ka mid ah Motherboard-yada PC, consoles-yada ciyaaraha, iyo ciyaartoyda DVD-ga^(DVD) .

Sida magacu soo jeediyo, interface-ka VGA -ga waxa uu sido oo kaliya macluumaadka muuqaalka, taasna sidoo kale marka la eego qaraar loo arko mid hooseeya marka loo eego heerarka maanta. Hase yeeshee ku habboonaanteeda sahlan iyo taageerada soo saaraha baahsan waxay ka dhigan tahay is-dhexgalka ayaa sii waday in la horumariyo ilaa 2010 markii warshaduhu ay ugu dambeyntii u beddeleen heerka HDMI .

HDMI ( Interface Multimedia Interface Qeexida Sare^{(High Definition Multimedia Interface)} ) ayaa la soo bandhigay 2002 si ay u qaado xogta maqalka iyo muuqaalka labadaba iyada oo leh hal fiilo, taas oo sidoo kale lagu hagaajinayo xallinta iyo qaabeynta. Dhowrka sano ee soo socda, waxay si dhakhso ah u noqotay halbeegga dhabta ah ee isku xidhka warbaahinta badan.

HDTV^(HDTVs) -yada dhowaan la furayo ayaa si degdeg ah u dhexgeliyey tignoolajiyadan, iyada oo la isticmaalayo isku xidhayaasha HDMI^(HDMI) sidii isku xidh maqal iyo muuqaal midaysan. Iyo sida HDMI ay gadaal u raacday DVI ( Digital Visual Interface ), inta badan aaladaha casriga ah ayaa isticmaali kara.

Tani waxay ka dhigeysaa isticmaalayaasha VGA meel cidlo ah, si kastaba ha noqotee, maadaama aad u baahan tahay adabtarada khaaska ah si aad VGA ugu bedesho calaamadaha HDMI , xitaa markaa waxqabadka wuxuu noqon karaa mid dhib badan. Tani waa sababta xitaa consoles-yada ciyaaraha iyo aaladaha qulqulka ay sidoo kale u haajireen tignoolajiyada cusub, iyaga oo ku biiray kombuyuutarrada si ay u daadiyaan dekedda VGA .

Farqiga Aasaasiga ah: Analog vs Digital

Farqiga ugu cad ee u dhexeeya labada is-dhexgal waa nooca calaamada la isticmaalo. Xidhiidhada VGA^(VGA) waxay wataan calaamado muuqaal ah oo analooga ah, halka HDMI loogu talagalay gudbinta dhijitaalka ah.

Laakiin maxay taasi ka dhigan tahay? Asal ahaan^(Basically) , calaamadaha analoogga waxa ay ka kooban yihiin xog is daba joog ah, halka calaamadaha dhijitaalka ahi ay ka samaysan yihiin qiimeyo kala duwan.

Tani waxay ka dhigaysaa gudbinta analoogga mid sahlan in la gudbiyo, inkastoo aan si gaar ah waxtar lahayn. Gudbinta dhijitaalka^(Digital) ah, dhanka kale, waxay badin kartaa macluumaad badan oo u nugul faragelinta.

HDMI: Gudbinta Multimedia Full

Interface analooga ahaan, VGA waxa ay awood u leedahay in ay gudbiso hal nooc oo macluumaad ah markiiba. Tani waxay xaddidaysaa gudbinta fiidiyowga oo keliya, taas oo sidoo kale ah heer hoose oo tayada sawirka ah.

HDMI , dhanka kale, waxay gudbin kartaa nooc kasta oo xogta dhijitaalka ah. Interface-ka ayaa loo sameeyay si uu u daboolo calaamadaha muuqaalka iyo maqalka labadaba, iyada oo aan waxyeello loo geysan daacadnimada midkood.

Isla fiilada HDMI waxay gudbin kartaa kanaalka 32 ee codka sare ee Dolby Digital iyo sidoo kale 1080p fiidiyoow fiidiyoow ah oo isku mar ah. Tani waxay ka dhigtay HDMI interface-ka ugu muhiimsan ee codsiyada waxqabadka sare leh sida 4K game consoles iyo Blu-Ray ciyaartoyda.

VGA: Ka fudud oo ka dhaqso badan

Thanks to dabeecadda adag ee socodka xogta HDMI , macluumaadka waxay u baahan tahay in lagu kala saaro calaamado la isticmaali karo ka hor dib u ciyaarida. Tani waxay soo bandhigaysaa dib-u-dhac yar oo leh xidhiidh kasta oo HDMI ah, iyada oo aan loo eegin sida awoodda nidaamka su'aasha.

Dhibaatadani kuma jirto VGA . Calaamadaheeda analoogga ah ayaa si degdeg ah loogu tarjumi karaa sawirada dhaqaaqa ee shaashadda, iyada oo aan nooc ka mid ah habayn ka dib ama beddelaad. Daahitaankan hoose waa nimcada kaliya ee VGA ee badbaadinaysa, maadaama ay ku lumiso HDMI mitir kasta oo kale.

Nasiib darrose, waa tayada dhif iyo naadir ku soo gasho codsiyada badankooda. Daahitaanka wax gelinta ayaa kaliya soo bandhigaya dib u dhac yar oo ku yimid dib u ciyaarista dhabta ah, iyada oo aan wax saameyn ah ku yeelan tayada dib u ciyaarista haba yaraatee. Ilaa waxa ku jira uu yahay mid xasaasi u ah wakhtiga, ma jirto faa'iido la aqoonsan karo oo ku jirta isticmaalka VGA .

HDMI: Dabacsan oo deggan

Qof kasta oo la soo shaqeeyay kormeerayaashii hore ee CRT wuxuu ogyahay inaadan ku xidhi karin VGA qalab socda oo aad filayso inuu shaqaynayo. Waxaad ku samayn kartaa HDMI , in kastoo.

Lagu magacaabo hot-pluging, shaqadani waxay u oggolaanaysaa bandhigyada HDMI in lagu shido duullimaadyada, iyada oo aan dib loo bilaabin dhammaan nidaamka soo saara quudinta fiidiyowga. ^(HDMI)Codsiyo badan oo ganacsi, awooddani waa badbaado.

Xadhkaha HDMI^(HDMI) sidoo kale aad bay ugu nugul yihiin faragelinta korantada, sababtoo ah gaashaankooda qaro weyn iyo calaamadaha dhijitaalka ah. Tani waxay ka dhigeysaa inay ka door fiican yihiin VGA ee la geynayo hareeraha ilaha shucaaca.

HDMI: Pixels badan oo degdeg u soo kicinaya^{(Refresh Faster)}

Ma aha oo kaliya HDMI inay taageerto xallinta sare (ilaa 4K) marka loo eego VGA laakiin waxay sidoo kale taageertaa heerar cusub oo aad u sarreeya, oo kor u kacaya 240 Hz. Faa'iidadani hadda maaha aragti kaliya, oo leh kormeerayaal heersare ah iyo TV-yada UHD^{(UHD TVs)} si joogto ah u bixiya faahfaahintan horumarsan.

Nooca ugu dambeeyay ee heerka, HDMI 2.1a , waxay taageertaa xitaa 8K, oo ay weheliso heerarka sare ee fiidiyowga sida Dolby Vision and HDR10+ .

Taas bedelkeeda, nooca ugu dambeeya ee VGA wuxuu awood u leeyahay oo keliya xallinta ugu badan ee 1600 × 1200, kaas oo sidoo kale ah heerka dib-u-cusboonaysiinta ee 60 Hz kaliya. Marka laga reebo isku-dhafka maqalka, tani waa sabab kale oo weyn oo TV-ga iyo soo-saareyaasha soo-saareyaasha kumbuyuutarka ay si buuxda ugu wareegayaan HDMI .

VGA vs HDMI: Si kooban

HDMI waxay si cad u tahay interface ugu fiican ee gudbinta qulqulka badan ee warbaahinta. Waxay meesha ka saartaa baahida fiilooyinka maqalka ah waxayna bixisaa xalal la wanaajiyey iyo qaab-dhismeedyo. DisplayPort waa interface kale ee kaliya ee bixiya astaamo la mid ah.

Taasi waa la filayaa, si kastaba ha ahaatee, iyadoo la tixgelinayo in VGA ay tahay tignoolajiyada aad uga da' weyn. Waqtigeedii, VGA waxay ahayd tignoolajiyad la yaab leh oo adag, oo ku gudbisa durdurrada fiidyaha iyada oo loo marayo calaamado analoog ah oo fudud iyada oo aan wax la gelin ah.

Laakin sida heerarkii hore ee is dhexgal tignoolajiyadeed kasta, maalmihii VGA ayaa soo dhowaanaya. Da'dan sawirada 4K iyo kormeerayaasha 120 Hz, HDMI waa qayb muhiim ah oo ka mid ah nidaamka deegaanka madadaalada. VGA waxay faa'iido u leedahay oo kaliya in lagu dhex geliyo qalabkii hore sida projectors-ka^{(interface with older devices like projectors)} .

VGA vs. HDMI: How Are They Different?

As the newer technology, HDMI offers improvements upon the older VGA cable in еvery respect. HDMI ѕtands superior, be it thе rate of transmission, displaу rate, video resolution, or even the nature of the signal used.

That being said, VGA is far from extinct. While the older interface is gradually being phased out, many devices still use VGA ports, making it important to understand its strengths and limitations. So here is a primer on the differences and features of the VGA and HDMI interfaces.

Introduction to VGA and HDMI

VGA (Video Graphics Array) is a display interface designed by IBM for computer monitors back in 1987. The 15-pin 3-row VGA port became a ubiquitous feature in PC motherboards, gaming consoles, and DVD players.

As the name suggests, the VGA interface only carries visual information, and that too at a resolution considered low by today’s standards. Yet its easy compatibility and widespread manufacturer support meant the interface continued to be developed until 2010 when the industry finally made the switch to the HDMI standard.

HDMI (High Definition Multimedia Interface) was introduced in 2002 to carry both audio and visual data with a single cable, that too at a much-improved resolution and framerate. Over the next several years, it quickly became the de facto standard for multimedia connectivity.

The soon-to-be-launched HDTVs swiftly integrated this technology, using HDMI connectors as a unified audio-visual interface. And as HDMI was backward compatible with DVI (Digital Visual Interface), most modern devices could make use of it.

This leaves VGA users in the lurch, however, as you need a specialized adapter to convert VGA to HDMI signals, and even then performance can be spotty. This is why even gaming consoles and streaming devices have also migrated to the newer technology, joining computers in ditching the VGA port.

The Fundamental Difference: Analog vs Digital

The most obvious difference between the two interfaces is the type of signal used. VGA connections carry analog video signals, while HDMI is meant for digital transmission.

But what does that mean? Basically, analog signals contain a continuous gradient of information, while digital signals are made up of discrete values.

This makes analog transmissions easier to transmit, though not particularly efficient. Digital transmissions, on the other hand, can pack a lot of information and are less susceptible to interference.

HDMI: Full Multimedia Transmission

As an analog interface, VGA is only capable of transmitting one type of information at a time. This limits it to video transmission alone, that too at a lower level of image quality.

HDMI, on the other hand, can transmit any type of digital data. The interface has been developed to accommodate both video and audio signals, without compromising on the fidelity of either.

The same HDMI cable can transmit 32 channels of high-resolution Dolby Digital audio as well as a 1080p resolution video stream simultaneously. This has made HDMI the mainstay interface for high-performance applications like 4K gaming consoles and Blu-Ray players.

VGA: Simpler and Faster

Thanks to the complex nature of an HDMI data stream, the information needs to be decoded into usable signals before playback. This introduces a small input lag with any HDMI connection, no matter how powerful the system in question.

This problem is not present in VGA. Its analog signals can be rapidly translated into moving images on the screen, without any sort of post-processing or conversion. This low input lag is VGA’s only saving grace, as it loses to HDMI on every other metric.

Sadly, it is a quality that rarely comes into play in most applications. An input lag just introduces a slight delay in the actual playback, without affecting the playback quality in the slightest. Unless the content is extremely time sensitive, there is no discernible advantage in using VGA.

HDMI: Flexible and Stable

Anyone who has worked with old CRT monitors knows that you cannot just plug a VGA connector into a running device and expect it to work. You can do it in HDMI, though.

Called hot-plugging, this functionality allows HDMI displays to be switched on the fly, without having to restart the whole system generating the video feed. For many commercial applications, this ability is a lifesaver.

HDMI cables are also less prone to electromagnetic interference, because of their thick shielding and digital signals. This makes them a better choice than VGA for deploying around radiation sources.

HDMI: More Pixels That Refresh Faster

Not only can HDMI support higher resolutions (up to 4K) than VGA but it also supports much higher refresh rates, going up to 240 Hz. This advantage is no longer just theoretical, with high-end monitors and UHD TVs regularly offering these advanced specs.

The latest version of the standard, HDMI 2.1a, supports even 8K, along with advanced video standards like Dolby Vision and HDR10+.

In contrast, the latest version of VGA is only capable of a maximum resolution of 1600×1200, that too at the standard refresh rate of 60 Hz only. Apart from audio integration, this is another big reason why TV and computer display manufacturers are completely shifting to HDMI.

VGA vs HDMI: In a Nutshell

HDMI is clearly the better interface for transmitting any multimedia stream. It eliminates the need for an audio cable and offers improved resolutions and framerates. DisplayPort is the only other interface to offer similar features.

That is to be expected, however, considering that VGA is a much older technology. For its time, VGA was a surprisingly robust technology, transmitting video streams through simpler analog signals without any input lag.

But like older standards of any technological interface, the days of VGA are drawing to a close. In this age of 4K graphics and 120 Hz monitors, HDMI is an essential component of the entertainment ecosystem. VGA is only useful to interface with older devices like projectors.
