Umxhasi weVidiyo yeSizukulwana esilandelayo kwiikhompyuthile zobuqu
Kule minyaka, imboni yekhompyutheni ibone inani elikhulu leenethiwekhi ezihlukeneyo zevidiyo. Umgangatho we-VGA uncede ukuzisa izixazululo eziphezulu kunye nombala ngaphandle kweevidiyo zokuqala zevidiyo. I-DVI yasifaka kwiibonakaliso zedijithali ezivumelekile ukuba zibe nombala omkhulu kunye nokucaca. Ekugqibeleni, i- HDMI idibanisa idijithali yevidiyo kunye nesignali yomsindo kwikhebula enye yokusetyenziswa kunye nekhamera yasekhaya kunye ne-PC. Ngoko ke, ngazo zonke ezi phuhliso, kutheni kukho umnxibelelwano we-DisplayPort? Yiloo nto inqaku eli lijonga ngayo ukuchaza.
Ukulinganiselwa kweeNxibelelanisi zeVidiyo ezikhoyo
Ngayinye yezona zixhobo ezintathu eziphambili zevidiyo zixakeke iingxaki ezicutha ukusetyenziswa kwazo kunye neziboniso zekhompyutha. Nangona bajongene neminye imiba, abanye bahlala. Makhe sijonge nganye kwiifom kunye neengxaki abanalo:
DVI
- I-DVI engabonanga iphela kwi-1920x1200 isombululo ngombala we-24-bit
- I-Dual-link DVI igxile kwi-2560x1600 isombululo ngombala we-24-bit
- Ukukhwelisa okukhulu kudinga ukuba umnxibelelwano uphawulwe kwikhadi / kubonakaliso
- Akukho inkxaso yomsindo
HDMI
- I-2.0 ye-2.0 ixhasa izigqibo ezi-4K kodwa ngokungaqhelekanga
- I-1.3 ixhasa isisombululo esiya kwi-2560x1600 ngesisombululo somsindo
- I-Version 1.1 isekela ukususela kwisisombululo se-1920x1200 ngokusasazwa komsindo
- Udidi lwe-1 lugqibelele kumitha engama-5 ngobude
DisplayPort Basics
I-DisplayPort yaphuhliswa phakathi kwamalungu e-Video Electronics Standards Association. Leli qela lamaqela angama-170 aqhuba kwaye anqume imilinganiselo ekufuneka isetyenziswe ngokubonisa iikhomputha. Eli akusiyo iqela elaphuhlisa imigangatho ye-HDMI. Ngenxa yeemfuno ezinkulu zeekhomputha kunye ne-IT industry, iqela le-VESA lenze i-DisplayPort.
Ngokubhekiselele ekukhoneni, iifowuni ze-DisplayPort kunye nezixhumi zibukeka zifana nezixhobo ze-USB okanye ze-HDMI ezisetyenziswa namhlanje kwiikhomputha ezininzi. Iimbononci ezincinci zenza i-cabling elula yenkqubo kwaye vumela ukuba isixhobo sibekwe kwiindawo ezininzi. Uninzi lweekhomputha zeekhompyutheni ezingenakukwazi ukulungelelanisa ngokufanelekileyo i-VGA okanye i-DVI isixhobo ngoku, kodwa iProfayili ye-DisplayPort yenzeke ukuba ibeke phezu kwayo. Ngokufanayo, icebo elincinci livumela ukuba izibane ezidibeneyo zibekwe kwibakethi enye ye-PCI kwi-desktop PC.
Izindlela zokusayina zamanje ezisetyenziselwa kwizixhumi ze-DisplayPort zivumela kwakhona inani elikhulu lomda womda wedatha phezu kwekhebula. Oku kuvumela ukuba kwandiswe ngaphaya kwe-2560x1600 imida yokusombulula i-DAL kunye ne-HDMI v1.3. Oku akuyona inkxalabo kwimiboniso ekhoyo, kodwa kubalulekile ukukhula kwangomso kwee-4K okanye i-UltraHD Displays ezifuna ezine i-bandwidth yedatha yevidiyo eqhelekileyo ye-1080p kwaye ekugqibeleni uye kwividiyo ye-8K. Ukongeza kule ntshukumo yevidiyo, i-cabling nayo inokuxhasa isambulelo somsindo esingaxinzekanga esine-8 esifana neso sixhobo se-HDMI.
Enye yeentuthuko eziphambili kunye ne-DisplayPort inkqubo nangona isitishi esincedisayo. Le iseshoni eyongezelelweyo kwimigangatho yevidiyo eqhelekileyo kwikhebula elingakwazi ukuqhuba ulwazi olongezelelweyo lwevidiyo okanye idatha malunga nezicelo ezifunayo. Umzekelo wale nto unokuxhamla kwi-webcam okanye kwi-port yase-USB eyenziwe kwikhompyutheni yekhomputha ngaphandle kwesidingo sokwakheka kwekhamera eyongeziweyo. Ezinye iinguqu ze-HDMI zongeze i-Ethernet kubo kodwa oku kuphunyezwa kakhulu.
Enye into efunekayo abantu abaninzi ukuba baqaphele kukuba abaxhunywa be - ThunderBolt basisiseko somgangatho we-DisplayPort kunye nezixhobo zecala ezisezantsi. Oku akunjalo kuzo zonke iinguqulelo nangona i-ThunderBolt 3 isekelwe kwi-USB 3.1 ii-connectors kunye nemigangatho eyenza izinto zidideke ngakumbi. Ngoko, ukuba i-PC yakho ineT ThunderBolt niqiniseke ukuba uhlolisise inguqulo ukuqinisekisa ukuba iyahambelana nesiboniso sakho.
Bonisa iPort ngaphezu kweChabling
Olunye ulungelelwano olubalulekileyo kunye nomgangatho we-DisplayPort kukuba uhamba ngaphaya komxhasi kunye nekhebula phakathi kwe-PC kunye nokubonisa. Iteknoloji ingasetyenziselwa ngaphakathi kubonakaliso bokubonakala kweso siqendu okanye incwadana yokunciphisa inani labaxhuma kunye ne-wiring efunekayo. Oku kungenxa yemigangatho ye-DisplayPort equka indlela yokubonisana ngqo.
Oko kuthetha ukuthini ukuba umboniso unokususa ezininzi iicomputer eziyimfuneko ukuguqula isignali yevidiyo kwikhadi levidiyo ibe enye inokusetyenziswa ukuqhuba ipaneli yeLCD ebonakalayo. Kunoko, iphaneli ye-LCD isebenzisa i-drivePort drive eyenza i-electronics ihambe. Okubalulekileyo, uphawu oluvela ekhadini levidiyo lilawula ngokuthe ngqo umgangatho wenyama weepikseli kwisiboniso. Oku kunokuvumela ukuba kubonakaliswe amancinci amancinci ngamacandelo amancinci. Oku kunokwenzeka ukuba ixabiso leemiboniso liyeke.
Ngaloo mpawu, ithemba ukuba i-DisplayPort inokudibaniswa kwintlobo ebanzi yeemveliso ngaphandle kweembonakaliso zekhompyutha, ii-PC kunye neencwadi. Iifowuni zabathengi ezincinci zingadibanisa ikhonkco le-DisplayPort ekusebenziseni kunye nabahloli abahambelanayo.
Emuva kulandelelana
Nangona iimpawu ze-DisplayPort okwangoku azibandakanyi nayiphi na uphawu lokutshintshana oluhambelanayo phakathi kwekhebula lezinto ezixhamlayo kunye nezixhumo, umgangatho ungabiza inkxaso kwiimilinganiselo zokudala ezibandakanya i-VGA, i-DVI ne-HDMI. Konke oku kuya kufuneka kulandelwe nge-adapters zangaphandle. Kuya kuba yinkimbinkimbi ngakumbi kune-adapter ye-DVI-to-VGA yesitayela kodwa isekwi-cable encinane.
