Inkcazo ye-Mini DisplayPort, yintoni enokudibanisa, i-adapters

Luhlobo luni lwe-Mini DisplayPort port, sebenzisa iteknoloji, umehluko wayo kwi-HDMI ekhuphisanayo, i-VGA, i-DisplayPort. I-Mini DisplayPort port yinguqulo ye-DisplayPort eyenzelwe izixhobo eziphathekayo. Ingumkhuphisani kwi-HDMI. Inguqulelo yokuqala yomgangatho osetyenziswayo yakhutshwa ngo-2006 yiVESA. Abadali bayo bazimisele ukutshintsha i-interface ye-DVI, leyo, ngokoluvo lwabo, yayisele iphelelwe lixesha. Phantse ama-200 eefemu zamalungu eVESA abandakanyekayo ekudalweni kweDisplayPort kunye neentlobo zayo.
I-Mini DisplayPort yaphuhliswa yi-Apple. Le mveliso yabhengezwa ngo-2008. Ekuqaleni yenzelwe ukusetyenziswa kwiMacBook Pro, iMacBook Air kunye neCinema Display. Ngo-2009, i-VESA ifake esi sixhobo kumgangatho wabo. Ukuqala ngenguqulo ye-1.2, i-Mini DisplayPort ihambelana nomgangatho we-DisplayPort. Ngokuthe ngcembe, iinguqulelo ezingakumbi nezintsha zalo mgangatho zaphuma. Eyokugqibela kubo ineemfuno apho abamkeli beTV abahambelanayo bengekadalwa. Umgangatho ocatshangelwayo awukhuphisani ngokuzithemba kuphela nge-HDMI, kodwa kwakhona udlula ngokuphawulekayo kwezinye iinkalo. Yenzelwe ukuhanjiswa ngaxeshanye komfanekiso kunye nesandi. Lo mgangatho wawukhululekile kwiminyaka eyi-9 yokuqala yobukho bayo, ngokungafaniyo ne-HDMI, ehlala ingumnini. Abafowunelwa abakhoyo bangohlulwa ngokwamaqela amaninzi:

1. Ezo zisetyenziselwa ukuthumela umfanekiso.
2. Isetyenziselwa ukudibanisa izixhobo.
3. Unoxanduva lokukhetha ixesha lokuvula nokucima isibonisi.
4. Yenzelwe unikezelo lwamandla.

I-Mini DisplayPort sisidibaniso esinezikhonkwane ezingama-20. Injongo nganye kuzo iyafana nezo zifunyenwe kwi-DisplayPort. Xa ukhetha ikhebula, kufuneka uhlawule ingqalelo ukuba yeyiphi izinga eliphezulu lokudlulisa idatha enokuxhasa. Ngamnye kubo ubonisa inguqu yomgangatho ohambelana nawo. Ukusetyenziswa kwesi siqhagamshelo kuya kuthandwa kakhulu phakathi kwabavelisi bezixhobo zekhompyutha. Ngokukodwa, i-AMD kunye neNvidia bakhuphe amakhadi evidiyo aneMini DisplayPort. Le ntambo inezibalo zilandelayo:

1. Izinga lokudluliselwa kwedatha yi-8.64 Gbps. Oku yimfuneko yomgangatho we-1.0 wenguqulo.Ku-1.2, ifikelela kwi-17.28 Gbps. 2.0 sele yamkelwe, apho iimfuno ziphezulu kakhulu.
2. Ubunzulu bombala ukuya kuma-48 bits kusetyenziswa. Kule meko, itshaneli nganye ine-6 ​​ukuya kwi-16 bits.
3. Isitishi esisibhozo se-24-bit audio ihanjiswa ngereyithi yesampulu ye-192 kHz.
4. Kukho inkxaso yeYCbCr kunye neRGB (v1.0), ScRGB, DCI-P3 (v1.2), Adobe RGB 1998, SRGB, xvYCC, RGB XR.
5. Isebenzisa inkqubo yoKhuseleko lweDisplayPort (DHCP) yokuchasana ne-piracy usebenzisa i-AES 128-bit encryption. Kuyenzeka kwakhona ukusebenzisa HDCP uguqulelo encryption 1.1.
6. Kukho inkxaso ukuya kuthi ga kwi-63 yeaudio kunye nevidiyo ngemisinga ngaxeshanye. Oku kuxhasa ukwahlulwa kweepakethi ngexesha.
7. Imiqondiso ethunyelwayo ifakwe ngekhowudi ngendlela yokuba kuzo zonke iibhithi ezisi-8 zolwazi oluluncedo kukho iibhithi ezi-2 zolwazi lwenkonzo. Le algorithm ikuvumela ukuba udlulise i-80% yedatha malunga nomthamo opheleleyo.
8. Ibonelela ngokusetyenziswa kwesiginali yevidiyo ye-3D kunye nesantya sokuhlaziya se-120 Hz.

Iimfuno ezidwelisiweyo zihambelana nomgangatho owamkelwe ngokubanzi. Iinguqulelo ezintsha ngoku ziyasetyenziswa ezibeka iimfuno eziphezulu kwi-Mini DisplayPort.

Umahluko kwi-DisplayPort kunye ne-HDMI

Kwi-Mini DisplayPort, ngokungafaniyo ne-DisplayPort, akukho latch yomatshini elungisa ngokuqinileyo umdibaniso. Le nguqulo iphathwa ngakumbi kwaye yenzelwe ukusebenza ngezixhobo eziphathwayo. Ngokungafaniyo ne-HDMI, ukusetyenziswa kwe-Mini DisplayPort ayifuni iimfuno ezibalulekileyo ezinjalo. Kwelinye icala, ayinazo iinketho ze-firmware. Izibuko ekuthethwa ngalo likuvumela ukuba ulawule iziboniso ezininzi ngexesha elinye ukusuka kwizibuko elinye. Inika umboniso womgangatho ophezulu kune-HDMI. Inguqulelo yangoku yomgangatho ibonelela ngekhwalithi yevidiyo ye-8K enezinga eliphezulu lokuhlaziya isikrini. I-HDMI ayiboneleli ngaxeshanye kwimifanekiso kwimiboniso emininzi, kwaye i-Mini DisplayPort ivumela ukuba kusetyenziswe iimonitha ze-4 ngale ndlela. Olunye uphuhliso lweMini DisplayPort yiThunderbolt, eyadalwa yi-Apple kunye ne-Intel. Iya kuxhasa iimpawu zangaphambili kwaye iya kuba nako ukongezelela ukusebenza ngePCI Express. I-Micro DisplayPort ikhutshiwe. Yenzelwe ezo zixhobo ezisebenzisa i-ultra-compact connectors. Ngokuqhelekileyo zisetyenziswa kwii-smartphones kunye neetafile. Xa kuthelekiswa neVGA, DVI kunye neLVDS, kufuneka kuqatshelwe ukuba lo mgangatho ukhululekile. Uhlala ephucula. Olu hlobo lwekhebula lune-immunity ephezulu yengxolo. I-VGA, i-DVI kunye ne-LVDS ayinakuxhasa iziboniso ezininzi ngexesha elinye. Ukuphumelela kwabo kuncinci kakhulu. I-Mini DisplayPort iyakwazi ukulungelelanisa umgangatho wevidiyo edlulisiweyo ngokuhambelana nomgama wokuhanjiswa kwesignali. Ukuphakama kwayo, umgangatho ophantsi womgangatho unokulindelwa, kodwa nakulo mzekelo uhlala uphezulu kakhulu. Uthini umahluko phakathi kweDisplayPort mini kunye neDisplayPort, ukusuka kwiHDMI, VGA, DVI, leliphi izibuko elingcono, umahluko phakathi kweziphumo: https:

Indlela yokudibanisa izixhobo ngeMini DisplayPort

Ukudibanisa izixhobo nesi sidibanisi, kufuneka uqwalasele oku kulandelayo:

1. Kufuneka uthathele ingqalelo ukufumaneka kwamazibuko afanelekileyo. Ukuba azikho, ke ukusetyenziswa kwee-adapters kunokunceda.
2. Kuyimfuneko ukuqwalasela ngokuhambelana nomgangatho wentambo eyenziwe. Kufuneka ihambelane neenguqulelo zezihlanganisi ezifanelekileyo.
3. I-Mini DisplayPort inokusingatha amanqanaba ahlukeneyo omfanekiso kunye nomgangatho wesandi. Iyakwazi ukubonisa ividiyo ukuya kuthi ga kwi-8K.
4. Ubude bentambo yokudibanisa kufuneka buthathelwe ingqalelo. Ukuba ayidluli kwi-3 m, ke kungcono ukusebenzisa i-Mini DisplayPort. Ukuba ifikelela kwi-10m, kungcono ukusebenzisa i-HDMI interface.
5. Qwalasela ukuba zingaphi iimonitha ekufuneka uzidibanise. Ukuba akukho ngaphezu kwezine, ngoko ikhebula ekuthethwa ngalo liya kwenza.

I-Mini DisplayPort iya kukunceda ungabukeli ividiyo ekumgangatho ophezulu kuphela, kodwa ukonwabele isandi esihle kwimidlalo. Iintlobo ezintathu zeDisplayPort – esemgangathweni, encinci, encinci:

Iiadaptha

Ukusetyenziswa kwee-adapters kukuvumela ukuba usombulule ingxaki kwiimeko apho izixhobo ezisetyenzisiweyo zingenalo umdibaniso ofunekayo. Kufuneka kuthathelwe ingqalelo ukuba ukusetyenziswa kwabo kunciphisa umgangatho wokuhanjiswa komqondiso. Kukho iiadaptha ezikuvumela ukuba udibanise ilaptop kwiVGA, DVI, HDMI. Baya kukuvumela ukuba udibanise kwiintlobo ezininzi zezikrini ezisetyenzisiweyo. Iiadaptha ziyasebenza okanye ziyasebenza. Abangaphambili bayakwazi ukuhambisa ividiyo esemgangathweni ophezulu (umzekelo, ngesisombululo se-3840×2160) phezu kobude bekhebula ukuya kwi-2 yeemitha. Ukuba umgama unyuka ukuya kwiimitha ezili-15, ngoko izinga lomgangatho owamkelekileyo liya kuba liphantsi kakhulu. Kule meko, iya kubonelela ngokujonga kwi-1080p. Ukusetyenziswa kweziqhagamshelo ezisebenzayo kukuvumela ukuba ukwandise uluhlu oluphezulu loqhagamshelo. Ngokomzekelo, kule meko, kuya kwenzeka ukuba kuqinisekiswe umgangatho wokubonisa we-2560 × 1600 kumgama weemitha ezingama-25.
