Kodi cholumikizira cha DisplayPort ndi chiyani, chikuwoneka bwanji komanso chifukwa chake chimagwiritsidwa ntchito

Chojambulira cha DisplayPort (DP) lero ndi mawonekedwe otchuka, omwe amagwiritsidwa ntchito kawirikawiri omwe amapangidwa kuti agwirizane ndi zamakono zamakono, ma TV, oyang’anira. Mawonekedwe opita patsogolo, amakono amakulolani kuti mupeze kulumikizana kwapamwamba mukalumikiza zida zomvera kapena makanema.
Komabe, nthawi zambiri, DisplayPort imagwiritsidwa ntchito ndi ogwiritsa ntchito pakafunika kulumikiza zowonetsera zosiyanasiyana, zowunikira kapena zisudzo zakunyumba, ma TV ku PC yakunyumba (desktop) kapena laputopu. Pogwiritsa ntchito mawonekedwe amakono, wogwiritsa ntchito amatha kusamutsa zinthu zadijito, zomwe zili ku zida za gulu lachitatu pomwe akukhalabe ndi mawonekedwe apamwamba (mpaka 8K).

Kufotokozera kwa doko ndi kukula kwake

Masiku ano, ogwiritsa ntchito ambiri, nthawi zambiri, amagwiritsa ntchito DP ngati kuli kofunikira kulumikiza zitsanzo zamakono ku PC. Kuphatikiza apo, doko ili ndilabwino nthawi yomwe muyenera kulumikiza TV pakompyuta. Nthawi zina, DisplayPort (DP) imagwiritsidwa ntchito mwachangu polumikiza ma acoustics kapena zida zina zapa media. Kuphatikiza pa zojambulajambula, dokoli limatha kutumiza zomvera ndi zida zomvera ku zida zina. Chifukwa cha kugwiritsa ntchito DP, wogwiritsa ntchito amatha kulumikiza zowunikira zambiri ku PC yake nthawi imodzi. Tiyenera kuzindikira kuti chifukwa cha bandwidth yapamwamba ya madoko, kusamutsidwa kwa zithunzi kwa oyang’anira ndizotheka pazosankha zazikulu zomwe zimaloledwa lero (2K, 4K).

Ndi mitundu yanji ya zolumikizira za DisplayPort zomwe zilipo

Pali mitundu ingapo yolumikizira yomwe imabwera ndi DisplayPort. Zolumikizira izi ndi:

1. Standard (kukula kwathunthu) . Monga lamulo, pafupifupi mitundu yonse yamakono ya ma TV, makompyuta aumwini, ma laputopu ali ndi mawonekedwe otere. Mpaka pano, ndi mtundu uwu wa mawonekedwe omwe adalandira kugawidwa kwakukulu ndipo amagwiritsidwa ntchito kwambiri.
2. Mini DP . Ndi mtundu wocheperako wa doko lowonekera nthawi zonse. Zolumikizira zamtunduwu nthawi zambiri zimakhala ndi zida zonyamula, zam’manja. Mwachitsanzo, mitundu yamakono ya mapiritsi ndi ma netbook nthawi zambiri imakhala ndi madoko a mini DP.

Sikuti zolumikizira zonse za mini DP zili ndi zida zapadera, kukonza (kutsekereza) zinthu. Komabe, pamawonekedwe onse amtundu wamtundu uliwonse, chinthu chotsekera choterechi chimakhalapo.

Mafotokozedwe a cholumikizira

Chimodzi mwazinthu zowonetserako ndi magetsi awo otsika komanso kusokoneza kochepa. Poyerekeza ndi DVI wamba, DP yamakono ili ndi bandwidth yabwinoko (pafupifupi kawiri). Nthawi yomweyo, ziyenera kuzindikirika kuti mawonekedwe ang’onoang’ono a doko lowonetsera mumiyeso yake ndi pafupifupi kakhumi kakang’ono kuposa cholumikizira chamtundu wa DVI.
Sizofunikira kunena kuti DisplayPort imatha kutumiza ma siginecha amakanema nthawi imodzi, komanso mtundu wamawu. Kuchulukitsa kwamitundu yoyambirira ya DP kunali 9Gbps. Kusintha kwamitundu yatsopano yamadoko otere kumasiyanasiyana mpaka 29 Gb / s.

Zachidziwikire! Kutalika konse kwa chingwe cha DP chomwe chimagwiritsidwa ntchito kulumikiza ku PC ndikutumiza chizindikiro sichiyenera kupitirira mamita 15. Panthawi imodzimodziyo, chingwe chachitali (15 m) chimatha kutumiza chithunzi mu khalidwe la Full HD. Kuti mupeze chigamulo chachikulu cha chithunzi chofalitsidwa, tikulimbikitsidwa kugwiritsa ntchito zingwe zazing’ono za DP (mpaka 3 m).

Zolumikizira za DP zili ndi mapini 20 ndipo zimatha kutumizira mauthenga pogwiritsa ntchito mayendedwe anayi. Dziwani kuti ali Komanso okonzeka ndi njira otchedwa luso njira (mpaka 800 Mbps). Kusintha kwakukulu kotheka kwa chiwonetsero cha doko la DP (mtundu 1.4) kufika 7680×4320.

Ubwino ndi kuipa kwa doko

Ma doko owonetsera (DP) ali ndi zabwino zonse komanso zovuta zake. Ubwino wa mawonekedwewa ndi awa:

• kukhalapo kwa cholumikizira chapadera ndi mwayi wodzitsekera;
• imasunga deta motetezeka;
• yogwirizana ndi mawonekedwe apamwamba;
• oyenera kugwirizana munthawi yomweyo oyang’anira angapo nthawi imodzi;
• kukhalapo kwa dongosolo losavuta lokonzekera zolumikizira;
• yokhala ndi njira yothamanga kwambiri, yowonjezera yowonjezera.

Kuipa kwa madoko owonetsera kumaphatikizapo kuti sangathe kugwira ntchito mokwanira ndi chingwe chotalika kwambiri (kuti atumize chithunzi chapamwamba ndi kuthetsa, tikulimbikitsidwa kugwiritsa ntchito chingwe chosapitirira 3 mamita). Kuphatikiza apo, masiku ano ngakhale zida zonse zamakono sizithandizira ntchito ndipo zili ndi cholumikizira ichi. Komabe, kulumikiza ma multimedia ndi zida zina zomwe zilibe cholumikizira chamakono cha DisplayPort, mutha kugwiritsa ntchito ma adapter apadera. Pakati pa ogwiritsa ntchito, zida zapadera zimafunidwa kwambiri – ma adapter kuchokera ku DP kupita ku zolumikizira monga HDMI, kapena ku VGA yodziwika bwino.

Zosankha Zosankha Chingwe za DisplayPort

Mitundu yonse yosiyanasiyana ya zingwe za DP imagwirizana ndi zida zomwe zili ndi doko lowonetsera. Kugwirizana ndi kuyanjana sikukhudzidwa ndi mtundu wa cholumikizira chogwiritsidwa ntchito, kapenanso mulingo wa certification. Chifukwa chake, mukamagwiritsa ntchito chingwe chilichonse cha DisplayPort, chifukwa chogwiritsa ntchito njira imodzi yolumikizira, zonse zomwe zimaperekedwa ndi mawonekedwewa zidzasungidwa.

Ndi njira ziti zomwe ziyenera kutsatiridwa posankha chingwe chowonetsera (DP)?

Pakusankha zingwe za DP, ziyenera kuganiziridwa kuti zitha kukhala ndi magawo osiyanasiyana a liwiro lotumizira chidziwitso choyambirira. Ponseponse, doko lowonetsera litha kugwira ntchito m’njira zinayi zotumizira zidziwitso: HBR3, HBR2, HBR, ndi RBR. Pali mitundu ingapo ya ziphaso (chitsimikizo choterocho sichifunikira, ndipo zingwe zomwe zadutsamo zimayikidwa molingana), zomwe zingagwiritsidwe ntchito kudziwa momwe chingwecho chimagwirira ntchito. Malinga ndi miyezo yovomerezeka yovomerezeka, zingwe zomwe zimagwiritsidwa ntchito kulumikiza madoko ndi:

1. Standard . Kutha kusamutsa zambiri mwachangu. Kuthamanga kwa HBR kumafika 10 Gb / s, ndi HBR2 – osapitirira 21.60 Gb / s.
2. Zingwe za RBR . Amasiyanitsidwa ndi kutsika kwachidziwitso chotsika (osapitirira 6.48 Gbps).
3. DP8K chingwe Kutha kutumiza deta pa liwiro lalikulu (osapitirira 32.40 Gbps).

Malinga ndi muyezo wa DisplayPort, kutalika (kutanthauza mtengo wake wapamwamba) wa chingwe cha data chomwe chimagwiritsidwa ntchito sichimatanthauzidwa. Komabe, molingana ndi miyezo yomwe idakhazikitsidwa pa DisplayPort 1.2, mawonekedwe amtunduwu ali ndi zofunikira zochepa potengera kukula ndi kusamutsa kwa chidziwitso choyambirira (zingwe zofikira 2 metres kutalika ziyenera kuthandizira kuthamanga mpaka 21.6 Gb / s). https://youtu.be/7n9IQ_GpOlI

General zofunika ndi malamulo kugwirizana

Zatsopano komanso zodziwika pang’onopang’ono pakati pa ogwiritsa ntchito ndi mawonekedwe a DisplayPort, omwe lero amatengedwa kuti ndi amodzi mwa opikisana nawo amakono komanso otchuka a HDMI cholumikizira. Chifukwa cha kugwiritsa ntchito DP, wogwiritsa ntchito amatha kulumikiza zowunikira zingapo ku PC yake nthawi imodzi. Kuphatikiza apo, mawonekedwewa amatha kuthandizira kusamutsa zithunzi zokhala ndi kusamvana kwakukulu (4K), komanso mafayilo amakanema mumtundu wa 3D. Ndizofunikira kudziwa kuti DP imabwera mumitundu iwiri – yokhazikika ndi mini. Chiwembu cholumikizira kompyuta, laputopu ndi oyang’anira, TV, kapena makanema ena, zida zomvera ndizofanana ndikugwiritsa ntchito zingwe wamba za HDMI. Mukungoyenera kulumikiza chipangizo chimodzi ndi china pogwiritsa ntchito chingwe cha DP. Ngati polojekiti yanu kapena TV ilibe cholumikizira ichi,
Kupyolera mu DP ku kompyuta, mukhoza kulumikiza zowunikira ziwiri zosiyana. Kuti muchite izi, muyenera kuwonetsetsa kuti khadi ya kanema yomwe idayikidwa pa PC imathandizira DP, ndipo chowunikiracho chimagwirizana ndi ntchito yosinthira deta yamitundu yambiri (MST DisplayPort). Kenako polojekiti yoyamba iyenera kulumikizidwa ndi chingwe ku DisplayPort, yomwe ili pa PC. Kutulutsa kwa DP koyang’anira koyamba kumalumikizidwa ndi chingwe kuyika kwa DisplayPort ya chowunikira chachiwiri. Pa polojekiti yoyamba, muyenera kuyambitsa mawonekedwe a DisplayPort, ndipo yachiwiri, yomwe ili yomaliza mu unyolo wolumikizira, muyenera kuyimitsa m’malo mwake. Poyerekeza ndi mawonekedwe ena, DisplayPort ikungoyamba kutchuka pakati pa ogwiritsa ntchito. Tsopano imagwiritsidwa ntchito makamaka kulumikiza ma PC amakono, apamwamba kumitundu yatsopano yowunikira yomwe ili ndi DP. Ndizofunikira kudziwa kuti opanga makhadi amakanema amakonzekeretsa zambiri mwazinthu zawo, zomwe ndi zamitundu yodziwika bwino, ndi mawonekedwe awa. Kuphatikiza apo, dokoli limagwiritsidwa ntchito mwachangu ngati pakufunika kukhazikitsa zisudzo kunyumba. Malinga ndi akatswiri ena, ukadaulo wa DisplayPort utha kukhala wotsogola mtsogolomo chifukwa cha kutchuka komanso kugwiritsa ntchito mulingo wa 8K wotumizira zithunzi.
