• HDMI yothamanga kwambiri - mtundu uwu wa chingwe ndiwofunikira kwambiri kwa iwo omwe amagwira ntchito mwaluso ndi zithunzi kapena amakonda kuonera mafilimu / kusewera masewera pa Ultra HD resolution (4096 × 2160). Komabe, kuthandizira kwa Ultra HD pa chingwechi sikulakwitsa pang'ono, chifukwa momwe makanema ogwiritsira ntchito makanema amatha kutsika mpaka 24 Hz, yomwe ndi yokwanira kuwona kanema, koma mawonekedwe a masewerawa amakhala opunduka kwambiri;
• HDMI & Ethernet yothamanga kwambiri - zonse zofanana ndi za analogue kuchokera mundime yapitayi, koma nthawi yomweyo zidawonjezera thandizo la 3D-video ndi intaneti.

Zingwe zonse zimakhala ndi ntchito yapadera - ARC, yomwe imakupatsani mwayi wofalitsa mawu pamodzi ndi kanema. M'mitundu yamakono ya zingwe za HDMI, pali thandizo laukadaulo lonse la ARC, chifukwa chomwe mawu ndi makanema amatha kufalikira kudzera mu chingwe chimodzi, popanda chifukwa cholumikizira mahedifoni ena owonjezera.

Komabe, mu zingwe zakale, ukadaulo uwu sukwaniritsidwa. Mutha kuwonera kanema ndikumva mawu nthawi yomweyo, koma mawonekedwe ake sadzakhala abwino (makamaka polumikiza kompyuta / laputopu ku TV). Kuti muthane ndi vutoli, muyenera kulumikiza adapter yapadera.

Zingwe zambiri ndizopangidwa ndi mkuwa, koma kutalika kwake sikokwanira kuposa 20 metres. Pofuna kufalitsa zambiri pamtunda wautali, ma subtypes amtambo awa amagwiritsidwa ntchito:

• CAT 5/6 - amagwiritsa ntchito kufalitsa zambiri pamtunda wa 50 metres. Kusiyana kwamatembenuzidwe (5 kapena 6) sikukutenga gawo lapadera pakusintha kwa mtunda ndi mtunda;
• Coaxial - imakupatsani mwayi wosamutsa deta pamtunda wamamita 90;
• Fibre optic - ikufunika kufalitsa deta pamtunda wa mita 100 kapena kupitilira.

Makabati a DisplayPort

Pali mtundu umodzi wokha wa chingwe, womwe lero uli ndi mtundu wa 1.2. Mphamvu zowonetsera za DisplayPort ndizapamwamba pang'ono kuposa HDMI. Mwachitsanzo, chingwe cha DP chitha kupatsira vidiyo yokhala ndi mapikisheni 3840x2160 popanda mavuto, pomwe sichikutaya mawonekedwe akusewera - imakhalabe yabwino (osachepera 60 Hz) komanso imathandizira kutumiza kwa vidiyo ya 3D. Komabe, imatha kukhala ndi mavuto ndi kufalitsa kwamtundu, monga palibe ARC yomangidwa, kuphatikiza apo, zingwe za DisplayPort sizigwirizana ndi mayankho pa intaneti. Ngati mukufunika kufalitsa mavidiyo ndi makanema nthawi yomweyo kudzera pa chingwe chimodzi, ndiye kuti ndibwino kusankha HDMI, chifukwa chifukwa DP iyenera kugula kuwonjezera pamutu wapadera.

Zingwe zoterezi zimatha kugwira ntchito pogwiritsa ntchito ma adapter oyenera, osangolumikizana ndi DisplayPort okha, komanso HDMI, VGA, DVI. Mwachitsanzo, zingwe za HDMI zimatha kugwira ntchito ndi DVI popanda mavuto, chifukwa DP imadula mpikisano wake mogwirizana ndi zolumikizira zina.

DisplayPort ili ndi mitundu iyi ya chingwe:

• Passive. Ndi iyo, mutha kusamutsa chithunzicho ngati pixel 3840 × 216, koma kuti chilichonse chitha kugwira ntchito pafupipafupi (60 Hz - yabwino), muyenera kukhala ndi chingwe kutalika kosaposa 2 metres. Makabati okhala ndi kutalika pamtunda kuchokera pa 2 mpaka 15 metres amatha kubala makanema 1080p okha osatayika muyezo wozungulira kapena 2560 × 1600 ndi kutayika pang'ono muyezo wozungulira (pafupifupi 45 Hz mwa 60);
• Yogwira Imatha kutumiza chithunzi cha kanema wa pixels 2560 × 1600 pamtunda wa mamita 22 popanda kutaya mtundu wamasewera. Pali zosintha zopangidwa ndi fiber optic. M'malo omaliza, mtunda wopatsirana popanda kuwonongeka kwaumoyo umachulukira mpaka 100 metres kapena kupitirira.

Komanso zingwe za DisplayPort zimakhala ndi kutalika kokhako kogwiritsidwa ntchito kunyumba, komwe sikungathe kupitirira 15 metres. Zosintha mwa mtundu wa mawaya a fiber optic, etc. DP sichoncho, chifukwa chake ngati mukufuna kusamutsa deta ndi chingwe pamtunda wautali wa 15, mudzayenera kugula zingwe zapadera kapena kugwiritsa ntchito matekinoloje ampikisano. Komabe, zingwe za DisplayPort zimapindula chifukwa chogwirizana ndi zolumikizira zina komanso kusamutsa zinthu zowoneka.

Nyimbo za zomvera ndi makanema

Pakadali pano, zolumikizira za HDMI zimatayikiranso chifukwa sizigwirizana ndi njira zowerengera mavidiyo ndi zomvetsera, chifukwa chake, zotulutsira zambiri ndizotheka pokhapokha pokhapokha. Izi ndizokwanira kwa ogwiritsa ntchito wamba, koma kwa akatswiri ochita masewera olimbitsa thupi, osintha mavidiyo, zithunzithunzi ndi opanga za 3D izi sizingakhale zokwanira.

DisplayPort ili ndi mwayi woonekeratu pankhaniyi, monga kutulutsa kwazithunzi mu Ultra HD ndikutheka nthawi yomweyo pazowunika ziwiri. Ngati mukufuna kulumikiza owunika anayi kapena kupitilira apo, ndiye kuti muyenera kuchepetsa kuyika kwa onse kukhala Full kapena HD yokha. Komanso, phokoso lidzakhala lopanga lililonse laowunikira.

Ngati mumagwira bwino ntchito ndi zojambula, makanema, zinthu za 3D, masewera kapena ziwerengero, ndiye kuti muthani makompyuta / ma laputopu omwe ali ndi DisplayPort. Zabwinonso, gulani chida ndi zolumikizira ziwiri nthawi imodzi - DP ndi HDMI. Ngati ndinu wosuta wamba yemwe safuna china chake "kupitilira" pa kompyuta, mutha kuyimilira pa Model ndi doko la HDMI (zida zotere, monga lamulo, ndizotsika mtengo).
