Filip Novotny Apple sabata ino idavumbulutsa mtundu watsopano wapamwamba kwambiri wa iMac wokhala ndi mawonekedwe owonda kwambiri omwe akutsatsa ngati "5K Retina." Ichi ndiye chiwonetsero chapamwamba kwambiri padziko lonse lapansi, ndichifukwa chake ena ayamba kuganiza ngati iMac yatsopano ingagwiritsidwe ntchito ngati chiwonetsero chakunja kapena tingayembekezere chiwonetsero chatsopano, cha Bingu la retina. Mayankho a mafunso onsewa ndi ogwirizana kwambiri.
Ogwiritsa ntchito angapo akhala akugwiritsa ntchito chophimba chachikulu cha 21,5 ″ kapena 27 ″ iMac ngati chowunikira chakunja, mwachitsanzo, MacBook Pro kwa zaka zingapo. Pakadali pano, Apple idathandizira njirayi kudzera pa chingwe cha Thunderbolt. Malinga ndi Funsani seva mkonzi TechCrunch Komabe, njira yofananayo sizingatheke ndi retina iMac.
Izi ndichifukwa chakulephera kwaukadaulo wa Bingu la Thunderbolt. Ngakhale kubwereza kwake kwachiwiri sikutha kutengera zomwe zimafunikira pakukonza kwa 5K. Mafotokozedwe a DisplayPort 1.2 omwe Thunderbolt 2 amagwiritsa ntchito amatha "kokha" kuthana ndi 4K. Pachifukwa ichi, kulumikiza iMac ndi kompyuta ina kugwiritsa ntchito chiwonetsero chachikulu sikutheka kugwiritsa ntchito chingwe chimodzi.
Chifukwa chosowa ichi ndi chophweka - mpaka lero panalibe kufunikira kwa chisankho chachikulu chotero. Msika wamakanema a 4K akungoyamba pang'onopang'ono, ndipo miyezo yapamwamba ngati 8K ndi (osachepera ngati malonda ambiri) nyimbo zamtsogolo zakutali.
Ichi ndichifukwa chake mwina tidikirira kwakanthawi kuti chiwonetsedwe chatsopano cha Bingu. M'badwo wake wapano - womwe ukugulitsidwabe 26 CZK yodabwitsa - ndiyopanda malo pakati pa zowonetsera zamakono pazida za Apple.
Ngati Apple iganiza zokhutiritsa kudikira kwanthawi yayitali kwa ogwiritsa ntchito ndikuyambitsa m'badwo watsopano wa Thunderbolt Display, ikhala ndi njira ziwiri zomwe mungasankhe. Khalani ndi chisankho cha 4K (ndikusinthanso 4K Retina potengera malonda), kapena gwiritsani ntchito mtundu watsopano wa DisplayPort wokhala ndi nambala 1.3. Nanga bwanji pa blog yanu zikusonyeza wolemba mapulogalamu Marco Arment, izi zitheka kokha ndi kukhazikitsidwa kwa nsanja yatsopano ya Intel Skylake, yomwe idzalowe m'malo mwa mapurosesa apano a Broadwell.
Pamaso pa chiwonetsero chatsopano chakunja, iMac yokhayo mwina idzasinthidwanso. Zowonetsera za retina sizingakhale ndi mtundu wa 27 ″, koma m'malo mwake zidzawonjezedwa ku mtundu wa 21,5 ″, kutsatira chitsanzo cha MacBook Pro. (MacBook Pro yokhala ndi chiwonetsero cha retina idapezekanso mu mtundu wa 15 ″.) Malinga ndi katswiri wina Ming-Chi Kuo, mtundu wawung'ono wa iMac wokhala ndi mawonekedwe a Retina ukanakhalapo. bwerani mu theka lachiwiri la 2015.
Chabwino, ine pafupifupi sindikufuna kukhulupirira kuti TB 2 sangathe kudyetsa 5K, nanga psinjika ena deta, ine sindikudziwa interlacing mode, ine mobisa ndikukhulupirira kuti Apple adzabwera ndi luso linalake kuti kukankhira. retina kudzera mu TB yomwe ilipo pano, akadadziwiratu kuti siigwira, akadakakamiza intel kuti iwapatse ukadaulo wamabuku achaka chino, ndizopanda nzeru, tiwona, ndikukhulupirira atero. kuthetsa, chifukwa cha mtunduwo, pambuyo pa zonse, macbook olumikizidwa ndi LG kapena Samsung 4K monitor ndi yuck :).
ponena kuti apulo adayambitsa 5K, sichinapindule chilichonse kupatulapo kuti akhoza kudzitama kuti ndi bwino kuposa 4K. Zina zonse ndizoyipa chabe - kuyanjana ndi makanema a 4K, kuyanjana ndi miyezo ya 4K. Kusamvana kwakukulu kosewera masewera. Chabwino, sindikuganiza kuti pali chifukwa chimodzi cha 5K :(
Chifukwa chake ndi zithunzi :-) chifukwa ojambula akatswiri nthawi zambiri amakhala ndi ma megapixels 12-14 mu SLRs :-) sizingalowe m'malo kwa iwo :-) sindikuwona kuipa kotere pamakanema idzakhalabe yakuthwa bwino :-) Ndikumva kuti masewerawa adzayamwa, koma mac sanamangidwe kwa osewera :-)
Chinanso chomwe apulo adasankha kuchita izi ndikuti ngati ikuyenera kukhala yabwino kwambiri pakusintha kwa retina, ndiye kuti pixel imodzi ya 2560 × 1440 iyenera kukhala ndi ma pixel 4 enieni. Kotero ngati ayika 4K pamenepo, sipakanakhala kuchulukira koteroko, ndipo chachiwiri chikanakhala kuti "retina resolution" yawo idzakhala FullHD yokhayokha ... njira ina iliyonse ingakhale kuwonjezeka kwa ma pixel atatu kapena kuchepera. ... kotero zimatha kukhala ngati macbook retina pomwe chigamulo chapamwamba chakhazikitsidwa, mwachitsanzo FullHD, ndipo zojambulazo zimakhala ndi ntchito yochulukirapo kuposa momwe zimayendera bwino kwambiri pakusintha kwa retina, mwachitsanzo 3 × 1440. kufotokoza, ngati muyika 900 × 1920 pa macbook okhala ndi retina, kompyutayo imayika kaye chigamulo pafupi ndi 1200K ndiyeno imagawanika ndi kusamvana kwa retina ndipo imagwira ntchito kuti iwonetse ma pixel angati pa pixel imodzi. Zomwe sizikhalanso zochulukitsa ziwiri ... Chifukwa chake pamapeto pake, eni ake a iMac yatsopano apeza lingaliro la iMac yakale yokhala ndi kuthwa kwachitsanzo ngati lumo :-)
Ine, monga mlengi, ndikhoza kulingalira. Ndili ndi retina macbook pro ndipo sindingathe kuyamika mokwanira. gawo lowonera mu cad ndi sketchup ndilabwino ngakhale pakuwonetsa 15 ″. nanga bwanji gawo lowonera pa 2x yokulirapo komanso chiwonetsero chachikulu cha 2x? Sindidzafunikanso kusuntha kuchoka ku zojambula zina kupita ku zina monga momwe ndimachitira pawindo la FullHD.
Itha kuthetsedwa mosavuta ndi chingwe chimodzi cholumikizidwa ndi njira ziwiri za Thunderbolt 2. Sindingadabwe ngati zowonetsera ziwiri za Thunderbolt retina zidzatuluka chaka chamawa, imodzi 24 ″ yokhala ndi 4K ndi 27 ″ imodzi yokhala ndi 5K. Ndipo mac pro ndi iMac atsopano omwe angathandizire.
Zitha kuchitika m'njira zingapo monga ndidalembera apa :-) ndizokwanira kuti chowunikira cha 5K chiwoneke ngati oyang'anira awiri okhala ndi chiganizo cha 2560 × 2880 cha bingu :-) ndiye ndizotheka kukulitsa motere ndi chingwe. :-) mfundo ndi yakuti bingu siligwirizana ndi chigamulo chimenecho.
Kapenanso chingwe chachiwiri cha bingu, ndi mfundo yoti mungataye imodzi ndipo imodzi idzakhala pa polojekiti ...
Zingakhale zolakwika kwambiri kuganiza kuti apulo idzadula zipangizo zina monga izi ... Eni ake a Macbook Pro 15 ndi Retina, yomwe pakali pano ili ndi mtengo wa iMac yokhala ndi 5k resolution, sangafune 24-inch monitor, koma 27. -inch imodzi yokhala ndi 5k resolution ... ndipo koposa zonse, apulo angachepetse kufunika ngati atangoyiyika muzipangizo zatsopano zomwe zimagulitsidwa pang'ono kuyambira pomwe zidakhazikitsidwa ndipo zitha kukhala zotsika mtengo kwambiri m'tsogolomu ...
Ndi mfundo yoti idzakhala mainchesi 24 ndi 4K ndi mainchesi 27 ndi 5K, koma mukulondola :-) chifukwa 24 inchi imac tsopano ili ndi lingaliro la 1920 × 1200 :-) kotero 4K ingagwirizane ndi yabwino kwambiri pakusintha kwa retina. .
Koma ine, ndikuyembekeza kuti Apple yasunga malingaliro awo, ndikuyembekeza kuti ndili ndi chikhulupiriro choposa 95% kuti izi zichitika.
Apple ndiyosangalala kwambiri kusiya thandizo la ma MBP apano a retinoic. Ali ndi chithandizo cha 4K koma pa 30Hz okha. Kwa iwo okha, 4K pa 60Hz imatha kulumikizidwa kudzera pa zingwe ziwiri. MBA sichithanso 2K pa 4Hz, chifukwa ili ndi cholumikizira chimodzi chokha cha Thunderbolt 30. Ndipo Mac Pro imathanso kupeza 2K, koma kudzera pa 5 kapena 3 Thunderbolt 4 zolumikizira.
Sizowona :-) kuchokera ku 10.9.3. ali ndi 4k mu 60hz ;-) kapena retina yapamwamba yokhala ndi GT750m :-) ndipo ndikukayika kuti ifuna kuchita izi pazingwe zopitilira ziwiri :-)
Malinga ndi tsamba la Apple, bingu 2 limathandizira malingaliro awa:
Kuthandizira kwa 3840-by-2160 resolution pa 30Hz
Kuthandizira kwa 4096-by-2160 resolution pa 24Hz
Chifukwa chake kuthandizira kwa sw ndikokwanira ndiyeno kuchepetsedwa kwamtundu wina komwe kulumikiza 2 kukhala imodzi ndipo imalumikizidwa ndi chiwonetsero cha 4K ndi chingwe chimodzi ndipo iyenera kupita ku 60Hz.
Intel ikhoza kupanga Thunderbolt yatsopano ndi Apple nthawi iliyonse ngati chipangizo chowonjezera, sichiyenera kukhala gawo la chipset kuyembekezera mpaka 2016. yembekezera. Chifukwa chake mwina ngakhale Apple sakufuna panobe.

Mukayang'ana pansi, Multi-Stream Transport (MST) ikuwonetsa
Ine basi sindikumvetsa ngati MTS ndiye amadutsa chingwe chimodzi kapena 2 zingwe. Ndikuwopa kuti kudzera pa zingwe ziwiri, chifukwa macbook air sichimathandizidwa pamenepo ndipo ili ndi doko la Thunderbolt 2 yokha.
Kupyolera mu imodzi yokha :-) koma muyenera kukhala ndi zithunzi zamphamvu pa laputopu :-) kotero ndikuyang'anira 4K kapena 5k zipangizo zonse zidzakakamira kupatula Macbook Pro 15 yokhala ndi retina ndi zithunzi zachiwiri, mac pro ndi imac ndi 5K.
Ndizo zabwino ndiye. Apple ndiyosangalala kwambiri kudula zida zakale ndikulola makasitomala kugula zatsopano. Ndikuwopa kuti 5K sigwira ntchito ngakhale ndi MTS, 4K yokha.
Zinandichitikira kuti Apple ikhoza kupanga chiwonetsero cha 30 ″ 6K ndikutumiza ndi Mac Pro yatsopano ndili :-)
Sindikudziwa tsatanetsatane wa kayendedwe kake pankhani ya MST. Mulimonse momwe zingakhalire, kwa Displayport zotulukapo ndi 22,18 gbit pa 5K... Bingu lili ndi zotulukapo za 20 gbit pamenepo ndi 20 gbit kubwerera munthawi yeniyeni... funso ndilakuti lingasinthidwe kuti 20 gbit ibwerere mmbuyo. atha kulowanso... Mwina makamaka pa pempho la Apple :- )
Pa mphekesera za mac, pabwaloli, tsopano eni ake a mac otsika mtengo akupeza kuti makina awo 6, 8 oyambira sangagwirizane ndi mtsogolo zotheka 5K m'tsogolomu. Ambiri akuganiza, monga Marc Arment apa ndikusintha kupita ku iMac Retina ndikugulitsa mac pro. Koma mwina sizitenga nthawi yayitali, miyeso yoyamba ya retina imac idzatulutsidwa kwa anthu, ogwiritsa ntchito adzapeza kuti si ulemerero, ndipo zonse zidzakhala zofanana ndi kale ...
Monga momwe kulumikizidwa kwa MacPro (osakhala) ndi chiwonetsero cha 5K ndikodabwitsa kwambiri. Ndikaganizira kuti eni ake a MacPro mwina ndi okhawo omwe angapindule kwambiri ndi chisankho chotere.. Mwachiwonekere, wina ku Apple anapanga izi. Moni
