Abaqaphi abanezixazululo ze-4k basakazeke kakhulu futhi akunakugwenywa ukuthi bazoba yizinga lezimboni ngesikhathi esifushane kakhulu, badedele i-Full-HD esivele yaziwa ngemuva, ngenxa yalesi sizathu i-Apple iyazi ukuthi isinyathelo esilandelayo uku sekela laba baqaphi kumakhompyutha akho. Kodwa-ke, kuze kube manje, ikakhulukazi uhla lweMacBook, ngokufakwa kokuxhuma kweThunderbolt 2, bathole ukusekelwa okugcwele kwalolu hlobo lwabaqaphi, ngalokhu ngisho ukuthi manje ngama-Broadwell-U CPU nama-GPU amasha ahlanganisiwe Izinqumo ezingama-3840 × 2160 zingakhonjiswa ngezinga lokuvuselela isikrini elingu-60Hz lapho lixhunywe kusetshenziswa imininingwane ye-DisplayPort 1.2 esivele ifakiwe kuThunderbolt 2.
Ngakolunye uhlangothi ngaphambili ngobuciko be-Haswell CPU, lokhu kuxhuma kufakwe ku-30Hz ukugcina isixazululo esifanayo, ngisho naku-24Hz uma ngabe kwenziwa ngoxhumano lwe-HDMI 1.4, into okusobala ukuthi ayanele kuzo zonke izinhlobo zokusetshenziswa ngaphandle kokuthi sinikezele ngesikrini okukhulunywa ngaso kuphela ekukhiqizweni kwama-movie.
Into ethakazelisa kakhulu ngalolu daba ukuthi ikhasi lezincazelo ze-Apple lisitshela ukuthi iMacBook Air entsha ikwazi ukuxhasa kuphela ama-2560 x 1600 kubaqaphi bangaphandle uma lokhu kusebenza akulona iqiniso, ngoba empeleni bayasisekela leso sinqumo. Ngokuphambene nalokho, kwi-MacBook Pro bayakusho lokhu kungenzeka kepha futhi bachaza ukwesekwa kwesixazululo se-3840 x 2160 ku-30Hz ku-HDMI 1.4 lapho kungelona iqiniso futhi, ngoba kukhawulwe ku-24Hz. Naps unentshisekelo kumqapha wangaphandle Ukuyixhuma kwi-MacBook Air yakho entsha, kufanele uqiniseke ukuthi inokuxhumeka lokho Thobela i-DisplayPort 1.2 ejwayelekile natively.
Kuze kube manje ingxenye enhle, okuphambene nakho konke lokhu ukuthi sikhuluma ngeMacBook Air, okungukuthi, idivaysi enqunyelwe ukuthwalwa, amandla ayinto ebaluleke kakhulu ekucacisweni kwayo ngakho-ke uma sisebenzisa i-4K @ 60Hz monitor futhi ufuna ukuhlenga ku- «retina» noma izinqumo ze-HiDPI, the ukugqwayiza kuzohamba kancane futhi ngokujwayelekile uhlelo lokuqhafaza luzohudula ngokungenakugwenywa.
