Zimene Mukufunikira pa HDR

Choyamba, muyenera kukhala ndi chiwonetsero chogwirizana ndi HDR. Kuwonjezera pa chiwonetserocho, muyeneranso kukhala ndi gwero la HDR, kutanthauza zoulutsira nkhani zomwe zikupereka chithunzicho ku chiwonetserocho. Magwero a chithunzichi amatha kusiyana kuyambira pa Blu-ray player yogwirizana kapena ntchito yowonera makanema mpaka pa console yamasewera kapena PC.

Kumbukirani kuti, HDR sigwira ntchito pokhapokha ngati gwero likupereka zambiri zowonjezera zamitundu zomwe zikufunika. Mudzaonabe chithunzicho pachiwonetsero chanu, koma simudzawona ubwino wa HDR, ngakhale mutakhala ndi chiwonetsero cha HDR. Chili ngati resolution mwanjira iyi; ngati simukupereka chithunzi cha 4K, simudzawona chithunzi cha 4K, ngakhale mukugwiritsa ntchito chiwonetsero chogwirizana ndi 4K.

Mwamwayi, ofalitsa amalandira HDR m'njira zosiyanasiyana, kuphatikizapo mautumiki angapo owonera makanema, makanema a UHD Blu-ray, ndi masewera ambiri a console ndi PC.

Chinthu choyamba chomwe tiyenera kudziwa ndi chakuti “Kodi refresh rate kwenikweni ndi chiyani?” Mwamwayi sizovuta kwambiri. Refresh rate ndi kuchuluka kwa nthawi zomwe chiwonetsero chimatsitsimutsa chithunzi chomwe chikuwonetsa pa sekondi iliyonse. Mutha kumvetsetsa izi poyerekezera ndi frame rate m'mafilimu kapena masewera. Ngati filimu ijambulidwa pa mafelemu 24 pa sekondi iliyonse (monga momwe zilili mu cinema), ndiye kuti zomwe zili patsamba loyamba zimangowonetsa zithunzi 24 zosiyana pa sekondi iliyonse. Mofananamo, chiwonetsero chokhala ndi 60Hz chikuwonetsa “mafelemu” 60 pa sekondi iliyonse. Si mafelemu enieni, chifukwa chiwonetserocho chidzatsitsimutsa nthawi 60 pa sekondi iliyonse ngakhale palibe pixel imodzi yomwe imasintha, ndipo chiwonetserocho chimangowonetsa gwero lomwe lapatsidwa. Komabe, fanizoli likadali njira yosavuta yomvetsetsera lingaliro lalikulu kumbuyo kwa refresh rate. Chifukwa chake, refresh rate yayikulu imatanthauza kuthekera kogwira ntchito ndi frame rate yayikulu.

Mukalumikiza chowunikira chanu ku GPU (Graphics Processing Unit/Graphics Card) chowunikiracho chidzawonetsa chilichonse chomwe GPU imatumiza kwa icho, pamlingo uliwonse wa chimango chomwe imatumiza, pamlingo wapamwamba kapena wocheperako wa chimango cha chowunikiracho. Kuthamanga kwa chimango mwachangu kumalola kuti mayendedwe aliwonse awonekere pazenera bwino, ndi kufupika kwa mayendedwe. Izi ndizofunikira kwambiri mukaonera makanema kapena masewera mwachangu.
