He aha ka refresh rate?

ʻO ka mea mua e pono ai mākou e hoʻokumu "He aha ke ʻano o ka refresh rate?"ʻO ka mea pōmaikaʻi ʻaʻole paʻakikī loa.ʻO ka helu hōʻano hou ka helu o ka hōʻike ʻana i ke kiʻi i hōʻike ʻia i kekona.Hiki iā ʻoe ke hoʻomaopopo i kēia ma ka hoʻohālikelike ʻana iā ia me ka frame rate i nā kiʻiʻoniʻoni a i ʻole nā ​​pāʻani.Inā paʻi ʻia kahi kiʻiʻoniʻoni ma 24 mau kiʻi i kēlā me kēia kekona (e like me ke kiʻiʻoniʻoni maʻamau), a laila hōʻike ka ʻike kumu i nā kiʻi like ʻole 24 i kēlā me kēia kekona.Pēlā nō, hōʻike ʻia kahi hōʻike me ka helu hōʻike o 60Hz e hōʻike ana i 60 "frames" i kēlā me kēia kekona.ʻAʻole ia he mau papa, no ka mea, e hōʻano hou ka hōʻike i nā manawa he 60 i kēlā me kēia kekona inā ʻaʻole hoʻololi hoʻokahi pika, a hōʻike wale ka hōʻike i ke kumu i hānai ʻia iā ia.Eia nō naʻe, he ala maʻalahi ka hoʻohālikelike e hoʻomaopopo i ka manaʻo kumu ma hope o ka refresh rate.ʻO ke kiʻekiʻe o ka refresh rate no laila ʻo ia ka hiki ke mālama i kahi kiʻekiʻe kiʻekiʻe.E hoʻomanaʻo wale, ʻo ka hōʻike wale nō e hōʻike i ke kumu i hānai ʻia iā ia, a no laila, ʻaʻole hiki ke hoʻomaikaʻi i ka helu hoʻomaha kiʻekiʻe aʻe i kou ʻike inā ʻoi aku ka kiʻekiʻe o kāu refresh rate ma mua o ke kiʻekiʻe o kāu kumu.

No ke aha he mea nui?

Ke hoʻohui ʻoe i kāu mea nānā i kahi GPU (Graphics Processing Unit/Graphics Card) e hōʻike ka mea nānā i nā mea a ka GPU e hoʻouna aku ai iā ia, i kēlā me kēia kiʻi kiʻi e hoʻouna ai iā ia, ma lalo a i ʻole ka palena kiʻekiʻe o ka nānā.ʻO ka wikiwiki o ke kiʻi kiʻi e hiki ai ke hana ʻia ma ka pale me ka maʻalahi (Fig 1), me ka hoʻemi ʻana o ka motion blur.He mea koʻikoʻi kēia i ka nānā ʻana i nā wikiō wikiwiki a i ʻole nā ​​​​pāʻani.

Ka helu hoʻomaha a me ka pāʻani

Hāʻawi ʻia nā pāʻani wikiō āpau e nā lako kamepiula, ʻaʻole pili i kā lākou paepae a i ʻole nā ​​kiʻi.ʻO ka hapa nui (ʻoi loa ma ka PC platform), kuha ʻia nā kiʻi i ka wikiwiki e like me ka hiki ke hana ʻia, no ka mea e unuhi pinepine kēia i kahi pāʻani maʻalahi a maikaʻi.E emi ana ka lohi ma waena o kēlā me kēia kiʻi a no laila e liʻiliʻi ka lag hoʻokomo.

ʻO kahi pilikia e hiki mai ana i kekahi manawa, ʻo ia ke hoʻololi wikiwiki ʻana o nā kiʻi ma mua o ka wikiwiki o ka hōʻike ʻana.Inā loaʻa iā ʻoe kahi hōʻike 60Hz, kahi e hoʻohana ʻia nei e pāʻani i kahi pāʻani e hāʻawi ana i nā kiʻi 75 i kēlā me kēia kekona, hiki iā ʻoe ke ʻike i kahi mea i kapa ʻia ʻo "screen tearing".Hana ʻia kēia no ka mea ʻo ka hōʻike, ka mea e ʻae i ka hoʻokomo ʻana mai ka GPU i nā manawa maʻamau, e hopu paha i ka hāmeʻa ma waena o nā papa.ʻO ka hopena o kēia, ʻo ia ka haʻihaʻi ʻana o ka pale a me ka neʻe ʻole ʻana.Nui nā pāʻani e ʻae iā ʻoe e hoʻopaʻa i kāu frame rate, akā ʻo ia ka mea ʻaʻole ʻoe e hoʻohana i kāu PC i kona hiki piha.No ke aha e hoʻolilo ai i ke kālā i nā mea hou loa a me nā mea nui loa e like me GPU a me CPUs, RAM a me SSD drive inā ʻoe e hoʻopau i kā lākou hiki?

He aha ka hopena i kēia, e noʻonoʻo paha ʻoe?ʻO ka helu hoʻomaha kiʻekiʻe.ʻO kēia ke ʻano o ke kūʻai ʻana i kahi 120Hz, 144Hz a i ʻole kahi nānā kamepiula 165Hz.Hiki i kēia mau hōʻike ke hoʻopaʻa i nā kiʻi 165 i kēlā me kēia kekona a ʻoi aku ka maʻalahi o ka pāʻani.ʻO ka hoʻonui ʻana mai 60Hz a i 120Hz, 144Hz a i ʻole 165Hz kahi ʻokoʻa ʻike loa.He mea ia e ʻike pono ai ʻoe iā ʻoe iho, a ʻaʻole hiki iā ʻoe ke hana i kēlā me ka nānā ʻana i kahi wikiō o ia mea ma kahi hōʻike 60Hz.

Adaptive refresh rate, akā naʻe, he ʻenehana ʻokiʻoki hou i lilo i mea kaulana loa.Kāhea ʻo NVIDIA i kēia G-SYNC, ʻoiai ʻo AMD i kapa iā ia ʻo FreeSync, akā ʻo ka manaʻo kumu.ʻO kahi hōʻike me G-SYNC e nīnau i ke kāleka kiʻi i ka wikiwiki o ka hāʻawi ʻana i nā kiʻi, a hoʻoponopono i ka helu hoʻomaha e like me ia.E hoʻopau kēia i ka uhae ʻana o ka pale ma kēlā me kēia pākuʻi a hiki i ka helu hoʻomaha kiʻekiʻe o ka nānā.ʻO G-SYNC kahi ʻenehana e uku ai ʻo NVIDIA i kahi uku laikini kiʻekiʻe a hiki iā ia ke hoʻohui i nā haneli kālā i ke kumukūʻai o ka monitor.ʻO FreeSync ma ka ʻaoʻao ʻē aʻe he ʻenehana open source i hāʻawi ʻia e AMD, a hoʻohui wale i kahi kālā liʻiliʻi i ke kumukūʻai o ka monitor.Hoʻokomo mākou ma Perfect Display iā FreeSync ma kā mākou mau mea nānā pāʻani āpau ma ke ʻano maʻamau.

ʻO ka ʻōlelo a nā mea pāʻani

Ke nīnau ʻia e pili ana i nā mākaʻikaʻi, ʻōlelo nā mea pāʻani āpau e hoʻohana lākou i ka liʻiliʻi o 144Hz no kā lākou hoʻonohonoho.Hiki i nā mea pāʻani ke hana wikiwiki i nā loli o ka pāʻani a hōʻemi pū i ka motion blur e hiki ke hoʻohuli i nā kiʻi i hōʻike ʻia.

Ke kamaʻilio nei e pili ana i ka hoʻonā, ʻōlelo lākou a pau he 144Hz refresh rate (a i ʻole ma luna) kekahi o nā mea nui i ke koho ʻana i kahi nānā pāʻani.ʻO kekahi mea nui ʻo ka hoʻonā.ʻO ka hoʻonā kaulana loa ma waena o nā mea pāʻani ʻo 1080p no ka mea maʻalahi ia e kiʻi i kahi kiʻekiʻe kiʻekiʻe a no laila e pōmaikaʻi ʻoe mai ka helu hoʻomaha kiʻekiʻe.

Ke kūʻai nei i kahi nānā pāʻani pāʻani hou, pono ʻoe e noʻonoʻo i mua.Pono ʻoe e manaʻo no 1440p inā loaʻa iā ʻoe ke kālā no ka mea ʻoi aku ka maikaʻi o ka hoʻopukapuka ʻana a hiki ke loaʻa iā ʻoe nā kumukūʻai kiʻekiʻe.Maikaʻi ka hoʻonā 1080p inā he 24 iniha ka nui o ka pale.No ka nānā ʻana o 27-35 iniha, pono ʻoe e hele no 1440p a no nā mea āpau ma luna, ʻo 4K UHD ka waiwai maikaʻi loa.
