Hoʻohālike:JM27-165Hz
27 iniha QHD 165Hz MPRT1ms LED Monitor No ka pāʻani
Nā mea nui
- 27" me 2560x1440 QHD Resolution
- ʻO ka manawa pane MPRT 0.6ms a me 165Hz Refresh Rate
- Hōʻike Port a me 2 x HDMI pili
- ʻAʻohe haʻalulu a haehae ʻole me AMD FreeSync Technology
- Hāʻawi ka hoʻolālā frameless i ka ʻike ʻike maikaʻi
- ʻO FlickerFree a me ka ʻenehana ʻenehana haʻahaʻa
No ke aha e hoʻohana ai i nā mākaʻikaʻi 144Hz a i ʻole 165Hz?
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.
Pono au e kūʻai i kahi nānā pāʻani pāʻani G-Sync a me FreeSync?
Ma ka ʻōlelo maʻamau, koʻikoʻi nui ʻo Freesync no ka pāʻani ʻana, ʻaʻole wale no ka pale ʻana i ka haehae akā no ka hōʻoia ʻana i kahi ʻike maʻalahi.He ʻoiaʻiʻo loa kēia inā ʻoe e holo ana i nā lako pāʻani e hoʻopuka ana i nā kiʻi ʻoi aku ma mua o kāu hōʻike.
ʻO G-Sync a me FreeSync nā hoʻonā i kēia mau pilikia ʻelua ma o ka hōʻano hou ʻana i ka hōʻike ma ka wikiwiki like me nā kiʻi i hāʻawi ʻia e ke kāleka kiʻi, e hopena i ka pāʻani ʻoluʻolu a me ka waimaka ʻole.
He aha ka HDR?
Hoʻokumu nā hōʻike kiʻekiʻe-dynamic range (HDR) i nā ʻokoʻa hohonu ma o ka hana hou ʻana i kahi ʻano ʻoi aku ka ikaika o ka luminosity.Hiki i ka nānā ʻana o HDR ke hoʻomālamalama i nā hiʻohiʻona a hāʻawi i nā aka momona.ʻO ka hoʻomaikaʻi ʻana i kāu PC me kahi nānā HDR he mea kūpono inā pāʻani ʻoe i nā pāʻani wikiō me nā kiʻi kiʻi kiʻekiʻe a nānā paha i nā wikiō ma ka hoʻonā HD.
Me ka loaʻa ʻole o ka hohonu i nā kikoʻī ʻenehana, hōʻike ka hōʻike HDR i ka nui o ka luminance a me ka hohonu kala ma mua o nā pale i kūkulu ʻia e hoʻokō i nā kūlana kahiko.
MPRT 1ms no ka hōʻemi hou ʻana i ka neʻe ʻana
1MSManawa panee hōʻemi ana i ka ghosting & blurring i ka wā e hoʻololi ana i nā pika, mālama mau i ka ʻenemi a me ka ʻāina i ka nānā pono ʻana i nā manawa haunaele.
10 Bit waihoʻoluʻu pukahiki ke hōʻike ma waena o 0000000000 a hiki i 1111111111 i kēlā me kēia o nā kala ʻulaʻula, uliuli, a melemele, ʻo ia hoʻi, hiki i kekahi ke hōʻike i 64x o nā kala o 8-bit.Hiki i kēia ke hana hou i ka 1024x1024x1024 = 1,073,741,824 kala, ʻo ia ka nui o nā kala ma mua o 8 bit.No kēia kumu, ʻoi aku ka maʻalahi o ka nui o nā gradients o ke kiʻi e like me ke kiʻi ma luna, a ʻoi aku ka maikaʻi o nā kiʻi 10 bit ma mua o ko lākou mau hoa 8-bit.
