Shin HDMI 2.0 Zai Iya Yin 4K 120Hz? Gaskiyar da ke Bayan Lissafin Bandwidth

1. Iyakoki Masu Wuya na HDMI 2.0: Dalilin da yasa 4K/120Hz ke Kasawa

HDMI 2.0 18Gbps iyakar bandwidth shine diddigin Achilles. Bari mu raba alkaluman:

• 4K/60Hz = 12.54Gbps (An matse shi da chroma 4:2:0)

• 4K/120Hz = 25.08Gbps (Ko da matsi 4:2:0)

Hukuncin:
✅ HDMI 2.0 gwangwani maƙalli 4K/60Hz ko 1440p/120Hz
❌ 4K/120Hz ya zarce bandwidth ɗinsa da kashi 39% - haifar da allo mai duhu ko kuma kayan tarihi.

Gwaji na GaskiyaHaɗa RTX 4080 zuwa LG C2 OLED ta hanyar Kebul na HDMI 2.0:

• An saita fitarwa zuwa 4K/120Hz → "Sigina Ta Fita Daga Wuri" kuskure

• An rage girman zuwa 4K/60Hz → nuni mai santsi.

2. Zamba ta "Karya 120Hz": Yadda Masu Sayarwa Ke Yaudara

Yi hankali da wayoyin da aka tallata kamar haka:

"HDMI 2.0 tana goyon bayan 4K 120Hz!"

Yadda suke yaudara:

• Amfani da samfurin chroma (4:2:0) zuwa a ka'ida Daidaita 4K/120Hz zuwa 18Gbps

• Gaskiya: Yawancin na'urorin saka idanu/TV kar a karɓi 4:2:0 a 120Hz - tilasta fallback zuwa 60Hz.

Bayanan dakin gwaje-gwaje:

3. Mafita: An Tabbatar HDMI 2.1 don Gaskiya 4K/120Hz

Don buɗe ainihin 4K/120Hz, kuna buƙatar:

• bandwidth na 48Gbps na HDMI 2.1

• Takaddun shaida na HDMI mai sauri sosai (Ana iya tantance lambar QR)

• Matsi na Nuni (DSC) 1.2 tallafi (matsi mara asara)

Me yasa kebul ɗinmu ke ba da garantin aiki:

• 24AWG cores na jan ƙarfe marasa iskar oxygen → ƙarancin asarar sigina

• Kariyar EMI mai matakai uku → babu tsangwama daga na'urorin sadarwa/wayoyi

• An gwada tsari a 48Gbps (ta hanyar HDMI Forum CTAs)

👉 Nasiha ga Ƙwararru: Duba sigar tashar HDMI ta na'urarka!

• PS5/Xbox Series X: Yana buƙatar HDMI 2.1 tashoshin jiragen ruwa + kebul don 4K/120Hz

• NVIDIA RTX 30/40 GPUs: Amfani Nunin Nuni 1.4a idan HDMI 2.1 bai samuwa ba.

  

  Muhimman Abubuwan Da Ya Kamata Masu Amfani Su Yi Amfani da Su

  1. HDMI 2.0 ≠ 4K/120Hz: Ƙarfin bandwidth a 18Gbps (mafi girman 4K/60Hz).

  2. Akwai zamba ta tallatawa: Lakabin "4K 120Hz" akan kebul na HDMI 2.0 suna amfani da ramukan fasaha.

  3. Takaddun shaida yana da mahimmanci: Kawai HDMI Mai Sauri Mai Tsayi kebul yana tabbatar da isar da wutar lantarki ta 48Gbps.

  4. Abin da zai tabbatar da nan gaba da hikima: Kebul na HDMI 2.1s yana aiki a baya-daidaita tare da tsofaffin na'urori.
