Kodi HDMI 2.0 Ikhoza Kuchita 4K 120Hz? Chowonadi Cha Masamu a Bandwidth

1. Malire Ovuta a HDMI 2.0: Chifukwa Chake 4K/120Hz Imalephera

Ma HDMI 2.0 Chikhomo cha bandwidth cha 18Gbps ndi chidendene chake cha Achilles. Tiyeni tigawane manambala:

• 4K/60Hz = 12.54Gbps (Yodzazidwa ndi chroma ya 4:2:0)

• 4K/120Hz = 25.08Gbps (Ngakhale ndi kupsinjika kwa 4:2:0)

Chigamulocho:
✅ HDMI 2.0 chitsulo chogwirira 4K/60Hz kapena 1440p/120Hz
❌ 4K/120Hz yapitirira bandwidth yake ndi 39% - kuyambitsa zowonetsera zakuda kapena zinthu zopangidwa.

Mayeso enieniKulumikiza RTX 4080 ku LG C2 OLED kudzera pa Chingwe cha HDMI 2.0:

• Zotulutsa zakhazikitsidwa ku 4K/120Hz → "Chizindikiro Chachoka Pamalo Osayandikira" cholakwika

• Yatsitsidwa kufika pa 4K/60Hz → chiwonetsero chokhazikika.

2. Chinyengo cha "120Hz Yabodza": Momwe Ogulitsa Amasokeretsera

Chenjerani ndi mawaya omwe amagulitsidwa ngati:

"HDMI 2.0 imathandizira 4K 120Hz!"

Momwe amachitira chinyengo:

• Kugwiritsa ntchito kusampulu kwa chroma (4:2:0) ku mwachiphunzitso ikani 4K/120Hz mu 18Gbps

• ZenizeniMa TV ambiri musavomereze 4:2:0 pa 120Hz - kukakamiza kubwerera ku 60Hz.

Deta ya labu:

3. Yankho: Yovomerezeka Hdmi 2.1 ya True 4K/120Hz

Kuti mutsegule 4K/120Hz yeniyeni, muyenera:

• Bandwidth ya HDMI 2.1 ya 48Gbps

• Satifiketi ya Ultra High Speed ​​​​HDMI (Kodi ya QR ingatsimikizidwe)

• Kukanikiza kwa Kuwonetsa Ma Stream (DSC) 1.2 chithandizo (kupondereza kosataya)

Chifukwa chake zingwe zathu zimatitsimikizira kuti zikugwira ntchito bwino:

• Mitsempha yamkuwa yopanda mpweya ya 24AWG → kutayika kochepa kwa chizindikiro

• Chitetezo cha EMI cha magawo atatu → palibe kusokoneza kwa ma rauta/mafoni

• Kuyesedwa kwa gulu pa 48Gbps (kudzera pa HDMI Forum CTAs)

👉 Malangizo a Akatswiri: Yang'anani mtundu wa doko la HDMI la chipangizo chanu!

• PS5/Xbox Series X: Imafuna HDMI 2.1 madoko + zingwe ya 4K/120Hz

• Ma GPU a NVIDIA RTX 30/40Gwiritsani ntchito DisplayPort 1.4a ngati HDMI 2.1 sikupezeka.

  

  Mfundo Zofunika Kwambiri kwa Ogwiritsa Ntchito

  1. HDMI 2.0 ≠ 4K/120Hz: Ma bandwidth caps pa 18Gbps (4K/60Hz max).

  2. Pali chinyengo cha malonda: Zolemba za “4K 120Hz” pa zingwe za HDMI 2.0 zimagwiritsa ntchito njira zaukadaulo zochotsera zingwe.

  3. Chitsimikizo n'chofunika kwambiri: Kokha HDMI Yothamanga Kwambiri zingwe zimathandizira kuti 48Gbps ifike.

  4. Kutsimikizira zamtsogolo mwanzeru: Chingwe cha HDMI 2.1imagwira ntchito mobwerera m'mbuyo ndi zipangizo zakale.
