Ngaba i-HDMI 2.0 ingenza i-4K 120Hz? Inyaniso engasemva kweBandwidth Math

1. Imida Enzima ye-HDMI 2.0: Kutheni i-4K/120Hz Ingaphumeleli

Ii-HDMI 2.0 I-bandwidth cap ye-18Gbps sisithende sayo sika-Achilles. Masiwahlule la manani:

• 4K/60Hz = 12.54Gbps (Icinezelwe nge-chroma eyi-4:2:0)

• 4K/120Hz = 25.08Gbps (Nokuba kukho ucinezelo lwe-4:2:0)

Isigwebo:
✅ I-HDMI 2.0 ikani phatha I-4K/60Hz okanye i-1440p/120Hz
❌ I-4K/120Hz idlula i-bandwidth yayo nge-39% – kubangela izikrini ezimnyama okanye izinto ezenziwe ngezinto.

Uvavanyo lwehlabathi lokwenyani: Ukudibanisa i-RTX 4080 kwi-LG C2 OLED nge Intambo ye-HDMI 2.0:

• Isiphumo simiselwe kwi-4K/120Hz → "Isignali Ayisekho Kuluhlu" impazamo

• Yehlisiwe ukuya kwi-4K/60Hz → isibonisi esizinzileyo.

2. Ubuqhetseba "be-120Hz bobuxoki": Indlela abaLahlekisa ngayo abathengisi

Lumka kwiintambo ezithengiswa ngolu hlobo:

"I-HDMI 2.0 ixhasa i-4K 120Hz!"

Indlela abakhohlisa ngayo:

• Ukusebenzisa ukuvavanya isampuli ye-chroma (4:2:0) ukuya ngokwethiyori faka i-4K/120Hz kwi-18Gbps

• InyaniUninzi lweemonitha/iiTV andiyamkeli i-4:2:0 kwi-120Hz – ukunyanzela ukubuyela umva kwi-60Hz.

3. Isisombululo: Siqinisekisiwe I-Hdmi 2.1 ye-True 4K/120Hz

Ukuze uvule i-4K/120Hz yokwenyani, udinga:

• I-bandwidth ye-48Gbps ye-HDMI 2.1

• Isatifikethi se-Ultra High Speed ​​​​HDMI (Ikhowudi yeQR iyaqinisekiswa)

• Uxinzelelo lweDisplay Stream (DSC) 1.2 inkxaso (uxinzelelo olungenalahleko)

Kutheni iintambo zethu ziqinisekisa ukusebenza kakuhle:

• Ii-cores zobhedu ezingenaoksijini ezingama-24AWG → ukulahleka okuncinci kwesignali

• Ukhuselo lwe-EMI oluneeleya ezintathu → akukho kuphazamiseka okuvela kwii-routers/iifowuni

• Ivavanywe yiBatch kwi-48Gbps (nge-HDMI Forum CTAs)

👉 Icebiso lobuGcisa: Jonga inguqulelo ye-HDMI port yesixhobo sakho!

• I-PS5/Xbox Series X: Ifuna i-HDMI 2.1 iiports + iintambo ye-4K/120Hz

• IiGPU zeNVIDIA RTX 30/40Sebenzisa I-DisplayPort 1.4a ukuba i-HDMI 2.1 ayifumaneki.

  

  Izinto ezibalulekileyo kubasebenzisi

  1. I-HDMI 2.0 ≠ 4K/120Hz: Iikhephu ze-bandwidth kwi-18Gbps (ubuninzi be-4K/60Hz).

  2. Kukho ubuqhetseba bokuthengisa: Iilebhile ze-“4K 120Hz” kwiintambo ze-HDMI 2.0 zisebenzisa iindlela zobugcisa zokuvula iingcango.

  3. Isiqinisekiso sibalulekile: Kuphela I-HDMI yesantya esiphezulu kakhulu iintambo ziqinisekisa ukudluliselwa kwe-48Gbps.

  4. Ubungqina bekamva ngobulumko: Intambo ye-HDMI 2.1Ukusebenza ngasemva kuhambelana nezixhobo ezindala.
