Ingabe i-HDMI 2.0 ingakwazi ukwenza i-4K 120Hz? Iqiniso Ngezibalo Ze-Bandwidth

1. Imikhawulo Eqinile ye-HDMI 2.0: Kungani i-4K/120Hz Yehluleka

Ama-HDMI 2.0 I-bandwidth cap ye-18Gbps isithende sayo sika-Achilles. Ake sihlukanise izinombolo:

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

• 4K/120Hz = 25.08Gbps (Ngisho noma ngabe kukhona ukucindezelwa okungu-4:2:0)

Isinqumo:
✅ I-HDMI 2.0 ithini isibambo 4K/60Hz noma 1440p/120Hz
❌ I-4K/120Hz idlula umkhawulokudonsa wayo ngo-39% – okubangela izikrini ezimnyama noma izinto ezenziwe ngezinto.

Ukuhlolwa kwangempela: Ukuxhuma i-RTX 4080 ku-LG C2 OLED nge Ikhebula le-HDMI 2.0:

• Umphumela usethwe ku-4K/120Hz → “Isiginali Ingaphandle Kwebanga” iphutha

• Yehliselwe ku-4K/60Hz → isibonisi esizinzile.

2. Ubuqhophololo "Bamanga be-120Hz": Indlela Abadayisi Abadukisa Ngayo

Qaphela izintambo ezithengiswa kanje:

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

Indlela abakhohlisa ngayo:

• Ukusebenzisa ukusampula okuncane kwe-chroma (4:2:0) ku- ngokwemfundiso faka i-4K/120Hz ku-18Gbps

• IqinisoAma-monitha/ama-TV amaningi ungawamukeli u-4:2:0 ku-120Hz – ukuphoqa ukubuyela emuva ku-60Hz.

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

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

• I-bandwidth ye-HDMI 2.1 engu-48Gbps

• Isitifiketi se-Ultra High Speed ​​​​HDMI (Ikhodi ye-QR ingaqinisekiswa)

• Ukucindezelwa Kokusakaza Kokubonisa (i-DSC) 1.2 ukwesekwa (ukucindezelwa okungenakulahlekelwa)

Kungani izintambo zethu ziqinisekisa ukusebenza kahle:

• Ama-cores ethusi angenawo umoya-mpilo angu-24AWG → ukulahleka okuncane kwesiginali

• Ukuvikela i-EMI okunezingqimba ezintathu → akukho ukuphazamiseka okuvela kuma-router/amafoni

• Kuhlolwe nge-Batch ku-48Gbps (nge-HDMI Forum CTAs)

• Uchungechunge lwe-PS5/Xbox X: Idinga i-HDMI 2.1 amachweba + izintambo kwe-4K/120Hz

• Ama-GPU e-NVIDIA RTX 30/40: Sebenzisa I-DisplayPort 1.4a uma i-HDMI 2.1 ingatholakali.

  

  Izinto Ezibalulekile Kubasebenzisi

  1. I-HDMI 2.0 ≠ 4K/120Hz: Izivalo ze-bandwidth ku-18Gbps (ubuningi be-4K/60Hz).

  2. Kukhona ukukhwabanisa kokumaketha: Amalebula “e-4K 120Hz” kumakhebula e-HDMI 2.0 asebenzisa iziphazamiso zobuchwepheshe.

  3. Isitifiketi sibalulekile: Kuphela I-HDMI Yesivinini Esiphezulu Kakhulu izintambo ziqinisekisa ukudlula kwe-48Gbps.

  4. Ubufakazi besikhathi esizayo ngokuhlakanipha: Ikhebula le-HDMI 2.1s isebenza emuva-iyahambisana namadivayisi amadala.
