Ko HDMI 2.0 inogona here kuita 4K 120Hz? Chokwadi chiri shure kweBandwidth Math

1. HDMI 2.0's Hard Limits: Nei 4K/120Hz Isingashande

HDMI 2.0's 18Gbps bandwidth cap ndiyo chitsitsinho chayo cheAchilles. Ngationgororei nhamba dzacho:

• 4K/60Hz = 12.54Gbps (Yakamanikidzwa ne 4:2:0 chroma)

• 4K/120Hz = 25.08Gbps (Kunyangwe nekumanikidzwa kwe4:2:0)

Mutongo:
✅ HDMI 2.0 kani mubato 4K/60Hz kana 1440p/120Hz
❌ 4K/120Hz inodarika bandwidth yayo ne39% - zvichikonzera matema kana kuti zvinhu zvakagadzirwa.

Bvunzo chaiyo: Kubatanidza RTX 4080 kuLG C2 OLED kuburikidza Waya yeHDMI 2.0:

• Kubuda kwakaiswa pa4K/120Hz → "Chiratidzo Chava Kunze Kwenzvimbo" chikanganiso

• Yaderedzwa kusvika pa4K/60Hz → kuratidzwa kwakagadzikana.

2. Hutsotsi hwe "Fake 120Hz": Mashandisirwo Anoitwa Vatengesi

Chenjererai tambo dzinotengeswa se:

"HDMI 2.0 inotsigira 4K 120Hz!"

Maitiro avanobiridzira:

• Kushandisa chroma subsampling (4:2:0) ku dzidziso isa 4K/120Hz mu18Gbps

• ChokwadiMaTV/ma monitor mazhinji musabvuma 4:2:0 pa120Hz - kumanikidza kudzokera kumashure kusvika ku60Hz.

3. Mhinduro: Yakatenderwa Hdmi 2.1 yeTrue 4K/120Hz

Kuti uvhure 4K/120Hz chaiyo, unoda:

• HDMI 2.1's 48Gbps bandwidth

• Chitupa cheUltra High Speed ​​​​HDMI (Inosimbiswa neQR code)

• Kudzvanywa kweDisplay Stream (DSC) 1.2 rutsigiro (kudzvanywa pasina kurasikirwa)

Nei tambo dzedu dzichivimbisa kushanda zvakanaka:

• 24AWG cores dzemhangura dzisina okisijeni → kurasikirwa kushoma kwechiratidzo

• Kudzivirira kweEMI kwezvikamu zvitatu → hapana kukanganiswa kubva kuma routers/mafoni

• Yakaedzwa neBatch pa48Gbps (kuburikidza neHDMI Forum CTAs)

👉 Zano reNyanzvi: Tarisa HDMI port version yemudziyo wako!

• PS5/Xbox Series X: Inoda HDMI 2.1 maports + tambo ye4K/120Hz

• NVIDIA RTX 30/40 GPUsShandisa DisplayPort 1.4a kana HDMI 2.1 isipo.

  

  Pfungwa Huru dzeVashandisi

  1. HDMI 2.0 ≠ 4K/120Hz: Zvivharo zvebandwidth pa18Gbps (4K/60Hz yakanyanya kukwira).

  2. Hutsotsi hwekushambadzira huripo: Mazita e "4K 120Hz" ari patambo dzeHDMI 2.0 anoshandisa nzira dzehunyanzvi dzekuvhura maburi.

  3. Chitupa chakakosha: Chete HDMI Yekumhanya Kwakanyanya Tambo dzinoita kuti 48Gbps isvike.

  4. Kuchenjerera mune ramangwana: Waya yeHDMI 2.1s inoshanda kumashure-inoenderana nemidziyo yekare.
