Ka taea e te HDMI 2.0 te mahi i te 4K 120Hz? Te Pono i Muri i te Pāngarau Whānui
1. Ngā Herenga Mārō o te HDMI 2.0: He aha i Rahua ai te 4K/120Hz
HDMI 2.0 Te herenga whānui 18Gbps ko tōna rekereke o Ākirīhi. Me wehewehe ngā tau:
-
4K/60Hz = 12.54Gbps (Kua kōpeketia ki te chroma 4:2:0)
-
4K/120Hz = 25.08Gbps (Ahakoa te kōpeketanga 4:2:0)
Te whakataunga:
✅ HDMI 2.0 kēne kakau 4K/60Hz, 1440p/120Hz rānei
❌ E 39% te nui ake o te whānui o te 4K/120Hz i tōna whānui – te take o ngā mata mangu, te hanga taonga rānei.
Whakamātautau o te ao tūturuTe hono i tētahi RTX 4080 ki te LG C2 OLED mā Taura HDMI 2.0:
-
Putanga kua whakatakotoria ki te 4K/120Hz → "Tohu kei waho o te awhe" hapa
-
Kua whakahekehia ki te 4K/60Hz → whakaaturanga pumau.
2. Te Tinihanga "120Hz Rūpahu": Te Māngai a ngā Kaihoko
Kia tūpato ki ngā taura e hokohokohia ana pēnei:
"E tautoko ana a HDMI 2.0 i te 4K 120Hz!"
Te tinihanga a rātou:
-
Te whakamahi te tauira iti o te kōroma (4:2:0) ki i roto i te ariā whakaurua te 4K/120Hz ki roto i te 18Gbps
-
Te ao tūturuTe nuinga o ngā mata tirotiro/pouaka whakaata kaua e whakaaetia te 4:2:0 i te 120Hz – te whakahoki i te tere ki te 60Hz.
Ngā raraunga taiwhanga:
| Tautuhinga | Te Pūmautanga o te HDMI 2.0 |
|---|---|
| 4K/120Hz 4:4:4 | ❌ Kāore i angitu |
| 4K/120Hz 4:2:0 | ⚠️ 27% o ngā taputapu e mahi ana |
| 4K/60Hz 4:4:4 | ✅ Pūmau |
3. Te Otinga: Kua Whaimanahia HDMI 2.1 mō te 4K/120Hz Pono
Hei wetewete i te 4K/120Hz tūturu, me:
-
Te whānui o te HDMI 2.1 he 48Gbps
-
Tiwhikete HDMI Tere Tino Teitei (Ka taea te manatoko i te waehere QR)
-
Te Kōpeketanga Rere Whakaatu (DSC) 1.2 tautoko (kōpeketanga kore-ngaro)
He aha i whakamanahia ai e ā mātou taura te mahi:
-
Ngā matua parahi kore-hāora 24AWG → te ngaronga tohu iti rawa
-
Parenga EMI paparanga-toru → kore pokanoa mai i ngā pouara/waea
-
Whakamātauria-rōpū i te 48Gbps (mā ngā CTA o te Huinga Kōrero HDMI)

PS5/Xbox Raupapa XMe HDMI 2.1 ngā tauranga + ngā taura mō te 4K/120Hz
-
Ngā GPU NVIDIA RTX 30/40Whakamahinga DisplayPort 1.4a mēnā kāore e wātea ana te HDMI 2.1.
Ngā Whakaaro Matua mō ngā Kaiwhakamahi
-
HDMI 2.0 ≠ 4K/120HzKo te whānui o te hononga ka herea ki te 18Gbps (4K/60Hz te mōrahi).
-
Kei reira ngā tinihanga hokohokoKa whakamahia e ngā tapanga "4K 120Hz" i runga i ngā taura HDMI 2.0 ngā arai hangarau.
-
He mea nui te tiwhiketeAnake HDMI Tere Tino Tere Ka whakarite ngā taura i te tukunga o te 48Gbps.
-
Kia tupato ki te tiaki i te heke mai: Taura HDMI 2.1he hototahi ki ngā taputapu tawhito.
