3. VRR (Tus Nqi Hloov Kho Tshiab): Tshem Tawm Kev Tearing Screen
VRR tso cai rau lub TV hloov kho nws qhov refresh rate kom phim qhov frame rate uas lub console/PC tsim. Qhov no tiv thaiv kev tawg ntawm qhov screen (ib daim duab "rhuav" uas tshwm sim los ntawm cov frames tsis sib xws). Hauv kev tsim khoom TV ua si, kev txhawb nqa VRR feem ntau cuam tshuam nrog cov qauv hauv qab no:
- HDMI VRR (ib feem ntawm HDMI 2.1),
- AMD FreeSync,
- NVIDIA G-SYNC Sib xws rau qee cov qauv.
Kev siv VRR yuav tsum tau ua kom sib haum xeeb ntawm HDMI input, image processor, thiab panel. Qhov teeb meem ntawm kev siv tshuab yog tswj qhov kaj kom ruaj khov thiab zam kev flicker ntawm cov frame rates qis.
4. ALLM thiab Hom Kev Ua Si: Txo Qhov Lag Luam Nkag
Ib qho ntawm cov kev tsis txaus siab loj tshaj plaws txog kev ua si hauv TV ib txwm yog qhov qeeb ntawm kev nkag mus - qhov qeeb ntawm kev nias lub pob thiab qhov kev nqis tes ua tshwm sim ntawm qhov screen. Txhawm rau daws qhov teeb meem no, cov TV ua si muaj Game Mode uas kaw qhov kev ua cov duab hnyav (xws li kev txo suab nrov lossis kev txav mus los) kom ua kom lub sijhawm ua tiav sai dua.
Tsis tas li ntawd xwb, muaj qhov ALLM (Auto Low Latency Mode), uas yuav qhib hom low-latency thaum lub TV pom lub console lossis gaming signal. Los ntawm kev tsim qauv system, ALLM xav tau firmware uas tuaj yeem paub txog cov metadata ntawm lub teeb liab thiab hloov cov duab ua haujlwm yam tsis cuam tshuam kev sib txuas.
5. HDMI 2.1: Txoj Kev Tseem Ceeb rau 4K 120 fps
Yog xav kom 4K du ntawm 120 fps, yuav tsum muaj bandwidth loj. Qhov no yog qhov uas HDMI 2.1 los rau hauv, vim nws txhawb nqa cov yam ntxwv xws li:
- 4K @ 120Hz,
– VRR,
– ALLM,
– eARC (rau lub suab siab daws teeb meem).
Thaum lub sijhawm tsim khoom, cov chaw tsim khoom yuav tsum xaiv cov HDMI chipset uas tsim nyog, xyuas kom meej tias lub voj voog PCB ua tau raws li cov qauv teeb liab siab, thiab ua qhov kev sim sib xws nrog ntau yam khoom siv (PlayStation, Xbox, PC GPUs). Qhov zoo ntawm kev siv HDMI feem ntau ua rau muaj qhov sib txawv: qee lub TV thov tias muaj HDMI 2.1, tab sis tsuas yog ntawm cov chaw nres nkoj tshwj xeeb lossis muaj kev txwv.
6. Kev Ua Duab: Nruab Nrab Cov Duab Zoo Nkauj thiab Kev Teb Sai
Cov TV niaj hnub nim no muaj cov processors duab muaj zog, feem ntau muag hauv cov npe tshwj xeeb. Cov processors no ua haujlwm:
- Kev nce qib (piv txwv li ntawm 1080p mus rau 4K),
- HDR lub suab kos duab,
- Txo suab nrov,
- Kev ua kom du ntawm kev txav mus los.
Rau kev ua si, cov chaw tsim khoom yuav tsum sib npaug qhov zoo thiab latency. Qee lub TV muab HGIG (HDR Gaming Interest Group), ib txoj hauv kev uas tshem tawm qhov kev teeb tsa suab ntau dhau thiab tso HDR calibration rau lub console / game. Qhov no pab HDR cov zaub zoo li sib xws dua thiab txo qhov kev pheej hmoo ntawm cov ntsiab lus tseem ceeb raug txiav tawm.
7. HDR thiab Kev Tswj Xyuas Qhov Ci: Cov Lus Qhia Txog Thaj Chaw Tsaus Ntuj thiab Thaj Chaw Ci
Cov kev ua si niaj hnub nim no vam khom HDR ntau heev los ua kom lub ntiaj teb zoo li tiag tiag. Cov thev naus laus zis cuam tshuam nrog kev ua si TV suav nrog:
- Qhov ci ntsa iab tshaj plaws (qhov ci ntsa iab tshaj plaws),
- Kev tsaus ntuj hauv zos ntawm mini-LED,
- OLED pixel-level dimming,
- Kev txhawb nqa rau HDR hom ntawv xws li HDR10, HDR10 +, Dolby Vision (qee lub TV kuj txhawb nqa Dolby Vision rau kev ua si ntawm qee lub platform).
Nyob rau sab tsim khoom, qhov chaw teeb tsa dimming hauv zos yog qhov tseem ceeb heev. Yog tias lawv nruj dhau, paj (lub teeb ci) tuaj yeem tshwm sim lossis cov ntsiab lus tsaus ntuj tuaj yeem ploj mus. Yog tias lawv tsis muaj zog dhau, qhov sib piv yuav tsis zoo.
8. Lub Sijhawm Teb Pixel thiab Blur
Ntxiv rau qhov qeeb ntawm kev nkag, muaj lub sijhawm teb pixel: cov pixels hloov pauv sai npaum li cas los ntawm ib xim mus rau lwm xim. Lub sijhawm teb qeeb ua rau muaj kev tsaus ntuj lossis qhov tsis meej. OLEDs feem ntau ua tau zoo ntawm no, thaum LCDs xav tau cov txheej txheem zoo li overdrive (kev hloov pauv amplification) kom ua tiav cov txiaj ntsig sai dua. Txawm li cas los xij, overdrive ntau dhau tuaj yeem ua rau overshoot (cov duab tig rov qab). Yog li ntawd, cov chaw teeb tsa Hoobkas thiab firmware yog qhov tseem ceeb rau kev ua tau zoo tiag tiag.
9. Lub Tshuab Ua Haujlwm, Firmware, thiab Cov Nta Ntxiv ntawm Kev Ua Si
Cov TV ua si niaj hnub no tsis yog hais txog kho vajtse xwb, lawv kuj hais txog software. Ntau tus qauv muaj:
