2. Advanced Peev Xwm:
DisplayPort 1.2: Txhawb 4K daws teeb meem ntawm 60Hz thiab 1440p ntawm 144Hz.
DisplayPort 1.3: Ntxiv kev txhawb nqa rau 8K daws teeb meem ntawm 30Hz.
DisplayPort 1.4: Ntxiv kev txhawb nqa rau 8K ntawm 60Hz nrog HDR thiab 4K ntawm 120Hz.
DisplayPort 2.0: Ua kom muaj peev xwm ua tau zoo, txhawb nqa txog 10K daws teeb meem ntawm 60Hz thiab ntau yam 4K zaub ib txhij.
3. Kev thauj mus los ntau yam (MST):
Qhov zoo tshaj plaws ntawm DisplayPort yog MST, uas tso cai rau ntau qhov kev sib txuas los ntawm ib qho chaw nres nkoj. Qhov kev muaj peev xwm no tshwj xeeb yog qhov zoo rau cov neeg siv xav tau kev nthuav dav ntau qhov kev teeb tsa.
4. Adaptive Sync Technologies:
DisplayPort txhawb nqa AMD FreeSync thiab NVIDIA G-Sync, thev naus laus zis tsim los txo cov kev tshuaj ntsuam tearing thiab stuttering hauv kev ua si, muab kev pom kev zoo dua.
HDMI thiab DisplayPort hauv LED Zaub
1. Clarity thiab Brightness:
Ob qho HDMI thiab DisplayPort yog qhov tseem ceeb hauv kev xa cov yeeb yaj kiab siab txhais tau tias cov lus qhia LED paub txog. Lawv xyuas kom meej tias cov ntsiab lus raug xa mus yam tsis muaj kev poob zoo, tswj xyuas qhov ntse thiab ci ntsa iab uas LED thev naus laus zis muab.
2. Xim raug thiab HDR:
Cov qauv niaj hnub ntawm HDMI thiab DisplayPort txhawb nqa High Dynamic Range (HDR), txhim kho cov xim ntau thiab qhov sib piv ntawm cov zis video. Qhov no yog qhov tseem ceeb rau LED zaub, uas tuaj yeem siv HDR kom xa cov duab zoo nkauj dua thiab zoo li lub neej.
3. Cov Nqi Kho Dua Tshiab thiab Kev Ua Haujlwm Zoo:
Rau cov ntawv thov uas xav tau tus nqi refresh siab, xws li kev ua si lossis kev ua yeeb yaj kiab kho, DisplayPort feem ntau yog qhov kev xaiv zoo dua vim nws qhov kev txhawb nqa rau cov qib siab dua ntawm kev daws teeb meem siab. Qhov no ua kom lub zog du thiab txo qhov plooj hauv qhov nrawm nrawm.
4. Kev sib xyaw thiab kev teeb tsa:
Kev xaiv ntawm HDMI thiab DisplayPort kuj tuaj yeem cuam tshuam los ntawm cov kev xav tau ntawm kev teeb tsa. HDMI's CEC thiab kev sib raug zoo dav ua rau nws yooj yim rau cov neeg siv khoom teeb tsa, thaum DisplayPort's MST thiab kev ua haujlwm siab yog qhov zoo hauv ntau qhov chaw ua haujlwm.
Xaiv qhov zoo interface
Thaum xaiv ntawm HDMI thiab DisplayPort rau koj qhov teeb tsa LED, xav txog cov hauv qab no:
1. Ntaus Compatibility:
Xyuas kom meej tias koj li pab txhawb lub interface xaiv. HDMI muaj ntau dua nyob rau hauv cov neeg siv khoom siv hluav taws xob, thaum DisplayPort muaj ntau nyob rau hauv cov qib kev saib xyuas thiab cov duab phaib.
2. Resolution thiab Refresh Rate Xav Tau:
Rau kev siv dav dav, HDMI 2.0 lossis siab dua yog feem ntau txaus. Rau cov ntawv thov, xws li kev ua si lossis kev tshaj tawm kev tshaj tawm, DisplayPort 1.4 lossis 2.0 yuav tsim nyog dua.
3. Cable Length thiab teeb liab zoo:
DisplayPort cables feem ntau tswj cov teeb liab zoo nyob ntev dua zoo dua li HDMI cables. Qhov no yog ib qho tseem ceeb rau kev txiav txim siab yog tias koj xav tau txuas cov khoom siv los ntawm qhov deb tseem ceeb.
