Yog tias koj tau siv sijhawm txhua lub sijhawm ntawm cov rooj sib tham hauv tsev, koj tau zaum dhau los ntawm cov ntaub ntawv tsis raug txaus kom tsim nyog rau kev tshem tawm digital. Txhua tus tau txais kev xav-feem ntau xa nrog kev ntseeg siab ntawm TED Talk thiab qhov tseeb ntawm koj tus txiv ntxawm piav qhia 5G hauv Facebook. Koj pib nrhiav cov lus teb yooj yim txog kev teeb pom kev tsis ncaj ncees thiab xaus kev xav tej zaum immersion yog Latin rau qhov muag. Txoj xov zoo? Nyob ntawd yog cov qauv-thiab peb tag nrho vim li cas rau cov uas twb muaj lawm raws li ib lub tuam txhab yog ua raws li lawv.

Qhov xwm zoo yog, qhov no tsis yog nab roj. Thiab cia peb ua ntej - muaj ntau ntawm nab roj tawm muaj. Lub teeb pom kev tsis zoo tsis zoo li cov $ 200 kub HDMI cables uas tau cog lus tias yuav txhim kho cov duab tab sis xa tsis muaj dab tsi. Qhov no yog tsim kev tshawb fawb, tsis yog fad lossis "hack." Nws yog tus qauv duab thoob ntiaj teb siv txhua qhov chaw los ntawm cov xim-qib suites mus rau kev kho mob-tso duab engineering labs.

Thiab lwm yam xov xwm zoo? Qee tus neeg ntawm cov rooj sab laj no mob siab txog kev ua kom raug. Tus so... zoo, cia peb hais tias kev txaus siab tsis yog tib yam li kev txawj ntse. Yog li ua ntej peb mus ntxiv, ua pa tob tob. Koj nyob nyab xeeb ntawm no. Tsis muaj kev sib txuas, tsis muaj flashing RGB, tsis muaj "cinematic ambiance" nab roj. Tsuas yog qhov tseeb nrog me ntsis teeb pom kev zoo. 

Tswvyim #1: Lub teeb pom kev tsis zoo yog cuam tshuam.

Yog tias nws cuam tshuam, ib yam dab tsi tsis ncaj ncees lawm. Lub teeb pom kev ncaj ncees zoo yog hloov maj mam thiab ruaj khov. Nws ua tau txo kev cuam tshuam los ntawm kev muab koj ob lub qhov muag qhov nruab nrab siv taw tes thiab pab lawv so kom txaus thaum lub teeb ci hloov. Lub hom phiaj yog ua kom cov duab zoo dua qub, tsis yog ua kom cov phab ntsa ci ntsa iab zoo li ib hmo ntuj. 

Tswvyim #2: Cov xim phab ntsa ua rau lub teeb pom kev tsis zoo.

Qhov no yog ib qho misconception. Cov xim ntawm koj phab ntsa cuam tshuam rau lub teeb pom kev deb tsawg dua li cov neeg feem coob xav txog. Koj tsis calibrate ib qho zaub rau cov xim ntawm koj phab ntsa, thiab yog tias koj saib TV hauv chav teeb, koj twb pom phab ntsa - thiab nws tsis ua rau koj cov duab puas. Bias teeb pom kev zoo tsuas yog teeb pom kev zoo - teeb pom kev zoo nyob rau hauv qhov chaw, ntawm qhov kaj ci, thiab ntawm qhov chaw dawb. Nws tsis yog sim "sib ntaus" koj cov xim phab ntsa. Tseeb, nruab nrab grey yog qhov zoo tagnrho, tab sis cov khawv koob tiag tiag yog nyob rau hauv qhov chaw, siv, thiab xim raug, tsis yog koj cov phab ntsa yog "kev siv grey."

Tswvyim #3: OLEDs tsis xav tau teeb pom kev zoo.

Cov neeg hais tias "OLEDs muaj cov xim dub zoo meej, yog li koj tsis xav tau teeb pom kev tsis zoo." Tab sis qhov ntawd yog vim li cas koj ua. Qhov sib sib zog nqus tob dua, qhov ntau koj ob lub qhov muag tawm tsam kom hloov ntawm qhov kaj thiab tsaus ntuj. Bias teeb pom kev zoo stabilizes qhov kev hloov pauv yog li koj tuaj yeem pom qhov nthuav dav hauv ob qho tib si. Kuj tseem muaj qhov ua tau zoo heev los siv nws. OLEDs, rau tag nrho lawv lub zog, tsis yog lub teeb ci tshaj plaws nyob ib puag ncig, thiab lawv yooj yim rau cov duab me me thiab cov duab ntxoov ntxoo banding. Bias teeb pom kev zoo pab tswj ob qho tib si. Los ntawm kev txo qhov pom kev dhia ntawm qhov tsaus ntuj thiab ci ntsa iab, cov faint retention ghosts thiab subtle bands ua tsis tshua pom. Nws kuj ua rau cov duab zoo li ci ntsa iab tag nrho, yog li koj tuaj yeem yooj yim khiav cov zaub ntawm qib qis dua - uas ua rau nws ncua nws txoj sia. Cov neeg siv plasma paub qhov ua kom yuam kev no xyoo dhau los: kho lub qhov muag, tsis yog lub vaj huam sib luag. Ib zaug ntxiv, lub teeb pom kev tsis zoo tsuas yog qhov ci ntsa iab, qhov kub thiab txias, thiab qhov chaw zoo.

Tswvyim #4: Yog tias qhov teeb pom kev tsis zoo tsim nyog, cov yeeb yaj kiab yuav siv nws.

Nws yog ib qho uas pom qhov no parroted ntawm cov rooj sab laj, tab sis nws nkag siab yuam kev ua yeeb yam ua haujlwm li cas. Cov yeeb yaj kiab ua yeeb yaj kiab tsis yog tsaus ntuj - muaj lub teeb pom kev zoo txhua qhov. Koj tau txais lub teeb ci ntsa iab tawm ntawm qhov screen, lub teeb pom kev tsis pom kev, thiab ci ntsa iab tawm cov paib, txhua qhov muab cov txheej txheem hloov maj mam uas ua rau koj ob lub qhov muag tsis txhob poob rau hauv qhov tsaus ntuj tag nrho. Qhov ntawd tseem ceeb vim tias, hauv qhov tsaus ntuj tiag tiag, koj ob lub qhov muag tsim lawv tus kheej lub suab nrov hu ua Eigengrau - lub faint grey "mist" koj pom thaum tsis muaj teeb pom kev zoo.

Lub teeb pom kev tsis zoo ua haujlwm tib lub hom phiaj hauv kev teeb tsa hauv tsev: nws muab koj ob lub qhov muag qhov taw qhia ruaj khov, tiv thaiv qhov grey sab hauv kom koj tuaj yeem pom cov qib dub tiag tiag, tsis yog lub suab nrov koj lub hlwb invents. Thiab tsis zoo li kev ua yeeb yam, koj chav nyob marathon ntu ntev dua thiab koj lub vijtsam yog ze dua. Cov ntxaij vab tshaus ua yeeb yaj kiab tsis ci ntsa iab, thiab koj tsis zaum ob peb taw deb saib rau cov xuab moos thaum kawg. Lub teeb pom kev tsis zoo ua qhov tseem ceeb dua nyob rau hauv cov ntsiab lus ntawd - nws khaws qhov sib txawv, kev nplij siab, thiab kev pom meej nyob rau lub sijhawm.

Tswvyim #5: Cov xim hloov pauv yog ib yam zoo.
Yog tias qhov tseeb tseem ceeb, qhov no tsis yog. RGB strips yog tsim rau lub teeb pom kev zoo, tsis pom qhov nruab nrab. Koj xav tau ib qho, siab-CRI D65 dawb - tib tus qauv dawb siv los ua yeeb yaj kiab thiab TV. Cov xim hloov pauv yog kev lom zem rau kev ua si, tsis yog rau kev tsim cov duab ncaj ncees.

Tswvyim #6: Lub teeb sov sov yog qhov zoo dua rau koj ob lub qhov muag thiab pw tsaug zog.
Cov lus dab neeg no los ntawm kev ntshai ntawm lub teeb xiav. Ib feem uas txhua tus tawm mus yog kev siv zog. Lub teeb xiav tsuas yog ua rau pw tsaug zog cuam tshuam ntawm qib siab ci ntsa iab thiab thaum koj ntsia ncaj qha rau hauv qhov chaw. Cov teeb pom kev zoo tsis yog ib qho. Lawv tsis tshua dim, tsis ncaj, thiab tsis muaj flicker. Koj tsis saib rau hauv lawv, yog li lawv tsis ua rau koj lub circadian system. "Sov dawb kom tsaug zog zoo" suab zoo, tab sis nws tsis yog qhov tseeb.

Lus dab neeg #7: "Sov" TV teeb txhais tau tias koj xav tau kev teeb pom kev zoo dua qub.
Qhov no yog los ntawm ib qho yooj yim to taub. Thaum tib neeg pom daim duab hom sau npe Kub 2, lawv xav tias nws txhais tau hais tias qhov pom kev sov dua, ntau lub suab txiv kab ntxwv - yog li lawv xaiv lub teeb pom kev sib haum xeeb kom phim. Hauv kev muaj tiag, cov sov cov chaw twb tau calibrated rau D65, tib qhov nruab nrab dawb taw tes siv rau mastering ze li ntawm tag nrho cov video ntsiab lus. Bias teeb pom kev zoo tsis yog yuav tsum tau saib sov los yog txias; Nws yog meant kom phim qhov kev siv D65. Daim ntawv lo "sov" tsuas yog piav qhia txog kev kho me ntsis rau qhov raug, tsis yog hloov mus rau amber.

Tswvyim #8: Ci ntsa iab zoo dua.

Qhov no tsis kam tuag. Lub teeb pom kev ncaj ncees tsim nyog yuav tsum yog li 10% ntawm koj lub vijtsam qhov ci ci siab tshaj plaws - hloov maj mam, tsis pom lub teeb ci. Koj yuav tsum tsis txhob pom qhov kaj xaus thiab phab ntsa pib. Yog tias koj qhov teeb tsa zoo li tub ceev xwm nug qhov xwm txheej, koj tau mus dhau lawm. Kuv ib zaug muaj ib tug txiv leej tub ntawm Reddit sib cav tias qhov teeb pom kev tsis zoo yuav tsum yog tsawg kawg 4,000 lumens kom ua tau zoo - uas yog kwv yees li qhov tso zis ntawm lub tsheb loj kab teeb. Yog tias koj chav TV xav tau looj tsom iav dub, koj ua tsis yog lawm.

Tswvyim #9: Lub teeb pom kev tsis zoo tsuas yog rau cov kws tshaj lij xwb.

Nws tsis yog rau colorists lossis calibrators - nws yog rau txhua tus neeg uas xav kom lawv lub vijtsam saib zoo thiab lawv ob lub qhov muag tsis mob. Koj tsis tas yuav muaj tus saib xyuas waveform kom txaus siab rau qhov sib txawv thiab cov xim raug. Nws tsis yog elitist; nws yog qhov tseeb xwb.

Tswvyim #10: Lub teeb pom kev tsis zoo cuam tshuam rau kev ua haujlwm lossis ua rau poob.
Cas qhov no myth muaj nyob. Tej zaum vim pheej yig USB strips uas overload ports. Lub teeb pom kev ncaj ncees rub lub zog tsawg dua hmo ntuj. Nws tsis kov koj GPU lossis ua cov saw hlau. Nws tsuas yog lub teeb - tas li, tsis muaj flicker, thiab tag nrho sab nraum txoj kev teeb liab.

Tswvyim #11: Txhua qhov dawb LED sawb yuav ua.
Technically muaj tseeb, tib txoj kev instant kas fes yog technically kas fes. Feem ntau random LED strips tsis yog 6500K, muaj xim tsis zoo, thiab flicker phem nyob rau hauv PWM dimming. Lawv teeb pom kev, paub meej, tab sis lawv tsis ua raws li lub hom phiaj ntawm kev teeb pom kev tsis ncaj ncees: kev ruaj khov, raug siv. Yog tias qhov tseeb tsis muaj teeb meem, siv dab tsi. Yog tias ua tau, xaiv kom raug.

Tswvyim #12: Lub teeb pom kev tsis zoo yog rau kev zoo nkauj.

Nov yog Instagram ntxiab. Lub teeb pom kev tsis zoo tuaj yeem saib txias, tab sis qhov ntawd tsis yog lub hom phiaj. Nws lub hom phiaj yog txhawm rau txhim kho pom qhov sib txawv thiab txo qhov muag pom. Lub ci tsuas yog ib qho kev mob tshwm sim. Yog tias koj tab tom caum lub ci es tsis txhob cuam tshuam, koj tau plam qhov taw tes.

Tswv yim #13: Built-in bias teeb ntawm TVs yog zoo txaus.
Lawv feem ntau tsis yog. Integrated "ambient light" systems yog tuned rau kev ua yeeb yam, tsis raug. Lawv hloov xim, hloov qhov ci, thiab tsis tshua haum nrog D65. Nws yog qhov sib npaug ntawm lub Hoobkas pob ntseg - lawv technically ua haujlwm, tab sis koj tuaj yeem ua tau zoo dua.

Tswvyim #14: Kev tsis ncaj ncees teeb pom kev puas tsuaj HDR.
Cov neeg xav tias HDR yog hais txog qhov ci ntsa iab, yog li txhua lub teeb ntxiv yuav tsum rhuav tshem nws. Hauv kev muaj tiag, teeb pom kev tsis ncaj ncees pab HDR los ntawm kev ua kom koj ob lub qhov muag nyob rau hauv txoj cai hloov pauv. Yog tsis muaj nws, koj cov menyuam kawm ntawv yeej qhib thiab kaw ntawm qhov tseem ceeb thiab duab ntxoov ntxoo. Lub teeb pom kev ncaj ncees zoo tso cai rau koj pom tag nrho cov tonal tonal nthuav dav yam tsis muaj nkees.

Tswvyim #15: Teeb pom kev tsis zoo yog qhov nyuaj.
Nws tsis yog. Tsis muaj ib qho tshwj xeeb iav lossis calibration wizardry koom nrog. Nws tsuas yog hais txog lub teeb nyob rau hauv qhov chaw, ntawm qhov kaj ci, thiab ntawm qhov chaw dawb. Thaum koj teeb tsa nws, koj tsis tas yuav xav txog nws dua - tsuas yog xav paub seb koj puas tau saib yam tsis muaj nws.
