Kho kom tshiab tus nqi - uas yog ib qho zoo? Yuav ua li cas yog lub zaus ntawm qhov screen rau muab tso rau

Ntawm cov tseem ceeb kev yam ntxwv ntawm computer qhia thiab TV saib - tshiab tus nqi. Nyob rau hauv tej rooj plaub, qhov kev xaiv no yog tso cai? Thaum nws yog qhov kev kawm rau manually kho? Nyob rau hauv tej lub sijhawm, qhov no zoo ntawm txoj kev tsis tsim nyog?

Yuav ua li cas yog lub zaus ntawm lub screen?

computer saib los yog TV screen ua hauj lwm nyob rau hauv lub hauv paus ntsiab lus ntawm ib tug sib lawv liag ntawm ntas. Qhov ntawd yog ib yam dab tsi zoo li ib tug yeeb yam projector. Ncej nqi thaum me nyuam tus yeeb yam - txog 25-30. Nyob rau hauv cov ntaub ntawv ntawm ib tug PC saib los yog TV screen, qhov no qhia yuav tsum ntau dua, li ntawd, yuav ua li cas los tsim kom tau ib daim duab yog ntau npaum li cas nyuab tshaj qhov video on zaj duab xis. General txoj cai - lub siab tshwm sim nqi, sharper cov duab thiab qhov ntau qab ntxiag mus rau saib qhov screen.

Lub zaus thiab hom screen

Muaj ob peb hom hauj realization ntawm cov ntxaij vab tshaus thiab saib. Lub siab heev tshaj plaws - nws yog LCD, LCD thiab LED. Xam tias yog kuj qub CRT. Lub zaus update screen LCD TV los yog saib xyuas (nyob rau zoo xws li cov technology) li txiav txim siab xav lwm yam ntsiab cai tshaj nyob rau hauv cov ntaub ntawv nrog lub pab kiag li lawm nyob rau hauv uas lub electron nqaj txheej projections. Nyob rau hauv cov ntaub ntawv ntawm lub LCD duab yog twv rau tag nrho ntawm lub screen ib zaug.

Thaum nws los txog rau CRT-lus - kab. Yog li ntawd, yog hais tias tus refresh zaus yog lub LCD TV thiab ib tug electron nqaj tsev yog tib yam, qhov zoo tshaj uas muaj ntau yam yuav sib txawv mus rau tus thawj hom ntaus ntawv. Ntxiv mus, yog hais tias tus duab yog hais txog 60 Hz (tus naj npawb ntawm cov zaub ntas ib ob), ces nyob rau hauv cov ntaub ntawv ntawm lub CRT-saib yuav heev hnov li flicker.

zaus haum rau CRT-qhia

Yog li ntawd, peb them qhov chaw cathode txoj sab ci qhia tshwj xeeb mloog. Yuav ua li cas los mus hloov lub refresh tus nqi ntawm lub CRT-hom zaub nyob rau hauv lub qhov rais version ntawm cov piv txwv ntawm XP? Heev yooj yim. Teev nyob rau hauv "Control Vaj Huam Sib Luag". Ces xaiv "Screen." Qhib lub sib nug xov qhov rais, koj yuav tsum nrhiav tau cov tab "tej chaw". Tom ntej no - "Advanced". Muaj yog yuav tsum tau ib daim ntawv teev ob peb xaiv.

Yuav ua li cas yog lub refresh tus nqi teev? Rau CRT-saib pom zoo muaj nqis - 85 Hz. Yog hais tias qhov no daim duab yog tsis tau muaj npe, ces nws yog feem ntau tej zaum vim lub fact tias lub PC yog tsis teem rau lub Hoobkas video card tsav tsheb. Nws yuav tsum tau downloaded ntawm lub Internet los yog nrhiav drives uas txuas mus rau cov PC ua lag luam. Koj yuav tau sim hu rau cov kev pab cuam centre kev pab nrog tsav tsheb.

CRT-Qhia: nuances

Nco ntsoov tias nyob rau hauv yuav luag tag nrho cov kev khiav hauj lwm systems, nws tseem tau mus hloov no parameter, lub zaus ntawm lub screen refresh. Lub qhov rais 7 lub feem ntau niaj hnub thiab zoo li tsis muaj yuav tsum tseem ceeb pab nyob rau hauv qhov chaw ntawm tus neeg siv, tsis yog lub kos. Nyob rau hauv no version ntawm lub OS yuav tsum tau tsis nyob algorithm yog suab tib yam. Los ntawm lub "Control Vaj Huam Sib Luag" yog teem rau lub tseeb refresh tus nqi. Nws yog ib qhov zoo tshaj plaws operating system siv tau rau seeb tsim nyog nqis? Yuav luag tag nrho cov versions ntawm qhov rais mus rau tiv nrog neeg ua hauj lwm sib npaug. Txawm li cas los, kev xav txog cov feem ntau tsis ntev los no versions ntawm lub OS (tib yam lub qhov rais 7), tej zaum lawv yuav muaj tej teeb meem nrog tus tsav tsheb rau cov laus dua kiag li lawm. Tab sis lawv muaj peev xwm yuav daws tau - raws li ib tug txoj cai, tej kev tsim nyog hom software yuav muaj nyob hauv internet.

Tsis tas li ntawd, thaum ua hauj lwm nyob rau hauv lub qhov rais 7 tso tawm algorithm rau lub chaw yog ib nyuag txawv los ntawm tsab ntawv nyob rau hauv XP. Koj yuav tsum muaj nyob rau hauv lub "Control Vaj Huam Sib Luag," ces nias rau ntawm "zaub", ces - xaiv hloov nws tsis. Ces - "Advanced nqis". Tom ntej no, mus rau lub "Saib" tab, qhov uas peb nrhiav tau cov zaus chaw.

Nco ntsoov kuj - thaum seeb nyob rau hauv lub qhov rais tag nrho versions ntawm cov tsis yuav tsum tsis txhob tshem tawm ib tug zuam ze qhov khoom "Hide hom hais tias qhov no saib tsis siv." Qhov tseeb hais tias cov kev tshuaj ntsuam technology yog, ntawm chav kawm, muaj peev xwm mus ua hauj lwm nrog rau cov chaw yog pom zoo. Tab sis nyob rau hauv kev xyaum, nws yuav tsim ib tug teeb meem nrog cov PC stability. Yog li ntawd, yog hais tias tus neeg siv nug cov nqe lus nug, yuav ua li cas los mus hloov lub refresh tus nqi, yog hais tias tus tsim nyog kev xaiv no yog tsis muaj thiab tus nqi qis tshaj yog rau CRT-ntxaij vab tshaus, yog thawj zaug uas peb pom zoo kom nws - nruab qhov tseeb cov neeg tsav tsheb rau ib daim video.

kev daws teeb meem zoo tshaj

Nyob rau hauv tej rooj plaub, qhov zoo tshaj ntawm cov duab nyob rau hauv lub CRT-zaub nyob rau kev daws teeb meem. Thaum dua cov nqi rau qhov kev tshuaj ntsuam yog muab tso rau cia li ntau hais. Thiab nyob rau hauv cov ntaub ntawv ntawm, piv txwv li, nrog ib tug yees duab los yog yees duab, koj yuav saib tau lawv nyob rau hauv ntau yam. Pom kev daws teeb meem kev xaiv nyob ntawm seb feem nyob rau hauv tus nqi ntawm qhov kev tshuaj ntsuam nyob rau hauv nti. Tab sis, nyob rau hauv tus, tus neeg siv yuav xyaum ua tej yam nrog qhov chaw kawm txawv qhov tseem ceeb. Nco ntsoov tias lub rooj yuav raug hloov siv lub tib lub algorithm li thaum hloov lub zaus ntawm lub screen - nyob rau hauv "Control Vaj Huam Sib Luag" thiab "zaub."

Nco ntsoov kuj hais tias yog heev npaum li tso cai rau muab tso rau 85 Hz tsis yeej ib txwm ua hauj lwm. Thiab qhov no, incidentally, yog ib tug ntawm cov tau yog vim li cas vim li cas cov yam tooj tej zaum yuav tsis tshwm sim nyob rau hauv daim ntawv teev cov frequencies. Yog li ntawd, yog hais tias tus neeg tsav tsheb yog cov feem ntau tsis ntev los no, thiab 85 Hz tsis muaj npe, tej zaum koj yuav xav rau ib nyuag txo cov kev daws teeb meem ntawm lub monitor.

Zaus LCDs

Nws yuav tsum tau muab sau tseg, lub zaus ntawm muab kho dua rau cov duab hauv lub LCD screen - nyob rau hauv feem ntau qhov parameter uas twb tsis muaj ntsiab tshwj xeeb. Cias vim hais tias ntau los yog tsawg dua niaj hnub saib tseem nyob rau hauv lub Hoobkas teem kom cov zaus ntawm kev hloov yog tsuas yog tsis yuav tsum tau. Txawm yog hais tias nws yog sib npaug zos rau 60 Hz, uas yuav ua tau ib qho tseem ceeb rau CRT qhia, hnov flicker yog tsis vim lub hauj specifics uas peb tau hais los saum no. Txawm li cas los, kev xav txog cov LCD qhia, - rau lawv ntau ib qho tseem ceeb lwm yam parameter - cov hloov tshiab tus nqi ntawm pixels. Nyob rau hauv Feem ntau, nws, los ntawm txoj kev, yog nrhiav tau nrog cov "zaus" ntawm lub screen - txawm tias cov NWS-tshwj xeeb. Qhov no yog, nruj me ntsis hais lus, yog tsis heev muaj tseeb. Tsis kawg vim hais tias cov kev hloov tshiab tus nqi ntawm lub pixels yog tsis hais nyob rau hauv Hertz, thiab lwm cov ib - milliseconds. Tab sis, yog hais tias lub sij hawm siv nyob rau hauv lub ntsiab lus teb ntawm "zaus", tsis muaj ib tug, tej zaum tsis liam peb ntawm ib tug tsis muaj kev txawj ntse. Yog li ntawd, peb siv lub sij hawm "zaus" nyob rau hauv relation mus LCD qhia, peb to taub nws raws li ib tug "pixel refresh tus nqi."

Yog li ntawd, dab tsi yog qhov zoo tshaj plaws refresh tus nqi nyob rau hauv LCD saib? Qhov tseem ceeb tshaj - muab qhov zoo tshaj plaws phim rau no parameter cov ndlwg ntawm ntas generated los ntawm cov graphics card ntawm lub computer. Uas yog, yog tias, piv txwv li, lub nti yuav tso zis duab ntawm ib zaus ntawm 60 Hertz, thiab cov LCD yuav tsis muaj ib qho hloov tshiab tus nqi txaus pixels (xws taw qhia yuav suav hais tias kwv yees li 30-40 milliseconds), ces qhov kev tshuaj ntsuam duab yuav tshwm sim yuav tsum tau "floating" . Tsawg tshaj li cov coj parameter nyob rau hauv cov zaub, cov zoo. Qhov tseeb tiag mas, yog hais tias nws tsis pub tshaj 15 milliseconds. Raws li txoj cai, cov lus nug ntawm yuav ua li cas kom lub refresh tus nqi ntawm lub LCD hom, nws yog tsis tsim nyog. Nyob rau hauv lem, tus pixel refresh tus nqi - qhov chaw kawm nyob rau hauv feem ntau lub Hoobkas. Hloov nws nyob rau hauv tsev yog problematic. Yog li ntawd nws yog tsim nyog them sai sai rau nws ncaj qha thaum muas screen.
