Chii chisikopo chekuvandudza purogiramu

Mumazuva eRCT vatariri uye terevhizheni (cathode ray tube), munhu wose aifanira kunge ane pfungwa yakawanda yechinhu icho chinodzosera tsvina yekona. Kana, zvechokwadi, zvaikosha kuti agare

Chiratidzo, kwete kuti uwane hutano uye kushamwaridzana nekushanda pakushanda pakombiyuta kana kutarisa zvirongwa zveTV. Tinogona kutaura kuti chiyero chekuvandudza chekona chacho chakanga chisina kufanana nehutano. Munguva yedu, mamiriro ezvinhu akachinja zvikuru. Mazano ekuratidza ruzivo rwemifananidzo yakasikwa, achishandisa maitiro akasiyana zvakasiyana-siyana kupfuura teknolojia yeRT. Kunyange zvazvo chipikicha cheLCD muTV uye vatariri hachina kukwana zvakakwana kuti vataure pamusoro pokusava nemhosva kwakakwana: zvinoitika pane zvakaratidzwa zvakaderera zvikuru, asi hazvina kupera zvachose.

Kuti upindure mubvunzo pamusoro pekuti nguva yakawanda yekona yezorodza inozorora yakaenzana nei, ndiyo nzira iri nyore kune vadzidzisi vekombiyuta vanotarisa. Muchiitiko chekushandisa shanduro yezvino yeWindows operating system, unofanirwa kuunza mapeji mune chero nzvimbo isina mahwanda pakombiyuta nekudhonza kurudyi kwemakona uye osarudza "Screen Resolution" mune urongwa hunooneka. Ipapo unoda kuramba uchienda kune "Advanced Options". Pano, nokuzarura tab "Chengeta", unogona kuona mutsara "Ongorora purogiramu yevhenekeri".

Mumaziso ano mazuva ano anobva pamakristuru emvura, 59 uye 60 hertz anowanzowanika - izvi ndezvenyaya yebhajeti; Mune mari inodhura iwe unogonawo kugadzira 75 ne100 Hz. ILCD screen refresh rate iyo ndiyo nhaka yeCRT era. Mumiririro emakristani emvura "neziso" hazvibviri kusiyanisa pakati pe 60 ne100 Hz. Chinhu chimwe chete chinokonzerwa neyiyi parameter ndechokuti kufamba kwakanyatsoshandiswa kweve mouse cursor uye mukana wekushandisa magirazi 3D (100 Hz inodiwa kwavari).

Asi munguva ye CRT yakanga yakasiyana. Iko mukati memucheka (tube) yakafukidzirwa nehupamhi hwenheyo inokosha (phosphor), inokwanisa kupenya millisecond mashomanana mushure mokunge ma electrons akarova iyo. Zvitatu zvemagetsi (pfuti) yakabudisa mazaisai emiromo mihombe, iyo yakagadziriswa nemagnetic field. Yakanatsa marara kubva kumutsara wakarurama kuitira kuti kona yepamusoro-kuruboshwe yehwindo ichatanga kuzaruka kutanga, ipapo kuyerera kunokonzera kupenya pamuganhu wakananga kusvika

Kurudyi kumusoro kwekona. Zvadaro danda rakashandurwa rimwe rwonzi pasi uye zvose zvakadzokororwa. Paakazosvika kumucheto wekona wekona, akadzokera pakutanga uye zvose zvakadzokororwa. Nhamba yezvikwereti zvakadaro pamusi wechipiri ndiyo inongorodzwa.

MuLCD murairidzi anogona kukwanisa kushandura rutivi rwechiedza kuburikidza nezvinhu zvematrix emakristuru emvura - iwe unogona kuisa pamwe kana kuvhara kana kuvhara. Kuvhiringidzika kwechiedza chairo pachavo ndicho chakakosha chokupedzisira chiri kubviswa zvachose mumitambo mitsva yekuongorora. Iko phosphor pahwindo yakanga ichiri kuchenesa, ichigadzira kunyengera kwemufananidzo wakakwana. Ziso rakange risina nguva yekucherechedza kubhururuka kunokonzerwa nekuvandudzwa nguva dzose kwemufananidzo. Kunyange zvakadaro, yakanga iripo, uye pakuvandudza mitengo isingasviki 75 Hz yakange yakasimbiswa. Kuti abvise izvi, vakugadziri vanopa machengeti nemaferensi kunyange kupfuura 120 Hz. Zvechokwadi, iyo yakatsanangurwa chirongwa inonyoresa kunzwisisa - hatifungi kugadzirwa kwemuvara uye mufananidzo wacho pachako.
