Ukwazi Oko Kujonga Xa Uthenga I-CRT Monitor ye-PC yakho
Ngenxa yobukhulu bayo kunye nefuthe lokusingqongileyo, iimboniso ezisekelwe kwi-CRT eziseleyo azivelwanga ngokusetyenziswa komsebenzisi jikelele. Ukuba ukhangele ukufumana isibonakaliso kwikhompyutheni yakho, khangela i- LCD ye-Monitor Buyer's Guide ebhekiselele kwiinkalo ezahlukeneyo kunye nobuchwephesha obusemva kweziboniso zekhompyutha ezikhoyo.
I-Cathode Ray Tube okanye abagadi be-CRT yindlela edala kunazo zonke yokubonakalisa iinkqubo zeekhompyutheni ze-PC. Iikhompyutri ezininzi zokuqala zibonise iziphumo zazo kumboniso wevidiyo oqhelekileyo oza kuboniswa kwiTV rhoqo. Njengoko ixesha liqhubekile, kunjalo nenqanaba lobugcisa beetyenziselwa ukubonisa iikhomputha.
Uluhlu loLondolozo kunye neNdawo eVulekayo
Bonke abahloli be-CRT bathengiswa ngokusekelwe kwisayizi yabo yeskrini. Oku kuluhlu lubhalwe ngokusekelwe kumlinganiselo wokudibanisa ukusuka kwikona engezantsi ukuya kwicala eliphambili lekrini kwisentimitha. Nangona kunjalo, ubungakanani bamehlo abuguquleli kwisayizi yokubonisa. Izibhengezo zethubhu ngokubanzi zikhutshwe ngephandle kwesikrini esingaphandle kwesikrini. Ukongezelela, ityhubhu ngokubanzi ayikwazi ukuvelisa umfanekiso kwimida ye-tube full size. Ngaloo ndlela, ufuna ngokwenene ukubheka ukulinganisa kwendawo ebonakalayo eyenziwa ngumenzi. Ngokuqhelekileyo indawo ebonakalayo okanye ebonakalayo yeso sihloli iya kuba malunga ne -9 ukuya kwe-1.2 intshi ezincinci kune-tube diagonal.
Isigqibo
Zonke izilindisi ze-CRT ngoku zibizwa ngokuba ngabagadi be-multisync. I-monitor iyakwazi ukulungelelanisa intambo ye-electron kangangokuthi iyakwazi ukubonisa izigqibo ezininzi kwiimeko ezihlaziyiweyo zokuhlaziya. Nalu uluhlu lwezinye izigqibo eziqhelekileyo ezisetyenziswa kunye kunye nesivakalisi sesisombululo:
- SVGA = 800x600
- XGA = 1024x768
- SXGA = 1280x1024
- UXGA = 1600x1200
Kukho iintlobo ezahlukeneyo zezigqibo ezikhoyo phakathi kwezi zigqibo eziqhelekileyo ezingasetyenziselwa ngongamela. Umyinge we-17 "I-CRT kufuneka ikwazi ukuyenza isisombululo se-SXGA kwaye ikwazi ukufikelela kwi-UXGA." Nayiphi na i-CRT okanye i-CRT enkulu kufuneka ikwazi ukwenza u-UXGA kwaye iphezulu.
Hlaziya iiRhafu
Izinga lokuhlaziya libhekisela kwinani lamaxesha apho umlindo unganqumla umgqomo phezu kwendawo epheleleyo yoboniso. Le nqanaba ingahluka ngokuxhomekeke kwisetyenziselwa ngumsebenzisi kwikhompyutheni yabo nokuba yiyiphi ikhadi levidiyo eliqhuba umboniso liyakwazi. Zonke ukuhlaziywa ngabahlaziyizicelo abavame ukuluhlu lwezinga eliphezulu lokuvuselela kwisisombululo esinikeziwe. Le nombolo ibhalwe kwiHertz (Hz) okanye iisondo ngeesibini. Ngokomzekelo, i-sheet yefowuni ingabhala into efana ne-1280x1024 @ 100Hz. Oku kuthetha ukuba iliso liyakwazi ukuskena iskrini ngamaxesha angama-100 ngesibini kwisisombululo se-1280x1024.
Ngoko kutheni umgangatho wokuhlaziya kwakhona? Ukubukela umboniso we-CRT ngexesha elide ixesha kunokubangela ukukhathala kwamehlo. Iindwendwe ezisebenza kwizinga eliphantsi lokuhlaziywa liza kubangela ukukhathala ngexesha elincinane. Ngokuqhelekileyo, kukulungele ukuzama ukufumana umboniso oza kubonisa kwi-75 Hz okanye engcono kwisisombululo esifunekayo. I-Hz engama-60 ithathwa njengona ubuncinci kwaye iyinqanaba lokuhlaziywa ngokuzenzekelayo lokuqhubela iividiyo kunye nabahloli kwiWindows.
Dot Pitch
Abakhiqizi abaninzi kunye nabathengisi abavame ukuluhlu lwee-dotch rate ratings. Olu phawu lubhekisela kubukhulu bepikelli enikeziweyo kwisikrini ngee-millimeters. Le nto yayiyinkathazo kwiminyaka edlulileyo njengoko izikrini ezama ukwenza izigqibo eziphezulu kunye nokulinganiswa kwamanqaku amakhulu kunomfanekiso ongezantsi ngenxa yombala ophumayo phakathi kweepikseli kwisikrini. Ukulinganiswa kwamanqaku angaphantsi okukhethiweyo kukhethwa njengoko kunika isibonakaliso esicacileyo somfanekiso. Uninzi lwezilinganiso zezi zinto ziya kuba phakathi kwe-.21 kunye no -28 mm kunye nezikrini ezininzi ezinokulinganisa okuphakathi malunga ne-25 mm.
Size iKhabinethi
Enye indawo abaninzi abathengi abaye bayayijonga xa kuthengwa iliso le-CRT ubuninzi bekhabhinethi. Izilwanyana ze-CRT zivame ukuba zininzi kakhulu kwaye zinzima kwaye ukuba unesithuba esilinganiselweyo sedesksi, mhlawumbi unganqamana nobukhulu beenyawo onokuthi ulungele kwindawo esinikeziwe. Oku kubaluleke ngokukodwa ukujongwa kwemeko. Uninzi lwezixhobo zekhompyutha kunye neeseksksi zivame ukuba neeshalafu ezihambelana neendlwana ezisekhompini. Iindwendwe ezinkulu kwiimeko ezinjalo zinokunyanzela ukubeka iliso ngokusondeleyo kumsebenzisi okanye ukukhawulela ukusetyenziswa kwebhobhodi.
Isiqulatho seSkrini
Iziboniso ze-CRT ngoku zinemibala eyahlukahlukeneyo phambi kwesikrini okanye ityhubhu. Iibhubhu zangaphambili ezifana neeseti zeTV zinomgangatho ojikelezayo ukwenzela ukuba kube lula kwifowuni ye-electron ukuskena ukubonelela umfanekiso ocacileyo. Njengoko iteknoloji yaqhubela phambili, izikrini ezifihliweyo zafika ezazingenawo umgca ngakwesobunxele nangakwesokudla kodwa indawo ephahleni. Ngoku abagadi be-CRT bafumaneke ngeeskrini ezicwangcisiweyo ngokubanzi kwimihlaba emibini engqamlekileyo neyiyo. Ngoko, uthini umbandela? Iimpawu eziphezulu zesikrini zibonisa ukukhanya okubangela ukukhanya kwesikrini. Njengamazinga aphantsi okuhlaziywa, iindleko ezinkulu kwikhompyutheni ikwandisa inani lokukhathala kwamehlo.
