Ukulungiswa kwesikrini se-TV – uyini umehluko nokuthi ungakhetha kanjani kuzo zonke izinhlobo

Ukulungiswa kwe-TV – kuyini, yiziphi izinhlobo ezikhona nokuthi ungakhetha kanjani.

Kuyini, kungani kubalulekile ukukhetha ukulungiswa kwesikrini se-TV esifanele

Lapho bethenga i-TV, bavame ukuzama ukukhetha eyodwa enganikeza ikhwalithi ephezulu. Kodwa-ke, lapho ufunda izinketho ezitholakalayo, umsebenzisi ubhekene nokuba khona kwezinhlobonhlobo zemingcele yezobuchwepheshe, okungelula ngaso sonke isikhathi ukuyiqonda. Ukulungiswa kwesikrini kungenye yezinto ezibaluleke kakhulu lapho ukhetha imishini yethelevishini yekhwalithi ephezulu. Ukuze uqonde kangcono indima yayo ekuqinisekiseni ikhwalithi yesibonisi, udinga ukuqonda izimiso lapho ukusebenza kwesikrini kusekelwe khona. Kuyaziwa ukuthi ukuphakama kwesinqumo, isikrini sisebenzisa amaphikseli amaningi.

Amaphikseli ayizici, ngayinye ehlinzeka ngokuboniswa kwekhwalithi ephezulu kakhulu yephoyinti elithile, ndawonye kwakheka isithombe esishintshayo sokubonisa ividiyo.

Amaphikseli ahlelwe ngemigqa namakholomu. Lapho ucacisa imvume, inombolo yakho kokubili iyashiwo. Ukuba khona kwenani elikhulu lezakhi ezinjalo kwenza isithombe sibe nemininingwane eminingi kanye nekhwalithi ephezulu. Udinga futhi ukunaka ukuthi yiliphi inani nekhwalithi yemibala etholakalayo ngephikseli ngayinye. Le mingcele ayixhomeki kuphela ngobuningi, kodwa futhi nobuchwepheshe obusetshenzisiwe. Kubalulekile futhi ukuthi isithombe sikhanyiselwe kahle kangakanani. Kwezinye izikrini kunikezwa ngamaphikseli, kwezinye kunesendlalelo esikhethekile sale njongo.
Ukwakhiwa kwamaphikseli kuncike kubuchwepheshe obusetshenzisiwe. Ezimweni eziningi, aqukethe amaphikseli amathathu (okuluhlaza, okuluhlaza okwesibhakabhaka nokubomvu), okusethwe kuwo ukukhanya ngokuhlukana. Ikhwalithi yesithombe inqunywa kakhulu ngokulungiswa kwesikrini, kodwa futhi incike kwezinye izicaciso ze-TV nezimo zokubuka. Ngesikhathi esifanayo, isibonelo, banaka usayizi we-diagonal, i-aspect ratio yesikrini, ibanga phakathi kombukeli nesikrini, nabanye. https://cxcvb.com/texnika/televizor/vybor-podklyuchenie-i-nastrojka/na-kakoj-vysote-veshat-televizor.html Ukuminyana kwamaphikiseli kuyintshi yesikwele ngayinye kubalulekile. Isibonelo, ukusebenzisa ukulungiswa kwe-1920×1080 kuzohluka ngokubukeka kumamonitha angu-24″ kanye nama-27″ ngenxa yokuthi isici esishiwo sizohluka. Kufanele futhi unake izinga lokuvuselela isikrini. Uma iphansi kakhulu, isithombe sizocwayiza kancane, ngaleyo ndlela sibe nesandla ekwenyukeni okuphawulekayo kobunzima bamehlo.

Kukholelwa ukuthi imfuneko encane ingu-60 Hz, kodwa khumbula ukuthi ukuphakama kwemvamisa, isithombe sizoba ngcono.

Udinga futhi ukunaka uhlobo lokushanela olusetshenzisiwe. Izinhlobo ezimbili ezivame ukusetshenziswa:

• kuhlanganiswe;
• okuqhubekayo.

Esimweni sokuqala, ngisho nemigqa yamaphikseli ibuyekezwa kuqala, bese imigqa eyinqaba kamuva. Okunye ukucutshungulwa kwemigqa elinganayo neyinqaba kubangela ukucwayiza, okubangela ukukhathala kwamehlo. Ibuyekeza yonke imigqa eqhubekayo. Esimweni sesibili, ukubuyekezwa kwesikrini kwenziwa ngokushelela.

Ukulungiswa okuhle kuthinta izici ezilandelayo:

1. Inikeza imininingwane yesithombe . Ngokulungiswa okuphezulu, izibukeli zibona isithombe esicacile futhi zingabona kalula yonke into eziyithandayo.
2. Ukuhumusha kombala wemvelo kukuvumela ukuthi ubone kangcono okwenzekayo ngenkathi ubukele.
3. Ukukhanya nokujula kwesithombe kukhulisa imvelo yesithombe.
4. Ukungabi bikho koshintsho olubukhali phakathi kwamaphikseli kuyimfuneko yokubonisa ikhwalithi ephezulu.
5. Awekho amathoni noma amazwibela angewona awemvelo .

Ukuze ukhethe uhlobo lwesikrini olufunayo, udinga ukuzijwayeza ukuthi yiziphi izinqumo zezikrini ze-TV ezithengiswayo.

Yiziphi izinhlobo zokunqunywa kwe-TV ezidumile futhi ezidumile

Kunezinhlobo eziningi zezikrini kuye ngokulungiswa kanye nobuchwepheshe obusetshenzisiwe. Ukulungiswa kwesikrini okuvame kakhulu

Okulandelayo izinqumo ezidume kakhulu. Kulokhu, izici zabo eziyinhloko zizonikezwa.

Ukulungiswa 640×480

Lesi sinqumo manje asisasebenzi. Yayisetshenziselwa ama-TV okuqala anesixazululo esingu-4:3. Kunezinhlobo ezimbili: 640x480i kanye 640x480p. Esimweni sokuqala, sikhuluma ngokujwayelekile (SE), okwesibili – mayelana nokucaca okukhulayo (SD). Ngaphandle kokulungiswa okuphansi, kuyenzeka ukubuka kule khwalithi kuma-TV ane-diagonal efika kumayintshi angu-20. Kodwa-ke, akufanele ulindele isithombe sekhwalithi ephezulu nemininingwane yesithombe esihle. Ifomethi okukhulunywa ngayo isetshenziswa kakhulu uma ubuka izinhlelo zikamabonakude kumabonakude wasemhlabeni futhi akuvamile ukusetshenziselwa idijithali. Ikhwalithi ithintwa izinga lokuvuselela.
