Cabanga ukuthi usuzozicwilisa ekuziboneni ongeke ulibaleke, lapho yonke imininingwane iphila nemibala idansa phambi kwamehlo akho. Ukukhetha i-TV efanele kuyisihluthulelo sokuvula lokho okwenziwayo okuyingqayizivele nokuhehayo. Kodwa uhamba kanjani phakathi kobuningi bezinketho nobuchwepheshe obutholakalayo? Ungakhathazeki, silapha ukuze sikuqondise kulolu hambo olujabulisayo oluya esikrinini esihle kakhulu.
Usayizi: Thola ibhalansi ephelele
Ubukhulu bethelevishini bungenye yezinto ezibaluleke kakhulu okufanele zicatshangelwe. Akukhona nje ngokukhetha okukhulu kakhulu, kodwa ukuthola ibhalansi ephelele phakathi kosayizi wesikrini nebanga lokubuka. Umthetho ojwayelekile wesithupha ukuhlala ebangeni elingu-1,5 ukuya ku-2,5 izikhathi zesikrini esidayagonali. Isibonelo, uma une-TV engama-intshi angu-55, ibanga elilungile lokubuka lingaba phakathi kwamamitha angu-2,1 no-3,4.
Isixazululo: Gxila ekubukhalini
Ukulungiswa kusho inombolo yamaphikseli akha isithombe esisesikrinini. Uma amaphikseli engeziwe, kuba mkhulu ukucija nemininingwane yesithombe.. Njengamanje, izinketho ezidume kakhulu yilezi:
-
- I-HD Egcwele (1920 x 1080 pixels)
-
- I-4K Ultra HD (3840 x 2160 pixels)
-
- 8K (7680 x 4320 pixels)
Ngenkathi ama-TV e-8K enikeza ikhwalithi yesithombe ebabazekayo, okuqukethwe okutholakala kulokhu kulungiswa kusenomkhawulo. Kubasebenzisi abaningi, i-4K TV iyinketho enconywa kakhulu, njengoba ihlanganisa ukucaca okuhle kakhulu nokutholakala okubanzi kokuqukethwe.
Ubuchwepheshe besikrini: Khetha umpetha wakho
Kunobuchwepheshe obuhlukahlukene bokuboniswa, ngalinye linezinzuzo zalo. Ezivame kakhulu yilezi:
I-OLED (i-Organic Light-Emitting Diode)
Ama-TV e-OLED anikela ngokumnyama okujulile, imibala egqamile nama-engeli okubuka abanzi. Iphikseli ngalinye likhanya ngokuzimele, livumela ukugqama okukhethekile. Alungele amagumbi amnyama futhi kulaboabafuna ikhwalithi yesithombe ehamba phambili.
I-QLED (i-Quantum Dot LED)
Ama-QLED TV asebenzisa ungqimba lwamachashazi quantum ukuze athuthukise ikhwalithi yesithombe. Zinikeza imibala enembe kakhudlwana, ukukhanya okuphezulu nokugqama okuthuthukisiwe uma kuqhathaniswa nama-TV e-LED avamile. Ziyinketho enhle kakhulu emakamelweni akhanya kahle.
I-LED (I-Diode Ekhipha Ukukhanya)
Amathelevishini e-LED ajwayelekile futhi athengekayo. Basebenzisa ukukhanya kwe-LED ukukhanyisa isikrini. Nakuba zingafinyeleli emazingeni okuqhathanisa nekhwalithi yesithombe yama-OLED nama-QLED, zinikeza inani elihle lemali.
Izinga lokuvuselela: Uketshezi oluqhubekayo
Izinga lokuvuselela likalwa nge-hertz (Hz) futhi linquma ukuguquguquka kwezithombe ezihambayo. . Izinga lokuvuselela eliphezulu lisho isithombe esishelelayo kanye nokufiphala okuncane kuzigcawu zesenzo esisheshayo. Izinketho ezivame kakhulu yilezi:
-
- 60 Hz: Ifanele okuqukethwe okuningi.
-
- 120 Hz: Ilungele amamuvi nezemidlalo.
-
- 240 Hz noma ngaphezulu: Ilungele abathandi bemidlalo yevidiyo nokuqukethwe kwesenzo.
I-HDR: Imibala emangalisayo nokugqamayo
I-HDR (High Dynamic Range) ubuchwepheshe obuthuthukisa ububanzi obuguqukayo besithombe, inikeza imibala ecebile, emnyama ejulile nemininingwane ebukhali. Kunamafomethi ahlukene e-HDR, njenge-HDR10, HDR10+, Dolby Vision ne-HLG. Qiniseka ukuthi i-TV yakho isekela ifomethi ye-HDR oyikhethayo.
Ukuxhumana: Hlola indawo yonke okungenzeka
Ukuxhumana kubalulekile ukuze ujabulele ngokugcwele umabonakude wakho. Bheka imodeli enezimbobo ze-HDMI ezanele ukuze uxhume amadivayisi akho, njengamakhonsoli egeyimu yevidiyo, izidlali ze-Blu-ray, noma amabha omsindo. Futhi, cabangela ukwesekwa kwe-Wi-Fi ne-Ethernet ukuze ufinyelele okuqukethwe ku-inthanethi namasevisi okusakaza-bukhoma..
Imikhiqizo efakiwe: Thola umngane wakho ophelele
Eminye yemikhiqizo eyaziwa kakhulu emakethe kamabonakude yilezi:
-
- LG: Iyaziwa ngamathelevishini ayo ekhwalithi ephezulu ye-OLED.
-
- I-Samsung: Ivelele ngamamodeli ayo e-QLED kanye nohlu lwayo olubanzi lwezinketho.
-
- I-Sony: Inikeza amathelevishini anesithombe esihle kakhulu nekhwalithi yomsindo.
-
- I-Philips: Yaziwa ngobuchwepheshe bayo be-Ambilight, obunweba imibala ukusuka kusikrini iye ezindongeni.
Inani: Thola ibhalansi ephelele
Intengo kamabonakude ingahluka kakhulu kuye ngezici zayo nosayizi. Setha ibhajethi futhi ubheke imodeli enikeza inani elingcono kakhulu lemali ngaphakathi kwalolo bubanzi.. Khumbula ukuthi i-TV iyi-investimenti yesikhathi eside, ngakho-ke ungabukeli phansi izici ezibalulekile kuwe.
Ukukhetha i-TV efanele kuyisinqumo somuntu siqu esincike ezidingweni zakho, okuncamelayo, kanye nesabelomali. Cabangela usayizi, ukulungiswa, ubuchwepheshe besikrini, izinga lokuvuselela, i-HDR nokuxhumana ukuze ukutholele isikrini esihle kakhulu. Noma ngabe ubheke ukucwila emhlabeni wamasinema, ujabulele imidlalo ethokozisayo yezemidlalo, noma uhlole ama-universe amakhulu amageyimu evidiyo, kune-TV ekulindile.
Manje njengoba usuhlome ngolwazi oludingekayo, sekuyisikhathi sokuthi uqale usesho olujabulisayo lomngane wakho okahle wokulalelwayo nokubukwayo Zivumele ukhangwe umlingo wezithombe futhi uzicwilise okuhlangenwe nakho okubonakalayo okungenakuqhathaniswa.
