Ukuthenga i-TV entsha kuyinto enhle, kodwa hhayi elula. Udinga ukunquma ngohlobo lwesikrini: i-crystal noma i-LED, umkhiqizi oqinile kanye nentengo. Ngemuva kokuba ukhonjiswe izifiso kulezi zinkinga, kufanele uphendule okunye: kanjani ukukhetha ukudibanisa kwe-TV? Kubonakala sengathi kungaba lula, ngoba isikrini esikhulu odongeni - akuyona yini iphupho? Kodwa akusikho konke okungaqondakali. Uma ukhetha i-diagonal ye-TV, isimiso esithi "okungcono kakhulu" akusiqiniso ngaso sonke isikhathi.
Indlela yokulinganisa i-diagonal ye-TV nokuthi yini okufanele ithembele lapho uyikhetha?
I-diagonal ibhekwa njengokungathi ibanga eliphakathi kwe-diagonally emaphethelweni e-screen. Ilinganiselwa ngamasentimitha. I-inch engu-2.54 cm, ngakho-ke emva kokubala okulula unganquma ubukhulu be-diagonal no-centimeters.
Uma uthengisa imodeli entsha, yesimanje ngokokuqala ngqa, ngokuqinisekile uzozibuza: i-diagonals ye-TV: iyini? Ngokungangabazeki, kubakhiqizi abahlukene abalingani bangase bahluke, kodwa kaningi bahambisana nesilinganiso esivunyelwe ngokuvamile. Ngakho-ke, ekuthengiseni kungenzeka ukuthola ama-TV ane-17, 19, 22, 25, 37 nokunye okuqhubekayo njalo njalo. Ngakho yikuphi okulungile kuwe?
Ukunquma ukuthi yiluhlobo luni lwe-TV oluthinta ukukhetha, udinga ukugxila ezintweni ezimbili:
- ubukhulu bekamelo lapho kutholakala khona ukuthengwa futhi, ngokufanele, ibanga elizobheka ngalo;
- Uhlobo lweskrini futhi, ngokufanele, isinqumo salo.
Ngemva kokucwaninga okuningi, izimboni zemboni ziphakamisa isilinganiso esilandelayo se-diagonal-distance:
- Ama-TV anesibuko samamitha angu-14-17 kufanele abhekwe okungenani imitha evela kubo;
- ukubuka ngokukhululekile kwama-TV kuningi-kusuka
Amasentimitha angu-26 kuya kwangu-32, udinga ukuhlala phansi kakade ku-2-2,5 m; - uma unquma ukuthenga i-TV enkulu, ukulingana kwamasentimitha angu-61-80, ubukhulu bendlu yakho kufanele buvumele ukuyibukela ibanga elingama-4-5 m.
Ngokuqondene nohlobo lweskrini, kulokhu, akugcini nje induduzo yakho, kodwa futhi ikhwalithi yesithombe incike ngokuqondile ngobukhulu bayo. Ngakho, ukuthola isithombe sekhwalithi ephezulu kwesikrini se-LCD, kufanele ukhethe ukudonsa okungenani okungama-intshi angu-26. Ngokuqondene namamodeli we -TV-TV esekela umfanekiso wesithathu, ubude obuncane bokuba kufanele bube okungenani amasentimitha angu-40. Noma kunjalo, awuncane amathuba okuwuthola ekuthengisweni.
