Ukuthenga i-TV entsha kuyinto entle, kodwa ayikho into elula. Kufuneka uthathe isigqibo malunga nohlobo lweskrini: i-crystal yamanzi okanye i-LED, umenzi oqinileyo kunye nexabiso. Emva kokuba ufumaniswe neminqweno kule miba, kufuneka uphendule enye into: njani ukhetha ukudibanisa kweTV? Kubonakala ngathi kunokuba lula, kuba isikrini esikhulu eludongeni - akusilo iphupha? Kodwa akusiyo yonke into engabonakaliyo. Xa ukhetha ukudibanisa kweTV, umgaqo othi "uphelele ngakumbi" akusoloko uqinisile.
Indlela yokulinganisa idayagonal yeTV kunye nento yokuthembela xa uyikhetha?
I-diagonal ithathwa njengowomgama phakathi kwe-diagon engqamene neekona zesikrini. Ilinganiswa ngamasentimitha. I intshi i-2.54 cm, ngoko emva kokubala okulula unako ukugqiba ubungakanani bokudibanisa kunye neentimitha.
Ukuba uthengisa imodeli emitsha, yangoku, ngokuqinisekileyo uya kuzibuza: ii-diagonals zeTV: ziphi na? Ngokungathandabuzekiyo, kubavelisi abahlukeneyo bangalingani, kodwa ngokuphindaphindiweyo banamathela kumgangatho oqhelekileyo owamkelekileyo. Ngoko, ekuthengiseni kunokwenzeka ukufumana iiTV nge-diagonal ye-17, 19, 22, 25, 37 kunye nokunye ngokukhawuleza. Ngoko ngubani na onokulungele?
Ukuchonga uhlobo luni lwe-TV olukhethiweyo lokukhetha, kufuneka ujolise kwizinto ezimbini:
- ubukhulu begumbi apho ukuthengwa kucetywayo kwaye, ngokufanelekileyo, umgama oza kubonwa ngawo;
- Uhlobo lweskrini kwaye, ngokufanelekileyo, isisombululo sayo.
Emva kwezifundo ezininzi, iingcali zoshishino zicebisa okulandelayo:
- I-TV kunye neskrini seemitha ezili-14 ukuya ku-17 kufuneka ibhekiswe ubuncinane kwimitha ukusuka kubo;
- Ukubukela ngokukhululekile kweTV kumaninzi - ukusuka
26 ukuya kuma-32 intshi, kufuneka uhlale phantsi kwi-2-2,5 m; - Ukuba uthatha isigqibo sokuthenga i-TV enkulu, u-diagonal wama-intshi angama-61-80, ubukhulu bezindlu zakho kufuneka kukuvumele ukuba ubukele ukusuka kumgama we-4-5 m.
Ngokuphathelele uhlobo lweskrini, kulo mzekelo, akuyiyo kuphela induduzo yakho, kodwa ubukhulu bomfanekiso buxhomekeke ngqo kubukhulu bayo. Ngoko, ukufumana umfanekiso ophezulu kwi-screen LCD, kufuneka ukhethe ukudibanisa okungenani ii-intshi ezingama-26. Njengemizekelo yeTV-TV exhasa umfanekiso wesithathu, ubuncinane be-diagonal kufuneka bube ubuncinane obungama-intshi ama-40. Nangona kunjalo, awukwazi ukufumana oko kuthengiswa.
