Ukukhethwa kwamabonwakude anamhlanje kukukholisa nabathengi abafuna kakhulu, uluhlu luyakuthandekisa ingcamango. Kwaye nenani lezinto ezikhethiweyo nalo liyamangalisa. Nangona kunjalo, abantu abaninzi abathengayo i-TV abayiqwalasela into yokuba kufuneka uyibukele ukusuka kumgama othile. Ukuze ukhangele imiboniselo yakho yeTV ngaphandle kokujika kwi-oculist, kufuneka ukwazi ukuba ungakanani umgama onokuwujonga umzekelo othile weTV. Nangona kunjalo, kufuneka uqonde ukuba ukuba igumbi lakho lincinci, kodwa ufuna ukufaka ipaneli ye-plasma kulo lonke udonga, akukho nto iya kuvela kule ngcamango.
Umabonwakude nge-tube cathode-ray
Iimodeli ezininzi zeTV ezivela kwiivenkile zeefowuni zekhaya - eziqhelekileyo kuzo zonke izicwangciso, umfanekiso kwizikrini zawo ulandelwa ngethubhu ye-cathode-ray. Umgama ukusuka kwi-TV yale modeli ukuya kwamehlo kufuneka ubuncinane ubuncinane be-2-3 mitha. Ukuba umgama ungaphantsi, ubeka umngcipheko omkhulu kumonakalo emehlweni akho.
I-LCD, i-LED kunye neTV ye-plasma
I-LCD (i-crystal yamanzi) kunye neeTV ze-plasma zibhekwa njengezona zikhuselekileyo. Xa zijongwa, amehlo awanakaliswa ngukuqhaqhazela, ngenxa yokuba ayikho ngokupheleleyo. Umgama okhuselekileyo kwi-LCD TV ingaba yinto engabonakaliyo, ayinayo i-radiation eyingozi, ngoko unako ukuwajonga ukusuka kunoma yimuphi umgama olungeleyo. Akukho mfahluko phakathi komda okhuselekileyo kunye nochungechunge lweTV kwiinkalo ze-LED. Le TTV ingaqwalaselwa ngaphandle kokwesaba ukutshabalaliswa kwemitha kunye nokuqhaqhaqhaqha, okuphazamisa umbono wakho.
Njengoko usenokuba uqonde, umgama ophezulu wokubukela iTV ngqo kuxhomekeke kwimodeli yayo. Emva kwakho konke, ukuba unayo i-LCD okanye i-TV yeTV ekhaya, umfanekiso uya kucaceka kunokwenzeka nayiphi na indawo kunye nawaphi na umgama.
Kodwa nantoni na i-TV yakho, kufuneka ukwazi ukuba ukuba uhleli ngqo phambi kwesikrini, akukho nto iya kuvela kuyo. Umgama okhuselekileyo wokubukela ukusasazwa kuyo nayiphi na isethi yeTV ithatyathwa njengalingana nezodiagonal zayo ezine, eziqhelekileyo malunga neemitha ezimbini. Oososayensi baseNtshona bafika kule ngcamango emva kokuvavanywa kwamanani amavolontiya. Nangona ukuba le mfuneko ibhekiswe kwiimodeli zamandulo zeTV, zifanelekile ukuba ungayinakuziboni amehlo akho, ukujonga i-TV ibonisa ukuba isondele kwisikrini.
Indlela yokubala yokubala umgama ochanekileyo wokubukela lolu hlobo lwe-TV lunikezelwa kwitheyibhile:
I-3D TV: ukubala umgama
Ungabukela iifilimu kwifomati ye-3D namhlanje ngaphandle kokushiya ikhaya lakho. Ukuze uzalise ngokugqibeleleyo kwiziganeko ezenzeka kwesikrini, kucetyiswa ukuba ungahlali kude neTV, kodwa akuyi kuwonakalisa umbono? Iingcali ziqinisekisa ukuba ukubukela iifilimu kwifomathi ye-3D akuyikulimaza umbono womntu. Umgama ophezulu kwi- screen TV ye - 3D yinkomba elinganayo kumitha emithathu, kwaye i-angle ephakanyisiweyo ye-TV kufuneka ibe ngama-60 °. Ukuba ulandela ezi ngcebiso, imiphumo yokubukela ividiyo kwi-3D iya kufutshane nento ongayibona kwi-cinema. Qinisekisa ukuqwalasela umgangatho (isisombululo) sempahla yevidiyo. Ukuba isisombululo sevidiyo sifikelela ku-720p, ngoko kufuneka uvela kwesikrini kwimizuzu emitha ezintathu, kwaye ukuba ngaba ngu-1080p, umgama okhululekile ngowama-mitha amabini.
Ulwazi oluchanekileyo lunikwe kwitafile:
Naliphi imodeli yakho yeTV, zama ukuphepha ukubukela iTV ukusuka kumgama ongaphantsi kweemitha ezimbini ukusuka kwamehlo kwesikrini. Ukuba awuhambelani nale ngcebiso, ngoko amehlo akho aya kugqitywa ngumsebenzi wokungafuneki.
