Ngaphandle kokungabaza, izindonga zevidiyo zibukeka zizinhle, kodwa izici zesikhangiso, ezifaka ubude besikhathi, ukufaneleka, nokunyakaza, zingaba impahla noma icala ekubonisweni kodonga lwevidiyo ye-LED.Uma okuqukethwe kungacatshangelwa kahle noma kudalwe ngobuchule, ubusha buzoshabalala ngokushesha.Okuqukethwe okudalwe ngokobuchwepheshe, okukhangayo kuyadingeka ukuze kuzuzwe impumelelo yesikrini sokubonisa i-LED.Okwengeziwe, okuqukethwe kunquma ukuthi iyiphi ihadiwe ezodingeka.Ngaphambi kokuthenga udonga lwevidiyo ye-LED, kubalulekile ukunaka izici ezimbalwa.

Okokuqala, ukulungiswa kodonga lwevidiyo ye-LED kuthonywa usayizi walo, futhi kungathinta kakhulu isu lokuqukethwe.Uma usayizi mkhulu, ukulungiswa okuphansi.Ngakho-ke, okuqukethwe kufanele kube yi-Pixel-ephelele ekulungisweni ngokomzimba kwesikrini.Isibonelo, thatha udonga lwe-LED olwenziwe ngamaphaneli e-LED angu-30 3.9mm, abekwe ngo-10-wide kanye no-3-ubude.Uma iphaneli ngayinye ingu-500mm ngo-1000mm, futhi iphaneli ngayinye inokulungiswa kwephikseli ebonakalayo engu-128 x 256, ukulungiswa kodonga okuphelele kuzoba ngu-1280 x 768, okulenza libe udonga olu-2 x 2 olunesibonisi esingu-4K esidinga izithombe ezingu-4K (hhayi i-HD) namavidiyo.Lezi zici ezihlukahlukene kufanele zicatshangelwe lapho kukhethwa izithombe ezifanele zesikrini sokubonisa se-LED.

Okwesibili, ukwazi ibanga elijwayelekile lokubuka kubalulekile – ukwenza umbhalo ube mncane kakhulu ukuthi ungafundwa, noma ube mkhulu kangangokuthi awufiphele, kuyiphutha elivamile.Ngaphezu kwalokho, ukugqama kombala kukhulisa ukufaneleka futhi.Umklami wokuqukethwe onesipiliyoni uyabazi osayizi abalungile, izitayela, nokucija ukuze akhe izimpawu zedijithali ze-LED ezisebenza kahle kakhulu, eziphoqelelayo.

Okwesithathu, ngenkathi ukuthengiswa kwe-TV okumaphakathi kuyimizuzwana engama-30 ukuya kwangu-40 ubude, izethameli zodonga lwevidiyo zivame ukuzinyakazisa.Okuqukethwe kwesikhangiso kufanele kuhlelwe ngokufanele, kungapheli imizuzwana eyi-10 ukuya kweyi-15 lilinye.

Okokugcina, ukhiye wempumelelo yanoma yiluphi udonga lwevidiyo wukuqala okuqhubekayo.Izikhangiso eziboniswa njalo zivame ukushaywa indiva ngokuhamba kwesikhathi.Kubandakanya okuqukethwe okusha kwansuku zonke, njengesimo sezulu, amaqiniso ajabulisayo, noma izingcaphuno ezingahleliwe, kuzokhulisa ukugcwala kwamehlo, futhi kungadala ingxoxo ngodonga lwevidiyo.
