Tam sim no, cov kua siv lead ua kua zaub yooj yim yog muaj ob hom: D-Sub (kuj hu ua VGA) thiab DVI. Cov D-Sub interface tau pom tshwm hauv cov khoom qes kawg, thiab xav tau kev hloov ua ob-rau-analog thiab analog-rau-digital conversion los hloov cov teeb liab ob zaug, thaum DVI interface yog cov teeb meem uas tsis muaj teeb meem tag nrho, uas mas pom tshwm hauv high-end khoom.
Vim tias qhov DVI interface muaj cov digital, cov duab yuav tsis tshwm sim tuaj yeem tshwm. Vim tias D-Sub interface yog simulation txujci, nws muaj xws li tsis ruaj tsis khov, ces nws yuav inevitably coj tej teeb meem rau peb siv.
Thaum LCD siv D-Sub interface ntev, cov nyhuv yuav ploj mus. Nws yog qhov tsim nyog kom rov tswj cov khawm siv feem ntau pib siv qhov qub nyhuv (tab sis qhov kev siv tiag tiag muaj qhov nyhuv me me, Kuv tabtom siv nws). Txawm li cas los xij, cov kua dej ua kua ntawm DVI qhov txuas yuav tsis pom zoo rau qhov teeb meem zoo li no, thiab cov nyhuv tso tawm zoo li qub tom qab siv sijhawm ntev lawm. Nyob rau hauv cov ntaub ntawv ntawm comparable hnav, peb yuav tsum xav txog lub LCD nrog DVI interface.
