1. Ikhadi lezithombe (Ikhadi levidiyo, ikhadi lezithombe) Igama eliphelele lekhadi lesikrini sokubonisa, elaziwa nangokuthi i-adaptha yokubonisa, liyilungiselelo eliyisisekelo kakhulu futhi lingenye yezesekeli ezibaluleke kakhulu zekhompyutha.
Njengengxenye ebalulekile yomsingathi wekhompyutha, ikhadi lehluzo liyithuluzi lekhompyutha lokwenza ukuguqulwa kwesiginali yedijithali ibe yi-analog, futhi lenza umsebenzi wokukhipha nokubonisa ihluzo;
 

2. I-monitor iyidivayisi ye-I/O engeyekhompyutha, okungukuthi, idivayisi yokufaka nokukhipha. Iyithuluzi lokubonisa elibonisa amafayela athile e-elekthronikhi esikrinini ngedivayisi ethile yokudlulisa bese liyibonisa emehlweni omuntu. Isikrini simane nje siyidivayisi yokubonisa futhi asihlanganyeli ekucutshungulweni nasekuguqulweni kwedatha;
 
3. Ikhwalithi yekhadi lezithombe izothinta ngqo umphumela wokubonisa wesikrini, futhi ukwehluleka kwekhadi lezithombe kuzoholela esikrinini esibi, isikrini esiluhlaza okwesibhakabhaka, isikrini esimnyama nezinye izimo ezimbi;
 
4. Ikhadi lezithombe lihlobene nesinqumo kanye nesikhathi sokuphendula kwesibonisi; ikhadi lezithombe eliphezulu lifakwe imonitha enesinqumo esiphezulu; ikhadi lezithombe eliphezulu likhipha isinqumo esiphezulu;
 
5. Ikhwalithi yekhadi lezithombe ithinta isivinini, imisebenzi yokudlulisa kanye nokucubungula ikhadi lezithombe ukucubungula izithombe, futhi isikrini sokubonisa sisetshenziswa kuphela njengedivayisi yokukhipha isibonisi.
