Ngexesha lokusebenza okuqhelekileyo kwescreen esingcangcazelayo, ngenxa yeempawu ezahlukeneyo kunye nemilo yezinto, iintlobo ezahlukeneyo zemingxuma yescreen ziya kuvalwa. Izizathu zokuvaleka zezi zilandelayo:
1.Iqulethe inani elikhulu lamasuntswana akufutshane nendawo yokwahlulwa;
2. Le nto inomxholo wamanzi amaninzi;
3. Amasuntswana angqukuva okanye izinto ezineendawo ezininzi zokunxibelelana kwimingxunya yesihluzo;
4. Umbane oqinileyo uya kwenzeka;
5. Izinto ezisetyenzisiweyo zinezinto ezinamathelayo;
6. Kukho amasuntswana aqhekekileyo;
7. I-mesh yesikrini esilukiweyo ityebile;
8. Izikrini ezityebileyo ezifana nezikrini zerabha zinemingxunya engafanelekanga kwaye azifikeleli kubukhulu obuphezulu nobusezantsi, nto leyo enokubangela ukuba amasuntswana abambeke. Ngenxa yokuba uninzi lwamasuntswana afunekayo ukuhluzwa alunganga, izizathu zokuvaleka nazo zahlukile.
