Tiyeni tione zimene polojekiti ntchito mu mode malemba. Ichi ndi TV amene conventionally ogaŵikana ankadziwa. Monga ulamuliro, izo lagawidwa mizere 25 8 maudindo. Aliyense ankadziwa - mtundu wa munda zizindikiro zina anasonyeza. anthu onse 256. mwa iwo, zazikulu ndi lowercase, manambala, ndi zizindikiro zopumira, zilembo wapadera ndi Pseudographic kalembedwe. Ngati polojekiti ntchito, okhoza kubala zonse zosiyanasiyana mitundu, aliyense ankadziwa akhoza allocated wapadera mtundu lemba ndi maziko.

Tsopano taonani zimene polojekiti kusonyeza zithunzi, zithunzi wapadera ndi zinthu zina. Choyamba, dziwani kuti ntchito kuwonetsera mawonekedwe angasonyeze zolemba zosiyanasiyana zilembo wapadera ndi makulidwe. Ndipotu, mtundu amasonyeza fano ntchito pixels, ena a iwo, chithunzi bwino ndi bwino. Mfundo - ichi ndi mapikiselo. Izo zikhoza kukhala mtundu chake ndi chiwerengero cha pixels vertically ndi horizontally amatchedwa chophimba Maganizo a polojekiti yanu.

Musanagule chinthu, iwo ayenera kumvetsa kuti masanjidwewo kudzionetsera. Iwo anachita pa umisiri osiyana, ndipo Oo khalidwe chifukwa cha kukula kwa pixels (mbewu). The pixels zambiri, koyipitsitsa anasonyeza khalidwe.

Musati muphonye chophimba mtundu. Chiwerengero cha mitundu amadziwika mlingo wa khalidwe. Malinga ndi mbali luso lililonse kompyuta munthu, kuzindikira angapo likutipatsa anasonyeza modes: EGA, VGA, SVGA, LCD.

Kukhazikitsa polojekiti mmodzi wa modes awa, zithunzi accelerator, PC ayenera akhale okonzeka ndi mphamvu zokwanira kukumbukira. Today SVGA mode sagwirizana ndi mapulogalamu onse ndi madalaivala zina amene anaika ntchito bwinobwino.
