"The Spectrum's video output was through an RF modulator and was designed for use with contemporary portable television sets, for a simple colour graphic display. Text could be displayed using 32 columns ×ばつ 24 rows of characters from the ZX Spectrum character set, with a choice of eight colours at two levels of brightness, which gave 15 shades (black was the same in both modes).[3] The image resolution was ×ばつ192 with the same colour limitations."

"The screen was text only, 32 characters wide by 24 high. However blocky graphics with a resolution of 64 by 48 pixels were possible by the use of the PLOT command, which ingeniously selected among a set of 16 graphics characters."
