 Most home and basic office computers suffered from the use of the old scanning method, with the highest display resolution being around 640x200 (or sometimes 640x256 in 625-line/50 Hz regions), resulting in a severely distorted tall narrow pixel shape, making the display of high resolution text alongside realistic proportioned images difficult (logical "square pixel" modes were possible but only at low resolutions of 320x200 or less).Solutions from various companies varied widely.Because PC monitor signals did not need to be broadcast, they could consume far more than the 6, 7 and 8 MHz of bandwidth that NTSC and PAL signals were confined to.
