The standard [[video modes]] or '''Screen Modes'''.
 
As a Colour Personnal Computer, the Amstrad CPC better strength was his video capability. Yet this was also heavier for the Z80 to handle compared to other lighter diplayers such as ZX Spectrum.
 
Also Amstrad's Video RAM was shared on the Z80 RAM. This and a cheap conception with the fewer specific chip to ease the CPU could turn it into a sluggish snails if badly programmed.
 
Yet colourfull games with few scrollings requirement, reflexion games such as KLAX... were perhaps the easiest medium for a CPC to shine above other 8 bit computers.
 
Too bad too few graphicaly-heavy RolePlayingGames were produced.

Basically, the Amstrad CPC Video work like a CGA video card from a PC. But extra features like a 16 colours mode exist.
 
The dimensions in pixels given could be raised with clever use of FullScreen Mode.
 
This then allows with a video memory of 24Ko (approximately) to displays on the standard screen up to :
* Full screen '''Mode 0''': '''192x272''' pixels with 16 colors (4 bpp)
* Full screen'''Mode 1''': '''384x272''' pixels with 4 colors (2 bpp)
* Full screen'''Mode 2''': '''768x272''' pixels with 2 colors (1 bpp)
 
Also the use of canline may increase vertical resolution.
