/* Specifications */
*'''Mode 1''': '''320×200''' pixels with 4 colors (2 bpp)
*'''Mode 2''': '''640×200''' pixels with 2 colors (1 bpp)
*'''Mode 3''': '''160x200160×200''' pixels with 4 colors (2bpp) (this is not an official mode, but rather a side-effect of the hardware)
The Video modes are known to display pixels with different sizes.
Basically, the Amstrad CPC Video works 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 Trick (often dubbed erronuously as "[[Programming:Overscan|overscan mode]]".)
This then allows with a video memory of 24Ko 24 KB (approximately) to displays on the standard screen up to :* Full screen '''Mode 0''': '''192x272192×272''' pixels with 16 colors (4 bpp)* Full screen'''Mode 1''': '''384x272384×272''' pixels with 4 colors (2 bpp)* Full screen'''Mode 2''': '''768x272768×272''' pixels with 2 colors (1 bpp)
Also the use of scanlines to increase vertical resolution is not "easly" possible on Amstrad CPC.
