This then allows with a video memory of 24 KB (approximately) to displays on the standard screen up to :
* Full screen '''Mode 0''': '''192×272''' pixels with 16 colors (4 bpp)
* Full screen'''Mode 1''': '''384×272''' pixels with 4 colors (2 bpp)* Full screen'''Mode 2''': '''768×272''' pixels with 2 colors (1 bpp)
Also the use of scanlines to increase vertical resolution is not "easly" possible on Amstrad CPC.
When dealing with Full screen on real Hardware, the vertical limit of 256 pixels is the "safely displayed zone". As the actually displayed zone may vary depending the time your monitor ran (warmed ?) or from individual hardware to another. The same goes for horizontal diplay as we deal with old electronic.
