| 11-0 | WIDTH<11:0> | This is the width in pixels of the frame buffer if you draw to the frame buffer based on a different width than what is given here the image will drift with each line to the left or right. The common values are 320 and 640, the maximum value is 640. The minimum value depends on the TV set, 160 would probably be a safe minimum but no guarantee4095. The same value would also be used on drawing commands for clipping or scissors. This can also be used with High Res interlacing modes to change the odd and even lines of the frame buffer to be drawn to screen by doubling the width of this value and changing the VI_ORIGIN register to the odd or even field being displayed.
