'''H_PIXELS '''
:Horizontal resolution of the display you want. For a 640x480 resolution, supply 640. Note that video cards will usually want this to be a multiple of eight because of [[#CELL_GRAN_RND|cell granularity]].
{{Anchor|PIXEL_FREQ_REQUIRED}}
'''PIXEL_FREQ_REQUIRED'''
:The speed of the dot clock (or pixel clock), in pixels per second. This is usually the same as the dot clock's frequency in Hz, but in some cases there's a factor two difference (2x the frequency when the clock is being doubled, half the frequency when pixels are emitted every other cycle) The dot clock is usually limited by the video card, as higher clocks are needed for higher framerates and resolutions.
{{Anchor|REFRESH_RATE_REQUIRED}}
'''REFRESH_RATE_REQUIRED '''
:The amount of fields per second in Hz. This is also the number of frames per second for non-interlaced modes, or twice the number of frames per second for interlaced modes.
Line 374 ⟶ 378:
'''IDEAL_DUTY_CYCLE'''
:'''Todo''' Percentage. One of the steps to compute the amount of horizontal blanking
{{Anchor|IDEAL_H_PERIOD}}
'''IDEAL_H_PERIOD'''
:'''Todo''' Optimal time to spend on a scanline
