'''Todo''' Equals 550
==== MARGINS_REQUIRED ====
Normally, the overscan area only adds unnecessary ballast to the video signal, but you can add them and that way you can set the border of your screen to something.
==== INTERLACE_REQUIRED ====
There are two kinds of video modes, interlaced and progressive modes. Progressive modes display the full frame in one go, while interlaced modes display each other scanline in each run, taking two frames to render the complete picture. Normally, you don't want this, and several video cards don't support it, so you will normally want to supply '''false''' here.
==== V_PIXELS ====
Vertical resolution of the display you want. For a 640x480 resolution, supply 480.
==== 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]].
