And if 'm' is 39specified, add margins to the calculation (1.8% of xres rounded down to 8 40pixels and 1.8% of yres). --- 139 unchanged lines hidden --- | 36 37If 'M' is specified in the mode_option argument (after <yres> and before 38<bpp> and <refresh>, if specified) the timings will be calculated using 39VESA(TM) Coordinated Video Timings instead of looking up the mode from a table. 40If 'R' is specified, do a 'reduced blanking' calculation for digital displays. 41If 'i' is specified, calculate for an interlaced mode.
