 ##  Your HDMI monitor may support only a limited set of formats. To find out
-##     overrides the normal selection of composite if no HDMI is detected
+##  which formats are supported, use the following method.
 ##  1) Set the output format to VGA 60Hz (hdmi_group=1 hdmi_mode=1) and boot up
 ##     the Raspberry Pi
 ##  2) Enter the following command to give a list of CEA supported modes
 ##         /opt/vc/bin/tvservice -m CEA
 ##  3) Enter the following command to give a list of DMT supported modes
 ##         /opt/vc/bin/tvservice -m DMT
 ##  4) Enter the following command to show your current state
 ##         /opt/vc/bin/tvservice -s
 ##  5) Enter the following commands to dump more detailed information from your
 ##     monitor
 ##         /opt/vc/bin/tvservice -d edid.dat
 ##         /opt/vc/bin/edidparser edid.dat
 ##
 ##     The edid.dat should also be provided when troubleshooting problems with
 ##     the default HDMI mode

 ##  Overclocking Settings

 ##  ARM, SDRAM and GPU each have their own PLLs can can be unrelated
 ##  frequencies.
 ##
 ##  The GPU core, h264, v3d and isp share a PLL, so need to have related
 ##  frequencies.
 ##  PLL will be set to:
 ##    pll_freq = core_freq * 2^n, for smallest n satisfying pll_freq > 600MHz
 ##
 ##  GPU core, h264, v3d and isp should all be integer divisors of PLL freq.
 ##  So if core_freq=480, then pll_freq=960.
 ##  That would allow a v3d_freq/h264_freq/v3d_freq of 320 with an integer
 ##  divider of 3.
