To switch to highest-quality component video output, follow these steps:
1) Connect your component video connectors to the connectors in a
square on the far left of the board. Instead of connecting one
connector as with composite video, connect the YPrPb connectors
as shown here.
The DVEVM kit does not include a 3-connector cable used for
component (YPrPb) video. The cable you use may have red, green,
and blue connectors, but you should be aware that the Y, Pr, and Pb
signals used by component video do not correspond to RGB signals.
In addition, you will need a video display with component video
inputs.
2) On the kernel command line, you can configure the EVM to select
both NTSC vs. PAL and the component video output format (see
Section 4.3.7, Configuring the Boot Setup for PAL Video Users). For
example, if you want both NTSC and component video output, use
the following:
If you want both PAL and component video, use the following:
Pr Pb
