Table 18-5 shows how the values in this example correspond to the argument names defined in Table 18-3.
Example 18-3. 720P TV Connected to Display Port 1
For a 720P TV connected to display port 1, the kernel command is video=mxcdi1fb:YUV444,720P60
Table 18-6 shows how the values in this example correspond to the argument names defined in Table 18-3.
18.3.2 Setting the di1_primary Kernel Parameter
The di1_primary kernel parameter informs the kernel/driver that DI1 is the primary display interface
instead of DI0, which is the default setting. Set this kernel parameter by adding the label di1_primary to
the boot kernel arguments.
