Ted,

I believe this question will be better supported in this forum.

Hi Ted,

What refresh rate do you need? Do you know the blanking timing information for the panel?

Assuming 60 frames per second, and 20% blanking overhead, the PCLK would come out to be:

1440 * 540 * 60 * 1.2 = 56MHz. Well within the 85MHz max for the 927.

If you know the Vtotal and Htotal for the panel, and the refresh rate, you can calculate the exact PCLK needed. As long as it is within the range for the 927, it will work.

Thanks,
Jason
