Parallel 24 bit RGB instead of HDMI

Hello, I am developing a PCB based on Jetson nano. For the image display, I need to increase the speed of the HDMI so, a good approach will be to use a parallel RGB data (24bits desired).
I am doing it with Beaglebone native, however, this interface is not available in the Nano.
How could I reach to control a parallel video display? Thank you.

I am not pretty sure what is parallel display. Could you share detail?

Sure, Parallel RGB or also called DPI, is a parallel data communication for some displays. They can be normaly handled with 8, 16 or 24 bits.
RGB24 (8 bits for red, green and blue) or RGB666 (6 bits per colour) or RGB565 (5 bits red, 6 green, and 5 blue). And need an extra pins for vertical and horizontal sync and a clock.

My question is if there is a way to do it using GPIOs from the Nano directly.
If not, I can build an external electronics with a parallel shift register from the SPI output, but would be great if the DPI display can be connected directly.

Thank you.


If you cannot find extra pinout info in product design guide. Then it is not supported.
