We have reviewed the Data Manual and Reference Manual and see the following limitations 4K2K@60HZ,
But from the kernel source code, see, horizontal resolution and vertical resolution limits,
Therefore, please help to confirm whether the HDMI interface of the development board of IMX8MQ chip supports the output timing of 8Kx1K@60HZ, thank you very much!

I would like to know if the imx8mq(MIMX8MQ6DVAJZAB) chip also has the same limitations. When I use both HDMI and MIPI-DSI interfaces simultaneously, HDMI can only achieve 4K@30HZ ? Or rather, when I use both HDMI and MIPI-DSI interfaces simultaneously, HDMI can only achieve 4K@60HZ The MIPI-DSI interface can reach 1080p, thank you very much! Looking forward to your reply.

Hello,

For imx8qm hdmi support:

- HDMI -> 4K@60
For HDMI 4K@60 you have to combine DC0-0 and DC0-1, which means you lose MIPI-DSI0 and LVDS0,
conversely if you use either of those interfaces you are limited to HDMI 4K30.

It could not support 8k.

 

Regards
