I know imx8mq support dual display, UI display on LCD, and video display over HDMI. But is it possible to display UI both on LCD & HDMI? Thanks in advance.

Hi Zhiming,

Thanks. I remember that imx8mq-evk-dual-display.dts display UI on LCD and video over HDMI. But what I would like to do is that how to display UI both on LCD& HDMI? Do you have any idea? Many thanks.

Thanks for your reply. And may I ask some more questions? Thanks a lot.

1. Is it possible that weston shows UI on LCD and displays video over HDMI at the same time? And how to do it?

2. Does kmssink (gstreamer plugin) support hotplug? And how to do it? The gstreamer can decode and output video stream over HDMI, but when I unplug HDMI and plug in again, there's nothing output anymore from HDMI.
