Hi ,

How can we enable HDMI Clone feature on i.MX8M plus ..?

We have a LVDS lcd as primary display, and the same content we would like to display on the HDMI.

Regards.

Hi @Nazeer!

Thank you for contacting NXP Support!

According with i.MX Linux User's Guide, you could use the following:

• U-Boot > setenv displayinfo 'video=mxcfb1:dev=ldb video=mxcfb0:dev=hdmi,1920x1080
M@60,if=RGB24' for LVDS and HDMI dual displays
• U-Boot > setenv displayinfo 'video=mxcfb0:mxcfb0:dev=lcd,if=RGB565
video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24' for LCD and HDMI dual displays

Best Regards!

Hi Chavira,

We are using DRM based display subsystem. Do this steps suites even for that, as we are using i.MX8M plus.
