HDMI resolution effected when we enabled LVDS display

Hi,

IMX8MP Android 13 we have build the bsp based on user guide.

We were able to see full resolution on HDMI ,while HDMI was only enabled.

When we enabled LVDS support in the BSP, we observed that the LVDS resolution had an impact on the HDMI resolution.

When LVDS is enabled in the Android BSP, is it possible to attain full resolution on HDMI?

Are you using lvds-panel dtbo.image?

To test LVDS panel display, execute the tool with -d lvds-panel. MIPI-to-HDMI and physical HDMI
are also supported in this condition

Best Regards
