Hi @charleshuang,
Sure, I can help you with that.
Yes, the HDMI and LVDS need to be set to the same resolution in order for the Yocto Logo to be displayed full screen on both displays.
One can write code for the same. one can use to set the resolution in HDMI as well LVDS.
after setting the resolution same for the both of the interfaces
I hope this helps!
