We have connected a 600x1024 screen to our self-developed motherboard, which displays normally when entering the system desktop. However, it does not display in the UEFI and kernel stages. How can UEFI customize the output display resolution of 600x1024?
Hi 659860569,
What’s your Jetpack version in use?
I think it would still show the logo but with unexpected ratio.
Could you share the full serial console log with debug UEFI binary?
and also the logo file you are using.

What I want to ask is whether UEFI can support a resolution of 600x1024，thanks.
May I ask how the confirmation result of the problem is？

Please give me some time to check with internal if UEFI could support this resolution. (600x1024)
Sorry for the late reply, I’ve confirmed this with internal that the resolution(600x1024) is not supported in UEFI on Jetson since it is not a UEFI-compliant resolution.
Found 600x1024
GraphicsOutput 640x480
StartLineX is 10, StartLineY is 20, LineDeltaY is 20.
PosX is 10, PosY is 0
GOP is Hor 640 x Ver 480.
From the log, this looks like the UEFI GOP driver did not find a supported resolution so it did a fallback to 640x480 “safe” timing.
