The HDMI resolution is incorrect on some LCD screens during UEFI menu

We found that UEFI menu resolution is incorrect on some of LCD monitors
And before into ubuntu desktop , it will show “Out of Range”
But it will be correct after into ubuntu desktop.
Could you please tell me how to fix this issue.

What’s the resolution on those monitors?
With devkit or your custom carrier board?

Is this purely HDMI or DisplayPort? No adapters on the cable (except perhaps DisplayPort to HDMI)?

1.It can support 4K resolution, after enter the ubuntu os , it will be 4K .
2.custom carrier board , and we use HDMI

purely HDMI

Hi tim,

What’s your Jetpack version in use?
Does this issue happen only with 4K monitor?

Please also share the full serial console log for further check.

1.Jetson 5.1.2
2.Yes , only happended with 4k Monitors , but not all of the monitors . We have tested about 10 monitors , the fail rate is 40%. (37.2 KB)

We would need to check debug messages in UEFI.

Could you refer to the following instruction to build debug UEFI binary (uefi_Jetson_DEBUG.bin)?

Hi Kevin,

Sorry for the late reply
The debug messages includes two monitors log (77.8 KB)

It seems there’s no HDMI for AGX Orin by default. (only DP available)

Are you porting the HDMI for your custom carrier board?
Have you tried if the DP port has the same issue?

Could you reproduce the same issue on the AGX Orin devkit with JP5.1.2(R35.4.1)?

1.We only have hdmi port on our custom board
2.So the UEFI debug message doesn’t show any useful information?

Could you share the result of the following commands on your board?

$ cat /etc/nv_boot_control.conf
$ cat /etc/nv_tegra_release

It seems the current messages not enough to debug display issue, you may need to enable more logs for further check. Let me check above information from you first.

Could you reproduce the same issue on the AGX Orin devkit with JP5.1.2(R35.4.1)?

We don’t have too many DP monitors , we will test devkit later and update to you
