How to set HDMI out resolution to 1080i60 for Orin NX

We have a requirement to support 1080i60 or 1080i50 on HDMI output,
My monitor supports 1080i and I made sure the EDID has been confirmed.
Via xrandr but there is no 1080i information.
I tried to use xrandr to add new mode with 1920 x1080

xrandr --newmode 1920x1080_60.00i" 74.25 1920 2008 2052 2200 1080 1084 1090 1125 -hsync +vsync interlace

Then, the next command addmode always returns the error message as follows

X Error of failed request : BadMatch (invalid parameter attributes)
Majoy opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 23
Current serial number in output stream: 24

The information about my system is as follows :

NVIDIA Jetson Orin™ NX 16GB
Kernel : 5.10.120
BSP : Linux for Tegra(L4T) R35.3.1
SDK : JetPack 5.1.1

I would appreciate any helpful assistance, Thanks

Adding mode is not allowed on Jetson. Also, we don’t support interlaced mode.

I appreciate for your quick reply.
Is there any wrokaround feasible?
I would like to ask whether this is blocked by driver or not supported by hardware.

Regarding adding mode, you mean we can’t customize any resolution, even in pogressive

Thank you.

  1. Jetson never supported interlaced mode before.

  2. Yes, customizing a resolution is not allowed. We only support a customized EDID.
