Display Mirroring When Changing Resolution on Jetson Orin Nano (YDK WS-55-2K Monitor)

Robotics & Edge Computing Jetson & Embedded Systems Jetson Orin Nano
1

Hardware & Environment:
Device: Jetson Orin Nano
Display: YDK WS-55-2K connected via DisplayPort (DP-0)
Default Resolution: 2560x1440
Expected Resolution: 720x1280 or similar supported modes
OS: [Ubuntu version / JetPack version]
Driver: NVIDIA proprietary driver (via X11, nvidia-drm)

Problem:

The system defaults to 2560x1440, but I want to use another supported resolution (e.g., 1920x1080).
When I change the resolution using xrandr, the display enters a mirrored or duplicated visual state, where parts of the screen appear mirrored or repeated horizontally.
xrandr shows multiple standard resolutions, but switching to any resolution other than the default causes this mirroring problem.

xrandr command output

Hi,
Does it work if you switch the resolution through Ubuntu Setting? It is supposed to work through Ubuntu GUI.

7

No even if i change the setting using display settings i get the same but if i connect the same display to windows pc it works fine and from my system ubuntu i was able to change the resolution using nvidia settings which was also running fine but in orin i dont get that option

8

What is the result of /var/log/Xorg.0.log when you switched the mode?

Could you attach the full xorg log as text file instead of copy and paste only few lines here?

11

xorg_log.txt (16.0 KB)

12

Just want to clarify. Is “1024 x 768” the mode you expected to use? Or you don’t know where it came from..?

13

I dont know where it came from , i was not even getting these resolutions in jetson i was able to change it only in windows and normal ubuntu but when i changed my xorg.conf file i got the resolutions in jetson after which i am facing this issue
xorg.conf.txt (650 Bytes)

14

Option “UseEDID” “false”
Option “ModeValidation” “NoEdidModes”

Are these added by you? This thing should not be here.

15

Then i get only one resolution which is 1440x2560 on jetson but in windows i get mutiple

16

Could you share the xorg log in this situation?

UseEDID false is not supported on any Jetson. We only allow mode from EDID.

17

xorg_log.txt (14.3 KB)

I get only 1 mode with this which is 1440x2560 resolution , how will i get any other resolution

18

Hi,
Please do compliance test to the custom board:

Jetson Download Center | NVIDIA Developer

It there are multiple modes in EDID, all modes should be listed. It seems like the EDID is not correctly read. This may be an issue in signal quality.
