Assistance needed: display resolution issue on A603 Jetson Orin NX Jetpack 6.0

Products & Technology Single Board Computers
#1

Hi all,

I am trying to setup my A603 carrier board with my Jetson Orin NX 8GB module. I have flashed my system with Jetpack 6.0 as per the instructions given on: A603 Carrier Board | Seeed Studio Wiki

When I connect my screen to the hdmi port, the maximum resolution I can select is 1920x1080.

I have also tried flashing Jetpack 5.1.2 and it works perfectly, higher resolutions are being detected for my screen. Unfortunately I need Ubuntu 22.

I am happy to provide command outputs or any other information that might be helpful.

Thank you all for your help!

You can use xrandr to manually set a higher resolution.

Hi, thanks for your reply. I have already tried but it’s not working. Not sure if I’m doing things right though. Here’s what I did:

xrandr

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 800mm x 330mm

   1600x1200     60.00  
   1280x1024     75.02    60.02

For reference, under Jetpack 5.1.2, xrandr only shows HDMI-0 with correct resolutions detected. Not sure how HDMI-0 became DP-0 and DP-1 under Jetpack 6.

Thanks!

I think it’s a bug in the area of J401 because it has only HDMI. DP for sure comes from DisplayPort.

Perhaps a proper config for JP6 is needed.

Thanks for your reply. Any idea how to fix it?

No, for the moment, but for this kind of stuff the user @ Seeed_Seraphina is most helpful
