32:9 SuperWide Curved Monitor with wrong resolution

[David D.]

I connected a 49" super wide curved monitor (philips 49b2u5900) to opi5+ through HDMI. I would expect to have the possibility to choose between resolutions of 5120x1440 or 3840x1080. Unfortunately I only get 16:9 resolutions.

 

 v24.8.4 for Orange Pi 5 Plus running Armbian Linux 6.1.75-vendor-rk35xx

 Packages:     Ubuntu stable (noble)

david@orangepi5-plus:~$ xrandr
Screen 0: minimum 16 x 16, current 3840 x 2160, maximum 32767 x 32767
HDMI-1 connected 3840x2160+0+0 (normal left inverted right x axis y axis) 1190mm x 340mm
   3840x2160     59.98*+
   2048x1536     59.95
   1920x1440     59.97

 

How can I configure the proper resolution? I as have little experience with this kind of problems and other similar issues were years ago reported I thought to open a new topic. Thanks for any reply.
