      I have a freshly installed RetroPie image on a RPi 4 with the following display configuration.

      • HDMI 0 - A 24” 1080p monitor
      • HDMI 1 - A Waveshare 11.9” display

      As noted in the Waveshare wiki the default orientation of the display is vertical. I’d like to rotate the display to be horizontal so I can use it as a dynamic marquee. The Waveshare wiki suggests using the Screen Configuration Utility but that obviously doesn’t work for a RetroPie image. Similarly xrandr isn’t available either.

      My searches on the web aren’t turning up much and whatever I do find is antiquated information such as only applying to RPi 3 and before or older display drivers.

      Is there anyway I can change the orientation of the secondary display?

      Thanks!

      Here are the particulars:

      Pi Model: RPi 4B
      Power Supply used: Official Raspberry Pi Power Supply
      RetroPie Version Used: 4.8
      Built From: Installed via official Raspberry Pi Imager
      USB Devices connected: None
      Controller used: Keyboard
      Error messages received: N/A
      Verbose log (if relevant): N/A
      Guide used: N/A
      File: N/A
      Emulator: N/A
      Attachment of config files: N/A
      How to replicate the problem: See above

        On a Pi4, AFAIK there's no option outside of xrandr/arandr, which require a desktop env to function.

          @mitu Have never tried it, but as boot/config.txt options can be set per display-port (0/1) and at least if kms is used instead of fkms display_hdmi_rotate should be worth a try - but I am not sure what's nowadays status is in regards of retropie & kms as the video driver.
