      Hello,

      I already had the same issue with Recalbox 7.0, but it was fixed with the 7.1 version (I didn't really search for a fix at this time). The issue comes back with the 7.1.1 version.

      When I play with emulators (Snes, Genesis, PC engine...): I have sound glitches and the command don't respond correctly... I discovered that the vertical refresh rate is set to 60Hz, but the reported display refresh rate is set to 50hz.

      With the previous version I have this and all is working perfectly:

      I try to find a fix and discovered that it's related to the screen detection, but I did not find the way to set the it correctly.

      The xandr report give me this:

      Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
      DP1 disconnected primary (normal left inverted right x axis y axis)
      HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 820mm x 460mm

         640x480       75.00    72.81    60.00    59.94
         720x400       70.08
      HDMI2 disconnected (normal left inverted right x axis y axis)
      VIRTUAL1 disconnected (normal left inverted right x axis y axis)
      

      And if I run the following command, the settings are ok:

      xrandr -r 60
      

      I tried to add this setting in the recalbox.conf with no success:

      global.videomode = CEA 16 HDMI
      
      

      If anybody can help me to fix this πŸ™‚

      My system:

      • Recalbox 7.1.1 X64
      • PC/NUC Model : CORE I3-4010U HD 4400 4Go (NUC D34010WYK)
      • USB Key SanDisk UltraFit

      Thanks for your help.

        Try to edit /etc/X11/xinit/xinitrc file and in a new line, add your xrandr command.

          I have updated the xinitrc file but it does not fix the issue.

          I also changed the /usr/bin/externalscreen.sh call by removing the '&' to be sure that the script has ended when the new xrandr command starts.

            I move the xrand line from the end of the file to the next line after the externalscreen script call and now it works πŸ™‚

            #/usr/bin/externalscreen.sh &
            /usr/bin/externalscreen.sh
            xrandr -r 60
            
            

            Thank you for your help πŸ™‚
