      Hi Folks
      I have played around with this for hours on end. I have the Raspi up and running and have got MagicMirror installed. But for the love of money I can’t get the screen to stop overflowing past the edge of the monitor. The image I can see if too big for the screen i am using.
      In Raspi Configuration I have tried Underscan both Enabled and Disabled.
      In the config file i have tried allsorts of combinations of the following code…

      disable_overscan=1
      
      overscan_left=39
      overscan_right=39
      overscan_top=25
      overscan_bottom=23
      framebuffer_width=1920
      framebuffer_height=1080
      hdmi_group=1
      hdmi_mode=16
      

      Whether disabled or not, positive or negative values nothing makes any difference the the results I get.
      Its like a setting somewhere is overriding any of these settings.
      Can someone please take pity of a guy whose gonna rip his hair out anytime soon.
      Best Regards

          @sdetweil It is the Pi desktop that is too big mate. but equally makes the MM too big too when launched.

              See these URLs for details, if not known already:
              https://www.raspberrypi.org/documentation/configuration/hdmi-config.md
              https://www.raspberrypi.org/documentation/configuration/config-txt/video.md

              Can you try this ?

              $ tvservice -m CEA
              $ tvservice -m DMT
              

              This will give you the hdmi_group that can be used and the preferred hdmi_mode.

              hdmi_group=1
              hdmi_mode=16
              

              This means CEA 1080p @60Hz.

              And what happens when you comment out disable_overscan and the overscan settings ?

              MagicMirror version: 2.30.0
              Raspberry Pi 4 Model B Rev 1.5 (8 GB RAM)
              Raspbian GNU/Linux 12 (bookworm)

              Test environment:
              MagicMirror version: v2.30.0
              Raspberry Pi 3 Model B Plus Rev 1.3 (1 GB RAM)

                Hi buddy,
                I tried disabling out all overscan settings etc. It didn’t make the slightest change, neither did…

                hdmi_group=1
                hdmi_mode=16
                

                I am not sure where i should be putting…

                $ tvservice -m CEA
                $ tvservice -m DMT
                

                I checked out those links and nothing I do at all makes any change whatsoever. I see no adjustment or anything. I’d be happy if i did then i could keep adjusting, rebooting, and re-adjust accordingly until it was right.

                THankyou for your time anyway trying to help me sort this. I really appreciate it.
                BR

                  They are not config entries.
                  Just execute those commands from the command-line.

                  The config file entries in your first post, are they yours or just an example ?

                  Let’s start with the tvservice commands.
                  Please post the output, then we take it from there.

                  $ tvservice -m CEA
                  $ tvservice -m DMT
                  $ tvservice -s
                  

                  Not an expert on the topic, but who knows we straighten this out together :-)

                    Sometimes you can fix/set overscan in the menu of the monitor, may be this helps?

                      @cirdan It was displaying fine with a black border actually during the Raspi setup and I ticked something during setup and its been like this since.
