        Actually it is working as expected as this screen does not own a scaler see : https://www.adafruit.com/product/2260. You need to configure it manually in the/boot.conf.txt and force the resolution. It is described in the wiki here https://github.com/recalbox/recalbox-os/wiki/TFT5-Screen-HDMI-(EN) and here at adafruit https://learn.adafruit.com/adafruit-5-800x480-tft-hdmi-monitor-touchscreen-backpack/raspberry-pi-config

        # uncomment if hdmi display is not detected and composite is being output
        hdmi_force_hotplug=1
        
        # uncomment to force a specific HDMI mode (here we are forcing 800x480!)
        hdmi_group=2
        hdmi_mode=1
        hdmi_mode=87
        hdmi_cvt=800 480 60 6 0 0 0
        
        max_usb_current=1

            ok you'll need to modify the recalbox.conf like that :

            global.videomode=default
            

            to use the default configuration from the config.txt

                Don't know, perhaps it comes from the screen. I have this problem on a 19" lcd screen too. Need to investigate further!

                    Is that line linked to the audio through hdmi ? Such things happen on DVI

                      @subs +1 my screen with this violet border is connected with HDMI-DVI cable.

                        @Tick-Lpsk which sound output are you using? You should give a try by disabling HDMI audio (please check the DVI wiki)

                          @subs thanks a lots bro
                          it work great now
                          i take a tut from here
                          https://github.com/recalbox/recalbox-os/wiki/Connect-your-recalbox-to-a-DVI-screen-(EN)
                          no more violet line 🙂

                          then i wonder can you get rid of buzz sound / white noise (mostly in the menu)
                          when i put a headphone in. I can hear i really loud
                          and i already search the forum
                          there is no answer 😞

                              Do we need to purchase that extra part from Adafruit in order for it to work?
                              It covers all the GPIO and I would need that for an arcade like box for myself?

                                Works perfectly with all emulators except n64. Keeps crashing.

                                I wrote this in the Recalbox.conf

                                n64.videomode=default

                                  Hello friends, thank you very much for the information has been very useful.
                                  I paste the code in the config.txt and everything works fine except the color on the screen is not good.0_1490860947127_IMG_1253.jpg
                                  Does anyone know how to change this?

                                    @ian57 hello, have the same problem with the same screen, but modify the recalbox.conf doesn't change anything (adding global.videomode=default). Have an advice? Thx

                                      It seems to be a known problem : http://www.robohara.com/?p=8047 and here https://retropie.org.uk/forum/topic/3191/color-issue-reds-appear-blue-etc/3, read carefully and test the proposed settings.
