      Hello, my tv is hd (1360x768) connected with a raspberry pi 4 and I have problems with blackscreen (no signal), I had changed this parameters in config.txt file :

      uncomment to force a specific HDMI mode (this will force VGA)

      hdmi_group=2
      hdmi_mode=39

      And now I have solved the problem, but when I want to change to kodi I have the same problem with blackscreen (no signal video).
      thanks for yours answers!

            for kodi, @gabo

            what controller pad ? xbox360 ?

            turn off your controller, and with virtualgamepad on your smartphone, try again to launch kodi please.

                @gabo I had updated to 7.0.1 but the problem is the same: black screen. Only changed was the boot plash screen.

                  Hello, same problem installation v7.0.1 in RPI4 and no video signal. I have a signal if I start by disconnecting HDMI cable and then connecting it.

                    @gabo Only on Kodi do you have a black screen then?
                    Have you tried modifying kodi.videomode in Recalbox.conf?

                    @key_deep2 Apparently you need to configure the video output in the config.txt file as gabo quotes in the first post (but with the parameters corresponding to your screen). For more information, read:

                        @Zing thanks for your answer, but i still have the same problem.
                        On a new Pi 3 Mod. B + installation with v7.0.1 (for pi3) no problem. Boots without modifying config.txt in DMT 81 (preferred resolution).
                        In a new Pi 4 installation with v7.0.1 (for pi4) the intro videos are seen, then black screen.

                        tvservice pi4.png

                        I can't get it to boot into DMT by modifying config.txt
                        hdmi_group = 2
                        hdmi_mode = 81
                        I only get it to boot by forcing VGA with hdmi_safe = 1 or with hdmi_group = 1
                        hdmi_group = x
                        I've tried different HDMI cables in case it was a cable problem.

                          you can try this command to list all screens

                          DISPLAY=:0.0 xrandr
                          

                          Edit /etc/bin/X11/xinit/xinitrc under the line # xrandr --output output_name --off the line with your TV entry
                          comment the line beginning by /usr/bin/externalscreen.sh &

                          For example, i have two screens LVDS-1 : my laptop screen and my TV identified by DP-0
                          I added this line

                          xrandr --output LVDS-1 --off --output DP-0 --mode 1920x1080
                          

                          Then reboot your rpi4

                              There is no xinitrc and xrandr on rpi... The issue seems to be on rpi, not on PC which have xinitrc and xrandr.

                              And xinitrc is on /etc/X11/xinit, there is no bin directory.

                                @Pitch64 It seems that way, my problem is that I give it two uses: in a room with a 22 "monitor for me and in the living room with the TV to play the children ..., I won't be able to use the pi4 for me. Thank you for your support

                                    @zamalek89 I have been able to start Recalbox on a 1366x768 monitor in the following way:
                                    You put the microSD into the PC, open the "recalbox" unit, you will find several files, edit "config.txt" (notepad works).
                                    You change the lines:
                                    #hdmi_group = 1
                                    #hdmi_mode = 1
                                    by:
                                    hdmi_group = 2
                                    hdmi_mode = 39
                                    and save modifications. With these changes, it will start in 1360x768 resolution and recalbox will work without a problem, the bad thing is that you will not be able to switch to kodi, you will get a black screen.
                                    I have tried modifying kodi.videomode in the "recalbox.conf" file but have not succeeded in getting it into kodi.
                                    ** important ** that configuration only works for that monitor, if you start with that configuration on any TV it will not work

                                        @zamalek89 Try to enter kodi:

                                        • While in Recalbox, disconnect the HDMI cable.
                                        • Press X to enter kodi.
                                        • Wait a moment for it to enter kodi.
                                        • Connect the HDMI cable
                                          Not a solution, but it works
