      Can you do commands in the terminal ?
      Can you post the output of "xrandr" ?
      Perhaps there is a lead, in there.
      Just type "xrandr" like this :

      pi@raspberrypi:~ $ xrandr
Screen 0: minimum 320 x 200, current 1600 x 900, maximum 7680 x 7680

        The outcome is quite funny:

        Can't open display

        That's all what the terminal is giving me back.

          Oh yea sorry, I forgot, you can't run xrandr without X-windows/xinit.
          As you do not have a desktop environment.
          So in this state, this output is ok.

          We have to do it a bit different.
          Can you add a line in /opt/retropie/configs/supermodel/emulators.cfg :

          xrandr = "XINIT:xrandr"

          And when you boot a rom select this line at launch.

          Now the output of xrandr will show in :
          /dev/shm/runcommand.log

              Thanks.

              There are a few things I see.
              xrandr only sees 1 resolution.
              And I don't have this :
              SDL_VIDEO_KMSDRM_CRTCID=87 SDL_VIDEO_KMSDRM_MODEID=37

              Well, I have to think about that.
              Not really sure where to look.
              I think I will hook up a TV and see what my output is.

              I will look at it tomorrow again and it can take a while before I respond to it.

                  This may happen because you modified config.txt and instructed the bootloader to ignore the display's EDID. Did you edit the config.txt file ? Then post the contents here - surrounded by code tags (```).

                    thanks for your help. ive defiantly altered the config file because of overclocking, which runs stable. ive also tested supermodel without oc whivh was even slower. here is the config:

                    # For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=82

hdmi_ignore_edid_audio=1
# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800
over_voltage=8
arm_freq=2147
gpu_freq=750

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable infrared communication.
#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

[all]
#dtoverlay=vc4-fkms-v3d
#overscan_scale=1
gpu_mem=64

                      @phialek Any reason you've added the hdmi_group/mode options ? Comment them, along with the hdmi_force_audio_edid=1 and try again. If you have a Pi4, the gpu_mem is also redundant and it's not needed (default is 76M).

                        I think i was trying to rotate the screen in moonlight, but i don't remember that really.

                        Can i just delete the hdmi group and hdmi mode comments there?

                          Good call of @mitu.
                          Actually I was thinking a bit in the same area, yesterday.

                          I would not delete the lines just comment them with # .
                          Your pi should boot if you comment those lines, just like this :

                          # uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=2
#hdmi_mode=82

#hdmi_ignore_edid_audio=1

                          Be aware that you always turn on your TV or monitor before turning on the pi.
                          Not the other way around, as the pi might not recognize the TV or monitor.

                            That is a small problem. I have a cabinet and everything will is powered on at the sane time. I will try it out anyway :)

                              Powering the tv and pi at the same time will often give the same problem, not recognizing the TV or monitor properly.

                              Curious if it will improve after all recommendations.

                                unfortunatly that didnt help at all....

                                the log changed though, no more errors. but performance is as slow as before.

                                        @folly Yes we talked about that didn't we? This is a good plan

                                        I canceled my idea of making a new thread, at this moment.
                                        It seems there isn't that much amino for it, otherwise more people would have reacted on the idea.

                                        We can always do it in the future, when there is more desire.
                                        Agreed ?

                                            @folly I agree with Crush, I'd like to see a separate thread as well for the same reasons.
