        have you read through this https://www.raspberrypi.org/documentation/configuration/config-txt/video.md

        Which values are valid for my monitor?
        Your HDMI monitor may only support a limited set of formats. To find out which formats are supported, use the following method:

        Set the output format to VGA 60Hz (hdmi_group=1 and hdmi_mode=1) and boot up your Raspberry Pi
        Enter the following command to give a list of CEA-supported modes: /opt/vc/bin/tvservice -m CEA
        Enter the following command to give a list of DMT-supported modes: /opt/vc/bin/tvservice -m DMT
        Enter the following command to show your current state: /opt/vc/bin/tvservice -s
        Enter the following commands to dump more detailed information from your monitor: /opt/vc/bin/tvservice -d edid.dat; /opt/vc/bin/edidparser edid.dat

          Hello @mark1986, thanks for trying to help I got this:

          pi@retropie:~ $ /opt/vc/bin/tvservice -m CEA
          Group CEA has 2 modes:
                     mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
                     mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
          
          pi@retropie:~ $ /opt/vc/bin/tvservice -m DMT
          Group DMT has 1 modes:
            (prefer) mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
          
          pi@retropie:~ $ /opt/vc/bin/tvservice -s
          state 0x12000a [HDMI DMT (4) RGB full 4:3], 640x480 @ 60.00Hz, progressive
          
          pi@retropie:~ $ /opt/vc/bin/tvservice -d edid.dat;/opt/vc/bin/edidparser edid.dat
          Nothing written!
          Enabling fuzzy format match...
          Failed to open edid.dat
          edid_parser exited with code -1
          

          I will try to understand and correct the problem with your link, but if you have any solution, I'm all ears!

              @malixx If it takes you this much time, isn't it easier to start with a fresh image and copy some of your old configs and roms to your new image?
              Also always good practise to backup your image often so you won't have to deal with stuff like this.

              I'm not tech savvy so all I can think of is this:
              Have you tried both turning the tv on before turning the Pi on and turning the tv on a minute after turning the Pi on? This makes a difference in how the Pi boots up. If your tv is already on then it uses that resolution. If your tv is not on (and hdmi video is forced) then it will use a low resolution.

              And have you used your hdmi port with another device to rule out your tv causing the issue?

                @bobharris Thanks for the reply, I have another SD Card with a fresh install and it does the same thing.

                I also tried both turning the tv on and off!

                I tried with different ports and also different cables... same result :(

                  Might be a hardware problem with your Pi then..

                      Ok just to be clear, the malfunction was because of my NESPI Case from Retroflag (I have the older version) maybe it drains too much power! Sorry I should have told you about the case, I thought it won't be the problem because it worked on another TV...
