      The verbose setting was to add more into to the log file, I didn't think it would change the video output. Says in the log that resolution is 1600x1200 - is that correct for your monitor ?
      Try to run RetroArch standalone, without any RetroPie configs, just to rule out any issue with the default configuration. Run

      HOME=/tmp/ra /opt/retropie/emulators/retroarch/bin/retroarch -v --menu

      and see if anything changes.

        thanks for replying, mitu.
        yes, that's the correct resolution. the build was 20.1" dell monitor that mod to fit into an arcade 1up cab.
        run the code, retroarch launch, but still black screen.

          Did you install the AMD driver for your card ? Did you try with the open source (radv) driver instead ?

                  That doesn't seem to work at all - but it looks like it's using the same GPU driver (proprietary AMD install).

                      If the vulkaninfo command is ok, then try switching the RetroArch's video driver from gl to vulkan in /opt/retropie/configs/all/retroarch.cfg. It should be the line with video_driver.
