      I am using a VGA splitter on a Midway 777 board-set to send the VGA video to an OSSC to be displayed via HDMI.

      With a REI VGA->HDMI Upscaler I am able to display the image on the screen but it is offset with no way to adjust (I am assuming due to some funky Midway output).

      When I connect the OSSC in a similar manner I get no output at all on the TV although the OSSC screen is detecting the following input:
      AV3: RGBHV 439p
      24.95kHz 56.84Hz

      If I attach an older VGA Dell LCD computer monitor the same way the display does work and after a couple auto display configuration (during the different boot/loading screens) if displays as it should.

      This is a Panasonic TV which displays my Sega NAOMI at 31kHz correctly.
      Any suggestions on settings to try?

      Having been able to fins a lot of other topics regarding med resolution troubleshooting.

      Thanks!

        You’re probably going to need a video processor that can accept a 56Hz refresh rate and do framerate conversion to get it up to 60. If your display is picky, like most 1080p TVs, 56Hz is way off-spec.

          Thanks for your response.
          I will try to connect the board to a Mini-Frameister and see if it comes up.
