      Hi,

      I have an issue when using the OSSC with my Archimedes A440/1.  I have the OSSC connected to the Archimedes via a VGA to Scart cable, with the SCART going to the OSSC.  The OSSC is then connected to my monitor via HDMI.

      For the most part the OSSC works fine, and the monitor displays the computer output, however, and sadly not too infrequently, the screen will blank for a few seconds and then come back.  I am not sure why this is happening or what to do about it, is there a setting in the OSSC that I can try to change to prevent this?

      Thanks

      Craig

        The OSSC is v1.6 using 0.90a firmware

          Yeah – I had similar problems. I fixed it with a GBS-Control! 🙂

            So basically replace the unit with something else? 🙁

              Analog sync Vth setting is at least worth trying out. I’d also try direct VGA connection.
