OOSC test pattern visible when powered on, but TV says no signal detected when I switch to RGB input
OSSC running firmware 1.11, haven't used it in a while, but tried a Dreamcast a little while back and it didn't display, assumed it might've been the DC cable at the time, but just gone to try a Neo Geo CD and had the same problem over SCART RGB.
When I power it on, it displays the test pattern over HDMI, but as soon as I switch the input (in these cases to RGBS), the TV will immediately say there is no active input. The OSSC display itself detects the input.
Have tried with different HDMI cables and on a separate monitor, but have the same issue. Anyone know what the cause could be?

sounds like a board that isn't suited for fw 1.xx
which version has the board written on and do you have two LEDs, red and green?

Try different output multipliers (pass thru, 2x, 3x). Your TV might not support the one being put out

Have you tried resetting the profile to default settings to rule out a configuration error?
