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
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?
