The OSSC sees the output from the RetroTink 2X as 480i for both composite and component. Now I think the component 480i was because of the PS2 I was using to test. It didn’t matter though if the RetroTink 2X was in passthrough or 2X mode. Both of them were being received by the OSSC as 480i. I don’t know if this is because i didn’t turn off the OSSC when making the changes to the RT2X.
The OSSC was seeing S-video as 480p input in both 2X and passthough mode on the RT2X
