It’s fairly normal that TVs will not support the same resolutions/frequencies over all inputs, and this is likely due to different inputs having different processing pipelines before hitting the screen.

For example, with my Samsung 32″ TV, circa 2009, composite, component, and HDMI likely all have their own processing pipelines, because the TV will accept 240p (and not deinterlace it) over component, but it will see it as 480i over composite, and it will outright refuse 240p over HDMI.

It sounds like the HDMI upscaler is resampling the image to be 60Hz, in which case you might begin to notice some periodic judder.

Probably should’ve searched first thing, but here’s a thread about OSSC settings for use with the MVS, and it looks like that links to yet another thread with further suggestions.
