This is just a quick post reminding you that if you already own an RetroTINK 2x product, they all offer “passthrough” modes that send 240p through the HDMI port. That means if you’ve purchased an OSSC Pro, you can simply set your TINK to passthrough mode and essentially turn it into a composite and S-Video input board. This should work with the HDMI-only Morph as well, and will also work with the original OSSC, via an HDMI to component or VGA converter. More info and an example after the links:

Now, I’m not sure if I’d recommend buying a 2X Pro just for this feature, but if you already own one, absolutely give it a try – Maybe it’s all you’d need? While the OSSC Pro’s composite / S-Video expansion board will be cheaper, I’m not sure how it’s comb filter would compare. There’s no price confirmed for the Morph’s analog board, so who knows, maybe this is a cost-effective solution for that too?
One thing to note, is all RT2x products (except the ‘Multiformat’) only accept 15KHz signals, so this wouldn’t work with any 480p component video source. 15KHz component should work fine with the Morph, however both the OSSC and OSSC Pro have excellent handling of all YPbPr resolutions built right in. That said, HDMI-Only Morph users should be able to just use a cheap analog to digital converter for YPbPr (for consoles like the PS2, Xbox and Wii).
In case you’re curious, here’s a side-by-side comparison of an NES connected to the RT2x Pro in passthrough mode, into an OSSC Pro, versus the same NES connected to a RetroTINK 4K. Both scalers were set to output 1080p5x, however I cropped them to a 1440p window to make the comparison easier to see. While the RT4K’s comb filter is definitely better, the RT2x / OSSC combo holds up nicely!
