The Retrotink 4K is shaping up to be the most advanced retro gaming upscaler ever created

Mike Chi, the creator of the excellent Retrotink line of products, revealed that the upcoming Retrotink 4K will support pretty much every relevant video signal under the sun over its HD15 (VGA) port:

-RGBHV
-RGBS
-RGsB
-YPbPr
-Y/C (green/red)
-Composite (on both hsync and green)

HD15 is generally a more reliable option over SCART, the latter of which is prone to awkward cabling and bent pins.

On top of all this, he also revealed up to 1080p in for the RT4K. It's wild to think you could have a realistic use case with a system as modern as the Switch with this thing.
