I can attest that the Retrotink 2X mini works OK for connecting a Commodore 64 to a modern (HDMI) display. Though, there are some oddities... ideally, I'd like to just use it for the video signal, and let the audio go straight to speakers, but the video often gets messed up when I do that. The audio signal also becomes unusually strong. (Going through HDMI I can at least dampen it somewhat, although it seems to lose a good deal of bass) Probably some subtlety about voltages that I don't get about these ancient electronics.
