      I just got my Retrotink2x.

      I’m not getting a picture. I’ve noticed that the input LEDs flash rapidly when the supplied mini HDMI cable is plugged in. If I remove the cable and power cycle the lights no longer flicker. The lights flicker even when I have just the hdmi cable plugged into the Retrotink and not my display.
      To me it seems like a possible bad cable or could it be the Retrotink?

        Same thing here, but my RT2x works fine.
        Seems like the “Hot Plug” feature of the HDMI chip acting up, datasheet calls for a 10k resistor to ground which is absent from the RT2x.

        This should be in the manual:
        Always plug the HDMI cable before plugging the micro USB power cable.

          Thanks. I found the problem to actually be with my fast charger. I ran the power to my PC and it works just fine now.

            Ah yes, a phone charger is the worst way you can power the RT2x, plenty of ripple.
            A TV or a PC has LM7805 regulators for the 5v lines of the USB ports, so they are very clean in comparison to a phone charger.
            The previous post still applies, so make sure you connect the HDMI first only then the power.

              Yeah I didn’t realize that a charger for an 800+ dollar phone was such shit. Haha.

                Well, it’s not shit for what it is designed to do, a phone charger is designed to charge a phone battery nothing more.
                A video processor which relies on a clear power source for minimal picture noise and instabilities needs a ripple free clean power source from a well filtered noiseless 5V DC regulator.
