RetroTINK 2x Pro & SCART Firmware Update v1.4

Mike Chi recently released a firmware update that applies to both of his current scalers/line doublers: the RetroTINK 2x Pro and 2x Scart.  Purchase all RetroTINK Products via multiple vendors worldwide here:  https://www.retrorgb.com/retrotink.html

This latest firmware introduces quite a few features and improvements:

  • Full EDID readout to detect DVI devices every time the video output port is cycled.
  • Added “Low Res YPbPr” plus scanline filter mode.
  • By popular request, added “sleep/off” mode. Press and hold the “Filter” button for 3 seconds to turn the device off. Short tap on the “Filter” button to turn the device back on.
  • Auto shut off of video output if no input is detected for 30 seconds. Red LED flashes 3 times to indicate video output power-down. Output is automatically resumed when a valid input is detected again.
  • Yet more tweaks to audio output in a futile attempt to maximize compatibility.

With firmware version 1.4, RetroTINK 2X Pro (and 2X Scart) users can finally power-cycle or set their device(s) to sleep mode through a simple button hold/press, without the need to unplug then plug back in the USB cable; a step that will significantly reduce the wear-and-tear on the on-board micro-USB port. Note that each of the subject devices uses its own unique .hex file, so be careful not to mix and match files while updating.
