Rather than being an all-purpose line doubler like the OSSC, RetroTINK 2X aims to be a highly affordable device that can function either as a basic transcoder or line doubler on its own, or as a device integrated into a more complex setup.

More information & discussion
RetroTINK 2X requires an external DC power supply. Since the unit uses a Mini USB connector as a DC power supply input, any powered USB port can be used to supply voltage. If your television has a USB port then this can usually be used to power the device. If you require a separate power supply unit for the device then a suitable power supply can be purchased from VideoGamePerfection.com or from any good electronics retailer.
Do not use a power supply rated for AC output, or a power supply rated higher than 5 volts DC, doing so can damage the RetroTINK 2X.
RetroTINK 2X has three AV inputs. The currently selected input can be selected by pressing the input switch, which is the bottom of the two push button switches on the left of the unit. The input signal can be 240/288p or 480/576i (NTSC/PAL).
Important - Ensure that only one powered input is connected at any one time. For example, if devices are connected to S-Video and composite inputs at the same time, only the device currently in use can be powered, the other device must be powered off.
The yellow RCA connector on the front of the unit on the right hand side accepts a standard composite video (CVBS) signal suppled by a single RCA cable. Both PAL and NTSC formats are supported.
A S-Video device outputting a separate luma and chroma signal can be connected to the S-video input using a standard S-video cable. Both PAL and NTSC formats are supported.
A standard YPBPR component video signal can be input using the 3 RCA connectors on the front of the unit. Both PAL and NTSC formats are supported. Only 15khz resolutions are supported, 480p (and higher) resolutions are not supported and will not work.
Not that it is NOT possible to input RGB video using all four RCA connectors at the same time.
Connect a standard stereo analogue audio signal to the two RCA connectors on the right of the unit. This audio will be digitised and output via HDMI with the currently active video input.
RetroTINK 2X has a single HDMI video output. The connector is a mini HDMI that outputs 480p/576p in line-doubled mode or input resolution in passthrough mode.
RetroTINK is controlled using the two pushbuttons on the left of the unit. A series of small LEDs indicate what mode the device is in.
By pressing the input switch (see the image above) the user can cycle through the active inputs. If the image appears black and white, it is likely that the wrong input is selected.
By pressing the mode switch (labelled "smoothing On/Off" in the image above) the user can cycle through the three output modes. These are discussed in more detail in the next section.
RetroTINK 2X has three different output modes.
Mode 1 – Transcoding Only (all LEDs off) – In this mode the RetroTINK will perform digitisation only. Whatever resolution is fed in will be output. Note that many HDMI televisions do not support 240p input via HDMI at all. This mode is useful for users who wish to use the RetroTINK 2X with a HDMI to VGA adapter to feed the signal into legacy analogue video equipment such as BVM monitors, or for chaining the RetroTINK 2X through another scaler such as the OSSC.
Mode 2 – Line Doubling (2x LED on) – In this mode, a 240p signal will be converted to a 480p signal. A 480i signal will also be converted to a 480p signal using a simple "bob" deinterlacing technique. Beware of using the RetroTINK 2X’s deinterlacer on sources that display static graphics or text for a long period of time. RetroTINKs deinterlacer produces a constant flickering effect, this can cause image retention/burn in to occur faster than normal.
Mode 3 – Doubling + Smoothing (both LEDs on) – In this mode the RetroTINK 2X will apply an image smoothing filter to the output. This filter can smooth some of the jagged edges that appear in classic video games console graphics output. Setting this option is entirely a matter of taste, there is no right or wrong setting.
The picture below shows an example of how the smoothing filter changes the image.
There are two banks of small status LEDs on the RetroTINK 2X. The bottom bank indicates the currently active input. The LEDs are labelled "YPbPr" (component video), "Y/C" (S-Video) and "CVBS" (composite video).
These LEDS will blink rapidly for a split second when the RetroTINK is first powered on. If they continue to blink rapidly this indicates an error. Check the source signal and power cycle the RetroTINK 2X.
The top bank of LEDs are labelled "2X" and "FIL". If all of these LEDs are extinguished, the RetroTINK 2X is in transcoding only mode. If the 2X LED is lit, the RetroTINK 2X is in line double mode and any valid signal fed into the unit will be line doubled. If the "FIL" light is lit, the smoothing filter will also be applied. Note that it is not possible to use the smoothing filter in transcoding only mode.
Compatibility and special configuration
RetroTINK 2X is not a complex device and indeed there aren't many settings which can be changed. If there are any special compatibility steps which need to be followed they will be documented here.
RetroTINK 2X and OSSC
There has been considerable interest in using the RetroTINK 2X with the OSSC. Since the OSSC does not support composite or S-Video natively, the RetroTINK 2X can be used as a transcoder to enable these types of signals on the OSSC.
In order to use the two devices in tandem, it is necessary to use a HDMI to VGA converter. Care must be taken when selecting a converter for this task, as many such converters do not support 15khz video.
Results from using the two devices in tandem are varied, and some users report picture judder. The root cause of this and a solution are still being investigated.
