SLG360 Video Booster
A generic design known as the SLG360 is also available through various avenues such as eBay and AliExpress. This inexpensive adapter outputs both RGB and composite video with stereo audio through both RCA jacks and a 9-pin mini-DIN connector. However, it is not recommended as the RGB amplifier circuit is built incorrectly and the composite video output is not buffered or amplified. In addition, the stereo audio output is not amplified.
