Here you see clearly the interferences in the green slider bar which are typically for composite signals.

The s-video signal doesn´t show the interference at all. This is one of the advantages of s-video compared to composite. But the colors are a bit blurry, the green bar seems to go through the slider. This is a result of the decreased color resolution of s-video compared to RGB.

The RGB signals shows the best and clearest colors. The text is sharp. The symbols on the buttons (rewind etc.) are better visible than with composite or s-video.
