- Pulsating, concentric rings that move left and right over another ring pattern (Robin destroyed it, later used on Beast Boy though they are stationary while pulsating)
- Moving and morphing diamonds (used on Starfire)
- Same as Robin's pattern, but moving up and down (used on Beast Boy )
As implied by the name, the screens put the viewer into a hypnotic trance, under which Mad Mod can control his victims. The effects may take some time to set in before it can fully control the victim. These conditions are apparent in "Mad Mod (episode)" where Robin and Starfire are able to repel the effects due to insufficient exposure time.
It is shown in "Revolution" that the trance can be broken when the hypnoscreens are removed or destroyed.
While the above conditions of hypnotizing and recovery usually works on the general public, in the exceptional case of Beast Boy, the effects of the hypnoscreens are triggered immediately upon looking at the screen, and he is only able to recover by making him laugh.
It only seemed to have a lasting effect in "Revolution", where after being freed from its initial effects, Beast Boy began speaking in a British accent and with British slang, while also praising many aspects of the British Empire. He was eventually freed from these effects, as well.

- All the hypnoscreens use some form of animated OP (optical) Art, which gained popularity in the 1960's
- Hidden hypnoscreens can be found throughout the comic "It's a Mod, Mod, Mod, Mod World" hinting at the plot reveal.
