Mac with Kensington SD4790P not working with DisplayLink

Hello,

Kensington SD4790P is a product using combination of technologies. It can drive up to 3 screens: 1x alt-mode + 2x DisplayLink. Observed behaviour suggests the only working monitor uses alt-mode standard.

Did you grant "screen recording permission" to DisplayLink Manager?
