ScreenBright doesn't recognize Displaylink monitor

[stevebass]

Based on one the articles here, I downloaded ScreenBright in order to, well, change the brightness on the DisplayLink monitor.

Unfortunately, ScreenBright recognizes only the two other non-DisplayLink monitors.

Any ideas?

DisplayLink displays dont use directX in the same way as a graphics card.

I'm not sure what that means.

That software is for displays that use the DDC/CI protocol via your graphics driver, DisplayLink doesnt it has it's own driver chip. On a lot of DisplayLink screens the brightness has to be adjusted via hardware buttons.
