Check signal cable error message

[jholup]

Hello,
My Samsung monitor was working great as a third monitor using a Diamond BVU195 DisplayLink adapter, when all of a sudden it stopped working and says, "Check signal cable." The adapter appears to be working (green light on). Suggestions?

Try a different monitor in its spot. If that works then you have a bad monitor, if it doesn't you have a bad card.
