Display port does not send signal to Iiyama Gmaster GB2788HS - Lenovo W541 - windows 8.1

Hello,

 

My machine, Lenovo W541 windows 8.1, suddenly stopped sending signals to my Iiyama Gmaster GB2788HS.

 

I was working with this setup yesterday and everything seemed fine. I've checked all of the cables but still the mini DP is not sending any signal. The device manager is showing no problems and there are no windows updates left on this machine

 

Can anyone help me out?

andere monitor geprobeerd? die gmaster op een andere pc aangesloten om de werking te checken?
