I've ran 3 monitors no issues for the last 6 months.
All of a sudden a few days ago, my 3rd monitor stopped working. and Windows stopped as well.

Ever since then, if I tell Windows to enable the 3rd monitor, it won't stop responding until I disconnect the cord.
I've tried another DP cable, same issue. I tested the offending monitor on my laptop and it works fine.

Could my graphics card have an issue with 3 monitors now or would this be a Windows issue possibly, since I've eliminated the cord and the monitor from the equation as both work on my laptop ?
