My previous post seems to have disappeared, so...
I have a new laptop (running dual nVidia GTX 580Ms) with an external monitor (Samsung S27A950D).
I bought a 1.8 metre cable and it works fine with the desktop extended across both displays.
With a 3 metre cable, however, I don't get anything through on the external monitor in any mode (extended, duplicated, or even with only the external monitor selected).
I have bought 2 different 3 metre cables from 2 different suppliers and the same thing happens, nothing output on the external.
Could it be the length of the cable? Cheap rubbishy cables?
Any thoughts would be appreciated.
