I'm trying to configure a 3 monitor setup for an operator console that sits 75 feet away from the manufacturing system it runs. I've run into this problem in the past and solved it with 3 boosted DVI cables, but this time around I'd like to find something less bulky if possible. PC would be running Windows 7 32bit, and would not be running anything graphically intense, just CNC control and monitoring software. Display Port 1.2's multistream looked promising, but doesn't seem to be able to extend that far from what I've been able to find.
I'm looking for how someone may have solved this previously, or suggestions on configurations to achieve my desired result.
