I have:
I am attempting to daisy chain the three monitors together to take advantage of multi-stream transport (MST). When I enable DisplayPort 1.2 mode on the first monitor in the chain, the second monitor gets its own desktop but the third monitor in the chain goes black and shows the standard "no input source". I also get this error message as a result of enabling 1.2 on the monitors. Anyone have experience with getting all 3 monitors to work correctly?

Things to check:
xrandr --verbose
will tell you what monitors the driver detected, what their preferred resolutions and refresh rates are.
