Schizo Cinema Display

Using a Mid-2015 15" Retina MacBook Pro

27" LED Thunderbolt Cinema Display.

OS X El Capitan 10.11.6

Intel Iris Pro Graphics


The display randomly shuts off causing havoc with the devices plugged into it. It happens randomly but when it does happen it's persistent. I've heard it can be the following:


• Can't power USB devices attached (most are not bus-powered).

• MacBook cannot drive two displays at hi-res.

• Faulty thunderbolt cable


It does seem to work okay when when I use I bypass the buslt-in thunderbolt cable and use a direct thunderbolt cable but that means nothing else attached to the display works - which is unnaceptbale.


So bored of this issue now. Is there a definitive solution?
