I suspect I did not make myself clear enough. The Displayport and HDM are already in use and connected to a Workstation and a Surface Pro, so my only free ports are the Thunderbolt2 ports.According to LG's website https://www.lg.com/uk/monitors/lg-34UM95 that monitor does have Displayport and HDMI inputs as well. You should be able to then use an HDMI or Displayport cable. Post pictures of the inputs on it if you can.
