Can anyone help find the right cable to connect my Surface 3 Pro to my monitor? Surface3 Pro appears to be mini display port. I'd like to connect to the full sized display port on my monitor.

I'm looking for something cheap from ebay or similar. I can find converters, mini display port to HDMI, "Thunderbolt Mini Display Port DP to DisplayPort DP 1.2 Cable" (which doesn't seem quite right for a surface) and a myriad of other things but not a mini display port to display port cable. I'm also slightly confused as cables that otherwise look right have "Thunderbolt" in the title.

Little help?
