This is my first time with the opportunity to use a TB port/ cable and I'm overwhelmed by the terms and my options. My goal is to be able to plug in my macbook air and use target display mode with my 2013 imac. I'm not interested in wifi screen share or non-tethered options. Why do I keep seeing verbage for mini display port? Is that the headder on all thunderbolt cables? If I'm only using it as a display output (eg and not to a PCIe box) does it have to be a thunderbolt cable? Additionally would I be able to find a thunderbolt to hdmi for a non-thunderbolt monitor? belkin? apple? are there certifications I need to look for? someone on this site linked to this cable as one that works in my scenario, but the product description explicitly says "NOT compatible with iMac Display Mode or Thunderbolt Display" https://www.amazon.com/dp/B00HNF0L2C/?tag=stackoverfl08-20 thanks in advance for any advice.
