Hi guys, I need an extension cable for my 2009 Mac pro and 24" Cinema Display as right now the cable is far too short from tower to monitor. I'm based in the UK. Is this what I need? https://www.amazon.co.uk/Neet®-DisplayPort-Extension-female-Display-WHITE/dp/B002SLNQJG Also, do Apple do their version? I can't seem to find one anywhere.
