A week or two ago, I posted to what I believe to be the same thread talking about how I had bought a MinIDisplayPort to VGA adapter and a fairly standard VGA cable (from RadioShack, not Apple) to try and run dual monitors on my iMac (All-in-one, circa mid-2011) and gaming PC laptop (circa mid-2012-13). Alas, it was to no avail. I got response on my last post, saying VGA is not the way to go. However, in that time, I found out that my iMac has a ThunderBolt port and not a MiniDisplayPort. I come here today to ask: Should I keep the VGA cable and get a VGA to ThunderBolt adapter, returning the MiniDisplayPort adapter? Should I buy a completely new adapter, e.g. VGA to Thunderbolt? Should I do something else it the entirety (namely?)? Thanks in advance. Best regards, Matty.
