Although I'm referring to a MBP in this thread, I think this is a broader OS X El Capitan question... We're looking to buy a 4K LG webOS TV in the next few days and would like to connect an old 15" 2009 MacBook Pro to it on the odd occasion. The MacBook currently sits as part of our multimedia suite and we do use it now and then - I've put an SSD in it so it's great for basic stuff. I recognise the MBP cannot run 4K, nor do I want it to, but will I still be able to push 1080p or another scaled size? Or does OS X simply say "no" to any form of connection. I currently connect to our TV with an Apple Mini-DisplayPort to DVI adapter and a third-party DVI-male to HDMI-male cable. Thanks for any advice/pointers.
