The best way to get a DP to HDMI adapter (4K/60) to work on a Mac/Hack is with an active adapter. That usually works with graphics cards but I'm not sure it will with Intel HD igfx. Most people use this https://www.amazon.com/dp/B00S0C7QO8/?tag=tonymacx86com-20I dont have a DP port in my philips tv. It is a 4k tv for sure, like I said on windows it works with that connector, but I can understand that macOS can refuse to work with a cheap things...heh, when I connect my tv to laptop, i have an option to change for 4K res, but then i get black screen and tv says "unsupported video format". I will get stupid now... on windows I can change it normally without any problems...what is going on...
