I have a 2014 Mac mini with a monitor connected via HDMI, that is going pink when waking up , I was told It's a on-board video problem, To solve this I was told to try and connect the monitor via a dock , I have connected a usb-c dock to the Mac via a usb-C to usb-A adapter , then a HDMI cable from monitor to the dock, when the monitor is connected the power light is on but the monitor isn't receiving a signal from the mac , and there is power to the dock because it has a blue light on it , I know the dock is Working because I have connected a usb mouse to it,
any help wold be greatly appreciated
thanks
