![]() If possible, check to see if using a different display or a different adapter works. ![]() If your display has more than one video connection, see if using another connection on the display works.For example, a mini DisplayPort to DVI adapter can't be connected to a DVI to HDMI adapter. Some video adapters can't be connected together. If you're using more than one video adapter to connect your display (the adapters are 'chained' together), try connecting the display using only one adapter if possible.If you're using a video adapter, unplug the video adapter from your Mac, then plug it back in to reseat the connection.Disconnect the video cable where it plugs into your Mac, then plug it back in to reseat the connection.If you're using a display hub, switchbox, or 'KVM,' try connecting your display's video cable directly to your Mac instead.If you're using a Mac Pro (Late 2013) make sure your displays are connected to the right ports.Make sure the external display's power cable is securely connected and that your display is turned on. ![]()
