Issue with external monitor when connecting mini DisplayPort to DVI
Install any macOS or firmware updates that are listed. If the display image is blank or unusable Try these steps if you don't see an image on your display. Check connections Check the connections to your Mac and external displays: If you're using an Apple notebook, try connecting its power adapter.
Make sure the external display's power cable is securely connected and that your display is turned on. If you're using a Mac Pro Late make sure your displays are connected to the right ports. If you're using a display hub, switchbox, or "KVM," try connecting your display's video cable directly to your Mac instead. Disconnect the video cable where it plugs into your Mac, then plug it back in to reseat the connection.
If you're using a video adapter, unplug the video adapter from your Mac, then plug it back in to reseat the connection. 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. Some video adapters can't be connected together.
If your display has more than one video connection, see if using another connection on the display works. If possible, check to see if using a different display or a different adapter works. Try using a different cable that you know is in working order. Check with the display's manufacturer to make sure you're using the cable they recommend. Restart the Mac with the display connected. Wait a few moments, then press a key on your keyboard or click your mouse or trackpad to wake your Mac. Adjust video settings If there's no image on your display, try adjusting your display's brightness or contrast.
To adjust the brightness of a secondary display, press Control-F2. If you're using a display that's not made by Apple, check the documentation that came with your display to see if it includes built-in controls for adjusting its brightness or contrast. Click the Displays icon. Click Default for display. If you see more than one resolution listed, choose a resolution and refresh rate. If the display turns off when you change resolutions, press the escape key to undo the change. Check for third-party display software If your display works only when your Mac is started in safe mode, and you have display-related software installed, check with the software's developer for updates, or try temporarily uninstalling it.
I bought an Apple Thunderbolt to Thunderbolt cable. Nothing happens. Would a mini displayport to mini displayport cable work better? Sorry Pieere, I mistyped. It should work?

I would be really grateful if you can answer my question: I have three 27 inch apple cinema display model A, bought around at three locations which I connect my MacBook Pro mid model which I connect with the cinema screens everyday. I just bought a new MacBook Pro 13 inch three thunderbolts, 3 ports.
I even went to the apple store and they exchanged the adapter, however it still does not work. I called apple care and they said the older Cinema Display does not work with the new MacBook Pro with touch bar… I really need to know how I can keep using the Cinema Display which works perfectly. The people in the apple store said the display should work with the new MacBook Pro… I am wondering if I need to change to a different adaptor, like one from USBC to mini port… But I read that mini display port should with thunderbolt adaptor… Look forward to hear any inputs!

Hi Pierre, I have aa imac as well as a macbook pro and am just trying to connect and use the imac as a mirror screen from the macbook. I have tried to connect with a thunderbolt but it does not seem to work. Is there a difference if I use a Microport display cable instead of the thunderbolt? A Mini DisplayPort cable is just a cable.
Actually, witn a 27 inches iMac not the 21 inch and a Mini DP cable, it will work. I plan on buying some monitors to connect to my MacBook Pro. I have a few questions regarding my connection options. And then connect the first monitor to the second monitor using a cable with DisplayPort connectors on both ends?
And what cables or adapters would I need to buy to make the connection work? Assuming I have 2 extra monitors, would it be best to connect them using the HDMI ports on the monitors? Is it possible to use the mini Displayport of a macbook pro to serve as a fast usb3 connection to a usb3 hard drive? If so, is such an adaptor available male miniDisplayPort to usb3?
