Remember you will need enough cable to go from the back of the display to your port on the Mac. The Apple adapters are female, so if the port on the back of your monitor is also female (in other words has holes not spikes) you will need a male to female adapter. This cable doesnt need to be from Apple, but it will need to have the right connections. Sometimes youll find USB 3 or USB 3.1 port, which is the same port, but the predecessor to USB-C. USB-equipped displays are likely to be cheaper than Thunderbolt options, too. HDMI is the most common connector youll find on the back of a TV. There is also a long pin which may be surrounded by four other pins (which are required for audio in older models). You will see a marked difference when looking at HD video as compared to VGA. This conversion from digital to analog and back again can cause degradation of video quality. If you see a thunderbolt symbol besides what looks like a Mini DisplayPort, your Mac has a Thunderbolt port.Ī Thunderbolt-equipped Mac can connect a 4K Ultra HD TV via a direct HDMI connection, or via a Thunderbolt to high-speed HDMI adapter. HDMI ports are often found on TVs, making those Macs a popular choice for those setting up a media centre PC. With an adapter, the Mini DisplayPort can drive displays that feature VGA, DVI or HDMI interfaces. We look at how to use your iPad as a screen for your Mac here (along with which iPads and Macs support the feature).Ī white menu will be shown on the main screen (although since the launch of OS X Mavericks all screens can have a menu bar).Īpple has implemented quite a few different port types over the years, and your Mac desktop or MacBook might feature any of the following. On that note, if your display wont work with your Mac then the first thing to check is your adapter. There is one problem in particular that could stop your Mac working with an external display though: In the past Apple has made changes to macOS that have stopped some third-party adapters working with extra displays.įor example, when Apple introduced macOS Sierra in September 2016 many had issues getting a second display to work with certain adapters.
