If possible, remove one of the adapters and avoid chaining them together. Avoid video adapter chainsĪpple notes that chaining two incompatible video adapters together to make your Mac compatible with one or multiple external displays can actually cause issues as an example, you cannot connect a Mini DisplayPort to DVI adapter to a DVI to HDMI adapter and expect a picture, as it simply won’t work. Make sure your display(s) are plugged into the correct port(s).

This doesn’t apply to most Macs, but the late 2013 Mac Pro can be relatively picky. A loose connection will keep a proper electrical connection from occurring and can cause issues with your external display. Re-seat your video connectionsĮliminate the possibility of a loose display connection by unplugging your display cables and plugging them back in properly. One of the things Apple recommends you try if you are using an Apple notebook, such as a MacBook, MacBook Air, or MacBook Pro, is to connect the power adapter to give it additional power. Some Apple notebooks don’t have enough juice to push the extra pixels of an external display. Check to make sure that the external displays plug hasn’t come loose or that it’s plugged in at all. Hey, things happen! If you live where earthquakes are common, or you have rambunctious kids running around all the time, plugs are destined to work their way out of their sockets. Check the power plug on the external display So check your external display’s brightness level by pressing Control + F2 on your keyboard.
This can happen with external displays too. Silly me, I just forgot to turn the brightness back up. I thought my MacBook Pro’s display was borked when I disconnected the cable because the display stayed black.

One time while watching a movie in my living room, I used my MacBook Pro as a video source to my HDTV, and I turned the brightness all the way down on my MacBook Pro to direct all attention to the TV. Is your brightness turned all the way down? You can go to the Apple tech specs page, select your Mac, and see the displays it supports.
The general rule of thumb is that most modern Macs manufactured after 2013 will support such a high resolution (but not all of them). After you’ve first turned the external display on (because no one ever forgets to do that), here are some things you can check: Is the display supported?įor many 4K and 5K displays, you need to be using a Mac with a graphics card powerful enough to push that many pixels. It can also mean that there is a power issue, that the brightness is too low, or something else. Whenever your external display shows a black or other solid color, it typically means there’s a problem with the signal to the display, but not always.
No picture – screen is black or another color With a gist of some of the things that could have gone wrong, do any of these sound familiar to you? If so, follow along as we talk about some potential fixes to these issues.
