If possible, remove one of the adapters and avoid chaining them together.As good as this sounds, sometimes problems can occur with external display that will require attention to get fixed.
In this piece, well go over various things that could go wrong with an external display, as well as some potential troubleshooting steps to fix the problem. What could possibly go wrong External displays, whether you bought one of Apples rather pricey options, or you went with a third-party brand like Dell, are subject to potential issues. Although Apple does its best to make things plug-and-play, other manufacturers tend to have very different standards, and this means you may have to troubleshoot issues or take extra steps to configure a display to work properly with your Mac. Even if your display isnt new, you may have nudged a configuration button by mistake, which could cause all kinds of issues with the its performance. If it wasnt you that tapped the button, and it happened while you werent even home because one of your kids was toying around, or someone else who used the computer changed the settings, then this makes it even more difficult to figure out whats going on. Among some of the things that can go wrong with an external display are: Blank or black picture gets displayed Blurry or wrongly-scaled picture is shown Inaccuracies and issues with color occur 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. No picture screen is black or another color Whenever your external display shows a black or other solid color, it typically means theres a problem with the signal to the display, but not always. It can also mean that there is a power issue, that the brightness is too low, or something else. After youve 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 For many 4K displays, you need to be using a Mac with a graphics card powerful enough to push that many pixels. The general rule of thumb is that most modern Macs manufactured after 2013 will support such a high resolution (but not all of them). Apple has an online support document that lists all of the Macs that are compatible with 4K displays. ![]() I thought my MacBook Pros display was borked when I disconnected the cable because the display stayed black. This can happen with external displays too, so check your external displays brightness level by pressing Control F2 on your keyboard. Check the power plug on the external display: 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 to make sure that the external displays plug hasnt come loose, or that its plugged in at all. Attach your Mac notebooks power adapter: Some Apple notebooks dont have enough juice to push the extra pixels of an external display. 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. Re-seat your video connections: Eliminate the possibility of a loose display connection by unplugging your display cables and plugging them back in properly. A loose connection will keep a proper electrical connection from occurring and can cause issues with your external display. Are you using the right port This doesnt apply to most Macs, but the late 2013 Mac Pro can be relatively picky. ![]() Avoid video adapter chains: Apple 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 wont work.
