Move what's on the screen across your Surface display and onto the TV or monitor screen. When you have displays extended, you can drag and move items between the two screens and select a different resolution for your second screen (to learn more about screen resolutions, go to Solution 6).

Sometimes, a simple restart can resolve the issue. On your Surface, select Start > Power > Restart . If there's an update available, it might say Update and restart . Turn the TV or other display off and on, then try connecting them again. See the same things on both your Surface and on the external display (to learn more about display resolutions, go to Solution 7).Using a Mini DisplayPort to DisplayPort cable, connect the Mini DisplayPort on your Surface to the DisplayPort input on the first external display. If only one of your external displays has an output port, connect your Surface to that external display first. Connect the output port of the first external display to the DisplayPort input port of the other external display. If using an HDMI video cable, make sure it's rated version 2.0, or, if using DisplayPort cable, it's rated 1.2, and is no more than 6 feet (1.8 meters) long. Longer cables can affect video quality.

There is only one difference between DisplayPort and Mini DisplayPort: the Mini DisplayPort is smaller than the regular DisplayPort. And you’ll get all the same features like resolutions, refresh rate, bandwidth, and others, according to the DisplayPort Version. At that time, this model was in demand in Apple products. Features like forwarding error correction, display stream compression, and MST were also in the Mini DisplayPort. You can read the difference between Mini DP and standard DP. The first clue to a DisplayPort link failure will probably be your monitor switching to low resolution. This mainly affects AMD GPUs and usually occurs after waking your computer and monitor from sleep.Though Mini DisplayPort is the smaller version of the actual ones, they always stay in competition with the normal DisplayPort. Some of the features of the mini DisplayPort leave the user in astonishment. We have given a list of some of those features – When you use two external displays, you may be able to achieve a higher refresh or screen resolution on one display by lowering the refresh or screen resolution used on the other. Both the host device and the external display need to support the Thunderbolt™, DisplayPort, High Bit Rate (HBR) standards.
