Microsoft 1661 Surface Dock

Product Information

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. When you connect your Surface to a TV or monitor, your Surface tries to set the best resolution based on the connector and the resolution of your TV or monitor. Using a Mini DisplayPort to DisplayPort cable, connect the Mini DisplayPort on your Surface to the DisplayPort input on the first monitor. If only one of your monitors has an output port, connect your Surface to that monitor first. Note: Common video input settings include VGA, DVI, AUX, DisplayPort, HDMI, Line in, Input, and Source. If your monitor supports DisplayPort, we recommend that you use a Mini DisplayPort-to-DisplayPort cable that’s no more than 6 feet (1.8 meters) long. DisplayPort will allow you to use the highest supported resolution and refresh rate with your Surface.

Both the host device and the external display need to support the Thunderbolt™, DisplayPort, High Bit Rate (HBR) standards. If you're using a video extension cable or video converter, remove it from your set up to see if it’s causing the problem. All Surface models can wirelessly connect to compatible displays using Miracast. To do this, press Windows logo key + P and select Connect to a wireless display. You can also wirelessly connect your Surface to an HDMI-compatible display by using the Microsoft Wireless Display Adapter.If the cable that came with your monitor isn’t responding, use a different video cable to connect your Surface. When you use two external displays, you may be able to achieve a higher refresh or display resolution on one display by lowering the refresh or display resolution used on the other. Solution 8: Try the adapter on a different external display Connect the output port of the first external display to the DisplayPort input port of the other external display.

Use this port to connect to your external monitor. Depending on your monitor's video output ports, you may need a display adapter (sold separately).

Follow the monitor manufacturer’s instructions to set both monitors to use DisplayPort 1.2 as an input source. For example, this might be called Multi-Stream Transport (MST), which allows the first monitor to pass the signal along to the second monitor. 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.

If you're using a video extension cable or video adapter or converter, remove it from your set up to see if it’s causing the problem. Use this port to connect to your external monitor. Depending on your monitor's connectors, you may need a display adapter (sold separately). 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.To see if your video adapter is working, connect your Surface to a different TV, monitor, or projector. If you can’t get what’s on your Surface display to show on a different external screen, you might need to replace the adapter. Solution 10: Consider these possibilities if your display is wireless Use the cable that came with your monitor or verify that the cable supports video. Always do this with Surface devices with USB-C ports. HDMI connections can also transmit audio signals. We also recommend you use Microsoft’s USB-C adapters on the devices equipped with the USB-C port. For more info, see Surface sound, volume, and audio accessories. When you need the reliability and speed of a wired network connection, connect your Surface to a wired network using the ethernet port.
