Dust or dirt inside the USB port on your device prevented the charger from being inserted correctly. In addition, we’d recommend choosing a new HDMI cable unless you’re confident that yours is fairly new. The HDMI specification has also changed over time, and older cables might not give you HD, or even 4K. For the best performance, look for HDMI 2.0 or HDMI 2.1, but anything over 1.4 should function. What happens when you want more than two displays? This will depend, once again, on your graphics card, your machine, and how much cash you’re putting aside to invest in this. It’s worth being aware that you might only be able to have one monitor, especially on older or lower spec machines, whereas you can connect up to four screens on more modern machines. Yes. Just like in standard DisplayPort connectors and cables, DisplayPort over USB-C can take advantage of the four high-speed data lanes in the USB-C connector and cable to provide 4K display resolutions and beyond on supported products. Notes: USB Type-C has a new feature called Alternate Modes which allows you to use non-USB connections with the USB-C cable and connection. There's no setting to turn on—your device automatically uses the appropriate mode if it's supported. Here are the display Alternate Modes that your cable may support:

The device or dongle you connected to has new features for USB-C that your PC (or phone) doesn’t support. USB-C has one specific disadvantage, and it’s the fact that many laptops have a limited number of USB-C ports. In that case, you may find you’ll need to get a USB-C hub to widen your options. Make sure it has a passthrough for the power supply, and ideally an extra USB-C port too. Many hubs also have an HDMI connection for added versatility. USB-C connectors that support the DisplayPort over USB-C will normally include the DisplayPort (DP) logo near the connector. Chargers that don't have a standard USB Type-C connector might use a proprietary, nonstandard connector that your PC doesn’t support.

Interfaces

An external display and video cable. The video cable and Surface adapter you need depends on which type of video port is on your external display. For example, if your external display has a DisplayPort, you will need a DisplayPort video cable and the Surface USB-C to DisplayPort adapter. Can I connect an existing monitor to a new computer, tablet or phone that uses the USB-C connector with DisplayPort over USB-C?

The USB device might have limited functionality when connected to this port. Plug the USB device into a different USB port on your PC. The Alternate Mode feature must be supported on the PC or phone's hardware and software, and the connected device or dongle. You might also need a specific USB-C cable.Hard drive retention: Hard drive retention is not available on models with a soldered hard drive, including XPS 9315 2in1, Chromebooks or Venue tablets, except the Venue 11 Pro.

There's a driver in the device you connected to that isn't supported in the version of Windows 10 Mobile your phone is running. For information about the supported devices, see Universal Serial Bus (USB). No video data will be received by the display, hence there will be no image on the screen. Doing this will not harm your device. A warning message might also be displayed on the screen of the USB product to notify the user about the incompatibility.

Bus Type

The device or dongle you connected to has new features for USB-C that your PC (or phone) doesn’t support. Yes. Adapters and Adapter cables are used to connect DisplayPort over USB-C to an HDMI/VGA input on the HDTV. If the HDTV has a DisplayPort input, then a USB-C to DisplayPort adapter cable can be used to provide DisplayPort display capability. The DisplayPort Alternate Mode lets you project video and play audio on an external display that supports DisplayPort. To charge faster, your PC, charger, and cable must all support the industry standards. Your charger and cable must also support the power levels your PC requires for the faster charging. For example, if your PC requires 12V and 3A for the fastest charging, a 5V, 3A charger won’t give you the fastest charging.

Make sure your PC (or phone), the external display, and the cable all support DisplayPort or MHL alternate modes. Make sure the USB-C connector on the adapter is securely plugged into the USB-C port on your Surface. How to connect a computer with USB-C port to an external display What do I need to connect my computer to an external display using the USB-C port?The Alternate Mode feature must be supported on the PC's hardware and software, and the connected device or dongle. You might also need a specific USB-C cable. Splitters are supported in DisplayPort connections, for example, which will allow you to use one port on the laptop to connect a number of monitors, although this isn’t a very economical way to do it since it might be a bit expensive. Unplug the video cable from your display, and then unplug the other end of the cable from the adapter. As technology continues to progress and new standards are created, it’s becoming more frequent to find difficulties in achieving the result you want. This also applies to monitors. The everyday, casual, user might not be familiar with USB-C, DisplayPort, or HDMI, and it’s not always clear for them. HDMI is the standard connection used by most televisions and monitors, and should be familiar to most people. Be aware, however, as there are variants. There are micro-HDMI and even mini-HDMI connectors, as well as the standard full size, so make sure you select the right cable.
