Make sure your PC (or phone), the external display, and the cable all support DisplayPort or MHL alternate modes. If you have a USB-C analog audio adapter connected to your PC, unplug it, then connect a USB-C digital audio adapter instead. See things on a bigger screen by connecting one of the Surface USB-C to display adapters to an external monitor or TV. Here’s what you’ll need: Make sure the device or dongle is connected to the USB-C port on your PC (or phone) that supports the correct Alternate Mode. For example, a DisplayPort Alternate Mode adapter should be connected to the USB-C port on your PC (or phone) that supports DisplayPort Alternate Mode.
Make sure the video cable is securely plugged into your external display or TV. On the other end, make sure the video cable is securely plugged into the adapter. DisplayPort (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K Take the video cable that’s connected to your external display or TV, and then plug the other end of it into the adapter.Make sure the device or dongle is connected to the USB-C port on your PC that supports the correct Alternate Mode. For example, a DisplayPort Alternate Mode adapter should be connected to the USB-C port on your PC that supports DisplayPort Alternate Mode. The device or dongle you connected to has new features for USB-C that your PC (or phone) doesn’t support. READ NEXT: What’s the difference between WQHD, QHD, 2K, 4K and UHD? DisplayPort: 4K at 144Hz with audio and video capabilities
The device or dongle you connected to has new features for USB-C that your PC (or phone) doesn’t support. A newer 1.3 and 1.4 version, that both have a maximum data rate of 25.92 Gbits/sec, are both becoming more widely available. With the increased bandwidth capabilities, it opens up the floodgates to higher resolutions such as 7,680 x 4,320 (8K). Dust or dirt inside the USB port on your device might be preventing the charger from being inserted correctly.The HDMI Alternate Mode lets you project video and play audio on an external display that supports HDMI. To charge faster, your PC (or phone), charger, and cable must all support the industry standards. Your charger and cable must also support the power levels your PC (or phone) 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. 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.
Unplug the video cable from your display, and then unplug the other end of the cable from the adapter. Select the Start button, then type device manager and select Device Manager from the list of results. HDR can be described as the ratio between the lightest and darkest parts of an image. Typically, with standard dynamic range, you’re losing detail at either end of the light spectrum. Expose a scene for the shadow detail and you end up with blown-out highlights or expose for the highlights and you lose shadow detail. HDR allows a greater range of detail across the full light spectrum.To get 144Hz, you should ideally use DisplayPort as it’s the most capable out of the bunch. Here, DisplayPort 1.0-1.1a is able to output 144Hz at 1080p, while 1.2-1.2a can output 1440p at 144Hz, 1.3 outputs up to 120Hz at 4K, and 1.4 can output 144Hz at 4K using Display Stream Compression (DSC). It’s the best connection to display 144Hz. DVI stands for “Digital Visual Interface”, and is another common connection found on PC monitors. Things can become a little confusing when you consider there are three different types of DVI. There’s DVI-A (analog signal), DVI-D (digital signal) and DVI-I (integrated analog and digital signal). Not only that, but DVI-D and DVI-I have single-link and dual-link versions. Nowadays, DVI-A is very uncommon, as it’s no better than VGA. The USB device that you connected to reported a problem, or there’s a problem with the device driver. We outline the different types of connections below and give you different usage scenarios to help you decide. We’ll also outline the best connection and cable to choose for 144Hz and other higher refresh rate displays.
Chargers that don't have a standard USB Type-C connector might use a proprietary, nonstandard connector that your PC doesn’t support. If your Windows 10 phone is already running the latest version of Windows 10 Mobile, try to connect your device to a Windows 10 PC instead. Make sure the device or dongle is connected to the USB-C port on your PC that supports the features of the device or dongle. For example, if you're connecting a Thunderbolt device, make sure it’s connected to the USB-C port on your PC that supports Thunderbolt.
We explain the difference between every display connection available and help you decide which is best for you
HDMI is unique among the many connection options in that it’s able to carry both uncompressed video and uncompressed audio. This is why it’s become the connection of choice for most multimedia devices as it’s a one-cable solution.
