DisplayPort (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K If you want to combine the graphics outputs of your motherboard and your dedicated graphics card, this can be possible with certain Intel processors. This uses a “hybrid multi-monitor” mode but will be dependent on the chipset and possibly the motherboard used. You might also need to upgrade the BIOS to get it working. Intel lists the following chipsets as compatible in this hybrid mode: Hybrid multi-monitor support is officially supported with Intel Embedded Graphics Drivers for systems using the Intel Q45/G41/G45 and GM45/GL40/GS45 chipsets, or later. How to get 144Hz: Which cable is needed for 144Hz? DisplayPort 1-1.1a 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). Chargers that don't have a standard USB Type-C connector might use a proprietary, nonstandard connector that your PC (or phone) doesn’t support.

Choose HDMI 2 if DisplayPort isn’t available or if you require audio over 144Hz (as DVI doesn’t support audio) Make sure the USB-C connector on the adapter is securely plugged into the USB-C port on your Surface. More often than not, if you’re connecting something to a television, HDMI will be your best, and likely only, bet. Most PC monitors will also include an HDMI input. The good news, where it comes to 1.4 versus 2, is that you don’t need to rush out and buy new cables. To take advantage of the 2.0 specyou just need both devices on each end of the cable to be 2-compatible. Any HDMI cable will do, and we’ve already seen that there’s no difference in HDMI cable quality. You will likely find that your new Ultra HD/4K TV supports HDCP 2.2 on its HDMI port, but it’s not always for all of them. Some models will only support HDCP 2.2 for HDMI 1 and HDMI 2 inputs, so if you’re connecting a shiny new Ultra HD Blu-ray player, such as the Panasonic DMP-UB900 or Samsung UBD-K8500, make sure to use the correct HDMI input. 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).Until HDMI 2.0 became a standard, DisplayPort had it beat when it came to high resolutions. DisplayPort 1.2 has long been able to carry 3,840 x 2,160-resolution video at 60fps (or a refresh rate of 60Hz) and is the most common DisplayPort specification on most consumer monitors and devices now. This has 17.28Gbits/sec of bandwidth. 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.

Dust or dirt inside the USB port on your device might be preventing the charger from being inserted correctly. Make sure your PC (or phone), the external display, and the cable all support DisplayPort or MHL alternate modes. 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. HDMI has seen numerous revisions since its inception in 2002. Its most common version, used in most consumer devices at present, is 1.4 but there’s a newer, more exciting 2.0 specification now becoming more prominent. The main difference between the 1.4 and 2.0 specifications focus around bandwidth available. HDMI 1.4 has a bandwidth maximum of 10.2 Gbps/s whereas the HDMI 2.0 tops out at 18 Gbps/s.

We explain the difference between every display connection available and help you decide which is best for you

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. The USB device might have limited functionality when connected to this port. Plug the USB device into a different USB port on your PC.

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. Most monitors will have a range of different inputs available, and your PC or laptop will also use different outputs, so it can be difficult to decide which is the best connection to use.

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 (or phone) 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 (or phone) that supports Thunderbolt. 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 reason that bandwidth becomes important is due to the advent of 4K content. Due to the limited bandwidth of HDMI 1.4, only 24fps was possible at 4K resolution (3,840 x 2,160). Now, thanks to the extra bandwidth available in the 2.0spec, up to 60fps at 4K resolution is possible. This also allows you to view 144Hz at 1080p (1,920 x 1,080) through a HDMI 2.0 connection. Make sure the device or dongle is connected to the USB-C port on your PC that supports the correct Alternate Mode. For example, if you're connecting a Thunderbolt Alternate Mode device, make sure you connect to the USB-C port that supports Thunderbolt™. Unplug the video cable from your display, and then unplug the other end of the cable from the adapter. The USB device that you connected to reported a problem, or there’s a problem with the device driver. Chargers that don't have a standard USB Type-C connector might use a proprietary, nonstandard connector that your PC doesn’t support.Note: This applies to all the error codes shown in Device Manager except error Code 28 (drivers for the device aren’t installed). The device or dongle you connected to has new features for USB-C that your PC (or phone) doesn’t support.
