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. 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. 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. This USB port doesn't support DisplayPort or Thunderbolt or MHL. Plug the USB device into a different USB port on your PC.
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.The HDMI Alternate Mode lets you project video and play audio on an external display that supports HDMI. The MHL Alternate Mode lets you project video and play audio on an external display that supports MHL. 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. Under most circumstances, you can get away with using whichever cable you have lying around – and whatever works – but if you have more specific needs, such as carrying audio, displaying a higher resolution or outputting a higher refresh rate for gaming, you’ll need to be more discerning with your choice of cable. USB Type-C has a new feature called Alternate Modes. If your USB-C cable has this feature, you can connect to non-USB devices that support the same Alternate Mode. For example, if your USB-C cable has the Thunderbolt Alternate Mode, you can connect to Thunderbolt devices. There's no setting to turn on—your device automatically uses the appropriate mode if it's supported.
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? 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. 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. 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.Note: This applies to all the error codes shown in Device Manager except error Code 28 (drivers for the device aren’t installed). Disconnect the adapter from your Surface, and then reconnect it. If that doesn’t work, disconnect the video cable from your adapter, and then reconnect it. 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. Make sure the USB-C connector on the adapter is securely plugged into the USB-C port on your Surface.
Your PC is providing power to other devices, so it has temporarily limited the power it provides to the device you just connected to. 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 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.
