Product Information
The product is a DisplayPort (DP) MST (Multi-Stream Transport) hub that allows you to connect multiple displays to your computer. It supports DP 1.2 and is compatible with Windows 7-11 operating systems. The hub can work with both dedicated video cards and integrated (or onboard) Intel graphics, although the number of supported displays may be limited in the latter case.
Product Usage Instructions
-
Setting up Multiple Displays:
To ensure all of your displays work properly, make sure your video card supports MST and the required number of displays. Check the video bandwidth limits of DisplayPort 1.2 to avoid exceeding them.
Refer to the table in the image gallery for specific details. -
Troubleshooting Display Issues:
If the product was previously working with all displays but stopped, follow these steps:- Disconnect the hub from the PC.
- Remove the power cable and video cables.
- Wait for 10 seconds.
- Reconnect the power cable.
- Connect the product to the PC.
- Connect each DP cable to the hub one at a time.
- Use Display Settings to arrange the displays.
-
Troubleshooting Wake from Sleep Issues:
If your monitors are not displaying after waking your computer from sleep, try the following:- Sleep and hibernation may cause problems in Windows 7-10. Consider using sleep less frequently if you’re not using Windows 11, as it provides fixes for rearrangement issues.
- If the issue persists, try restarting your computer.
-
Using Lower Resolution on 4K 60Hz Displays:
It is not recommended to use a 4K 60Hz display at a lower resolution. Such displays may reserve the full bandwidth they need even when set to lower resolutions within the operating system.
This may prevent other displays connected to the MST hub from working. -
Using with Laptop Docking Station:
It is not recommended to use the product with a laptop docking station to add more displays. Instead, consider using USB video adapters like USB32DP4K or USB32HDES. -
Using the Product as a Video Splitter:
To set up the product as a video splitter, you can use the Intel, AMD, or Nvidia graphics software application for your GPU. Refer to the respective software documentation for detailed instructions.
