USB-C naar HDMI multi-monitor splitter - 2-poorts MST Hub

When you troubleshoot issues with an MST hub, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

• Video cables

• Video source

• Video destination

• MST Hub

To test your setup components, try the following:

• Use the video cables, video source, video destination, and MST hub in another setup to see if the problem is with the components or the setup.

• Use a different video cable, video source, video destination, and MST hub in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

• Test each cable individually.

• Use short cables when you are testing.

• Eliminate the use of adapters, extenders, or splitters where possible.

When you test the MST hub with your computer system, do the following:

• Make sure that the computer/graphics adapter is MST compatible. For more information, refer to the following FAQ: http://www.startech.com/faq/mst-hubs-gpu-compatibility.

• Make sure that the latest graphics drivers are installed. The latest drivers are available on the website of the manufacturer of the graphics adapter.

• Use compatible adapters. For example, DisplayPort to HDMI and not HDMI to DisplayPort.

Note: Drivers are not required for the MST hub.

To check to see if Windows is detecting the monitor, on a computer that is running a version of Windows 8 or Windows 10, do the following:

1. On your keyboard, press the Windows key + X and click Control Panel.
2. Click Appearance and Personalization, then click Display.
3. In the left column, click Resolution or Adjust Resolution. Your monitors will be displayed as numbered icons.
4. To see which monitors are detected, click the Display menu.
5. To display the numbers on each of the connected monitors and see how the operating system has assigned their positions, click Identify.

To check to see if Windows is detecting the monitor, on a computer that is running a version of Windows 7, do the following:

1. Right-click on the desktop and click Screen Resolution.
2. To see which monitors are detected, click the Display menu.
3. In the left column, click Resolution or Adjust Resolution. Your monitors will be displayed as numbered icons.
4. To display the numbers on each of the connected monitors and see how the operating system has assigned their positions, click Identify.

If you are experiencing flickering issues with the MST hub, your monitors may be at a 59 Hz refresh rate. If they are at 59 Hz, you need to adjust the refresh rate to 60 Hz. In order to change your monitor's refresh rate, complete the following:

1. Right-click anywhere on your desktop.
2. Click Screen resolution or Display settings.
3. At the top of the screen, select the monitor that you want to change the refresh rate for.
4. Click Advanced settings or Display adapter properties.
5. On the Monitor tab, click the Screen refresh rate drop-down list.

Note: This step may vary depending on your operating system and graphics card.

If the displays connected to your MST hub do not wake up after your computer goes to sleep, change the input on the monitor(s) from Auto to the correct input (for example, DisplayPort or HDMI). This prompts the monitor to send its identification data to the correct port instead of scanning for ports when the signal is lost.

After you select the correct input on the monitor(s), press the Scan button to initiate the handshake (EDID) process. For more information on the Scan button, refer to the following FAQ: http://www.startech.com/faq/mst-hubs-scan-button.

If you set the monitor to the correct video port and press the Scan button and the issue is still not resolved, you need to disable sleep mode on your computer. To disable sleep on a computer running a version of Windows, complete the following:

1. Open Control Panel.

2. Click Power Options.

Note: Depending on how you have the View by options set in Control Panel, you might have to click Hardware and Sound to see Power Options.

3. Click Change plan settings for the plan in use.

4. For both entries, change Put the computer to sleep to Never.

5. Click Save Changes.

You may have heard of MST hubs, and have been wondering what they are, and whether or not they will work in your setup. 

So what are MST hubs?  MST hubs are devices that take one DisplayPort or Mini DisplayPort video connection, and go to many video connections, usually extra DisplayPort, Mini DisplayPort, DVI or HDMI connections.  This is accomplished through DisplayPort's MST, or Multi Stream Transport function.  MST hubs allow you to mirror / duplicate your monitors so the same window are shown on all of the monitors, or extend your desktop, so that you can have different window on each monitor.

So how can you tell if you can use a MST hub?  MST hubs require that the video card's DisplayPort or Mini DisplayPort output support DP1.2 or greater, which supports MST.  Some MST hubs also specifically require HBR2, or High Bit Rate 2 support.  HBR2 allows for higher resolutions like 4K and up.  You can check whether or not a StarTech.com MST hub requires HBR2 on the individual product pages, under the Technical Specifications tab.

There are a few other important things to note.

• Video cards can technically support DP1.2, but not support MST or HBR2, so it is important to check with your video card manufacturer that your video card specifically supports DP1.2, MST, and HBR2 (if necessary).

Currently Mac OSX does not support MST hubs, regardless of whether or not the video card does.  This is an operating system restriction, so running Windows on an Apple computer through a program like Bootcamp will allow you to use MST hubs.

Recent versions of DisplayPort include the ability to split to multiple displays from one DisplayPort connection using Multi-Stream Transport (MST).

Although you will be able to connect the MST hub to the Mini DisplayPort (mDP) connection on your Mac, Mac OSX does not support MST for NVIDIA and Intel Graphics Processor Units (GPUs). This results in a mirrored image across the outputs of a MST hub and you will not be able to have multiple independent displays on your Mac.

The limitation of NVIDIA and Intel GPUs lies within Mac OSX. If a different operating system is used, such as Microsoft Windows via Bootcamp, you may be able to use the MST functionality of your Mac.

You cannot use an MST hub to increase the maximum number of displays that a video card supports. For example, if your video card only supports up to three displays, your display limit will still be three displays even if you use an MST hub.

If you have multiple MST hubs connected to the same computer and are experiencing display issues, you should check your video card to make sure that it can support the number of displays that you are using in your setup.

If you use an MST hub in your setup, your video card also needs to be compatible with MST technology. For more information, refer to the following FAQ: https://www.startech.com/faq/mst-hubs-gpu-compatibility.

USB-C is a type of USB connector that is capable of supporting the following:

• Data transfer speeds up to 10Gbps, if you use USB 3.1.
• Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
• Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).

If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth. For more information, refer to the following FAQ: https://www.startech.com/faq/thunderbolt-3-port-capabilities.

Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require. For more information about whether your components support specific USB-C features, refer to the information provided by the manufacturers. 

This USB-C device requires that all of the following components support alternate modes:

• The USB-C host connection (for example, a computer and its port)
• The USB-C cable
• The USB-C device (for example, a hard drive docking station)

If your host device includes a Thunderbolt™ 3 connection, this USB-C device will work with your host device.

For more information about the modes that your setup components support, refer to the information provided by the manufacturers.
