Produkt ID: MSTDP123HD
Denna MST-hubb låter dig ansluta tre HDMI®-skärmar till din DisplayPort™ (DP) 1.2-utrustade bärbara eller stationära dator med Windows®.
Den nyaste generationen av datorer är mer bärbara än någonsin, vilket ofta innebär att du får färre videoutgångar och mindre inbyggda skärmar. Denna MST-hubb löser båda problemen genom att låta dig ansluta tre extra skärmar till datorn, vilket gör det mycket enklare att multitaska.
Om du använder MST-hubben kan du utöka ditt skrivbord till extra skärmar och strömma oberoende innehåll till varje skärm. Du kan dessutom spegla samma bild till flera HDMI-TV-apparater eller -projektorer för fjärrvisning på till exempel digitala skyltar.
MST-teknik använder ditt befintliga videokort för att minimera användningen av systemets resurser och samtidigt ge Ultra HD 4K-upplösningar. Denna oöverträffade prestanda gör MST perfekt för högupplösta användningar, som till exempel grafisk design, spel och medicinsk bildbehandling.
Obs.: När du använder ett DisplayPort 1.1-videokort kommer MSTDP123HD att fungera som en splitter som automatiskt speglar videokällan till alla skärmarna. Upplösningsbegränsningar förekommer.
MSTDP123HD stöder plug-and-play för en problemfri installation och täcks av StarTech.coms 3-årsgaranti och gratis livstidsgaranti på teknisk support.
Obs.: MST delar 21,6 Gbps över alla anslutna skärmar. Högre upplösningar kan begränsa bandbredden på resterande portar. Se våra riktlinjer nedan för att hitta idealisk upplösning för din situation. Vissa grafikadaptrar har begränsat stöd för MST och kan endast sända till upp till totalt tre skärmar. Om fler än tre skärmar ansluts kommer den fjärde att avaktiveras. Vissa skärmar begränsar den tillgängliga upplösningen

Direktchatt (opens in new window)To set up a MST hub with your MST compatible system, complete the following:
You should be able to detect the monitors in the display properties of your operating system.
If you are not getting any additional displays, try the following:
When the monitors are detected in the display properties of your operating system, make sure that the resolutions that you are setting do not exceed the total data throughput of the DisplayPort host connection. You can verify the total data throughput (bandwidth) under the Product Overview tab for you device.
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.
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:
To check to see if Windows is detecting the monitor, on a computer that is running a version of Windows 7, do the following:
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:
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:
Open Control Panel.
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.
Click Change plan settings for the plan in use.
For both entries, change Put the computer to sleep to Never.
Click Save Changes.
By default, most systems will duplicate to multiple displays when a MST hub is attached. If you are getting mirrored displays and cannot detect more than one display in Screen Resolution or Display Settings, your graphics card may not be compatible with MST. For more information about how to determine if your graphics card is MST compatible, refer to the following FAQ: https://www.startech.com/faq/mst-hubs-gpu-compatibility.
If you are using a version of Mac OSX, refer to the following FAQ for more information: https://www.startech.com/faq/mst-hubs-mac-osx-support.

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.
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.
Note: For information about Microsoft Surface tablets and MST, refer to the following FAQ: http://www.startech.com/faq/mst-hubs-microsoft-surface-tablet-compatibility.
Recent versions of DisplayPort include the ability to split to multiple displays from one DisplayPort connection using Multi-Stream Transport (MST).
Although you can connect the MST hub to any DisplayPort (DP) or Mini DisplayPort (mDP) connection, the graphics card in the computer must support MST to use a MST hub.
MST was added for DisplayPort 1.2 and includes support for High Bit Rate 2 (HBR2), which is required to operate MST. However, some manufacturers may not have implemented full support for MST.
If you are unsure if your computer supports MST, try the following:
Research the technical specifications of the DisplayPort sources for MST.
If no information is available for your product, contact the manufacturer for assistance.
Use USB video adapters found on StarTech.com as an alternative method to obtain multiple displays.
On a system with MST compatibility, multiple monitors are detected when they are connected to the hub. Multiple monitors can be used in the following configurations:
Extended: for separate, independent desktops/displays.
Spanned: a large, wide resolution that spans or spreads across multiple displays.
Duplicated: mirrored images on each display.
When a graphics card does not support MST, the hub will duplicate (mirror) the display across all three of the connections. Only one monitor will show in the displays configuration of your system.
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.
Although most Microsoft Surface tablets include Mini DisplayPort, the capabilities vary depending on the tablet model. For more information about MST hub compatibility, refer to the following table:
Model | Mini DisplayPort | MST | Graphics card |
Surface RT | No | No | NVIDIA Tegra 3 |
Surface Pro | Yes (DP 1.1) | No | Intel HD Graphics 4000 |
Surface 2 | No | No | NVIDIA Tegra 4 |
Surface Pro 2 | Yes (DP 1.2) | Yes | Intel HD Graphics 4400 |
Surface 3 | Yes (DP 1.1) | No | Intel HD Graphics (Cherry Trail) |
Surface Pro 3 | Yes (DP 1.2) | Yes |
Intel HD Graphics 4200 |
Surface Pro 4* | Yes (DP 1.2) | Yes |
Intel HD Graphics 515 |
Surface Book | Yes (DP 1.2) | Yes | Intel HD Graphics 520 |
*The Surface Pro 4 does not work with an MST hub when the Surface Pro 4 is connected to the Surface Dock. If the Surface Pro 4 is directly connected, it will work with an MST hub.
In order to access the full functionality of the hub, you need to install the latest drivers provided by Microsoft Update.
Note: 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, (as is the case with all of the Surface models listed above), your display limit will still be three displays even if you use an MST hub.
