This MST hub lets you connect three monitors to your DisplayPort™ (DP) 1.2 equipped Windows® laptop or desktop.

Increase productivity with multiple screens

The newest generations of computers are more portable than ever, which often means that you’re left with fewer video outputs and smaller integrated screens. This MST hub solves both of these problems by letting you connect three additional displays to your computer, which makes multitasking much easier. 

Increase Productivity with multiple screens

Connect to any display

With the MST hub, you can use DisplayPort video adapters and cable adapters that enable you to connect HDMI, VGA or DVI displays. This ensures your MST hub will be compatible with virtually any television, monitor or projector. This MST hub is VESA and DisplayPort certified to support DP 1.2 enabled systems, for seamless integration with your existing video equipment.

Extend Your Compatibility

Configure your displays for any environment

Using the MST hub, you can extend your desktop onto additional monitors and stream independent content to each display giving you the freedom to multitask and increase your productivity. You can also mirror the same image onto multiple displays for remote viewing applications such as digital signage.

Enjoy amazing video quality, without draining system resources

MST technology uses your existing video card to minimize the use of system resources while delivering Ultra HD 4K resolutions. This unprecedented performance makes MST perfect for high-resolution applications such as graphic design, gaming and medical imaging.

Note: When using a DisplayPort 1.1 video card the MSTDP123DP will act as splitter, automatically mirroring your video source across all displays. Resolution limitations apply.

The MSTDP123DP supports plug-and-play installation for a hassle-free setup, and is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Note: MST shares 21.6 Gbps across all attached displays. Higher resolutions can restrict the available bandwidth with the remaining ports, please see our guideline below for determining an ideal resolution for your setup. Certain graphics adapters have limited MST support and will only output to three displays in total. If more than three monitors are attached the fourth will be disabled.

Once it finally starts working, its good.

I bought this to run 3 monitors instead of my previous 2. I have my TV plugged in via a mini display port to hdmi cable. And my two monitors split via this hub on the display port output. It took me nearly two hours of tinkering and whatnot to get this working. It worked great once I did. However, next time I turned my computer on, my graphics card only showed my TV and one monitor. But then it blacked both displays and looked like it tried to bring up the other monitor. Then just went back to 2 displays. Repeat until I intervene or my system crashed. Long story short, my computer has crashed more times trying to display on all three monitors (8) than it has actually working with all three monitors (3).

Love the hub

Just set this up yesterday and am having the same issue as above. Not waking from sleep and requires power cycle on the hub. Other than that it works excellent. I hope to hear a solution soon.

Works largely as advertised with a few glitches. Driving this MST hub with NVIDIA Quadro K2200 and 3 HP monitors. Occasionally, monitors will not wake from sleep and I'm not sure if this is the MST hub or the K2200 causing this. A constantly reproducible behavior is that on machine boot, no monitor comes active during the BIOS startup and during the boot process, and I have to restart the MST hub to get Windows to display the logon screen. Seems to be an issue with the hub and system startup process.

Hello, Thank you for taking the time to review our MSTDP123DP hub. We are sorry to hear the unit is not operating as expected with your setup, and we would like to offer some assistance. If the monitors have multiple inputs (such as DisplayPort, DVI and HDMI), it may be best to set the monitors to the "DisplayPort" source specifically, rather than "Auto Select". This can be accomplished via your monitor’s On Screen Menu. Also, have you tried using the scan button on the MST Hub? Does it affect the functionality of the monitors when pressed? We have opened a support ticket with our Technical Advisory team under case number 303-215790; please reference that if you would like to contact us for further assistance. This hub is backed by our 2 year warranty, and includes free lifetime technical support. Hopefully we can help find a solution to this issue you are experiencing. Thank You, Customer Support StarTech.com http://www.startech.com/techsupport

the first hub i used just did not work, the second only allowed one monitor. all settings, cables and monitors were checked and in working order. hours of fiddling and the only thing I can find is the hub just does not work the way it should. windows detects the monitor but it remained blank and flashes out of range. Hz and resolution have been changed to every setting from high to low and nothing works. Not happy I have to return a $160 unit for the second time.
