    Great product , but not working as hoped

    Reviewed by - 8 juin 2023

    I will say, great product, clean design ... love the product ; however, my 3rd monitor will not connect. I have connected, reconnected, scanned, unplugged ... watched video after video ... maybe someone can help ... Computer = (1) DP port , I plug in (3) monitors , go to Windows 10 display settings ... monitor (1) works , monitor (2) is extended but the 3rd monitor , although on, can not be configured, hence it mirrors monitor (2) ... I can not extend displays 1,2,3 ... I have Main display 1 extended to 2,3 and this setup will not change ... regardless of what I do , change cables, unplug, reboot ... nothing. Please help, will include a picture. Thanks in advance

    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).

    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.

    Great for three (3) DisplayPort outputs!

    Reviewed by - 27 janvier 2019

    If you have a device that only has one (1) DisplayPort the 3-Port MST Hub works wonders to add an additional two (2) displays. In today's workspace two monitors are nice but three makes it better. The 3-Port MST hub is easy to use making it an inexpensive/easy upgrade to add additional display. I received this product in exchange for an unbiased review.

    Only works temporary

    Reviewed by - 25 mai 2023

    It was great to start with, then my monitor went to sleep. It took 2 months until I could get it started again and I even bought a new PC with extra memory. Then I got it going again, but alas, screen went to sleep. Havent been able to get it going ever since. My best advice, get something more reliable as they're not cheap.

    It does work- but not good at detecting monitors

    Reviewed by - 19 août 2021

    Every 5 or 6 wakes, a monitor is missing. normally the one your password box is on, so you fuss arround under the desk pressing the reset button (once if not twice). Sometimes your turning monitors off and on, pulling cables.. Sometimes you give up. Still using it after a few months, but not sure why.

    Works for a while but then doesn't

    For me, all three monitors worked flawlessly for a few months. Recently, my third monitor will not connect through the adapter at all. The monitor is not receiving a signal no matter how many times I power cycle or hit the scan button. Save your money.

    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.

    Must Have

    This is a great device. It was easy to install and is a must have for using Multi-Monitor from Display port.

    POSSIBLE solution

    Reviewed by - 18 avril 2023

    A POSSIBLE solution for multiple monitors, but not a slam dunk by any means. I have a Dell Optiplex 3070 SFF with Intel UHD Graphics 630 at DisplayPort rev 1.2. There is one DP port, one HDMI and one VGA on the integrated video card. The three monitors I wanted to use are all within a couple of years old, all have DP and HDMI inputs and one also has a DVI in. Initially I connected all three monitors to the MST using straight DP. Only one would respond on power up and wake from sleep. The other two would have to be power cycled repeatedly along with repeated pressing of the scan button on the MST. Once they finally responded, if the system was set to sleep the same nonsense with power cycling and re-scanning would have to occur on wake. StarTech FAQs just say to be sure the monitors are set to DP as they were. Failing that Startech recommends not allowing sleep mode - not a workable solution for me, and I still had the failure to respond on power up anyway. After two days of frustration and fiddling I have a passable solution by connecting the one responding DP monitor directly to DP from the MST, one connected to the MST by way of converting the DP to DVI, and one monitor connected to the computer HDMI port. They all respond on power up and wake up properly from sleep. But somehow I think the $150 would have been spent more wisely another way. My recommendation is to look elsewhere for a more reliable solution.
