DisplayPort 1.4 转三重 DisplayPort 4K 60Hz HDR MST 适配器

Works at it should and as expected

I changed out to a new desktop computer and the only output for a monitor was a single DisplayPort 1.4 outlet. I wanted to use two monitors in extended mode, and this hub did the trick. I can't say anything about how it works in the long term, but right now it is working perfectly.

I needed something to connect 3 27" 1440p 144Hz monitors that I normally have connected directly to my desktop (2080ti graphics card) to a docking station for my work computer while I'm working from home. The 2080ti supports DisplayPort 1.4 while the docking station/laptop only supports 1.2 (HP Zbook 15 G2) so I wanted something that would work for both. This was the cheapest I could find that supports DP 1.4 and has 3+ ports and so far it's working great.Some caveats that I've found is there are some limitations for both computers. On the laptop I can do two monitors at 1440p @ 60Hz and the third at 1080p @ 60Hz. This is purely a limitation of the computer/docking station though because I can run all 3 at 1440p on the desktop. However on the desktop I can only run them up to 120Hz, and I can't run all of them that high. It seems I can run 1-2 at 100 or 120Hz and the third at 60Hz.I was also having some issues with screens flickering and green/red dots moving around the screens in dark areas, but that was only on the laptop. After blowing out the docking station a little and plugging the connector back in a few times it seems to be working fine. I also wasn't able to use a USB port on the docking station to power it, but using a USB port on the laptop itself, a charging brick, or a USB port on another computer worked without any issues. I suspect this is because of how the USB ports work on my docking station with a keyboard and mouse already connected.Even though I've only been using it for a week or so, I would highly recommend this hub over spending 2-3x as much on a new docking station with 3 DisplayPort connectors or buying a similar 3-port hub locally.

With everything going on I had started to work from home and was sent home with my work computer and one monitor. I decided to use that monitor in addition to my own - which was fine for the work computer but my home computer had one displayport output. I grabbed this hub (after making sure my video card could handle it) and within 10-15 minutes had a working dual monitor system on my home computer as well. It's been several weeks and no issues yet!

It works great! I have no problem with it. It uses a usb to mini-usb to power it on. So if it is not working for you, check to make sure its plugged in.
