StarTech.com Dual-Monitor DisplayPort 1.2 Splitter, DP to 2x DP Multi-Monitor Adapter, 4K 30Hz/1080p 60Hz MST Hub for Windows

Loved the idea behind this and what it brought to the table after I had already bought two monitors with displayport/VGA inputs only and a new desktop computer with one displayport output. I was able to connect both my monitors. This is a "dumb" device and my desktop didn't deal with it well sometimes switching one of my monitors resolution to 640x480. After my desktop went to sleep during the night I found I needed to unplug this and plug it back it so I'd have monitors.StarTech's technical staff was amazing at helping me and I wound up buying another adapter for HDMI to displayport and everything is working as I expect.Ask that being said I liked the product and the idea behind it. My Dell desktop just didn't play well. I have this device in its box, need one?

Setup was a snap. Works very well.

I switched out computers the old one had three displayports. The new one only has two. So I bought this splitter to run all three monitors follow the instructions exactly. Shut down the computer unplug the power cord install the splitter, hug the two display ports chords into the splitter. booted backup. It does not work! All three monitors have images on them, but the two monitors plugged into the splitter only shows one display. Display settings does not show all three monitors, just two. I'm returning this because it does not work

Worked like a charm. Two DP's plug in to it (and each monitor), it in to the single DP on your PC, they separate in to 1 and 2 monitor formats 1440 @ 60hz+. I wouldn't use a PC USB to power it so 3-4' USB type A extension will come in handy so it can reach a not-included USB power brick for power.Excellent. StarTech has been around a while, and always seems to have the useful gadgets. If they don't make a workaround piece of hardware, no one else probably does either. Good value.

I have been using this adapter for a year and a half now. I have a solid state drive with two Acer and one MSI monitors. All equipment is at least 6 years old. This is my workstation, and is turned on everyday. The two Acer monitors are connected to the adapter. The MSI is directly connected to the solid state drive.The adapter works well on a daily basis. Often one or both monitors in the adapter will not activate. If this happens, I disconnect and reconnect the adapter (not the monitors), and they light up again. Over the 18 months or so, I have had to reset the adapter 3 times. If you adapter just seems to stop working, I recommend a reset. It's always worked for me.To reset the adapter:1) Make sure your computer is on and the adapter is plugged in, as normal2) Unplug the adapter3) Unplug all attached devices to the adapter, including the power cord4) Plug the adapter into your computer5) Plug the power cord into your adapter6) Plug in the monitors to the adapterAt this point, the monitors might activate. Don't let this stop you from the final step.7) There is a little SCAN button on the front of the adapter beside the power cable plugin. Click the SCAN button. All monitors will flash and might go dark for a moment, but they reactivate soon enough.Hope this helps. It's been a great little adapter for me. If it did not require me to unplug/replug it so often, I would give it 5 stars.

UPDATE: I finally found a solution to the issues I was having. This MST hub has a limited amount of bandwidth for all connected monitors. Their website says that 1920x1080@60Hz = 22% of the bandwidth. I think 22% is actually 1920x1080@60Hz at 24bit color. Windows 8 and above only support 32bit color depths. The increased color depth results in a 33% increase in bandwidth to the MST hub, which means with 3x 1080p@60hz monitors connected it uses approximately 90% of the bandwidth. This should work but doesn't. The solution I found was to use the NVidia Control Panel to set the output color to 6 bits per channel (aka 24bit color). The 'Desktop color depth' can't be changed from 32bit, but 'Output color depth' can set to 6bpc. At 6bpc the bandwidth to the hub is reduced to a level that it can actually handle. I attached a picture for reference. I'm not sure if this is exclusive to NVidia cards, so I suggest you check your video card settings prior to purchasing this item.I'm raising the rating of this item back to 3 stars because it does actually drive 3 monitors at 1080p@60Hz.-2 stars for the poor documentation and frustration.---------------------UPDATE: I initially gave this product 3 stars, but after a month of using the device on a daily basis I'm downgrading it to 1 start. Over the past month I've run into the following issues. When I turn off my monitors at lunch or the end of the day, randomly I lose one monitor. Generally unplugging the MST Hub fixes it, but sometimes I have to power down everything for it to come back up. This is not a graphics card issue or monitor issue. I've tested with a cable connected directly to the laptop and have no issues. Today the same thing happened, but this time I couldn't get one of the monitors to come on. I pressed the scan button, power cycled, but nothing. I had to move the monitor to the unused port on the MST Hub. So in addition to all the other trouble, now I have a 3 port MST Hub with a dead port (yes I tried connecting other devices to the dead port and none of them get signal). This product is garbage. I highly suggest you look for another product, or plan to pull your hair out.---------------------I bought this for a 3 monitor configuration. My docking station has 2 DP ports, but with MST hubs can support up to 6 monitors. The video card in the laptop is an nVidia Quadro K1100m.I bought the 3 port hub in hopes of cleaning up some of the cable clutter on my desk. So the plan was to place the hub behind the 3 monitors and run a DP extension between the hub and the docking station. This didn't work out. The hub only supports 3x 1080p monitors at 24hz. This configuration had way too much flicker. I was able to run 2 monitors a 1080p@60hz and 1 at 800x600@60hz, but this is less than idea. It seems that the hub doesn't have enough bandwidth to support 3x 1080p@60hz. In the end I ran 2 monitors (1080p@60hz) off of the hub, and ran the third by connecting it directly to my docking stations 2nd DP port. I also tested this using the integrated Intel graphics card but got the same results. I also verified that the laptop/docking station is DisplayPort v1.2 compliant. The laptop is a HP ZBook 17 Gen1.I'm giving it 3 start because the manufactures website clearly says that 1920x1080 @60hz = 22% bandwidth, so 3 should only consume 66% meaning it should support this configuration. But unfortunately this is not the case. Other than this specific issue I find this to be a good product. If I were to purchase again I would probably try the 2 port version and save a few dollars.Manufacture's product page: [...]
