uptabDisplayPort to Dual DisplayPort Adapter 8K Multi Monitor Splitter, Converter Multi-Stream Transport (MST) Hub, DP to 2X DP

This UPTab product is extremely well built. It's solid and fully functional -- the case is even covered in a protective plastic sheet to prevent any scratches during final assembly and shipping. There is only one area where I would make improvement: I would ask for in the package and that would be some instructions regarding the use of a powered USB connection. I use a very modern NVidia RTX graphics card, and it required the USB powered cable in order for it to work properly. I had to research online for that fact. That's inconvenient and initially caused my system to crash when I just put the monitor cables on by themselves. I didn't even see the small USB port on the back until the online instruction pointed it out. So there you have it. You have a great product at a great price. It just needs to come with an advisory on the use of the USB port. Thank you for all your hard work.

Works

I have 3 monitors and a VR (1 Display port input required) just for reference of why I needed it with 3 DP inputs available on my GPU.I had issues when using the HDMI port along with 2 DPs such as my screen shutting off (HDMI screen only) so I decided to get a DP splitter around Black Friday and didn't have many issues at first. I expected something eventually since I had these 2 monitors displaying 2k @ 144Hz which is just slightly above the max limit of bandwidth for DP version 1.2, which Is the version this splitter has.The first week I had it, it was superb. No problems at all. The second week, I started noticing small chunks of my screen going static (as shown in the images) for a split second. This was on an EVGA 2080 Super FTW3. Issues persisted but it was outside of my return window.Upgraded to an MSI 3060 Ti Ventus 2x and it was still the same. Stopped using the PC for a little over a month since I had to renovate my room due to water leaking a few inches away from my monitors (TV took the hit and protected the monitors from any water damage) and now it's worse. I know this wasn't water damaged at all since the PC is far from the location of the leak.Both monitors now shut off a few times each day. The static now appears multiple times each minute. Sometimes it's small and a 1"x1" square, other times it's the whole screen. I would add more images but it stops doing it frequently the moment I start to record, or the problem ends up occurring on the monitor I'm not recording.To attempt to solve this, I dropped the 2 monitors on the splitter down to 2k @ 60 Hz. Having 2 monitors on 2k @ 60 Hz shouldn't be an issue, especially since the first week of owning the splitter, no issues were encounted. I just use these screens for multitasking or for browsing when a game is open on my main monitor,, but even when I am on my desktop and not moving anything in that screen region, I still encounter problems.The images I took were screenshots from a 60 FPS video on a Galaxy S20 and it was only 1-5 frames long. For the price of this item, this should not happen at all. I'd say take your money elsewhere and avoid this DP splitter.

I was able to split and extend to 2 monitors.

This is a completely useless waste of money. I originally purchased this device for my home office. After a few short months it stopped working. I contacted the manufacturer for a replacement and they had me try several steps. Nothing worked. They eventually sent a replacement. The replacement is even worse. It causes the screens to flicker on an off repeatedly. I asked them to replace again and they said it is impossible and must be my fault. But I I have tried everything they suggested and it still doesn’t work. I guess I am just out the money now.

Pro: The device works. It splits one Display Port output into two outputs. I did not need a driver. It was easy to plug and play.Con: The two screens blank for 1 second intervals randomly. Sometimes it is 10x per 5 minute interval, other times it is once per 5 minute interval. Screens to do not blank without device when tested. Screens blank when connected through device.Note: This device does not come with the USB power cable, you'll need your own.I tried 3 different, quality, display port cables.I tried 3 different USB power cords to power device.I tried 4 different USB power supplies to power the device with each cable.The device does get quite warm. I noticed when buried in the corner of the desk, it is very warm, and screen blanking is constant. When elevated in air, not near other devices, screen blanking is less often. However, this still occurs per above statement.I thought I could deal with the random screen blanking, however, after 3 days, I realized I cannot. I will return device.

This works. I've powered it by the USB cable to an always on USB port which helps with the connection, but my monitors still flash throughout the day which is annoying and there is a lot of noise on the screen (pixelation and green pixels). It works and is a temporary fix for me until I can get a graphics card with dual output. Not perfect.

For me its working perfectly with 2 monitors one is 4k 30hz and on 2k at 60hz both with good image and not errors at al.
