UPTab Mini DisplayPort to Dual HDMI 4K@60Hz Adapter Multi-Stream Transport (MST) Hub, DP to 2X HDMI 2.0

The product did not work in a normal way. I have been trying to use it for more than 4 months now, but every time I turn on my computer, the screen flickers repeatedly. It feels like I will go blind while I am using my two monitors. Now I saw that other people had this problem with this product. Well, now I am out of money and have to spend additional bucks while trying to find alternatives. PS: I also tried changing the USB cable which is used for power oping that may resolve the problem. But even after tying everything, the flickering problem remains.

I ordered a HDMI cable and I received it open and with out power cable..

Ok so this device works well. Certain with Windows you can create three extended screen no problem. Caveats. 1. It does come with (and needs) a USB power supply so be sure you have a USB port open for the power. 2. Along with that many computers come with at least one "Always-On" USB port. That works better because if your screens time out and the computer powers down the USB port the splitter it's plugged into, the HDMIs will disengage. My solution is to just put the computer to sleep if I'm not using it. Truly though the product does work reliably

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.

I needed this to hook up two monitors to a new computer with only one HDMI port. Worked like a charm!
