Question Problems with USB 3.0 dual HDMI adapter with Windows 7


Recently I purchased i-tec USB 3.0 A/C dual HDMI adapter (U3DUAL4KHDMI) and I have a problem using it with Windows 7. I want to use 2 EIZO S1901 screen with adapter + ASUS connected directly to the PC.
My computer was not equipped originally with USB 3.0 so I purchased extension PCI-E card. Please see attachments (the back of my PC + how it is installed in W7). Drivers were updated. Nevertheless, I am getting a message about possible incompatible drivers (attached).

If I connect the HDMI adapter to the USB port (doesn't matter to which one, USB 3.0 or even to USB 2.0) the screens are mostly not visible by DisplayLink. Sometime it works and for few minutes screens are visible at DisplayLink. After this few minute bars are displayed on screens and it stops working - see attachement.

Please assist what can be done to use this adapter on my computer??

What happens if you would connect U3DUAL4KHDMI to a USB 2.0 port?

Would the behavior be the same?
