When the user connect the USB-C cable from the display to the laptop, the resolution i wrong on both displays and/or one of the displays is black.

According to the product specification of your ThinkPad E431, doesn't include video output for the two USB 3.0 ports on the machine.
Should you want to use two external display at the same time, we recommend that you use a ThinkPad OneLink Dock can deliver video with no compression, no drivers and no impact on image quality and notebook performance.
