T480s with Docking Station flickering external monitors

My system configuration:

 

Machine type/model number:  20L8SAGW0A (ThinkPad 480s)

Docking Staion model number: 40AJ0135US (ThinkPad Ultra Docking Station)

Dual Acer 27" monitors model number: B276HUL

OS: Windows 10 Enterprise Version: 10.0.16299 (Build 16299)

BIOS Version: N22ET53W (1.30), 02/19/2019

BIOS Mode: UEFI

 

My firmware and software is current.

 

Using displayport connections cause a rapid flicker in all three devices (laptop, both Ace Monitors).  

 

Not even a single displayport connection works with these monitors.

 

The only connection that works is HDMI and is limited to one monitor with these docking station.

 

I used these monitors for more than 2 years with a T450 and different Lenovo docking station and had no problems.

 

Please advise on proposed solutions.

 

Thanks in advance.
