The secondary monitor only displays 1200 * 800

ZBook Firefly 15 G7 Mobile Workstation
Microsoft Windows 10 (64-bit)

Good day,
I have an HP ZBook Firefly 15 G7 Mobile Workstation notebook (Product Number: 111F5EA) and an HP USB-C Dock G5 (Product Number: 5TW10AA).
2 HP 27q monitors are connected to it via the display port.
The first monitor shows the native resolution of QHD (2,560 x 1,440) but unfortunately the second displays the resolution only 1200 * 800.
I can't set the correct setting to QHD (2,560 x 1,440) on the second monitor.
I updated the NTB firmware, docking station and all drivers to the current version.
Next, I tried to connect kinds of monitor using HDMI.
I tried both USB-C ports and no change.
The Windows 10 version is 1909
Where is the problem why it doesn't work on both monitors in QHD?

Dobrý večer, @PolakJ 

 

This is a known issue and in order to active high resolution, you need to make some settings changes. Please, adjust your BIOS/UEFI settings:

 

Enable High Resolution mode when connected to a USB-C DP alt mode dock option.
  1. Start or restart the computer and enter HP Computer Setup F10.

    note:
    This can be performed by pressing the F10 key while the computer is restarting.


  2. Select Advanced tab > System Options.
  3. Check Enable High Resolution mode when connected to a USB-C DP a lot mode dock.
  4. Make sure you do SAVE the changes before exiting the BIOS and restart
