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.

    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


Let me know how it goes. S pozdravom!
