Stop working external display (thunderbolt and also USB-C) | x2 Elite 1013 G3

[X21013_user]

In April stopped working my external displays on Elite X2 1013 G3.

Elite x2 1013 G3 have 3 USB-C connectors (1x thunderbold, 2x usb-c supported displays).

I have 3 docks - HP Elite USB-C Docking Station G2 (connect 1 displayPort), HP USB-C Dock G5 (connect 2 displayPorts) and HP ENVY USB-C Hub (connect 1 HDMI), and switching it (home / work / presentation).

All these docks worked until April, and could be connected to Elite x2 1013 G3 via any of three USB-C connectors described above.

I tried everything - update windows, support assistant, uninstall graphic driver and instal from HP support, also instal from Intel, instal displayLink driver.

I know, that seems like bigger problem via computers (not only HP), because this problem is shown via forums, but without advices.

NOTE: All USB-C connectors recognize DOCK for USB devices (mouse, keyboard, ext. HDD), but no any display. Windows not detect more than internal display.

Windows 10 Pro 64bit, ver. 19042.928

product: 4QY52EA#ABB

TIP for interim solution:

F10 to BIOS, Advanced > System Options, check or uncheck "Enable High Resolution mode when connected to a USB-C DP alt mode dkc.

- it helps interim, it does not matter it checked or unchecked, you have to change it. After save, external monitors via dock works ONLY over one USB-C connector (only Thunderbold). After switch off PC, you have to enter to BIOS again and check/uncheck again, and after this ext. monitors works via thunderbold again.

- so doing it again and again till permanent solution will work.
