Resolution 3440x1440 on Intel UHD Graphics 630 does not work

[LHC3400-UWQHD-100-C]

Hey,

it is not possible on my Windows 10 System to select the above resolution -  I use the following Hardware:

Monitor: LHC3400-UWQHD-100-C

Graphic: intel UHD 630 (actual driver installed)

Connection HDMI 2.1 cable

The maximum resolution provided in Windows is 1920x1080. 

How do I realise the resolution 3440x1440?

Additionally, the intel graphics control panel does not start properly (several times deinstalled an reinstalled). The blue windows opens and thats it.....

Any ideas?

Yours, Marcus
