The max resolution I can use is 1200x800. At higher resoution I get an access violation error.
Tried to change the AN2 Data file. But it isn`t working with the mod, also.
The log.txt shows:

GFX Information
---------------
resolution : x:640 y:480 d:32 v:1 m:65535 t:0 a:0 w:0

whql signed : no (warning: the current graphic card driver is not whql certified!)

Is there a way to fix it that I can setup the resolution to UHD? Or WQHD?
The current driver is wqhl signed and the maximum resolution of the 2080TI Card is more than 4K.
