Hi Pavel, UPDATE: After rebooting my machine and restarting the VM it all of a sudden supported the resolution and uses now the native 5120 x 1440 DQHD resolution on my screen!! So for Linux it is still needed to reboot te system for changes like that. I was not aware of that. any way, your tip for changing the vgamem but not the other parameters really worked! many thanks for your assistance! kind regards,
