Display problem, incorrect resolution

Display problem, incorrect resolution

After following the vanilla tutorial to install Mojave on my msi z390 gaming edge ac + i7 9700k, everything works fine except the display.

My screen is a LG 21/9 in 3440x1440 pixels, and the only resolution available in the monitor preferences is 1080p.

When I look in about my mac, the graphic card (intel 630) is not recognized.

Another strange thing, the only way for me to have something on the screen is to use my RTX 2070 nvidia card, when I plug my screen directly into my motherboard, nothing happens.

after a few hours of research and testing of different settings in clover I don't know where to look... any ideas?
