Required ETS2 setup: Close the game, open Documents\Euro Truck Simulator 2\config.cfg, find uset r_multimon_mode and change it to uset r_multimon_mode "4". If the line is missing, add it. Save the file, then place the downloaded multimon_config.sii in the same Euro Truck Simulator 2 folder before starting the game.
