21:9 wallpaper, Make me a hd wallpaper suitable for an ultrawide monitor. The left and right sides should be split in the middle and they should have different, yet complementary designs. The left side to be predominantly light gray in color and the right side should be predominantly dark gray. Add some professional looking yet creative touch to the design. The wallpaper should aim to balance eye comfort and cognitive function. The left side is where researching will be done, while the right side is where I'll be creating or typing down my work. | Fantasy
