Yes, and those are my personal settings for 2560x1440 :
custom_viewport_width = “1792” custom_viewport_height = “1435” custom_viewport_x = “382” custom_viewport_y = “-20”
1792x1435 is not 4 : 3 aspect ratio according to online aspect ratio calculator, yet strangely it fits perfectly the screen (if someone has an explanation, I would be happy to know ! ).
