The Game / Data / Cfg folder holds the Main.cfg, which has the game's resolution, as the game first starts. Once you have been playing and the game has created a Save folder, then you will find that same info in the Save folder, generally "C:\Users \UserName \Documents \SH4 \ data \cfg \main.cfg". You can change the settings in there and "force" the game to that. However, you will have a "stretched" display, and the amount of the stretch depend upon how close you are to a pre-defined setting from the Graphic Settings in the game itself. If something in the game settings is close to what your screen is, you can use the "Windowed" mode of the game, and use the smaller resolution available in the game. If you are attempting something like a 4k resolution, you would most likely be better served with a divisible of the 4k resolution, such as a 1920x1080 setting in the game. The game was built for a 1024x768 resolution, so if you go much higher than that 1920x1080 resolution, your text size will suffer, or rather, your eyes will suffer from the tiny text.
