SH4 is light years ahead of SH3 in that regard, and has all of the 'modern' resolutions because it apparently gets the list it uses from Windows. Someone else would have to mention the use of HDMI or other technologies with resolutions higher than 1920x1080, but if you set Windows to that, it will show in the game. The best thing to do is to set Windows to your monitors "native" resolution, which will show as "(recommended)" in the Windows dialog. Then set that in the game, and you should be good to go. If you by chance do not have a particular choice, then choose a multiple (divisible??) of it, such as 1920x1080 instead of 3840x2160, if that does not show in your game list. Just remember that after you activate the mod, you should delete the game's Save folder ("C:\Users \UserName \Documents \SH4" by default), and then re-set your video settings and other gameplay options.
