2 years ago It doesn't look like SA2 Mod Manager reports as a DPI aware application, so normally it should just look blurry. What you're seeing here is the result of a manual scaling mode override, most likely in SA2ModManager.exe properties. The SADX Mod Manager has explicit support for High DPI and the UI was designed around it, the same would need to be done for the SA2 Manager for it to look good at High DPI. Until then, all you can do is disable scaling mode override.

I recently upgraded to a 4K TV (not really by choice) and the SA2 Mod Loader has problems with high DPI scaling looking like as shown below. I have app scaling on Windows set to 200% since everything looks too tiny at the default scaling but for the mod loader of SA2 it causes this problem where as SA1's and Sonic R's Mod Loaders don't seem to have this problem.
