Your monitor shouldn't have anything to do with it. Frankly, I'm stumped.
Since all else has failed, the only thing I can suggest is taking the two folders inside the "Data" folder of the mod you want to use, and copy or move them to the "Data" folder of your SH4 install. Let it overwrite the existing folders and files when it asks. You will lose the stock versions of the files this way, unless you rename them first.
