Ehm, just to be sure (since it probably was unclear in the first post): The patch is a executeable/binary; you should be able run it with ./Experimental_Patch ;)
Still doesn't work? The problem is, I believe, a missing "=" sign; as soon as your ration equals exactly 1920:1080, it won't work; the uploaded patch is a updated version with the sign in place, so I hope that it should fix it :3
