The codes for Samsung (like many of the big TV brands) have not changed in decades [with Sony being the wild card recently apparently]. Only new features required codes that will not be in old databases.
But if you are using the TV as a monitor (like you should), then you only need ON, OFF, and Inputs. Which should be in the old database.

As for the MX980, if you have problems connecting with Win10, there are several threads here on things to try. I always avoided the 980's so I never had to deal with that.
