Not sure if you got a Manual so I added a link for you to Samsung's web page on the Monitor...link to Manual is near the bottom on the left...Section 3-1 is for setting up Optimal
Resolution. Section 4-1 is for setting up the Software and it does show Magic Tune.
There is a Trouble shooting guide in the same section as the Manual and there is a section for Magic Tune in the guide. Samsung BX2450
