For 55"-65" Samsung TVs. Press a button on the remote and the tv rotates to vertical, great for the frame TV to display portrait art. See a video of it in action:

This is brand new in box, came as a part of a promotion with a new TV but I don't have space to have my TV rotate. Retails for $499+tax
Model number VG-ARAB43WMT
The box says it fits 22 Frame and 22 Neo QLED, I think it can fit others but check their website.
