Question about Samsung The Frame QE32LS03C

Nothing works without the box. There is only 1 cable from the box to the frame, i.e. the power is also transmitted in it. The cable is relatively long, at least long enough for me to hide the box well.
Otherwise, I use the frame in a similar way to how you plan to use it, as a pure photo display, but not attached to a wall, but standing on its feet on a small table. I currently have a good 30 photos loaded onto the frame and randomly display a picture every 15 minutes.

Thank you. I bought one of these. But will sell it on...

In short, no, you need the box.
