Yes fits. I use it with 65" model 2021 without problems

Hello TiRhon

In my search for the right cable, I have on the one hand the Samsung page
https://www.samsung.com/ch...
on the one hand, and on the other hand, I also contacted Samsung support via the e-mail address serviceb2b_ch@samsung.com.

I then ordered this cable for my Samsung TV The Frame 65". QE65LS03RAUXZG.

Also interesting to know.
At the time, I also asked about the Bluetooth connection at 15 m, as Bluetooth can have connection problems from a certain distance. The answer from Samsung was as follows:
"Since the Bluetooth sensor is installed in the frame and not in the One Connect Box, the cable length of 15m does not matter."

I hope this has helped you.

Thank you
