Have a MacBook Pro M1 2020 with only Thunderbolt 3 ports. I have connected the Samsung and the picture is transmitted flawlessly. Only when playing music or YouTube is the sound choppy. Strangely enough, the video is also automatically fast-forwarded on YouTube. I contacted Samsung support and they told me to connect another device and test it. I will test it tomorrow with a Windows notebook. Have any of you had a similar problem?
