Cursor stutter in video player on external tv

So I'm on sequoia m2 macbook air and i use hdmi(supports 4k 60hz) to connect it to my samsung 8(43)(which supports 4k 60hz). It was working fine until yesterday when i switched the hdmi port from 2(eARC) to 1 because sound ouput from tv was greyed out. Obviously didnt even work for HDMI 1 and then i switched back to hdmi 2 again. This time whenever i played a video, my cursor started stuttering(dropping frames to 24hz around) for 5 seconds every minute. I don't understand why, becuase the hdmi and laptop and tv all r capable of displaying 1080p 60hz(the resolution on which i work) on a 4k tv. Anything I'm missing? The sound output through tv on hdmi 2 is working now but the stutter problem has begun
