Getting video to work through an HDMI connection

Hello! Users have asked this before but the answers have been completely unsatisfying:

When I plug my macbook air M1 into an external monitor (an LG television, in this case) using an HDMI connection, it works fine EXCEPT it cannot stream video from online. Youtube, Netflix, HBO, etc, do not work. The videos buffer weirdly, the sound becomes distorted, the videos jump around but ultimately do not play correctly.

Yes, the monitor works correctly otherwise. Yes, I have checked my display settings. Yes, the monitor works completely fine streaming video from a non-Apple laptop connected via HDMI.

Is there a workaround or setting that I can change? Or is this just an inherent problem with M1 or OS?

Thanks!
