There are different ways:

1. Using resample

mpv -vo=gpu --video-sync=display-resample -hwdec=auto "https://www.youtube.com/watch?v=ENxwig2JOKo"

2. Use yt-dlp

mpv -ytdl-raw-options='format="mp4,best[height<1081]"' -vo=gpu --video-sync=display-resample "https://www.youtube.com/watch?v=ys5MqjzPTag"
