Dell S2425H - Mac M1 - Fast Forward Issue

I recently bought a Dell S2425H (23.8"/60.45 cm FHD IPS 100 Hz). It’s a pretty good display, and the speaker quality is also nice.

I connected it via the HDMI port. After a few days, I noticed a strange issue:

When I opened a YouTube video in Chrome, it got stuck. After closer observation, I realized the video was playing at tremendous speed, skipping straight to the end.

I tried the same in Safari, but the issue persisted. I also tested with Twitter videos, and they wouldn’t play at all.

Resolution

1. Use Built-in Speakers

  • Go to Settings > Sound > Output > Change to MacBook Air.
  • This resolved the issue, but the audio output comes from the MacBook instead of the monitor.

2. Use Monitor Speakers

  • Plug in the HDMI cable before starting the Mac, not after it has booted.
  • Then restart the Mac.
  • This worked for me.
