Why do my slides appear blurry to my audience when presenting on Zoom/Meet?

Under certain circumstances, slides can appear blurry. This article explains why it sometimes happens, and how you can present your slides in the highest fidelity possible.

Who is this for?

Most people don't experience blurry slides, but a workaround can be useful when you're presenting slides with smaller text and details. 

Why does it happen?

Video conferencing platforms optimize the quality of a call based on the bandwidth of its participants. As soon as the platform detects that a participant's bandwidth is low or unsteady, it will sacrifice video fidelity to keep the call running smoothly.

Usually, this is fine—even if you're not seeing a colleague's talking head in the crispest resolution, you still get everything they're saying. However, because mmhmm uses the presenter's feed to transmit slide content, this bandwidth-saving blurriness tactic renders the slide unreadable.

The workaround:

When a presenter begins sharing their screen, the platform will do everything it can to transmit that shared screen in crisp resolution. We've used this to our advantage by making it easier to share your mmhmm window. Here's how:

  1. In mmhmm, open the Broadcast window (Window > Broadcast), which will open an image of your Stage. Double click on the Title Bar that says Broadcast to make that screen the size of your desktop without going fullscreen.
  2. Click the "Share Screen" button in Zoom or "Present Now" in Google Meet
  3. When given the option to share a screen or a window, you want to share only the mmhmm -Broadcast window

This will automatically set your audience's screens to Speaker View and allow you to get maximized bandwidth for a smooth presentation.


Additional tips

  • Make sure that if you are sharing another application as a slide in mmhmm via Screens and devices > This Mac or iOS device, that the application is as large as your desktop without entering fullscreen and creating another desktop
  • We recommend for 16:9 slides to be 1920 x 1080p and 1:1 slides to be 2000p x 2000p

Picture quality will always be dictated by bandwidth, but with this process, you're much less likely to encounter blurriness. You can always still use screen share slides, but they will be much more likely to show up blurry.
