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 by using the broadcast window.

If your audience is experiencing blurry slides, follow the steps below to present your slides in the highest fidelity possible. 

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.

Use the Broadcast window

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, click on the Broadcast button (Window > Broadcast). This will open an image of your Stage in a new window.

  2. Double click on the title bar of the Broadcast window to make it the same size as your desktop without going fullscreen.

  3. Click the "Share Screen" button in Zoom or "Present Now" in Google Meet.
  4. When given the option to share a screen or a window, select 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

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.
