Under certain circumstances, slides in your mmhmm presentation may appear blurry or may not appear at all. Learn why this may happen and how to make your slides display in the highest possible resolution.
Examples of blurry slides

If your audience is seeing blurry slides, follow the steps below to present your slides in the highest fidelity possible.
What causes blurry slides?
Video conferencing platforms optimize the quality of a call based on the bandwidth of its participants. When the platform detects a participant's low or unsteady bandwidth, it will sacrifice video fidelity to keep the call running smoothly.
Usually, this is fine—even if you're not seeing a teammate's talking head in the crispest resolution, you still get everything they're saying. Unfortunately, this bandwidth-saving tactic makes the slide unreadable because mmhmm uses the presenter's feed to transmit slide content.
Turn off background blur or virtual backgrounds
Some video conferencing platforms have the option to turn on background blur or virtual backgrounds which can interfere with mmhmm.
- Open Zoom and start or join a meeting.
- In the bottom toolbar, click the caret ^ icon next to Stop Video.
- If Blur My Background is checked, click it to deselect it.
This will disable the background blur and allow your mmhmm slides and background to be seen in full resolution.
If you have a virtual background applied in Zoom, your audience won't be able to see your mmhmm slides. To turn off virtual backgrounds in Zoom:
- Open Zoom and start or join a meeting.
- In the bottom toolbar, click the caret ^ icon next to Stop Video and select Choose Virtual Background.
- In the window that appears, select None.
This will disable your virtual background and allow your mmhmm slides and background to be seen.
- Open Google Meet and start or join a meeting.
-
In the bottom toolbar, click the More icon ⋮ and select Apply visual effects.
-
In the Effects sidebar, select the No effect option.
This will disable the background blur or other background effects and allow you and your audience to see your mmhmm slides and stage.
- Open Microsoft Teams and start or join a meeting.
-
In the top toolbar, click the More option and select Background effects.
-
In the Background settings sidebar, select the No effects option and click Apply.
This will disable the background blur or other background effects and allow your mmhmm slides and background to be seen in full resolution.
Turn off macOS camera effects
If you're on macOS and have a blurry background and have tried turning off background blur in your video conferencing tool, you might have macOS's Portrait mode enabled. This will apply a background blur on all of your video conferencing tools including mmhmm. To turn off portrait mode:
- Open mmhmm on your Mac.
- In the Mac menu bar, click the Video icon.
-
Click the mmhmm tab in the Video menu.
- Deselect Portrait.
This will disable the background blur and allow your mmhmm slides and background to be seen in full resolution. For more information about macOS camera effects, read Use macOS Sonoma camera effects in mmhmm.
Additional tips
- If you're sharing another application as a slide in mmhmm, make sure that the application is as large as your desktop without entering full screen and creating another desktop.
- We recommend 16:9 slides to be 1920 x 1080 pixels and 1:1 slides to be 2000 x 2000 pixels.
Picture quality will always be determined by the available bandwidth, but you'll be much less likely to encounter blurry slides by following these steps.
