Adjust your computer display settings

Adjusting the display settings of your computer can help reduce eye strain and fatigue.  Reducing the color temperature of your display lowers the amount of blue light emitted by a color display and may ofter better long-term viewing comfort.

There are many ways to do this and your operating system may have a  built in feature to change the color tempratue of your display to make it warmer.

Night Light (Windows 10)

Widows 10 has a built in feature called Night Light. If you turn on the night light and your display will show warmer colors at night. You can also schedule night light so it turns on automatically.

Night Shift (macOS)

Night Shift automatically shifts the colors of your display to the warmer end of the color spectrum after dark. You can create a custom Night Shift schedule or have Night Shift turn on automatically from sunset to sunrise or you can set the feature manualy.


f.lux: Your system may not have a feature to change the color temperature of your display so a program like f.lux can be very useful to achieve this function. It makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day. It also has additonal, more advanced features that you can explore.

Available for Mac, Linux, iPhone/iPad, Android

iPhone/iPad Screen Sharing with the Zoom Desktop Client

Zoom allows for iOS screen sharing from iPhone and iPad, using the Zoom desktop client. You can share wirelessly for both Mac and PC, utilizing iOS Screen Mirroring, or you can connect your iOS device to your Mac computer with a cable to share.

Note: A plug-in is required for this feature to work and Zoom may ask to install it if it's not already. If the plug-in fails to install you will need to do it manually. The link download the plug-in is provided on this page.

DIY Document Camera

If you have access to an iPhone or an iPad you can make it behave like a document camera for Zoom.  The process is simple but you will need to aquire a table stand to hold your iPhone or iPad face down towards the table.

Once you have a proper stand, follow the directions on this page, "iPhone/iPad Screen Sharing with the Zoom Desktop Client" then simply open that camera app. Since whatever is on your screen would be shared Zoom so will whatever is in front of the camera.

Note: you may have to adjust your iDevice settings so the screen doesn't turn itself off to safe power.
*This process will not work with an Android devices. A workaround to this would require 3rd party software.

Share Computer Sound

There are certain instances where you would want to share the sound that your computer generates in your Zoom session. For instance, you may want to play song or a video clip to your students.

Note: It is recommended to allow your students to watch videos or play audio on their own separately for better fidelity. However if that is preferred to play it on the Zoom meeting this is how you would do that.

When you are on the Share Screen selection dialog there are two options on the bottom of the dialog, "Share computer sound" and "Optimize Screen Share for Video Clip."

For video I would select both options. For audio only I would just check "Share computer sound."

This setting will transmit all of the sounds that your computer makes, which may include notification sounds.
