Using Two Computers Simultaneously to Teach in Zoom


While you can use two computers to teach on Zoom in a hybrid class setting, you will only be able to log in with your Denison account on one of the computers. Keep this in mind as you will need to be a guest on the other computer. Please see the instructions below.


  • Computer 1: This is your laptop. Open the Zoom Client (the application) and sign into your Denison Zoom account on this computer. 
  • Computer 2: This is the classroom podium computer. Do not sign into your Denison Zoom account on this computer. Join the Zoom as a “guest” from this computer by clicking on the meeting link and DO NOT sign in. You can make the guest account a co-host in order to share slides or documents onto the main screen during your class.


  1. On computer 1, sign into the Zoom Client (application) using your Denison account and start your class. Do not join with computer audio on this device because you will just use the microphone in the classroom. Close the pop-out window that prompts you to join computer audio. If you accidentally do join the audio, you can mute the microphone and mute the speakers on computer 1 after joining with computer audio.
    1. Note: If you are recording, Zoom might give you a pop-up message that says audio will not be recorded if you are muted. This is misleading. The other mics will be recorded, just not the muted microphone. The call audio will still record.
  2. On computer 2, click the class meeting link to launch zoom, but DO NOT sign in with your Denison Zoom account. Instead, you will join as a guest on computer 2. Use the classroom audio settings as indicated in the classroom guides.
    1. Note: If you do sign in with your Denison Zoom account, it is typically fine, but it will actually log you out on the first computer. This is just because you can only be logged in on one device at a time (source: Zoom help). Based on user testing, you can still continue to host the call even if you are technically logged out by signing in on another device but be aware of this.
  3. On computer 1, assign your guest account (the one on computer 2) to be a co-host in the meeting. Open the Participants panel, hover the cursor over the name of your guest account, then select More… > Make Co-Host.
  4. On one of your computers, you may wish to use the gallery view to see your remote students. Choosing this view on computer 2 will display remote students on the projector screen. Choosing this view on computer 1 will display remote students on your laptop screen. 
  5. You can use the share screen on either computer in the Zoom call to project slides, documents, or other resources to all remote and in the room students. You can also still share video and audio on computer 1 as long as you check the box next to “Share sound” in the bottom left corner of the share screen options window.
