This Knowledge Base documentation covers common issues within classrooms supported by OIT Academic Support. There are 3 sections that have common issues as well as common troubleshooting steps for those issues.

Video issues

Q: What’s on my computer is not what’s being projected on my screen or The image looks distorted on the screen, but looks fine on my computer. 

A:  When first signing into the computer, OIT tells the computer to duplicate the screen and to select the correct resolution for the projector in the room. This is the default for podiums in our classrooms. There are times when the computers don’t do what we ask it to and needs to be done manually. Doing one or both of these things often solves the issue:

  1. Pressing the Windows key and the ‘P’ key at the same time on the keyboard will bring up the project sidebar. You want to hit duplicate on that screen.   
  2. Pressing the “Connect to Printers” icon on the desktop. This runs the commands we tell the computer to do initially when you first sign in.  

Q: The projector does not switch to the device that I want to present on the screen, automatically.  

A: Depending on the room, sometimes the room switches automatically and other times you have to select the device you want presented on the screen using a button panel or a remote.   

Columbine 1st and 2nd Floor: The podium PC will automatically connect once you turn on the projector. If plugging in a laptop, the picture will automatically switch to the laptop. If you would like to switch back to the podium PC, simply unplug the laptop.  

  1. If the initial set up doesn't work, the projector may be on the wrong input. To change inputs, please refer to the following pictures in determining what room you're in and what source you need to select. Those options are in green below:

University Hall A Wing: A small switching system is in place on the lectern. Option A(fully depressed) connects to the podium PC, while selecting Option B(unpressed), will connect to your laptop if you have it plugged in.  

Rooms with a touch or button panel: When the system is fully turned on, select the input you’d like projected on the screen.  

  1. If that doesn't work, try selecting another source on the screen. This can help determining if all sources are not working, or if a specific source is the cause of the issue.
    1. If another source is working, try switching back to the desired source and see if the picture is now working.
      1. If the above step doesn't work, please reach out to us so we can assist.

Extra troubleshooting: If for some reason these troubleshooting steps are still not working, there are other things you can try as sometimes, technology can get “stuck”.  

  1. Disconnect and reconnect the specific device you’d like to show on the screen  
  2. Select a different input then back to the preferred input if using a button or touch panel 

  3. If using an adapter, try the adapter on another device or try another adapter

    Note: Unfortunately, Academic Support does not check out adapters, devices, microphones, etc. If one is needed, please contact the FRC at [email protected].  

Sound Issues

Q: I’m not hearing anything through the speakers in the room.  

A: The first thing that we like to do when performing troubleshooting steps on audio issues is to open up a video with continuous audio. That way when one of the troubleshooting steps works, we can stop troubleshooting. One way this can be achieved is by opening up a Youtube stream(we prefer coffee shop tunes) and making sure all audio is not muted.

  1. Make sure that all audio players are unmuted. There are 3 potential areas to look for muted audio.  
    1. On the remote or button/touch panel 
    2. On the computer audio settings down in the bottom right hand corner 
    3. On the video playing the actual audio. 
  2. In classrooms with an Extron button panel, the amplifiers in that room “go to sleep” when no audio has been played for a while. Turn up the audio on the button panel and lower it to the desired volume level once audio starts playing.
  3. If in a Columbine 1st or 2nd floor room, make sure the projector is on. The projector must be turned on in these rooms for audio to play.
  4. On the computer audio settings in the bottom right hand corner, make sure the correct output device is selected from the drop down menu above the volume slider. This should be something like Realtek Speakers or Crestron Audio. If multiple devices are listed, check each one to see if sound plays, but do not select EasyIP Mixer. EasyIP Mixer should never be selected.
  5. Make sure that the 3.5mm cable or the audio cable is fully connected to the back of the computer. 

HyFlex Issues

Q: The video that I want to use is not showing up in my call or How do I show *insert device here* to the remote students?  

A: Depending on the room and the specific software you’re using to conduct your course online, you want to select the correct camera in the video settings of the software. Essentially, clicking on profile picture, settings, devices, select camera from drop down 

Q: Students connected to a Microsoft meeting/call are unable to sufficiently hear what is being said in the classroom. 

 A: Check the audio settings in your specific software. There should be settings to individually set the speaker and microphone for the podium PC. Depending on the setup, the setting for each may need to be something different. For the most part speaker should be room speakers and microphone should be EasyIP Mixer or AV Bridge.  

Q: How do I share the not just the video, but the audio on my computer with the remote students?  

 A: When sharing your screen with your class, you need to make sure the box “Share Audio” is also selected.

Other

Q: The projection screen is stuck and won’t come down/go up.  

A: This is an issue with the physical projection screen. It needs to be fixed/repaired by facility services. They need to be contacted so they can fix it.  To contact Facility Services, please call 719-255-3313 or navigate to https://facsrvs.uccs.edu/work-request to submit a work request.

Q: Microsoft *insert software here* is not installed on the podium PC or not opening up.  

A: Please call 255-HELP(x4357) and select option 3 for Academic Support. We can walk you through the steps on installing that software.  

Q: I cannot sign into the computer.  

A: There are several root causes of not being able to sign into a podium computer:

  1. If it states that you’re entering a bad username/password,  
    1. This error means that you’re entering your username/password incorrectly. Delete both entries and make sure there are no accidental spaces before/after your username. It’s also possible your password has expired and you need to change it.  
  2. “The trust relationship between this workstation and the primary domain failed”.  
    1. This error means that there is no network connection for the computer. Please plug in the network cable or ensure it’s properly in the computer all the way.
