Device Settings – Best Practices

In many cases, your device will automatically use the correct audio and video settings when connected to our audio-visual Systems.

However there are times where you might have to change a setting or two on your device to make things work the way you want it to. This webpage features common fixes to issues with audio and video playback through our audio-visual systems.

If you have any questions or concerns, please contact the Help Desk via the phones on the side of the classroom podiums or using the contact information below:

Playing Zoom Audio Through Classroom Speakers

If you want to use Zoom in our classrooms to feature a guest speaker, it is not enough to change the general audio settings on your laptop. You will also have to change the sound settings in Zoom.

If you have your Zoom meeting open

First ensure that the (Program) volume on the Touch Panel is not set to the max. Recommend 30-40% for Program Speakers.

With your Zoom meeting open and live, move your cursor to the lower left hand corner of that window where the microphone icon is located. Click that little gray arrow as pictured below.

When you click that little gray arrow, you’ll get a large sub-menu. Navigate to the “Select a Speaker” section and click “DVX 2250.” Depending on the room you are in, it may be “DVX 3150” or “DVX 3250” or “Enova DVX 2250.” However that is expressed, select the option similar to that as pictured below:

Your guest speaker should be audible on the classroom speakers.

Another way to change the audio on Zoom

  1. First ensure that the (Program) volume on the Touch Panel is not set to the max. Recommend 30-40% for Program Speakers.
  2. With the Zoom app, click on icon with your initials on the upper right hand corner.
  3. A drop down menu will appear, click on “Settings.” Might be displayed as a Gear icon instead.
  4. A window should pop up resembling the screenshot below
  5. Click on “Audio” as indicated on the screenshot.
  6. Under Speaker, to the left of the “Test Speaker” button, click the drop down menu. You should see some options. Probably “Built-in speakers” and “same as system” and “DVX 2250.” Select “DVX 2250.”  If you are using the “Analog Laptop” connection, use “same as system.” Once the correct audio output is selected, the guest speaker should be audible on the classroom speakers.

Lecture Capture Warning!!! The Problem with HDCP

Some computers trigger HDCP when using lecture capture. HDCP stands for “High-Bandwidth Definition Content Protection,” and is a form of copyright enforcement.

So before you start your recording, always check the lecture capture preview window to make sure HDCP is not triggered. You will know this if you see a maroon rectangle where your slides/computer feed should be like in the example below:

Upper right hand corner of touch panel zoomed in showing HDCP being triggered by the Digital Laptop source.

If you see a maroon rectangle where your slides/computer feed should be, use the classroom phone on the side of the podium to notify us immediately!  We can usually resolve this very quickly if we are notified by the classroom phone. Unfortunately, HDCP incidences are very unpredictable and have to be reported to us in order to resolve it.

Livestreaming Issues for Remote Viewers

We usually receive complaints whenever students are using Google Chrome or Microsoft Edge to view classroom live streams. Those browsers at best produce choppy audio/video or most commonly provide a blank video with a buffering circle. Please instruct your remote learners to not use Google Chrome or Microsoft Edge. Firefox on either Windows or macOS works the best.

If students are using macOS or an iOS device, the Safari browser runs fine with that too.

Beyond that, we’re not able to help with connectivity issues in libraries, dorms, cafes and other environments beyond our control.

WINDOWS: Video adapters to avoid

If you need to use a video adapter with your PC in our classrooms, you generally have more flexibility than an Apple User. But there are two video adapters you should not use.  Avoid using a “hub” adapter that resembles the image below:

 

Due to the large number of ports, these kind of adapters do not pass audio and video signals properly in our AV Systems. They are good in an office setting, but are unreliable in a classroom.

Also, do not use a video adapter that plugs into a traditional USB Type-A port, pictured below:

These are never good enough to transport a video signal from your computer to the classroom projector.

Lastly, we recommend that you procure a simple video adapter that uses the classroom HDMI cord. In Fall 2023, our AV Systems will no longer have VGA(Analog Laptop) cables.

If you are unsure of what kind of adapter you need to purchase for your laptop, please contact the AV Help Desk.

WINDOWS: Mirroring your displays with your PC Laptop Keyboard

If you are connected to the AV System with your laptop, and what’s shown on the projection screen does not match what is showing on your computer like the image below:

Follow the process below:

  1. On your computer keyboard, simultaneously press the “Windows ” and “P” keys.

2. A menu on the right side of your computer display should pop up as pictured below. It will probably be on extended. Select “Duplicate” to match the projection screen with your laptop.

3. If the screens match, than you should be good to go!

WINDOWS: How to change the refresh rate on your PC Laptop

If you are connected to the AV System with your PC laptop, and what’s shown on the projection screen is either a black screen or the screen is showing an unpleasant, multi-colored, wavy signal across the projection screen like the image below:

 

  1. Select the “Start” button in the lower left hand corner of your PC Display. The “Start” button is the Microsoft Logo.
  2. Select “Settings.” May just look like a gear icon.
  3. New window will pop up, select “System.”
  4. Select “Display” or make sure it is selected.
  5. Scroll down a bit, and select “Advanced display settings.” There’s a lot of text, but it’s under the “Multiple displays” area of that menu.
  6. Under “Refresh rate”,  select the rate you want. Ideally, you’ll want to go from 60 Hz down to 30 Hz. The refresh rates that appear depend on your display and what it supports. Select laptops and external displays will support higher refresh rates.

WINDOWS 10: Audio Settings with USB-C

If your PC has a USB-C port, we strongly recommend that you use that to connect to the AV System. You will be able to send video, audio and charge your laptop simultaneously with one cord.

Settings for Apple Devices

This is an accordion element with a series of buttons that open and close related content panels.

APPLE: Please use an official Apple Adapter!

If your Apple Laptop has USB-C ports, we strongly recommend that you use the USB-C pullout cords to connect to the AV System. You will be able to send video, audio and charge your laptop simultaneously with one cord.

But if your Apple Device doesn’t have USB-C ports and you need to use a video adapter, please procure an official Apple Video Adapter.

Off-brand video adapters do not work consistently in our classrooms. Some of these off-brand adapter disrupt the signal from your MacBook, resulting in either a green tinted screen, glitchy screens or other weird video issues. And while many of those off-brand adapters will work properly in office or personal settings, or even in some other classrooms, we have found that well taken care of, OEM video adaptors from Apple produce far less weird AV issues with our systems. Alas, they’re the most expensive, but are the most reliable.

We recommend that you procure an official Apple adapter from the University Book Store on Lake Street or buy one at the Apple Store or on Apple’s official website. Procuring an “official” Apple adapter on Amazon or other vendors can be confusing.

If you are unsure of which adapter you need, please send us an e-mail at AV@FPM.WISC.EDU.

Apple Laptops: How to look up your Operating System Version

In recent years, Apple has been making many changes on how we connect MacBooks to projectors, monitors and other devices. Therefore, connecting to a Wireless device, unfortunately depends on what your operating system is. It is highly recommended that you look up what operating system you have on your MacBook. Here’s how to do it:

Step 1: On your MacBook display, move the cursor to the upper left hand corner of your display and click on the Apple logo and then click on “About this Mac.”

Step 2: A window will pop up resembling the screenshot below.

If you are in a classroom that has an older Wireless device, you’ll only be able to use it successfully if your operating system version is no higher than 10.15.2. Anything higher like Big Sur or Monterey, it will not work.

  • OSX 10.10 Yosemite
  • OSX 10.11 El Capitan
  • OSX 10.12 Sierra
  • OSX 10.13 High Sierra
  • macOS 10.12.6 Mojave
  • macOS Catalina

If you are in a classroom with a newer Wireless device, then you’ll be able to connect to it with no problem. However Apple’s older operating systems have different ways to connect to the AV System than a newer operating system:

  • OSX 10.10 Yosemite
  • OSX 10.11 El Capitan
  • OSX 10.12 Sierra
  • OSX 10.13 High Sierra
  • macOS 10.12.6 Mojave
  • macOS 10.13.6 Catalina

If your operating system is very recent like the below, then you’ll have to connect to it  differently than you would with Apple’s much older operating systems:

  • macOS 11.6.5 Big Sur
  • macOS 12.3 Monterey
