How do I change what is shown between two displays? (Windows and Mac OSX)
WINDOWS: How do I change what is shown between two displays? (Windows) There may be times when you want the content shown on the built-in computer screen to be the same as what is shown on an external display (i.e. a TV, monitor or AV system). You may also want to show different content on each display. This document addresses both options. If you would like to change the video output option on the Windows computer that you are using: Hold down the Windows key (lower left corner of your keyboard, the key that has a square made of 4 smaller squares) and tap P as in Project. On your primary computer screen, you will be presented with 4 options. When the options list is displayed, you can release both keys. The list will remain displayed until you either select an option or click anywhere outside of the list, clicking outside of the list will is the equivalent of clicking Cancel. When the list of options is shown, you have several options to select a setting (Listed below). If you are making this change in a classroom, please be sure to change it back to Duplicate or reboot the computer when you are done with your class. This will put the room in the default setting for the next person using the room. Computer video output options PC Screen Only - This option will turn off the video feed to the external display (TV, monitor or AV system) and only show on your laptop Duplicate - This will send the same visual to your laptop's built-in screen and the external display (TV, monitor or AV system). This is the default setting for all classrooms Extend - This allows for the laptop built-in screen and the external display (TV, monitor or AV system) to show different content at the same time. This is used for PowerPoint notes on your laptop and the presentation on the external display. Second Screen Only - This option will turn off the video feed to the laptop's built-in screen and only show content on the external display (TV, monitor or AV system) . Options for selecting an option Option 1 - Use the mouse and click the desired setting. Option 2 - Use the up and down arrows and tap the Enter key when you have selected the desired option. Option 3 - Tap the Windows Key + P combination again and the selected option will move to the next option down the list. MAC OSX: These steps require the computer and the External Display (i.e. TV, external monitor or AV System) to be connected and both device be active. Steps: Step 1 - In the top left corner of your screen, click the Apple Step 2 - Select System Preferences Step 3 - Select Displays You will now be shown two windows, one window will allow you to adjust the visual settings on the laptop's built-in screen and the other will (by default) allow you to adjust the external display. Each window will have a drop-down list of connected displays. Unless you have changed the computer settings, the computer's screen will be identified as Built-in Display. The external display will be represented by either Display or the name of the device. A common name to be displayed if connected to a classroom AV system will be ExtronScalerD. ExtronScalerD is how all Classroom AV switches present themselves when connected to a computer. Step 4 - In the window labeled Built-in Display, select the center tab labeled Arrangement Step 5 - On the left side of the window towards the bottom (above the drop-down for AirPlay Display, you will find a checkbox labeled Mirror Displays. When Mirror Displays is checked, the same content will be sent to the Mac's built-in display and the external display. If the box is unchecked, the two displays will show different content. If you are making this change on a teaching station computer in a teaching environment, please be sure to either reboot the computer at the end of class or make sure that the Mirror Display option is Checked. This will ensure that the settings are in the default condition for the next person teaching in that space.

Classroom AV Systems: What can I expect?
If you are experiencing a technical issue in a classroom, please feel free to call the Audio Visual Services team at 978-232-2152. All permanent classroom AV systems have the following features by default. A dedicated teaching computer. * All classroom Teaching Computers: - Use a generic username and do not have a password. If you are ever prompted for a password to use the computer, reboot the computer and it will automatically log in. Do not attempt to sign in with your Endicott credentials as it will not work. - Will erase any and all changes made to it when rebooted for any reason. Downloaded files and/or installed programs will be deleted permanently when the computer restarts. - Have full access to the internet. - Have the ability to share a mobile device over the WiFi (See AirServer). - Have Microsoft Office. - Have a media player installed. - At least 1 empty USB port to allow for device charging, data storage device transfer (USB Memory stick) or wireless slide advancer (provided by the faculty or academic school). A large format display All classrooms have either a projector or a flat panel TV depending on the space. If the room has a projector, there will be either a screen or a projection whiteboard. FABRIC PROJECTOR SCREENS ARE NOT WHITEBOARDS AND SHOULD NEVER HAVE A MARKER USED ON THEM. A Classroom AV Control panel (For more specific info on control panels, CLICK HERE) All permanently installed Standard Classroom AV Systems are equipped with a control panel on or within arms reach of the teaching station. Most teaching station control panels are built into the teaching station itself while some older model systems have the panel installed into the wall close by. All classroom control panels have the ability to: - Turn the large format display on and off - Select the input going to the display and speakers - Engage and video mute (only stops video from going to the main display, it will not impact shared screens in Zoom meetings). All mutes will automatically disengage after 5 minutes of not touching the control panel. - Audio Volume control Full Wifi coverage All academic spaces on campus are fully covered by the college Wifi network. There are no exceptions to this unless there is a system outage taking place. In order to connect a laptop to the wifi network, you will need to enter your Endicott issued email address as the username and the appropriate password for said account. If you intend to use systems like AirServer (See below) you must use a wifi that does not include the word Guest. Guest wifi networks have access restrictions for security reasons and there are limitation to what can be done on that network. If you are having issues connecting to the college wifi network, please click New Ticket in the upper corner of this page to begin the support process. AirServer Software This is a software package that is installed on every teaching station computer on campus. It allows for computers connected to a non-Guest wifi to share video live without a wired connection. Copyright protection issues have been known to crop up with this service depending on the content in question. Please test the content with the room's large format display on before it is critical. For more information on AirServer (CLICK HERE) Classroom Hybridization kit This kit is installed in all classrooms to allow for hybrid teaching models. The kit includes an HD Web Camera (Webcam) and a USB room microphone. Both of these items are covered in greater detail in a different document (An Intro to Classroom Hybridization Kits). These parts are always active when the classroom computer is on and awake. The parts were selected and installed with the intention of minimizing physical contact with the devices. Speakers for computer audio For classrooms where a TV is the main display, the audio will be coming from the TV. In rooms with projectors, there are either wall mounted speakers on either side of the projector image or there are ceiling recessed speakers. Ceiling recessed speakers are most common across campus and are made to look like they are part of the ventilation system. At least an HDMI laptop input cable All classrooms will have at least 1 laptop connection cable in addition to the built-in classroom computer. The minimum connector is a HDMI cable. If your laptop computer does not have an HDMI port, you are responsible for providing an adapter that allows your laptop to connect to an HDMI cable. Most rooms however, do offer additional connection options including USB-C, MiniDisplayPort and VGA. VGA is being retired from service and as rooms are upgraded and/or go through a heavy rewire as part of the college's ongoing classroom technology replacement cycle, VGA is being removed. A standard electrical socket All classroom teaching stations have at least 1 electrical outlet either near the control panel or on the front of the equipment rack (when visible). This outlet is meant to allow for faculty laptops to be plugged in for classes without needing to stretch the power cord across the floor creating a tripping hazard. * Nearly all classroom Teaching Computers are Windows 10 machines with a small number of exceptions being Mac OSX computers.Windows computers are the default teaching computer operating system. Macs are only in place for program specific needs in lab environment and requires the Academic Dean to work with Academic Technology.

An Intro to Classroom Hybridization Kits
Intro: Classroom Hybridization Kits are a standardized set of parts installed into all classroom spaces intended to permit Hybrid learning from any classroom space on campus. All classrooms on campus with very few exceptions are equipped with identical USB microphone (Samson Satellite) and a USB web camera (HuddleCamHD). These parts were installed to augment the web camera and microphone that is already in place for being built into all but 5 classroom teaching computers. For the 5 spaces that do not have a microphone and camera built into the computer, a second HuddleCamHD was installed. This means that EVERY classroom on campus is equipped with 2 camera and at least 1 microphone to allow for teaching student(s) online. The inclusion of the Hybridization Kits allow for ad hoc session recording and synchronous teaching with any number of people at a distance. Both the camera and microphone were selected and installed to require as little physical contact as possible. When the classroom computer turns on, so will the microphone and cameras. When you open the Zoom app or sign into Canvas and start a Collaboration session, the cameras and microphone will be available to you. The parts that you can see: In addition to the microphone and web camera(s) there are other components that reside inside of the teaching station to help ensure that the system is as reliable is possible with very little if any need for adjustment or physical contact. Settings for the WebCams in Zoom: In the rooms where the computer does not have an Integrated Camera, there will be 2 HuddleCamHDs shown. If additional video inputs are attached to the computer, this list will get longer. A close up on the microphone: Settings for the microphone in Zoom: You will note that the HuddleCam Microphone is also listed, this is there to act as an emergency backup microphone. The audio quality of the HuddleCam is noticeably lower than the Main Room Mic, but if there is an issue, it is available if you don't feel that you have the time to call AV for assistance. To view the audio menu in a Zoom meeting, look in the lower left corner of the Zoom window and click the up carrot (depicted below circled in red). This will display the Call Audio Settings. Click the up carrot to display audio settings In the audio menu, you have the ability to actively change between different microphone and speaker options that are detected by the computer. The best quality option for audio inputs and outputs are noted by having Use this one after the description. The prescribed best audio devices have been set as the system defaults for when Zoom sessions start. If you believe that there is an issue with the microphone or speakers, Zoom has a built in audio testing system. To begin a speaker and microphone check, look towards the bottom of the audio menu for Test Speaker & Microphone... the test process begins with a repeated playback of the Zoom incoming call ring. If you can hear the chime through the correct speaker, click Yes. If you can't, select a different speaker option from the drop-down menu until you find an output that is working or call AV support at 978/232-2152. When you can hear the chime and have clicked Yes, the window will change to the microphone check, you will be prompted to speak and then allow Zoom to play the audio back to you, if you can hear your playback and believe that the correct device is selected, click Yes to exit out of the test window or change the microphone to another listed option until you find a working option. If you believe that there is a problem with either the microphone or speakers for the room, please call AV support at 978/232-2152 for immediate assistance or submit a ticket here in FreshService. ----- This concludes The Intro to Classroom Hybridization Kit. ----

The webcam is showing Black or Red
Most Lenovo computers on campus that have a built-in camera to allow for Zoom meetings and other online conferencing systems. Many of these cameras are also equipped with a physical Privacy Cover that can be slid in the way of the camera lens to physically prevent the camera from being used. If the camera app or web conferencing software is open but is showing either Black or Red, the first thing to check is if the computer has a privacy cover for the WebCam. If the computer does have a privacy cover, the probable cause for the image issue is that the cover is in place. If the computer shows an error message, a support ticket will be needed. In all cases where a Privacy Cover is installed, the switch to open and close the cover is located within one inch of the camera lens. WebCam covers are in one of 3 places depending on the model of computer. 1 - Behind the WebCam Lens on the back of the computer Computer WebCam Privacy cover is moved by sliding the tab side to side. 2 - Directly above the WebCam lens Computer WebCam Privacy cover is moved by the small red tab above the lens 3 - Directly covering the lens.

Troubleshooting System Audio
It is understood that an outside laptop is desired for use in the event/class session, but the computers that are assigned to classroom spaces and auditoriums are installed and set up for the greatest reliability. Once the Speaker system is confirmed to be working with the room's assigned computer, the input can be changed to a laptop. Step 1: On the system control panel, select the room's assigned computer. Even if the room computer already shows as selected, press the button again. This will re-send the command(s) to make sure that the system is in the correct mode. Step 2: On the system control panel, set the Computer Volume to between 60% and 80%. If the volume already shows at that level, make at least some adjustment to volume. This will re-send the command(s) to make sure that the system is in the correct mode. Step 3: Confirm that if there is a Computer Volume Mute option on the AV Control panel, that the button is NOT red. Red mute buttons indicate the the mute is active. Step 4: If the room's computer is a Mac, you can skip this step. Find the volume adjust icon in the lower right-hand corner of the screen and click the icon once. In the pop-up window that is now shown, move the vertical bar to the left or right along the line until the indicated number on the right side of the window shows between 60% and 80%. If the number is already indicating a number in that range, please click the vertical line. When the volume adjustment bar is moved or clicked, the PC will play a short chime through the selected speakers. Step 5: If you are unable to hear the chime from the room speakers or you hear it from an unexpected location, look above the volume adjustment bar and confirm that the name being displayed is either Room Speakers: Use this one or ExtronScalerD. If the name being displayed is neither of these options, click on the up arrow above the volume number. This will display the list of all speaker systems that are available to the computer. If the selected speaker was changed, repeat Step 4. If at this point you are still not hearing any sound, please call AV Services at 978/232-2152 If you do hear the chime but you are having audio issues with Zoom participants (CLICK HERE).

Playing a DVD in a Classroom Computer
Official support of DVDs ended on July 1st of 2019. The main cause of this policy change was due to several computer manufacturers announcing that they will no longer include DVD drives in their computers. Best efforts will be made to obtain teaching station computers with DVD drives for as long as they are available. It is recommended that online versions of such videos be located whenever possible. If you experience problems playing a DVD, Campus tech support staff will make a best effort attempt, but there have been cases where a DVD is damaged or not compatible with the drives available on campus. No Endicott provided laptop computer has been equipped with a DVD drive for several years. iMac teaching computers are also not equipped with DVD Drives. If the space that you are teaching in is equipped with a laptop or iMac, please submit a ticket with AV Services to arrange to sign out a USB DVD drive. Most classrooms are equipped with an "All-In-One" computer. On these machines, look to the side of the monitor and you will find a rectangular outline with a slightly raised button. Pressing this button will trigger the opening of the DVD drive. When inserting the disk, the disk's label should be facing you. Be sure that the side of the disk closest to the computer is inside of the DVD drive housing and the disk is snugly held by the free-spinning axle of the drive. When gently pushing the DVD into the computer, there should be very little to no resistance to movement until a gentle click of the drive door closing. If there is physical resistance to inserting the disk, DO NOT PUSH. Remove the DVD and attempt to close the drive, the same amount of resistance should exist with an empty drive as a drive with a DVD in it. If the computer is a tower type computer (only 6 classrooms on campus), the DVD drive can be located in the equipment rack on the Lenovo ThinkCentre. On these machines, you will find a rectangular indentation on the front of the computer. In that indentation, you will find a raised rectangular button. Pressing this button will trigger the opening of the DVD drive. When placing the DVD in the drive, the label should be facing upwards. There should only be resistance to the drive closing when the door gently clicks shut. Once the DVD is in the computer: Step 1 - Look in the taskbar at the bottom of the computer and click the VLC logo (an orange and white highway cone) once. If the logo is not in the taskbar or located on the computer screen, click on the Windows Key in the bottom left corner and type VLC. The program is installed on all teaching computer by default and it will show in the search results. VLC Media Player Logo Step 2 - With VLC Open, click Media located in the menu bar at the top of the window. Step 3 - On the Media menu, select Open Disk. Step 4 - A window will then open allowing you different menu options to be changed. Only click Play or tap the Enter key of the Keyboard. So long as there is only 1 DVD detected by the computer, this menu is not needed. Step 5 - At this point, the DVD menu will appear and you can use the computer's mouse to select different DVD options including chapters or playback languages. Helpful Hotkeys: F = Enter Full Screen viewing Esc = Exit Full Screen Viewing (SpaceBar) = Play and Pause

Classroom Teaching Station Computers: What should I expect?
All spaces equipped with permanent AV technology will have a teaching computer as standard equipment. The AV systems are designed, calibrated and tested to work more reliably with the computer provided. As discussed in Classroom AV Systems: What can I expect?, laptop connection cables are also available. Please reference Classroom AV Systems: What can I expect? for more information on outside laptop connections. Deep Freeze: All publicly accessible computers use a security software called Deep Freeze, this includes all teaching station computers. This software allows Campus Tech to set the computer to a standard setup and lock out any other changes. When a computer that has Deep Freeze is rebooted for any reason, any and all changes that happened to the computer since the lock was activated will be deleted and settings reset. This includes all downloads, installs and web browser cookies. Do not save files on public computers, they will be deleted when the computer reboots for any reason. All public computers are set to reboot overnight every night, this allows for a clean slate for the first classes of the day. It is a recommended first troubleshooting step to reboot the computer if there is doubt related to settings being abnormal. User Account: All publicly accessible computers are set with a generic user account, this includes all teaching station computers. Please do not log out of the computer at the end of your class. If you are asked for a password by the computer, reboot the computer and it will automatically sign into the correct account. This auto-sign in process is not applicable to iMac teaching station computers. If you teach in a room equipped with an iMac, please contact the lab manager. Web Browsers: All publicly accessible computers have at least 2 web browsers installed on them, this includes all teaching station computers. Chrome is set as the default browser. MS Office: All publicly accessible computers have the Microsoft Office Suite installed on them, this includes all teaching station computers. Word, PowerPoint and Excel are standard issue. Do not save files on public computers, they will be deleted when the computer reboots for any reason. Adobe: All publicly accessible computers have at least Adobe Reader installed, this includes all teaching station computers. Depending on the expected usage of the computer, the full Creative Suite may also be installed. Media Players: All publicly accessible computers are equipped with at least 2 media player software options, this includes all teaching station computers. The default media player is VLC Media Player. Zoom/Skype: All publicly accessible computers have both Zoom and Skype installed, this includes all teaching station computers. SPSS: All publicly accessible computers have the Statistical Package for the Social Sciences (SPSS) installed, this includes all teaching station computers. Requesting Additional Software: Requesting additional and/or specialty software to be installed on publicly accessible computers required a ticket in the FreshService system at LEAST 30 days prior to the start of the academic semester. All public computer (including lab and teaching station computers) are set to standard software packages based on the known requirements of the computer's use. This software package is locked in and will not be altered once an academic semester has started in order to ensure reliability throughout the semester. Only if an existing software has a known issue that will interfere with classes will a mid-semester change be deployed.
