Using the Claridge touchscreen as a display

Before you begin

Plan ahead:  Library IT wants you to have successful meetings.  If you are hosting a conference, meeting, or event that may require extra assistance, such as using a new device, or hosting a webinar or video conference, please send an OTRS ticket to Library IT at least one week in advance to schedule a practice run so that we can accommodate you appropriately.

Touch screen basics

Please keep the following important points in mind while using the Claridge Touchscreen:

  • Only use the Claridge Touchscreen stylus or your finger when writing on the touch screen surface.
  • DO NOT use your personal stylus.  Each stylus is different and can scratch the screen surface.  Only use the Claridge Touchscreen's stylus or your finger to write on the screen surface.
  • The touch screen is not a marker board.  No markers, white board markers, pens, or pencils are to be used on the screen.
  • Screen cleaning
    • DO NOT use any chemicals or fluids on the touch screen monitor, including monitor wipes or sprays. These will damage the monitor.
    • Only a microfiber screen cleaner cloth is allowed. The small black cloth is in the room.
    • Clean the screen before you log on.  If you clean it while logged in, you will open up applications.

Connect your laptop

  • First connect your laptop using the VGA or VGA to Thunderbolt cable, located on the wall under the Claridge Touchscreen Monitor.
  • For Sound -- disconnect the audio cord on the back of the dedicated PC and plug it into your laptop's headphone jack.

  • For basic touchscreen capability -- disconnect the marked USB from the dedicated PC and plug that into your laptop.  The touchscreen driver needs to finish installing before you can use the touchscreen.

  • If the red LED light on the front panel bottom-right corner is on, the display is OFF.


Select the Source button, and use the arrow keys to highlight PC for your connected laptop by VGA or VGA to Thunderbolt.  Then select Source again to confirm the setting.
