Symptom: Caller states that they are having issues with the touch screen.

  • Having issues hitting buttons
  • When hitting a button another button is getting clicked.

Note: When performing calibration, ensure that the end user is touching the target until it changes to color or the next target displays, otherwise the calibration will not work.

Step 1: Determine type of monitor

  • If the location has older EGalax touch monitors, Proceed to Step 2.
  • If they are using new ELO touchscreen monitors, Proceed to Step 3.


Step 2: EGalax Monitor Calibration

  • Two Methods
    • Navigate Start > All Programs > EGalax > Configure Utility
    • Access Control Panel > Elo > Align > have the caller press the targets.
  • Monitor Mapping
    • Within the EGalax Utility choose Monitor Mapping
    • Have the caller touch the touch panel and skip the secondary touch input since there  is not a touch screen.
    • Clear & Calibrate
    • Test
  • NOTE: Newer versions of these monitors do not have a hardware settings in the Hardware tab.
    • Newer monitors do not require calibration.
    • The monitor utilizes a thin film above the glass that uses the contact points for location.
    • This creates a resistive screen that will require a harder button press to ensure the contact is made with the film and the glass underneath.


Step 3: ELO Touchscreen calibration

  • Pull up the ELO touch application in the start menu
  • Go to common Settings
  • Change mouse emulation to click on touch


Step 4: When there is no dedicated touch utility for EGalax or Elo

  • Use Windows Tablet PC Settings (Windows 10 / Ticket 6110357)
    • Navigate Control Panel > Tablet PC Settings > Setup > Touch Screen
    • Calibrate
    • Test

Step 5: Cleaning the screen

  • Have the caller clean the screen with a lightly damp cloth (Water Only).
    • Make sure all corners and the bottom lip are clean as stuck particles can lead to calibration issues.
  • Recalibrate the screen

Step 6: Determine Hardware or software failures

  • Restart the system and check Device manager for any input devices that have a yellow exclamation mark or a red "X" to indicate any problems.
  • Set the desktop background to black TEMPORARILY (Switch back to which ever back ground was previous used afterwards). 
  • Have the caller look at the display from an angle to see if there is damage.
  • Determine if there is any of the following
    • Visible damage
    • A warped touch panel overlay
    • Areas with signs of wear and tear from usage (Generally around POS and Send buttons)
