You may have encountered it when you click on the ELO touch screen display, but the elo touchscreen monitor has nothing to do with it. This is especially true for elo POS touchscreens that are critical to your business.
You can solve it by the 4 steps taught below.

• 1、Determine the real source of the elo touch screen problem.
  

  Check all of your cables and make sure everything is hooked up correctly.
  Then restart your system. If you’re using a serial port, you should also make sure your ELO touch display is connected to the serial port.



• 2、Detection software
  

  Software problems are determined by a basic hardware functionality test.
  If the hardware transmits touch coordinates correctly, then the problem is with the driver or application software.
  You haven’t updated your software or installed the proper elo touchscreen drivers.
  You can find all of this on ELO’s website.
  Simply download the update or right driver, follow their installation process, and you should be good to go.



• 3、Detection Hardware
  

  Hardware problems may be caused by the touchscreen, controller, cabling, power supply, or by the integration of the touchscreen components in the display.



• 4、Buy a new part or call the professionals
  

  If you’ve followed all of these steps and still don’t have a resolution, it might be time to call the professionals.
  And also you can buy a new elo touchscreen glass part to replacement repair by yourself.
