How to convert LCD to touch screen?
Unplug the monitor power cord and then open the computer monitor housing carefully by removing the screws on the back of the monitor. Clean the LCD monitor screen and then touchscreen overlay from the conversion kit with a microfiber cleaning cloth.
Orient the LCD monitor so the screen faces upward then you have to remove the front monitor frame. Install the touch screen overlay over the LCD monitor. Install the screen overlay controller inside the monitor housing if there is extra room. This is the small electronic board that attaches to the touch screen overlay.
Replace the front monitor frame over the screen overlay. You have to make sure that the sides of the touch screen overlay stay parallel to the sides of the LCD screen. Set your monitor back to an upright position. Plug in the cable to the monitor to your LCD and the power cord. The touch screen overlay will be recognized and installed.
The original LCD monitor will still be used to display video through the touch screen overlay. You can test the touch screen with different programs on your LCD.
