When browsing the Internet or using applications on your computer, there may be times when you feel a touchscreen would be beneficial. There are conversion kits you can purchase to transform your computer's LCD screen into a touchscreen, allowing you to use your computer as you normally would -- and as a touchscreen device.
Unplug your computer monitor's power cord. This will prevent electrical shock. Use the screwdriver to remove the screws connecting the back panel of the monitor to the screen. Place the screws in a plastic bag so you will not lose them.
Clean the monitor's LCD screen and the conversion kit's touchscreen overlay with a clean microfiber cloth. This will prevent dust from getting caught in between the screen and the overlay.
Lay the monitor down with the screen facing upward, and remove the frame that surrounds the monitor. Place the touchscreen overlay over the monitor with the touchscreen display facing outward. Consult the kit's manual for complete instructions.
Insert the screen overlay controller into the monitor housing by attaching the small electronic board inside the housing to the overlay controller. If there is no room for the wires, lead them through the back casing of the monitor, along with the pre-existing monitor cables.
Put the monitor's frame back onto the computer, over the touchscreen inlay, keeping the overlay parallel with the sides of the frame. Flip the monitor over and reattach the casing screws that you removed earlier. Do not tighten the screws all the way, as this may crack the touchscreen overlay.
Return your monitor to upright position and plug in the video cable that runs from the monitor to the computer. Plug the monitor's power cord. Plug the touchscreen kit's power cord into the computer. Plug the USB device that came with the kit into your computer to install the drivers on your computer.
