Control Panel Settings: If you are using an MCGS HMI connected to a PC environment (like Windows 10/11), you may need to use the Windows Tablet PC Settings in the Control Panel to reset the touch input. mcgs hmi touch calibration
Resistive Touch Screens (Older MCGS models like TPC7062Ti): These rely on pressure. Two conductive layers make contact when pressed. Over time, mechanical stress, dust, or minor screen misalignments can cause the coordinate mapping to shift.
Capacitive Touch Screens (Newer MCGS Pro models): These use the electrical properties of the human body. While more durable, they can suffer from calibration drift due to static electricity, temperature fluctuations, or firmware glitches.
