In which case does the touch all-in-one machine need to be calibrated?

In which case does the touch all-in-one machine need to be calibrated? The simple understanding of the touch all-in-one machine is that the computer all-in-one machine plus the touch screen is an interpersonal interaction device integrating LCD, touch screen, computer PC and control system, intelligent office teaching software, high-definition flat panel display technology, multimedia network communication technology and query software. When using the touch all-in-one machine, due to our improper use method, touching the part of the display screen with your finger can not normally complete the corresponding operation. This phenomenon may be a problem in the calibration of the touch screen. In which case does the touch all-in-one machine need to be calibrated? Next, the small editor of Fandou electronic teaching touch all-in-one machine manufacturer will give you a detailed introduction. The specific operation methods are as follows:

1. When the resolution of the touch all-in-one machine is changed or replaced, it needs to be calibrated. The dimensions of all-in-one machines of different brands and models are obviously different, corresponding to different optimal resolutions. When the resolution is changed, the displayed image will be stretched horizontally or vertically, so the touch screen coordinates do not correspond to the program coordinates. At this time, calibration is required.

2. When replacing the computer host, the relative position of the touch all-in-one machine does not change. However, after replacing the computer host, it is difficult to ensure that the corresponding coordinates are consistent with the original host. In this case, the touch all-in-one machine also needs to be calibrated.
