Q: What should I do if I find that the touch LCD monitor is foggy?

A: This is a normal phenomenon caused by excessive temperature difference and high humidity. When the touch monitor has a foggy screen. You can't wait for the fog inside the screen to dry up. The LCD monitor must avoid water. If you turn on the monitor and find there is fog on the screen, you can gently wipe it off from the outside. If it is the internal fog, then you should turn off the monitor, use a desk lamp to dry the mist in the LCD screen or put some desiccant next to it to absorb less moisture. Don't think that it's good to have the LCD screen facing the sun, which will dry out the internal fog, but at the same time will cause the internal components to deteriorate.
