Hello,I am Pete, and I'll be happy to assist with your question today.
To fix this, the touchscreen will need to be recalibrated. This will involve creating a new calibration file.
To recalibrate it, press and hold the reset button on your unit briefly.
Next, press and hold the power button until the screen appears with white text on black background, then you can release the button. You will see a line on the screen that looks like this:Touchscreen calib. data: 76 932 140 861Beware! On THAT screen, the data is MinX MaxX MinY MaxY. Don't use that order when you create your cal.txt file! Anyway, this shows you where the unit calibration is by default if there is not any cal.txt file to change it., so you use this as a starting point for your adjustment. If your screen showed the numbers above, that would the same as if you had created the cal.txt file that looked like this: 932 76 861 140You should create the file with Notepad or another very basic text editor that will allow you to create the file as BARE text and does not require line break at the end of lines.
