External touchscreen unable to calibrate#255
It’s not possible to calibrate the external screen. The touch point is above the target touch point, so it is “out of the screen”. We’ve tried several models of touchscreens. It also appears that the difference between the touches point on the screen and the triggered point increases from top to bottom.
Please indicate the Manufacturer and Model of your touchscreen and the touchscreens you have tried. With these issues, it is always of utmost importance that we can somehow reproduce the behaviour.
Thanks,
Denis
In general we advice against using these “generic” touchscreens - they have not proven to be reliable and also we have had, especially, with the Wemaxit screens, mixed results with the same screen which was purchased at different times. These OEM screens tend to change their touch screen controllers depending on availability; we advice to use the Iiyama Prolite 2252MSC.
