Touch function issues
The icons can be touched but the drawings cannot.
Drawing and erasing do not work when the Source window
is open.
Touching does not work when HDMI connection is used.
I use two pens, but they do not work well.
Touches break, reaction speed gets slow, and so on.
Use the provided product-specific pen.
In the PIP mode, the drawing function is not supported within the Source window. In the source
window, drawings in a PC application such as Paint are made by that PC application.
When the product is connected to a PC, make sure that the PC screen is in the full screen mode
(landscape).
Check whether the TOUCH OUT port on the product is connected to a USB port on the PC using
a USB cable.
Make sure that there is enough space between the two pens at multi-touching.
Make sure that there are no foreign substances on the screen surface.
Check whether the screen is broken.
Make sure that the product is not exposed to direct sunlight.
