Question about Samsung Qb65h-Tr

I don't use the APS but:
Yes, you can operate the laptop with the device. This works fine for the most part, but you have to take into account that the interface uses other tools (pen) that are not always well implemented. With the finger rather. Then I have made the experience that a high resolution laptop (surface book for example) can be a transmission delay or overload for the system.
I've had the device for almost a year. Sometimes I'm thrilled, sometimes not (because of bad connection, respectively image delay, or no connectivity); maybe it's me and my inconsistency to deal with it more. The instructions for use are rather rudimentary. The hotline was very friendly and helpful :-)
