It may help if you would tell us how you found that out.
E.g. your machine's spec's has the same kind of vague wording regarding its Touch implementation as the others
Integrated multi-touch screen supporting finger touch
I had to do a lot of digging to figure it out, personally. The first thing I did was check out the device manager. Windows 8 listed it as a USB Input device. I was able to tell which one it was because I knew it was a USB touch screen. When you look at the
properties of a device the location section should say Port_#XXXX.Hub_#**XXXX,**where X is some kind of number. The other possibility I've seen is a ps/2 touch controller, in which case I'm not sure where to find it.
Anyway, Once you find what you suspect to be the touch screen in your device manager, you could try right-clicking and disabling the device to see if you lose any response from the hardware, if you had any before. Once you know for sure which device is is,
go into its properties and navigate to the "Hardware ID's," section, and run a Google search for the ID's. That was enough to identify it for me.
Touchbase's website is also a major help for the ZX series, since their drivers support it. Here you can just see if they list your model, and it saves you a ton of time.
