Yoga 2 Pro reacts to Synaptics pen

Hello,

Purchased a Yoga 2 pro, with the understanding that there is no digitizer for stylus. Sure enough, WACOM and N-Trig stylus did not respond. Imagine my shock when attempting to use a Synaptics stylus the Yoga actually responded to it. The behavior was odd, multiple touches up and down the screen vertically. Clearly the Yoga and Synaptics stylus were not working properly but, still, it responded.

What is known about how the Synaptics digitizer/pen works? Drivers? Is it all in the BIOS? Registry settings?

Anybody else experience this?

Thanks

Paul

 

The Yoga 2 Pro has a capacitive touch screen. My guess is that the Synaptics stylus represents some property of the electron sink, (or spike? I don't know how capacitive displays work exactly), of a finger.

It will be interesting to see how the new Wacom AES styluses behave on non Wacom capacitive screens, since they're designed to conduct as well.

 

Do n-trig pens also conduct? Maybe this has to with the display or trackpad being synaptic based?
