I recently bought an Inspiron 7435 2-in-1 and was looking to buy a third party stylus/pen, however I haven't been able to find out definitively whether the laptop has microsoft pen protocol/MPP, AES or another protocol. Obviously I don't want to buy a stylus only to discover it's not compatible with my device!

If anyone knows which protocol/s recent dell models use that would be super helpful. Thanks!
