receiving first and second pen signals;
synchronizing the pen to first and second digitizers based at least partly on the first and second pen signals, the first and second digitizers coupled electronically to the first and second touch-screen sensors, respectively, and configured to provide respective first and second pen signals responsive to action of the pen on the first and second touch-screen sensors;
enabling pen tracking by any of the first and second digitizers conditionally, based at least partly on the first and second pen signals;
exposing a result of the pen tracking to an operating system of the touch-screen system.
