Just tried go single-head turning off the built-in LCD and it is working.
Today I had the opportunity to hook up the laptop to a couple odd monitors (I have a collection of "interesting computers" and recently got a couple Intergraph behemoths with coax and DB-15 connections). All were misdetected and the same rendering and pointer confinement anomalies happened.
