I'm trying to set up a 24" monitor with my SP4 to work as a standard dual monitor setup. The 24" monitor on the left as the primary with the Sp4 on the right as the secondary screen. It's working OK except the task bar still appears at the bottom of the SP4 screen and the SP4 still seems to work as a primary in some ways. I thought I had this working correctly when I tried it out a week ago before buying the new monitor but it's not working right now. Any thoughts about how I can get this working right?
