I got a velocity w220 monitor a couple of days ago..... But after i hooked it with my MBP. the monitor only can be used as EXTENDED Desktop, in other words.... I can drag some items, applications or windows to the monitor, which doesn't make significant differences comparing to a normal monitor at this point, i can live with that. But, still, i want some help to see if i can somehow solve this problem to operate smoothly. PS: If i use windows OS, i can hook MBP with the monitor seamlessly. So, my thought this problem could possibly come down to the OS issue.
