I have a HP vf52 LCD monitor that I am looking for a power adaptor for. On the back, it calles for a 12Vold 2.OA (2.OA), what ever that means. Will it accect something a bit larger or Smaller that a 2.OA. What is the min I need to push the monitor to work properly? Thanks Having a hard time finding exactly what it calls for even on Ebay, and hp wants a fortune for theirs. Thanks
