I was just given a 27" monitor that needs a 19v 3.34A power brick. However, the brick is missing. I have a 20v 7a brick from an old laptop. Can I use that, or does the power need to be exact?
In other research I came across this comment. "Voltage means less than the current rating of the power supply. Your power supply should always be able to safely supply more current than the device will draw."
