I was gifted a functional monitor (claimed) that was missing its power cable, and I am not entirely sure what the key elements are to look for in a replacement; and I'm assuming it doesn't like the wrong thing to be plugged in.
It is an Asus model no VZ279 version no VZ279HE.
Lists the power as 19v (dc) 1.75A
What is the 1.75A part and is it important?
