got a raspberry pi 2 and want to see if it's working

i have a vga monitor

got a hdmi 2 vga converter, the converter is working, tested it with the r7 graphic card

using a working 5v,max1.5A charger for the raspberry(rasp is using only 1A)

the monitor detects the cable but no signal

nothing else is connected, only the monitor and the charger

the hdmi 2 vga is a Goobay 51758 model

i have read that an unpowered converter may require too much power for a raspberry

but i am seeing an official converter: PI-VIEW HDMI to VGA Adapter Cable for Raspberry Pi Computer Board

this product also is in the same store with the raspberry, and it is stated that it is to be used with the raspberry

but i am also seeing this: "Note: It is recommended that Raspberry Pi is powered by an external, mains power supply when Pi-View is connected and in operating."

if i will buy the new converter and using the same charger will make a difference ?

edit: sorry that i say goobay 51758 but on the package it isn't too much to read but item no:51758 but my product it looks like a Aculine AD-004 the first image on the google with the search "Aculine AD-004". it is same color white but a little shorter like the Aculine, and on the back also includes for audio
