It tells you the specs:
"VESA 75x75mm / 100x100mm compatible "
So mesure the screw holes on the back of your 17" monitor and then see if they are within the specs of: VESA 75x75mm / 100x100mm compatible.
It should work and no the shape of the bracket that holds the monitor STAR, DIMOND, CIRCLE, SQUARE does not matter as long as those holes line up.
Good Luck ! (Peace!)
