Rotate your VESA plate to face its angled rod threads in the direction you want them to face.
Make sure the Monoblocc logo on the VESA plate is facing towards the monitor and away from the monitor arm, as this is the side with the bevelled VESA holes.
Use the supplied 35mm M4 counter sunk screws with 4x thumb nuts to screw your VESA plate to your monitor arm.
Choose the VESA holes depending which VESA standard your monitor is using. If your monitor follows the 100mm VESA standard, then use the inner 75mm VESA holes for mounting the VESA plate to your monitor arm. If your monitor follows the 75mm VESA standard, then use the outter holes of our VESA plate for monitor arm mounting.
