How to attach the monitor base
• If the computer is turned on you must turn it off before continuing. 
Do not plug-in or turn-on the power to the monitor until instructed to do so.
• The following illustrations are for your reference only. Available input and output jacks may vary depending on 
the purchased model.
 Please be careful to prevent damage to the monitor. Placing 
the screen surface on an object like a stapler or a mouse will 
crack the glass or damage the LCD substrate voiding your 
warranty. Sliding or scraping the monitor around on your 
desk will scratch or damage the monitor surround and 
controls.
Protect the monitor and screen by clearing a flat open 
area on your desk and placing a soft item like the 
monitor packaging bag on the desk for padding.
Gently lay the screen face down on a flat clean padded 
surface.
While holding the monitor firmly against the desk, pull 
the monitor stand arm upwards clear of the monitor.
Orient and align the stand base socket with the end of 
the stand arm, then push them together. Tighten the 
thumbscrew on the bottom of the monitor base as 
illustrated. 
Gently attempt to pull them back apart to check that 
they have properly engaged.
Carefully lift the monitor, turn it over and place it 
upright on its stand on a flat even surface.
