2.2 Adjusting the monitor
• For optimal viewing, we recommend that you look at the full face of the
monitor, then adjust the monitor to the angle that is most comfortable for you.
• Hold the stand to prevent the monitor from falling when you change its angle.
• The recommended adjusting angle is
+20˚ to -5˚ .
-5°~ +20°
It is normal that the monitor slightly shakes while you adjust the viewing angle.
