Button lockouts

menu is closed. Holding down the power button or Menu button for 10 seconds disables that button. You can
re-enable the button by holding it down again for 10 seconds.
Optimizing image performance (VGA input)
If you would like to customize your settings, this section describes how to manually optimize your monitor's
image.
You can adjust two controls in the on-screen display to improve image performance: Clock and Phase
(available in the OSD menu). Use these controls only when the auto-adjustment function does not provide a
satisfactory image.
NOTE: You can adjust the Clock and Phase controls only when you use an analog (VGA) input. These
controls are not adjustable for digital inputs.
The Clock must first be set correctly because the Phase settings are dependent on the main Clock setting.
● Clock–Increases or decreases the value to minimize any vertical bars or stripes visible on the screen
background.
