n The screen adjustments described in this manual are designed to set image position and minimize flicker or blur for the particular computer

in use.

n The monitor is designed to provide the best performance at resolution of 1280 × 768, but can not provide the best at resolutions of less than

1280 × 768 because the picture is automatically stretched to fit the full screen. It is recommended to operate at a resolution of 1280 × 768 in

normal use.

n Displayed text or lines will be blurred or irregular in thickness when the picture is stretched due to the screen enlargement process.
n It is preferable to adjust the image position and frequency with the monitor controls, rather than with computer software or utilities.
n Perform adjustments after a warm-up period of at least thirty minutes.
n Additional adjustments may be required after the Auto Set-up depending on the resolution or signal timing.
n The Auto Set-up may not work correctly when displaying the picture other than the screen adjustment pattern. In this case, manual

adjustments are required.
