44 OPERATING THE DISPLAY
SCREEN ADJUSTMENTS
The screen adjustments described in this manual are designed to set image position and minimize
fl icker or blur for the particular computer in use.
The monitor is designed to provide the best performance at resolution of 3840 × 2160, but can not
provide the best at resolutions of less than 3840 × 2160 because the picture is automatically stretched
to fi t the full screen. It is recommended to operate at resolution of 3840 × 2160 in normal use.
Displayed text or lines will be blurred or irregular in thickness when the picture is stretched due to
the screen enlargement process.
It is preferable to adjust the image position and frequency with the monitor controls, rather than
the computer software or utilities.
Perform adjustments after a warm-up period of at least thirty minutes.
Additional adjustments may be required after the Auto Adjust depending on the resolution or
signal timing.
The Auto Adjust may not work correctly when displaying the picture other than the screen
adjustment pattern. In this case, manual adjustments are required.
There are two ways to adjust the screen. One way is automatic adjustment for Position, Clock and
Phase. The other way is performing each adjustment manually.
Perform the Auto Adjust fi rst when the monitor is connected to a new computer, or resolution is
changed. If the screen has a flicker or blur, or the picture does not fit in the display area after
performing the Auto Adjust, manual adjustments are required. Both adjustments should be made by
using the screen adjustment pattern (Test.bmp) obtained via the IIYAMA web site (http://www.iiyama.
com).
