Points to check with possible solutions
Chnage the mode of "Signal Filter" function in the
ScreenManager "Others" menu. See page 17.
This may be solved by changing the refresh rate.
Reduce the moiré using the ScreenManager’s “Moiré”
adjustment menu following the procedure below.
1) Set the desktop to an every-other-dot pattern so that
moiré will be visible.
2) Go to the ScreenManager’s “Moiré” menu and adjust
so that moiré becomes almost unnoticeable. See page
12.
3) Change to a different desktop background to reduce
moiré even further.
Change the horizontal and vertical dimensions of the
desplay area.
Change the selected desktop or wallpaper pattern to
any solid color pattern. For detailed information on
how to change these patterns, refer to the
documentation for the PC and operating system.
Flicker will occur with interlaced scanning, or
non-interlaced scanning with a low refresh rate. All
EIZO monitors are capable of reproducing high refresh
rates for non-interlaced scanning. If a problem occurs
when using a non-interlaced signal, try adjusting the
graphics board to increase the refresh rate (if possible).
Refer to the graphics board manual for information.
The CRT is not warmed up. Allow 30 minutes for the
monitor to stabilize.
Flicker
The term “flicker” refers to noticeable shimmering that occurs when the image on the
screen is redrawn (“refreshed”) too slowly. A refresh rate of 80 Hz means the image is
redrawn 80 times per second. Most people will notice flicker at image refresh rates as high
as 60 or 70 Hz, whereas refresh rates of 72 Hz or above usually is not noticeable. Flicker
is known to be the cause of visual fatigue.
