7. TROUBLESHOOTING
Points to check with possible solutions
! When the screen image is changed after displaying
the same image for a long period, an afterimage
may appear. The "Afterimage" can be removed
gradually by changing the displayed image. Use
the "Off Timer" function and avoid keeping the
screen on all the time. (p.20)
! This is due to the characteristics of the panel itself
and not the LCD product.
! Leaving the screen white may solve the problem.
! Change the mode in <Signal Filter> in the <Screen>
menu.
! <Smoothing> is disabled when the screen is
displayed in the 1280 x1024.
! The image size is doubled both in horizontally and
vertically to (i.e. 1280 x 960 enlarged from 640 x
480) provide clear focus which does not require
this function.
! The adjustment lock is probably on. To unlock:
switch the LCD monitor off. Then, while pressing
the Auto adjustment button, switch the power on.
(p.20)
! Check that the Fine Contrast mode is not activated.
(p. 17)
! Check that the Main menu of ScreenManager is
not activated. (p.19)
! The adjustment lock is probably on. To unlock:
switch the LCD monitor off. Then, while pressing
the Auto adjustment button, switch the power on.
(p.20)
! Use the graphics board's utility software to change
the input signal frequency.
