Points to check with possible solutions
The CRT is not warmed up. Allow 30 minutes for the
monitor to stabilize.
The Adjustment Lock is probably on. To unlock: switch
off the monitor power, then hold down the AUTO-
SIZING button and switch the monitor back on. See
page 14.
The AUTO-SIZING function is intended for use on the
Macintosh and on IBM compatibles running Windows.
It may not work properly if either of the following
applies.
- You are running an AT-compatible PC on
MS-DOS (not Windows).
- The background color for the “wallpaper” or
“desktop” pattern is set to black.
Some signals from graphics boards may not function
properly.
Explanation of the Characteristics of CRTs
When the monitor is not fully warmed up, the screen may look slightly colored, e.g.
reddish or bluish. This phenomenon is due to the unstableness of the electron gun during
its warm-up period. Please wait for about 30 minutes until the monitor stabilizes in order
to gain its proper color.
•
A solid-color screen (i.e. red, green, blue) may appear for an instant while performing the
AUTO-SIZING function, althought, this phenomenon is not a failure.
