Points to check with possible solutions
The monitor emits a humming noise when
executing automatic degaussing at power-ON.
This is not a problem.
The monitor beeps at any time. This is not a
problem. See page 36 for full details.
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 19.
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.
Change the resolution of the graphics board to a
higher setting. (Refer to the manual for the
graphics board or PC.)
• A solid-color screen (i.e. red, green, blue) may appear for an instant while
performing the auto-sizing function, this phenomenon is not a failure.

What is Resolution?
Resolution is expressed as the number of dots (pixels) displayed on the screen. A
larger number of dots produces a more sharply defined (a higher-resolution) image.
Note that for a given screen size the dot size decreases as the number of dots
increases: a 640 × 480 (dot × line) resolution uses larger pixels than a 1024 × 768
resolution. The display size of a given font therefore varies according to the resolu-
tion. Higher resolutions allow you to display more information on the screen.
