Color Correction does not work properly when
the input signal level is lower than 0.5 Vp-p or
higher than 1.0 Vp-p.
The size of the window may not be appropriate.
Use the Pattern.html file for setup or adjust the
size of the window.
The termination switch on the rear of the monitor
should be set to 75 Ω position (default) when
connecting the monitor with BNC cable.
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 31 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 18.
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.
•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.
• For problems with the USB function, refer to the troubleshooting on page 39.
