Problems
5) Characters are too large.
Points to check with possible solutions
• 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 perform-
ing 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 resolution. Higher
resolutions allow you to display more information on the screen.
Changing the resolution
If you are using a Macintosh, you can change the resolution from the APPLE menu by
selecting “Option” from “Monitor” or “Sound & Display.” If you are using a PC other
than a Macintosh, refer to the manual for your PC or graphics board for information.
Please refer to both the graphics board and monitor manuals for the scanning frequency
compatibility.
Problems
6) Two horizontal hairlines are
visible on the screen.
(only T68)
Points to check with possible solutions
• These are dampening wires. Dampening wires are
used to support the CRT’s aperture grille, and are
visible as thin dark lines across the screen. All
EIZO aperture-grille type CRTs include two such
horizontal wires.
The aperture grille itself is a grid of taut metal
filaments that spans the entire screen from top to
bottom.
