Supported Graphics Modes and Refresh Rate Selection
There is no need to choose the highest possible refresh rate when using an
LCD monitor. It is not technically possible for an LCD monitor to flicker. Even at
a refresh rate of 60 Hz you will get an absolutely flicker-free image.
For best results, it is important that you set the graphics adaptor to use one of
the monitor’s preset display modes shown in
Table 1
on the next page. Other
graphics signals may be displayed poorly or not at all. Note that the LM740’s
preset modes correspond to VESA or Apple Macintosh standard graphics
signals for these resolutions. All recent models of graphics adaptor should be
able to support these modes. For the native resolution of 1280 x 1024 pixels,
for example, refresh rates of 60, 70 and 75 Hertz are supported.
With Windows 95, 98, ME, 2000 or XP you can change the refresh rate of the
graphics signal as follows:
1. Double
click
the
Display
icon in the control panel.
2. From
the
Display Properties
dialogue box, select the
Settings
tab and
click the
Advanced Properties
button.
3. For Windows 95, 98, and ME select the
Adapter
tab, for 2000 and XP
select the
Monitor
tab. The refresh rate selection field is located in the
centre, at the bottom of the dialogue box.
4. Choose a refresh rate that corresponds with one of the factory modes from
the table below.
5. Click
Apply
, and then
OK
twice.
