96 Using Duo View mode
Table 9. Using several display devices
C = Coprocessor mode only
E = No Expansion
O = No Overlay
R = Same Refresh rate
The same CRT controller can not be used for both LCD and
TV.
Basically, the program should be started in the primary
monitor, then you can drag the program to the secondary
monitor to use. But, some programs are not able to drag from
the primary monitor to secondary monitor.
The order of Icons on the Windows desktop could be changed
after using Duo View mode.
Limits on Video Driver while using Duo View mode
1. Certain combinations of display modes, color depth and refresh rate, when Duo
View mode is active, are not supported because of video memory bandwidth
limitation.
2. When using Duo View in simultaneous display mode, frame rates in Direct
Draw applications are slightly lower because of the need to synchronize buffer
flip.
3. If the primary/secondary monitor on Duo View mode is set to high resolution
and high refresh rate display mode, the full frame rate setting on DVD-ROM
may not played properly. Playing DVD-ROM on Single View mode is highly
recommended.
4. It is not possible to use 16 bit colors in Windows 98. If so, secondary monitor
on Duo View mode can not support the VGA mode.
