Using Dual View mode 83
Limits on Video Driver while using Dual View mode
1. Certain combinations of display modes, color depth and refresh rate, when
Dual View mode is active, are not supported because of video memory
bandwidth limitation.
2. When using Dual 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 Dual 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 Dual View mode can not support the VGA mode.
5. The video memory uses one memory pool for two screen and Direct Draw
application on Dual View mode in Windows 98. So activating the Direct Draw
application which does not support that mode could cause fail in changing
mode.
6. The program which does not have Dual View compatibility can not be used in
the secondary monitor on Dual View mode.
7. The ATI video driver supports VPE (Microsoft video port specification) for
multimedia function. So the program uses VPM (Cirrus logic video port
specification) may not be supported.
8. Changing Dual View mode to Single View mode while you maximize the
window of a program (such as Windows Explorer) could be failed. Set the
resolution of the secondary monitor lower than the primary monitor, or adjust
the window size to smaller (not full screen).
9. When you use CRT and TV together as the same primary monitor or secondary
monitor, the display size of the CRT is smaller than TV. The reason is that the
frequency bandwidth is different from TV to CRT.
