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.
