Details

Features

* provides screen modes which span multiple graphics cards, allowing the desktop to be used across two or more screens
* supports up to 8 screens (Note: only 3 PCI slots are available for graphics cards in current IYONIX pcs.)
* screens can be arranged in any configuration (left to right horizontally, right to left horizontally, vertically..)
* each screen image can be rotated 90 degrees clockwise or anti-clockwise, allowing rotatable LCD panels to be used in portrait mode
* API allows applications to create their own display surfaces (the desktop is just one display surface) and thus claim screens for their own, exclusive use, either drawing to them directly or via the OS VDU drivers.

For example, Cino will be able to take over the second screen for DVD Playback, whilst the desktop is displayed in the first screen
* makes full use of the hardware acceleration already available in RISC OS 5 on all screens, plus a hardware DMA channel to improve scrolling and copying between screens
* graphical Configuration plug-in allows you to define your own large screen modes, specifying the screen positions and, optionally, rotations for each mode.
