Geminus brings multi-monitor support, screen rotation (for LCD panels that can be used in portrait modes), graphics acceleration and faster JPEG rendering to the IYONIX pc desktop.

Other features include the ability to transform/rotate JPEGs, which is available for all RISC OS machines, and Red/Blue colour swapping to support other graphics cards and digital outputs such as DVI (not yet supported by the NVidia driver module).

• Mult-monitor support. Install additional graphics card(s) in your IYONIX pc and expand your desktop to span multiple screens.
• Portrait modes. Create modes that can be used on a rotated LCD panel.
• Acceleration. Geminus makes more extensive use of the 2D graphics hardware present on the NVIDIA graphics card (either GeForce2 or GeForce5) as shipped with the IYONIX pc. It also uses the off-screen graphics memory to increase the performance of your desktop, cacheing window contents and sprites
• Faster JPEG rendering. Around 3 times faster than the JPEG decoding and rendering provided by RISC OS 5 on the IYONIX pc.
• Rotated/transformated JPEG plotting can be used in many applications. This is a feature that is not available in any version of RISC OS to date because the API was specified but never implemented.
• Red/Blue colour swapping is available in 32bpp modes but has not been properly finished and released as a feature. It is unlikely to be useful at present, and is of limited use since the DVI and composite outputs of the GeForce2 are still unsupported by the NVidia driver module.
