3 Hardware installation 3.1 i-Mode i-Mode provides user with Intel Sandy special features and power saving options when no 3D gaming is used. To use Lucid VIRTU solution in i-Mode, display must be always connected to Sandy Bridge motherboard video output. Note: Display can be also connected to IPG VGA output instead of IPG DVI output. 3.2 d-Mode d-Mode is provided for demanding 3D gamers to achieve uncompromised 3D performance of discrete GPU installed in the system. In this mode, Virtu allows user to utilize Intel special features such as trascoding, while display is connected to discrete GPU. Note: We recommend you use d-Mode for better 3D performance unless you use Intel Insider feature or the power saving i-Mode. If you use Lucid VIRTU solution with SLI / Crossfire feature, please select d-Mode. We recommend you use d-Mode for Lucid VIRTU solution if your graphics card is equipped with dual GPUs. To use Lucid VIRTU solution in d-Mode, display must be connected to discrete GPU installed in the system.
