The *Display* page contains settings related to the emulated machine's 2D and 3D video cards.

Video
-----

Video card to emulate. Only cards supported by the machine's expansion buses will be listed. On machines equipped with an onboard video chip, the *Internal* option enables the onboard video.

The *Configure* button opens a new window with settings specific to the selected video card, such as the amount of installed video memory.

Voodoo Graphics
---------------

Emulate a **3dfx Voodoo** 3D accelerator, connected to the PCI bus and to the video card selected above.

The *Configure* button provides the following settings:

* **Voodoo type:** type of Voodoo card to emulate.

   * **Voodoo Graphics:** the original Voodoo model, with a single Texture Mapping Unit operating at 50 MHz.
   * **Obsidian SB50 + Amethyst:** a variant of the Voodoo Graphics, with two Texture Mapping Units operating at 50 MHz.
   * **Voodoo 2:** the second Voodoo model, with two Texture Mapping Units operating at 90 MHz, as well as SLI support.

* **Framebuffer memory size** / **Texture memory size**: amount of video memory to give the Frame Buffer Interface and Texture Mapping Unit(s), respectively.
* **Bilinear filtering:** apply bilinear filtering to smooth out textures displayed on the screen.
* **Screen Filter:** apply a filter to make the screen picture resemble the DAC (digital-to-analog converter) output of a real Voodoo card.
* **Render threads:** allows the Voodoo workload to be split into multiple CPU threads. 2 render threads are recommended for host systems with more than two CPU cores.
* **SLI:** add a second Voodoo 2 card to the system, connected to the first one through Scan Line Interleave (SLI).
* **Recompiler:** enable the Voodoo recompiler for faster emulation.

.. note:: The Voodoo recompiler requires a host CPU with SSE2 support. SSE2 is present in most CPUs released since 2005.
