The GT 2 Xentera cards use one ATI graphics chip and are supported in Summit LX, the desktop series, if only one card is used in a system. The LX Silver and Platinum drivers will support Xi Graphics' DualView feature that provides the ability to split the display image between two monitors.

Multiple Xentera GT cards in a system and Xentera cards that have two or four ATI graphics chips are supported by the Summit MX (Multi-head) and the SingleLogicalScreen HX Series. If there are more than four displays attached to a system, use MX Silver or Platinum (Silver is 2D only; Platinum includes OpenGL 3D). For the HX Series, there are three "Levels" of support in the Silver Edition - Level 1 supports up to four monitors in SLS; Level 2 supports up to 8 monitors in SLS, and Level 3 supports up to 16 monitors in SLS. With HX, not all monitors have to be covered by the same xscreen, so you can use multiple xscreens, some of which are "stretched" across multiple graphics chips, if you choose.

In MX Series, each ATI graphics chip on a Xentera card can display an image across two displays in a configuration we call "Single Logical Image" mode. A GT 4 card can drive two sets of such display pairs; the GT 8 can drive four such pairs. However, each pair have separate logical images It is not presently possible to have one Single Logical Screen ("SLS") that covers the displays of different pairs. That feature requires the use of the HX Series.

Xentera GT 4 or GT8 - Use a Summit MX (Multi-head) driver Silver for 2D image rendering, and Platinum if OpenGL is also needed, AND you are using two displays per graphics chip. If you are using only one display per graphics chip - in order to get a separate 'X screen' per display, for example, Bronze and Gold can be used up to a total of four displays per system. More than four displays, go to Silver and Platinum, respectively. For stretching 2D images across two or more graphics chips use the HX Series.
