With the cost of large LCD monitors falling to affordable levels, the next hurdle was to be able to have three, four or more of them side-by-side on your desk and have fast, stable UNIX or Linux graphics support for them. That hurdle is now eliminated. With Summit HX Series X Window System graphics sub-system support, one can have about as many side-by-side monitors as your desk can hold, and still have full hardware acceleration for all monitor views. You can even have all monitors showing one "stretched desktop," with four, or five, or six, or even ten1600x1200 monitors, all hardware accelerated. All of the monitors can be in one single logical xscreen.

On the other hand, if you prefer each monitor to have its own xscreen, that is available in the HX Series, too. In fact, if you want some monitors to have their own xscreen, while at the same time have one or more single logic xscreens stretched across groupings of two, three or more monitors, that is available in the HX Series, too. Sort of a mix-and-match capability.

The standard Summit HX Series products can support up to four, up to eight, or up to sixteen monitors, depending upon the "Level" of capability licensed. For more than sixteen monitors, we handle the situation as a special, but the HX series is capable of supporting up to thirty-two monitors and up to 32,768 total pixel width. Since no one is likely to need sixteen or thirty-two monitors in a side-by-side configuration, the HX Series can handle about any rectangular arrangement of monitors, even if some monitors are "missing." For example, a 4x3 (four wide, three high) arrangement with monitors missing at, say, the two top corners, can be easily configured, and the cursor can be configured to avoid the "black holes." The cursor can also be configured to wrap or not when reaching the limits of a direction. Pretty amazing stuff. For Wall Display applications using the HX Series, check out the Wall Display page.

Some highlights are listed below. A Summit Manual is available in pdf form for download.

• Available in three "levels" - up to 4 monitors, up to 8 monitors, or up to 16 monitors
• Exceptionally high graphics performance
• Stable, trouble-free operation
• Support for both 32-bit and 64-bit x86 and SPARC running Linux or Solaris kernels

A limited number of cards are presently supported by the HX Series (see below), but more are in the pipeline as graphics chip documentation is made available and drivers are written. Although the Xentera cards from Colorgraphic have been discontinued, they are fully supported in HX, enabling the Windows-to-Linux conversions with systems using the Xentera cards to be easily switched to Linux (or Solars).
