His X1550 256MB (512MB HyperMemory) PCIe x1 is a economical multi-monitoring solution for the Business and Multimedia. It hasa 4 pixels Shader units, a clock memory of 550 MHz and a core memory of 800 MHz. Each HIS X1550 PCIe x 1 card enable user to connect to 2 monitors at the same time and up p to 9 monitors can be connected. User can easily control the setting by the well-known ATI Catalyst driver.

The PCI-X1 slot on nearly all traditional motherboard. Users who need to deal with several applications in the same time, especially to professionals in multimedia field, found multi-montiors setting a huge time saver. The ability to display e-mail on one monitor, a browser window on a second and in some cases an application on a third, and then seamlessly move their cursors from screen to screen, is a clear benefit!

Having multiple monitors is more than just having more space. It can be a huge time saver for people!

Features Advantages

  • World's best performance PCIe x1 solution on ATI X1K family with Dual Link DVI supported
  • Multi-monitors possibility
  • Bringing upgrade possibility to those onboard graphic without PCIe x16 slot
  • Best for Video, Photo and Office applications
  • Low Profile form-factor

Upgrading Possibilities:

  • Brand name system: like Dell (eg: Dell Dimension E310), HP, IBM and some of those onboard graphic systems which do not come with extra PCIe x 16 slot but only with 1 or more PCIe x 1 slot(s). For example:
    • Dell E310.
    • Dell optiplex 745
    • Dell Optiplex GX520
    • Dell PowerEdge SC1430
    • HP/Compaq SFF desktop dc series(except dc5100 SFF)
  • Chipset limitation: such as Intel i910GL, i915PL/GL/GV, i945GZ come with PCIe x 1 but without PCIe x 16 support.
