The Extron SW4 DVI A is a four input single link DVI switcher that allows multiple DVI input signals to be switched to one compatible display. It is compatible with PC resolutions up to 1920x1200, and also supports HDTV 1080p/60. To enhance and simplify integration, the SW4 DVI A features EDID MinderĀ® that automatically manages the EDID information between the digital display device connected to the output and all the input sources. By maintaining continuous EDID communication with all sources, EDID MinderĀ® ensures all DVI sources power up properly and maintain their video outputs whether or not they are actively connected to the digital display device through the switcher's output. Front panel LED signal presence indicators provides a quick means of active signal verification.

Selectable cable equalization for each input reduces the need for additional signal conditioning equipment by compensating for signal loss when using long input cable assemblies. Front panel switches allow user-selectable EQ levels. The SW4 DVI A is user-configurable for manual or autoswitching modes. Auto-input switching allows any input of the switcher to be selected automatically when the switcher detects a signal.

Convenient control options allow easy integration into a variety of environments, and include front panel control, IR, RS-232, and auto-input switching. To further simplify integration, the SW4 DVI A is housed in a compact, 1U, half rack width enclosure that is easily mounted into an optional Extron 1U Universal Rack Shelf Kit.


Note: The SW2 DVI A, part # 60-840-01, has been retired. The suggested product replacement is the SW2 DVI A Plus, part # 60-964-21.
