Dual-Link DVI KVM for two computers

The ATEN CS1782A is a 2-port DVI Dual Link KVM switch with USB peripheral and audio support. It lets one keyboard, one DVI monitor and one mouse control two computers. USB Type A console ports connect the keyboard and mouse, while the DVI-I port carries the video signal. Front and rear audio jacks handle line-out, line-in and side or rear speaker channels.

Two-system setups needing DVI and analog audio

Suits operators who switch between two DVI-equipped workstations and require stereo or multi-channel analog audio routing. Not for users whose displays only offer HDMI, DisplayPort or VGA unless active adapters are used. Not for environments that demand more than two computer ports or digital audio extraction.

Maximum dual-link resolution 2560x1600

The console monitor connector supports DVI-D Dual Link up to 2560x1600 and Single Link up to 1920x1200. This resolution ceiling determines whether the switch can drive a given panel at its native pixel count without scaling or bandwidth reduction.

Questions about this item

Does the ATEN CS1782A produce audible fan noise or noticeable heat when switching between two computers all day?

The CS1782A has no fan and draws minimal power, so it runs silently; its operating range is 0 to 50 °C and the compact 2.2 × 10.1 × 3.5 in chassis stays cool during continuous use.

Which cables must I already own to connect two PCs and one DVI monitor to this KVM?

You need two DVI-D dual-link cables for video, two USB Type-A to Type-B cables for keyboard and mouse, plus any 3.5 mm audio cables if you want line-out or microphone switching.

Will my older single-link DVI monitor at 1920×1200 work reliably with the CS1782A alongside a newer dual-link display?

Yes, the switch supports both DVI-D dual-link up to 2560×1600 and single-link up to 1920×1200, so an older 1920×1200 monitor will operate correctly on the shared console port.
