The ATEN CS1922 2-Port USB 3.0 4K DisplayPort KVMP Switch provides the latest innovations in desktop KVM switching technology for the increasing demand of higher video quality and transfer speeds on modern computers. The ATEN CS1922 offers an unprecedented performance of delivering 4K resolution, the next generation USB 3.1 Gen 1 hub with SuperSpeed 5 Gbps data transfer rates and enhanced user-friendly operations.

As a KVM switch, the CS1922 allows users to access two DisplayPort computers from a single USB keyboard, USB mouse and monitor console. Doing so with ease, the CS1922 provides three convenient switching methods - using front panel pushbuttons, mouse, or hotkeys for flexible access to any computer connected to the installation.

The unique independent switching feature allows the KVM control to focus on one computer while the USB peripheral focus is on another computer. This eliminates the need to purchase a separate USB hub or stand-alone peripheral sharer - such as a print server, modem splitter, etc.

With its rich feature set, the CS1922 is designed to surpass all requirements in graphic design, animation, and video-editing applications. Such as CAD/CAM (computer aided design/manufacturing). The CS1922 allows you to share the audio from each of the connected computers. HD audio transmitted by DisplayPort would offer you a different experience.

2-Port USB 3.0 4K DisplayPort KVMP Switch (Cables included) Application

Remarkable Audio/Video Experience

  • Superior video quality - 4K UHD (3840 x 2160 @ 60 Hz) and 4K DCI (4096 x 2160 @ 60 Hz)
  • DisplayPort 1.2 compliant, HDCP compliant
  • Supports HD audio through DisplayPort ***
  • Full bass response for high-quality 2.1 channel surround sound systems

Intelligent Operation

  • Computer selection via front panel pushbuttons, hotkeys, and mouse ****
  • Independent switching of KVM, USB hub, and Audio focus
  • Power On Detection - if a computer is powered off, the CS1922 automatically switches to the next powered-on computer
  • Auto Scan Mode for monitoring all computers

Versatile Compatibility

  • Keyboard emulation/bypass feature supports most gaming keyboards
  • Mouse emulation/bypass feature supports most mouse drivers and multifunction mice
  • Multi-platform support - Windows, Mac and Linux
  • Mac keyboard support and emulation*****
  • Multilingual keyboard mapping supports English, Japanese, French and German keyboards

* MST requires two monitors capable of DisplayPort 1.2 daisy-chaining, or use of a DisplayPort MST Hub. The PC source must be DisplayPort 1.2 compliant. A DisplayPort v1.1a display can be the last display in a DisplayPort v1.2 chain.
** DisplayPort Dual-Mode technology (DP++) does not require an active adapter for most single display setups.
     Active DisplayPort adapters are recommended if you are unsure of the video source's DP++ compatibility.
*** HD audio through DisplayPort cannot be switched independently.
**** Mouse port switching is only supported under mouse emulation mode with a USB 3-button mouse wheel.
***** PC keyboard combinations emulate Mac keyboards. Mac keyboards only work with their own operating system.

Question: Do you have any products that allow running 6 monitors (via MST Hub)? Potentially 2 display port outs, that could be daisy changed into 3 each?
Answer: Thank you for your inquiry,

DisplayPort 1.2 MST is limited to chaining up to 4 display at a resolution of 1080p. As far as I understand, this limitation is based on the total bandwidth of the DisplayPort 1.2 standard, and cannot be bypassed via MST.

If you are looking at a command center type application, the Adder CCS-PRO8 KM switch may be able to accomplish what you are hoping.

You could also use a KVM Over IP Switch and individually open each monitor as a source via the web ui.

Question: If I have a monitor that's running 3440x1440 at 100Hz refresh rate (34" UltraWide Gaming Monitor) with G-Sync enabled, will this switch be able to support that refresh rate, resolution, AND maintain the G-Sync functionality if I am running a DisplayPort cable from my gaming PC (with 2 graphics cards running in SLI that have G-Sync enabled) to the dock and from the dock to that 34" monitor? Thanks for your help!
Answer: Thank you for your inquiry,

Without G-Sync, 3440x1440 @ 100Hz would be fine; Since 3440x1440 @ 100Hz is the maximum bandwidth that DisplayPort 1.2 can support, according to Aten, compatibility would depend on how much overhead G-Sync on your video cards would require - "[we don't have] much case history with G-Sync beyond that to be any more specific." If it wouldn't work at 100Hz, it should at 60Hz for example.

Also note, the dock you are using must support full DisplayPort 1.2 standard including G-Sync passthrough.

Please let us know if there is anything else we can help you with!

Question: Does the CS1922 support three DisplayPort 1.2 displays from one DisplayPort 1.2 source? The Aten site specifically mentions "2" console displays. I'd like to confirm this KVM is only limited to the DisplayPort 1.2 spec which supports up to 4 compliant displays chained together.
Answer: Thank you for your inquiry,

The Aten CS1922 would indeed support the full DisplayPort 1.2 specification including (3) DisplayPort 1.2 displays chained from one DP 1.2 source.

See below for supported resolution for multiple MST monitors connected to the Aten CS1922:

Aten CS1922 Displayport MST - Triple-Monitor DisplayPort 1.2

1680 x 1050 (WSXGA)5
1920 x 1080 (1080p), or 1920 x 12004
2560 x 1600 (WQXGA) 2
3840 x 2160 (4K UHD), or 4096 x 2160 (4K DCI)1

Question: I have an HP EliteBook 840 G3 laptop and my desktop has as a GTX 1060 graphics with a bunch of display ports. I want to switch to four monitors. Is this the right product?
Answer: Thank you for your inquiry,

The Aten CS1922 should indeed be compatible with your application. If would like Dual-Display support for now or for the future you may also be interested in the Aten CS1942DP. Both models support full DisplayPort specification up to version 1.2, including resolutions up to 4K.
