Incorporating the latest Multi-Stream Transport (MST) technology, Aten CS1924M 4-Port USB 3.0 4K DisplayPort MST KVMP Switch is the world's first DisplayPort KVM switch with a built-in MST hub. The CS1924M enables users to adopt two console displays from a single DisplayPort 1.2 video source, providing an extended desktop mode and splitter mode at resolutions up to 4K for multitasking across two displays while reducing bulky cable connections.

To meet the ever-increasing demand for high-speed peripheral data transmissions, the CS1924M integrates a USB 3.1 Gen 1 hub to deliver unprecedented data transfer rates up to 5 Gbps - allowing you to maximize multitasking operations.

The unique independent switching feature allows the KVM switch's focus to be on one computer while its 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 or splitter. Additionally, the switch allows you to share the audio from each of the connected computers and even allows HD audio transmitted through a DisplayPort source.

With a rich feature set, the CS1924M is designed to exceed the requirements such as excellent video quality and ultra-fast data transmission speed for gaming, graphic design, animation, and video-editing applications.

Question: Does the Aten CS1924M support a 4th monitor?
Answer: Thank you for your inquiry,

Yes, MST chaining would allow you connect up to 5 displays to the CS1924M KVM switch.

See below for optimal resolution for multiple MST monitors:
Display Resolution with Standard 60 Frames per Second Refresh RateMaximum Number of Monitors Based on DisplayPort 1.2 Bandwidth
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

Please note, MST requires monitors capable of DisplayPort 1.2 daisychaining, 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.

Question: My question is, could I setup a macro on say a mouse button or a gamepad button for the default hotkey command? I went over the manual and saw that the default hotkey for switching between ports is Scroll lock twice, followed by the port number and Enter key.
Answer: Thank you for your inquiry,

We confirmed with ATEN Tech Support that It would not possible to do that. If using 'Scroll Lock' key conflicts with other programs running on the computer, the 'Ctrl' key can be used instead.

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

Question: I am interested in this model and wondering if its supports the following set up. Basic need is that each PC source needs to support dual monitors and the ports on PC's are Display Port 1.2a spec. Connectivity wise one DP port from monitor goes into DP console port on the KVM and another monitor HDMI to HDMI on switch? I also have a DAS Prime 13 keyboard which may have a USB hub in it and want to make sure that it can be used with this model.
Answer: Thank you for your inquiry,

Connectivity-wise, one DP 1.2 connection (per source computer) is split into one DP and one HDMI video output port for dual monitor local console access of the source computers. Note: The CS1924M uses DisplayPort MST technology to pull two video connections from a single DisplayPort 1.2 video cable; The CS1924M requires full MST (Multi-Steam-Transport) & DisplayPort 1.2 support for all the sources and the output devices (monitors and any possible adapters).

For a standard Dual-monitor DisplayPort to HDMI KVM switch without external HDMI adapters or MST requirement, you may also be interested in the SmartAVI DPN-4DUO.

As far as your keyboard goes, since the Das Keyboard Prime 13 appears to have separate USB connections for the Keyboard & Hub, you should be able connect the keyboard to a KVM switch that features USB Peripheral Device Hub ports, such as this CS1924M or the SmartAVI DPN-4DUO - Plug the Keyboard into the KVM Keyboard USB port, and the Keyboards USB Hub port into the KVM Switches USB Hub port. That being said, since the neither KVM switch explicitly states support for this model of the Das Keyboard, we are unable to guarantee compatibility - you may also want to contact Das Keyboard to see if they know of any compatibility issues with this model of keyboard and KVM switches.

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

Question: I am looking at this to run 3 monitors off a MST and 1 off the HDMI. In the package that includes the MST above does it support 2 or 3 monitors? Also, are the outputs of the MST HDMI or Displayport?
Answer: Thank you for your inquiry,

This switch should be perfect for your application. The Aten CS1924M has a built-in MST hub that splits the DisplayPort MST input stream into (1) HDMI + (1) DisplayPort MST video output. The DisplayPort MST video output can optionally be further split into up to 3 more video outputs (up to 5 total) via an external MST hub or via MST monitor chaining.

Note, all your PC sources must be DisplayPort 1.2 compliant to support this switch.

Because of bandwidth requirements, splitting MST multiple times changes the supported resolution; See below for maximum resolution for multiple MST monitors:
