### Features

#### World’s First DisplayPort KVM Switch with Built-in MST Hub

* One USB keyboard/mouse and DisplayPort or HDMI monitor control 4 computers and 2 USB peripherals
* Built-in Multi-Stream Transport (MST) hub allows dual displays (DisplayPort / HDMI) from a single DisplayPort source1
* Supports MST Mode, Splitter Mode, and Single Port Mode.
* 2-port USB 3.1 Gen 1 hub with SuperSpeed 5 Gbps data transfer speeds
* DisplayPort Dual-Mode (DP++) technology supports HDMI and DVI signals via a DisplayPort-to-HDMI/DVI DP++ adapter2
* Firmware upgradeable
* Hot pluggable – add or remove computers without powering down the switch

#### 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 1.3 compliant3
* Supports HD audio through DisplayPort4
* Full bass response for high-quality 2.1 channel surround sound systems

#### Intelligent Operation

* Computer selection via front panel pushbuttons, hotkeys, mouse5, and RS-232 commands
* Independent switching of KVM, USB hub, and Audio focus
* Power On Detection – if a computer is powered off, the CS1924M automatically switches to the next powered-on computer
* Auto Scan Mode for monitoring all computers

#### Versatile Compatibility

* Multi-platform support – Windows, Mac and Linux
* Multilingual keyboard mapping supports English, Japanese, French and German keyboards

{% hint style="info" %}
Note:

1. MST (Multi-Stream Transport) requires either monitors that are capable of DisplayPort 1.2 daisy-chaining, or use of a powered DisplayPort MST Hub. A DisplayPort v1.1a display can be the last display in a DisplayPort v1.2 chain. The PC source must be DisplayPort 1.2 compliant
2. 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.
3. For DisplayPort 1.4 compliant display device, make sure to configure the device setting to be compatible with DisplayPort 1.2 to avoid compatibility issue.
4. HD audio through DisplayPort cannot be switched independently.
5. Mouse port switching is only supported under mouse emulation mode with a USB 3-button mouse wheel.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.brwall.com/aten/kvm-products/desktop-kvm-switches/cs1924m.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
