The ATEN CS1944DP desktop KVM switch helps organize your desktop. Especially when managing a multimedia workstation at a large organization, CS1944DP provides you with instant access to four computers, all through a single USB keyboard, USB mouse and two DisplayPort monitors.
Advanced video support provides a better-defined DisplayPort connection with video resolutions up to 4K (4096 x 2160 / 3840 x 2160 @ 60 Hz). Incorporating dual display capability, you are allowed to enjoy a wider screen and easily switch between four DisplayPort systems. In addition, featuring a built-in USB 3.1 Gen 1 hub, the CS1944DP delivers unprecedented data transfer rates up to 5 Gbps, allowing you to maximize multimedia operations.
Engineered to meet the ever-increasing demand for dual display, ultra-fast data transmission rates, and lossless 4K video resolution, the CS1944DP is specifically designed for where multitasking is needed such as design, financial trading, and video post production.
Please note: ATEN DisplayPort KVM devices will only support computers that have a native DisplayPort output. Using any sort of adapter, convertor, or docking station may prevent the EDID information from passing through.

Multi-Monitor via DisplayPort 1.2 MST (Multi-Stream-Transport)
MST allows you to use one or multiple monitors (Dual, Triple, Quad, 5-Monitor) to view video content in various ways. The optimum resolution for monitors in MST mode depends on the bandwidth shared between the displays.
| Display Resolution with Standard 60 Frames per Second Refresh Rate | Maximum Number of Monitors Based on DisplayPort 1.2 Bandwidth |
|---|---|
| 1680 x 1050 (WSXGA) | 5 |
| 1920 x 1080 (1080p), or 1920 x 1200 | 4 |
| 2560 x 1600 (WQXGA) | 2 |
| 3840 x 2160 (4K UHD), or 4096 x 2160 (4K DCI) | 1 |

Answer: Thank you for your inquiry,
This Aten CS1944DP Dual-monitor DisplayPort KVM should indeed support 2560x1440 @ 144Hz resolutions for each display. According to the vendor, this 4-port model and the 2-port model both support the full DisplayPort 1.2 specification including the higher refresh rates.

Question: Curious whether this switch can be made to support a Macbook Pro 15" with USB-C via adapter, in the closed lid mode, along with 2 desktop PCs.
Answer: Thank you for your inquiry,
The Macbook will need wall power connected to work with the lid closed. According to the original product development team, as long as you are able test the setup with the monitors and kb/mouse directly connected without the KVM and it works, the CS1944DP KVM will most likely work as well.
Also please note, if you are using a 'dock', sometimes docks can be problematic in general with DP KVMs.

Question: I'm wondering if the CS1944DP support Macbook pro with Thunderbolt 3 dock?
Answer: Thank you for your inquiry. According to the manufacturer, if the device has DisplayPort output, it should be supported, but once the output becomes DisplayPort, no further Thunderbolt functionality is available further down the line.
Please note, computer docks themselves can sometimes cause issues with DisplayPort KVM switches.
Question: Can you provide the length of the DP, USB, and audio cables please? And will this work with an HDMI to DP active converter? Thank you.
Answer: Thank you for your inquiry. According to the manufacturer, the length of the cables is 6'. They also stated that the device would not work with an HDMI to DP active converter, but could operate with a DP to HDMI adapter for the display.
Question: Does the CS1944DP support 4K 60Hz RGB (YCbCr 4:4:4) 10-bit?
Answer: Thank you for your inquiry,
Yes it does. The Aten CS1944DP supports the full DisplayPort 1.2 spec, including 4K 60Hz RGB(YCbCr 4:4:4) 10-bit.
Please let us know if there is anything else we can help you with!
Question: Does this support EDID emulation so that the connected computers do not know that the monitors are disconnected when it is not selected?
Answer: Thank you for your inquiry,
Local DisplayPort-based KVM switches (DP in and out), don't currently really feature EDID video emulation. Some DisplayPort to HDMI KVM Switches, like the SmartAVI D2H-4P-Duo, do however feature display-side emulation. A lot of DisplayPort-based KVM-Over-IP Switches also keep the sources awake (similar effect to EDID emulation).
KVMs based on other video standards, such as HDMI or DVI-based KVM Switches, also commonly feature EDID emulation.

Question: What is the purpose of dual DP input? I am looking at the Aten CS1944DP and it has two DP inputs per system. Why is that?
Answer: Thank you for your inquiry,
The Dual DisplayPort input and output allows the CS1944DP to switch between Dual-Monitor DisplayPort computer systems. This allows you to control multiple single or dual-monitor computer systems at your KVM user station.
Please let us know if there is anything else we can ever help you with.
