Question: I'm wondering if the Aten CS1944DP, or any of the DisplayPort dual display switches you carry, support DisplayPort 1.2's higher refresh rates, such as 2560x1440 at 144 Hz. I haven't quite been able to figure out whether any of these switches do direct DisplayPort passthrough (which I'd imagine would support all DisplayPort modes), or process the video signal (in which case I'd expect 144 Hz to not be supported). Thank you for any insight you might be able to provide!
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.

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.
