Question: Does this Device allow for the use of a thunderbolt 3 to DP adapter before the Switch and a DP to DVI adapter after the Switch? Are there any known compatibility issues with these conversions?
Answer: Thank you for your inquiry,

According to the CS1942DP product development team "Using converters with DisplayPort is sketchy at best. The ones listed (DP to DVI, and Thunderbolt 3 to DP) are ones I wouldn't instantly rule out, but I wouldn't be surprised if there were problems either."

Adapting from 'data cables' type video cables like DisplayPort or Thunderbolt depends a little on the many ways a vendor can implement parts of the 'data cable' specification, so certain adapter implementations may cause issues with a KVM.

We have generally heard of less issues with adapting to and from HDMI or DVI instead, with something similar like the SmartAVI UHDN-4P-DUO 4-Port 4K Dual-head HDMI KVM Switch or the Adder AV4PRO-DVI-Dual 4-Port 2K Dual-head DVI KVM Switch.

Please note, when adapting from Thunderbolt 3, you will some Thunderbolt capabilities. You can switch between machines video and keyboard / mouse, but you will not retain Thunderbolt-based features like the "daisy-chain" capability.

Question: Does the CS1942DP support 4K 60Hz RGB(YCbCr 4:4:4) 10-bit?
Answer: Thank you for your inquiry,

Yes it does. The Aten CS1942DP supports the full DisplayPort 1.2 spec, including 4K 60Hz RGB (YCbCr 4:4:4) 10-bit.

Question: Can audio be passed through the USB cable connecting the two PCs to the KVM as opposed to the 3.5 mm stereo jack?
Answer: Thank you for your inquiry,

Audio can indeed be passed through the CS1942DP USB peripheral hub device ports instead of the 3.5 mm jack, but there will be a slight delay between port switches as the KVM connects the USB peripheral devices to the newly focused PC and it loads the appropriate drivers. This is possible with KVM switches that feature USB peripheral hub ports in general, and is a fairly common application.

Question: Does this device support Nvidia Gsync?
Answer: Thank you for your inquiry,

It does - The Aten CS1942DP supports the full DisplayPort 1.2 specification, including G-Sync support.

Question: Does the CS1942 support 1440p@144hz through DisplayPort?
Answer: Thank you for your inquiry,

It does. The Aten CS1942DP supports the full DisplayPort 1.2 standard, including 1440p (2560x1440) @144Hz resolution.

Resolution & refresh-rate for the CS1942DP is only limited by the data-rate / bandwidth of the video stream - DisplayPort 1.2 can carry up to 17.28Gbps. Refer to this table on Wikipedia for all resolutions supported by the DisplayPort 1.2 specification.

Question: Hi there, when two CPUs are connected, does it disconnect the non-selected monitor? For example a laptop and a desktop screens are connected to the KVM. When on the desktop, will it move all the icons on the laptop as if a screen is disconnected, or does it stay online while the other is selected?
Answer: Thank you for your inquiry,

Local DisplayPort-based KVM switches (DP in and out), like this Aten CS1942DP, currently don't typically really feature EDID video emulation. This is because DisplayPort is a data-type cable instead of a video-type, and device vendors often implement the standard differently. As far as icons being reset because of resolution change / dropped devices, while this shouldn't happen in most applications, this is a known issue with certain operating systems and KVM Switches without emulation.

That being said, Networked KVM-over-IP Switches with DisplayPort video input usually keep the video sources awake. Or alternatively, we do offer some DisplayPort-to-HDMI KVM Switches that do support emulation to the display, like the similar SmartAVI D2H-4P. KVM switches based on other video standards, such as HDMI-based KVM Switches, also commonly feature EDID emulation.

Question: Does the CS1942DP allow the systems to be able to detect the monitors that they are using? For example, two ASUS monitors that support 1080p @ 144hz, would both systems be able to detect the monitor including the model used?
Answer: Thank you for your inquiry,

The monitors EDID information is handled solely by the Display Port protocol; the CS1942DP KVM is hands off. As long as everything is native DP (without any video adapters), there shouldn't any be change in how the monitor is detected.
