CS1942 Manual (PDF)
The ATEN CS1942 further improves on previous KVM designs with the latest Mini-DisplayPort and Mini-TOSLINK connectors. These connections provide stunning digital video & digital audio capabilities in a KVM with reliable ultra-high resolutions, vivid picture quality, surround sound (with SPDIF connections), and support for 3D displays.
Please Note: The use of video adaptors may cause compatibility issues with the video component of the KVM.
The CS1942's independent switching allows the KVM focus to be on one computer while USB peripheral and audio focus are on the other. As a USB hub, it permits each computer to access connected peripherals on a one-computer-at-a-time basis, eliminating the need to purchase a separate hub. All keyboard and mouse data transfers via fast custom KVM cables for seamless response.
With its unique design and innovative features, the ATEN CS1942 provides style and superior functionality in any SOHO environment. The CS1942 is ideal for multimedia applications, gaming setups and multi-computer office environments - offering the ultimate space saving, streamlined KVM technology for any desktop.

Answer: Thank you for your inquiry. Unfortunately, to use the dual monitor capability of this KVM, you will need a video card that supports two monitors or two separate video cards. There must be an independent Mini DisplayPort connection, per attached target computer, per monitor in use.
Question: Does this DisplayPort KVM support display emulation (making a computer think the monitor is still there when the KVM has switched to another computer)? I am currently using a DisplayPort KVM from another manufacture and everytime I switch between computers the screen gets redrawn (windows get resized & stacked, desktop icons get moved, etc). I am using Windows 7.
Answer: Thank you for your inquiry. Yes, the CS1942 DisplayPort KVM has a form of display emulation. These switches use ATEN's "Video DynaSync" technology, which will store each monitors EDID information and pass it to the connected computers. The EDID information is maintained even when the computers and monitors are isolated from each other.
From ATEN, "Since a suitable EDID is always present for the computers, there is no "seeking" time lost when switching among multiple computers, no blank screen, and no need to reboot computers just to get them to detect the optimum video value. It's as though the computers each had a direct, full-time DDC connection to the monitor's EDID information."
Question: Does this KVM work with "Mini-DP to DVI" adapters, enabling one to use DVI monitors with this KVM?
Answer: Thank you for your inquiry. Unfortunately, no, this unit is not recommended for use with video adapters. They may cause compatibility issues.
Question: Will this support an Asus Swift/ROG PG278Q which is capable of 2560x1440@144Hz with 32bit color. Incidentally, the displayport1.2 spec permits a single display port to support more than one monitor (the feature is called multi-stream -- google it). I don't know if any Mac's support this but I would be a bit surprised to learn that later models don't.
Answer: Thank you for your inquiry. Unfortunately, according to the manufacturer, this device will only support resolutions of 2560 x 1600 @ 60Hz not 144Hz.
Thank you for mentioning the multi-stream. We have one of our manufacturers testing that functionality for us. It would be interesting to see how this Aten model handled daisy-chaining monitors.
Question: Can you confirm if this KVM maintains a USB connection when the device is switched. My current KVM from another company looses the USB connection to the alternative machine, this creates a noticible lag on the windows machine when i switch, and the mac machine logs me out when it cant find a keyboard.
Answer: Thank you for your inquiry,
Device lag during switching is a common issue with cheap budget KVMs. Higher quality and normal KVMs, like this Iogear CS1942, included a physical chip that constantly buffers / emulates the keyboard and mouse signals to each of the attached computers. This feature, usually called USB Emulation, prevents that lag in switching that you have been experiencing.
Question: Can I use a Mini DP to DP converter with this unit?
Answer: Thank you for your inquiry,
You can indeed use a Mini-DP to DP converter with the CS1942. You can also use a Mini-DP to DP cable such as the CAB-MDP2DPW-06MM (6ft) or the CAB-MDP2DPW-15MM (15ft).
If you would like a recommendation based on your setup, please feel free to contact your KVM Switches Online sales representative directly at 1-877-586-6654, at sales@kvm-switches-online.com, or via our online Chat functionality.
Question: Does this kvm work with dp version 1.2?
Answer: Thank you for your inquiry,
The Aten CS1942 features Mini-DisplayPort 1.1a, which is fully backward-compatible DisplayPort version 1.2.
