ATEN CS1942DP Reviews

Does the job, but not without issues

By Rob

First up, the pros: this product does what it says. It provides dual-monitor KVM switching for DisplayPort monitors and USB 3.0. I've got two 4K monitors attached, and there's no issue with the signal getting to them. Also, unlike most alternatives, there are plenty of USB ports for sharing not just a keyboard & mouse, but also other USB 3.0 peripherals. The device itself is also well-constructed, feeling quite sturdy, and it comes with all the connecting cables you could possibly need. Technically it does what it's supposed to do, but honestly I'm a bit disappointed, especially for something so expensive. I bought this in the hopes that it would be easier than individually switching the inputs on my 2 monitors between PCs and using a separate USB switch to pass peripherals back and forth. It does do that, but with some quirks. The biggest one for me is that, instead of both computers seeing 2 displays connected and the box simply switching between which gets fed to the actual displays, whenever you switch away from one computer, it's as if you're physically unplugging the cable. In practice, this means whenever you switch back, it's like plugging in a new pair of monitors and Windows will reset the positions/sizes of all your programs, which is annoying. I've only been using this a short while, and it worked fine at first when switching, but I quickly encountered an issue where one of the PCs would just refuse to recognize the internal USB hub of the KVM after switching, and wouldn't recognize it until I rebooted that computer (unplugging/re-plugging all USB connections had no effect). I'm not sure if this will be a recurring issue, or was a one-off glitch. Also, this does offer some flexibility in what's getting switched. You can switch everything (video/audio/USB), or you can switch just video, just audio, or just USB. Unfortunately, there's no option to split the displays between the 2 attached computers, in the event that you want a side-by-side. Overall, this does what it says it will do, but it ended up not being as hassle-free and flexible as I was hoping it would be. It's not bad enough that I want to return it, but I probably wouldn't buy it again, not at this price.

Great KVM for dual [email protected] monitors

I work for a company that provides a company issued laptop that is locked down heavily. I have a my desktop sharing the same space at home with 4K monitors running at 60 Hz. So this in and of itself limits the options of KVMs greatly. I looked at a few others that either didn't offer and more benefits for the increase in price, or didnt work with my equipment. Note that KVM switches can have a lot of peculiarities so reach out to the vendor with you list of equipment ahead of time to save some trial and error. All in all, it works well and consistently with a few tweaks and gotchas: 1. This is due to display port technology, the screen will rearrange when you switch. This is due to DP being plug and play so your windows will get rearranged. I believe that there are some ways to fix this with an app that will automatically rearrange your windows. Also you can hard code in the EDID in a config file, which I will test at some point on my desktop. 2. Logitech Unifying receiver equipment does not work fully with the KVM commands. If you plug it into the keyboard USB port, the special features of the Logitech gear are no longer usable. If you plug it into one of the typical ports, you cannot use the keyboard commands to control the KVM, biggest loss here is the ability to switch between sources without having to press the physical button on the KVM. My solution to this was to get a one key keyboard from Techkeys that I am using for the sole purpose of switching the KVM since I have it mounted behind my desk. 3. I had to disable the auto detect source function. I am using a Surface Dock 2 and when auto detect was running it would not stay on the source when i was connecting it causing issues. I was able to switch back, but 50% of the time one of the monitors would not be working. One I disabled the feature on the KVM I have not had issues. 4. There is only one high speed USB port on the back of the KVM to connect to peripherals. I already had a hub but there were not enough ports. I needed to get another hub, after which I realized that I was having power issues running everything off of one port. So I got a powered USB hub with more ports and all is well again. Would be nice if it had more than one high speed USB port, but this seems to be common to KVMs. So just plan on buying a powered USB hub. In summary it works well for what I am doing with the only caveat left is the window rearrangement. The Connectpro UDP2-12AP-KIT seems to have all the features I was hoping for, however when I reached out them they said there were issues with the Surface Dock so that ruled it out, leaving the Aten as the best fit.

Simply flawless

I have used Aten KVMs for years. Whenever I am looking for one for another purpose or to match upgraded equipment, I always end up buying another Aten. This KVM doesn't disappoint. Are you stuck working from home? Do you have a sweet home computer with multiple DisplayPort monitors? Do you want to be able to use that same setup with a work computer or laptop? If you answered yes to those questions, this is the KVM for you. I bought this for my wife so she can use her dual monitor setup with work and home computers. She love s it. I have the 4 port version for myself, since I have a couple other computers to manage. Simply put, these KVMs just work.

Unlike many KVMs, this thing actually does what it says it can. I'm running two 4K monitors at 60Hz with absolutely no stability issues between a Mac and an Ubuntu machine. Will definitely go for another ATEN box if my needs change.

Good, but not perfect

I bought this KVM switch to share my monitors and peripherals between my personal computer and my work computer when working from home. My original plan was to use a DisplayPort MST hub to drive both of my 1920x1200 monitors from one of the ports and my 4k monitor from the other. This worked flawlessly in Windows, but it turns out macOS doesn't support MST. I can't fault this switch for that, but it's something to be aware of. My only real complaint about this product is its display emulation. It works perfectly when I switch away from a computer; all of my windows stay where I left them. The problem is that when I switch back to that computer, all of the monitors reconnect and all of my windows get shuffled around. I'm not sure if this is an unavoidable issue with DisplayPort or what, but it's a bit of a nuisance.
