REVIEW: ATEN’S 4K 2-PORT USB DISPLAYPORT KVM SWITCH

The newest addition to ATEN’s KVM line of products, the CS782DP, was released last month. Simply put, it’s a video control console that can connect two 4K computers to a DisplayPort, allowing you to switch control of the display (to either computer), while using the same keyboard and mouse for both.

Review: Nicole Boyd

This device is ideal for those who multitask between two computers at their workstation, each for different functions. For example, one may be a dedicated build for editing and VFX work, whilst the second machine is built for audio production. Or maybe you have a Mac for work and a PC for gaming.

Switching between computers is done with either your mouse, a hotkey, the (supplied) remote port selector, or automatically by powering on/off either machine. Also, it’s bus-powered, so no need for yet another plug taking up precious space on your power board.

In the past, I’ve always connected both my iMac and Windows machines to my monitor, via HDMI cables. But switching between them meant physically changing the display source, along with owning two sets of keyboards & mice, and umpteen ‘rechargeable’ batteries.

The money I’ve spent on ‘rechargeable’ batteries alone over the years could have fed a small nation, so I do like the idea of only needing a single keyboard & mouse.

Also, I can’t deny the novelty factor of switching between my computers by simply pressing a button (on the remote port selector) with an LED indicating which computer port is in use. I admit to toggling between both many more times than really necessary for this review.

So, I can see the convenience of using the KVM switch when multitasking on a project, it saves time messing with cables, changing display sources and moving keyboards and mice out of your way (and god forbid if the second mouse is out of batteries).

The console’s mouse ports can support any USB 2.0 peripheral and you can also connect a USB hub to it for multiple devices (you’ll need a powered hub for some peripherals).

The output on my iMac is capable of 4K resolution (I’m yet to buy the shiny new 5K iMac, that all the cool indie filmmakers have), and my Windows laptop is fairly new, so there was no issue with resolution changes when switching machines. Both looked crisp, the colour output was accurate and there was little lag when switching.

The KVM switch also supports MST (multi-stream transport) allowing multiple monitors to use a single DisplayPort, but to do so you’ll need an MST hub or monitors (and computers) capable of DisplayPort 1.2 daisy-chaining.

It’s important to mention here that the CS782Dp is is capable of resolutions up to 4K UHD (3840×2160) at 60Hz. So if you need to work in full DCI 4K (4096 x 2160) resolution for film festivals or cinematic projects, you’ll still need to connect your machine directly to your monitor.

Also, for those working in audio production, HD audio is supported (through the DisplayPort playback) but it is limited to only 2.1 surround channels.

The CS782DP comes with DisplayPort, USB and Audio cables (two of each) and the previously mentioned (and pressed many times) remote port selector.

FINAL THOUGHTS

For filmmakers and videographers creating content that will primarily be viewed online or for television, then the CS782DP can be a real convenience and time saver. It was easy to install and worked well.

But there are some limitations – it’s capable of 4K UHD but not the full DCI 4K and the audio output is limited to 2.1 channel surround.

    Hey Nicole, any chance you could post a quick video demonstrating the time it takes to switch between computers? Great review!
