Very well designed KVM switch

I am upgrading my old 2 port KVM switch to this 4 port Cybex. The processing of this device is very high quality and obviously designed for tough use. Unlike my current one, it comes wireless. Only one power cable is included. I wish the monitor port had multiple inputs. Currently you must select either all DVI-I, all HDMI, or all DPP. However, not all systems ship with the same monitor connector. If the goal is to make the device thin, they can come with adapters to keep customers happy…

Pros
  • Annual trial
Cons
  • Quick start guide

It's nowhere near beyond the usual KVM switch. I've bought them before and they all don't support 4k video, don't have security built in, but for a simple switch you can't beat their price. You can get them to easily switch between two computers with one monitor turned on. That's a whole different category. Emerson KVM switches are built like a tank and come in a well-packaged box. Emerson KVM switches come in a variety of configurations depending on what monitor ports you use; HDMI or DVI or…

Pros
  • Regular price
Cons
  • Something different

layman's overview

What, where and why about KVM switches allows you to manage up to 4 computers with one (or two) monitors and 1 keyboard. To set up a switch, connect 4 or fewer computers to the switch. The monitor outputs connect to the ports on the back of the KVM switch, the keyboard and mouse inputs also connect, and so on. You may need special cables for all connections. The computers and switch are powered on, and if everything is properly connected, you should be able to switch between different computers

Pros
  • An absolute legend
Cons
  • Not bad, but...

Overkill for most, but an absolute beast for those who demand the best

KVM switches are great for data centers, repair shops, or anywhere there are more computers than monitors/input devices. They're usually a lot cheaper than this one, but it's not your typical KVM. First, it's a brown business box with no marketing fluff. People buy them because they're working with an experienced seller or doing their own research (if you're Revain, you'll end up with the latter). Inside is a no less serious contraption. The relatively compact device manages without any optical

Pros
  • Easy to use
Cons
  • Can't remember

Connectivity is key with this device and it is designed to ensure there is no crosstalk between input devices and to maintain the overall security of the network. In this context, we have a four-port DVI-I KVM switch that, in short, allows you to have one output monitor and four input sources. Suppose you have four computers, each with DVI-I outputs, and one monitor with its own DVI-I input. You need to connect four DVI-I computer ports to ports one through four on the KVM switch, then connect…

Pros
  • Cool product
Cons
  • Appearance

comparable to shooting mosquitoes with a 40mm cannon

I've seen KVM switches in my day but never anything like it! Cybex isn't kidding. This switch is not for the casual user or even the moderately serious user. This is an extremely reliable and dependable switch. To be clear, this is not a network switch. This device simply exists so that you can connect multiple computers to one monitor. I work on 2-3 IT consulting contracts at the same time, all with different company computers. I used to connect them all to separate monitors on my desk. Now I…

Pros
  • Great for me
Cons
  • Hard to remember but it was

Cyber​​Secure KVM is a good option for DVI-I video systems

This Cybex Secure KVM is just a rebranded version from Avocent/Emerson. These are some of the best KVM switches out there. All of these devices are reliable and very well made, with the consistent seal of quality. And this device is compatible with almost every version of computer operating systems. However, each model differs slightly in important respects. Depending on your needs, a quirk of one of these could be significantly better for your needs. This is designed to work with DVI-I…

  • Pretty packaging
