Belkin OmniView PRO3 USB & PS/2 4-Port KVM Switch - KVM switch - 4 ports

Advantages: Quick and easy to set up
Disadvantages: Video may get interference

...I've had this KVM switch for a number of years now, since my previous one only had two ports. I found this one fairly cheap somewhere. You're supplied with all the VGA and PS2 cables for each of the 4 connections. You can then plug these cables into your computers. The button on the top allows for quick switching. But as well as using the button for switching between computers, you are also able to use keyboard shortcuts. These are pretty common in KVM switches, and belkin manage to do it the same way as everyone else. Great for people that are already used to using a KVM switch. The KVM switch has a useful beep, which can be helpful to understand when a command was received by the switch. The switch also has a port for plugging in power. This helps improve the quality of the picture as there is more power behind it. Most of the time... Read review

Advantages: price, simplicity
Disadvantages: no USB keyboard/mouse connector

...This product does exxactly what it says on the tin. It lets you view and control two computers from one monitor, keyboard and mouse. It is PS2 only though and not USB - so if you have a very new PC without PS2 ports then this one is not for you - look on this site for one with USB connectors. Switching between machines is simple, just one key press to switch. One word of warning, if you plan to use this to just connect up the monitor cable and not use the keyboard and mouse connections (as I tried) it will not work as the device needs to collect power from all 4 connectors. With just 2 connected it suffers from lock ups. Tech Support soon helped me sort this out though ;) When connected as specified however it works perfectly!... Read review

Advantages: Can dispose of 3 monitors, keyboards and mice.
Disadvantages: Not future proof. USB only machines may not work.

...selected port, not just the adjacent one, would have been an improvement. [Hint: If there are two machines that are used most often or switched between frequently, plug these in to ports 1 and 3 (or 2 and 4). Two clicks will switch between these in either direction.] The other thing I would say is that my device at least does not like power cuts, producing a single high-pitched tone when power is restored until the Select button is pressed. A 4-way KVM will probably cost around £100 new plus I suspect that a lot of the new devices will be all USB connectors, which will needlessly occupy two of the USB ports on your PS/2 machine, which may only have 2 or 4 USB ports to begin with. Either find a USB to PS/2 adapter that works or choose the KVM depending on whether you are buying multiple new machines or intend to administer your existing... Read review
