D-Link DKVM-4
D-Link's entry into the KVM field is its DKVM-4. The DKVM-4 follows a more traditional KVM switch layout than the Linksys model, and it also comes with a power adapter to keep things running smoothly. Its all-metal case is supported by rubber feet to prevent the unit from being dragged around by sets of weighty cables, and everything seems solid enough. The cables needed to connect the DKVM-4 to your PCs, however, presented a bit of a problem. While both the Linksys and IOGear KVM switches use female monitor ports, the DKVM-4 is all male when it comes to monitors. This nonstandard approach is a bit disconcerting, since it limits the cables you can use. However, the required cables from D-Link are half the price of those required for the Linksys and IOGear. Price-wise, it's not so much of a bad thing after all.

Setup of the DKVM-4 is just as simple as with the Linksys ProConnect, though much cleaner because of its traditional KVM switch layout. With all but the controlling keyboard and mouse cables coming out of the back of the unit, the DKVM-4 fits unobtrusively on a desk, with its status LEDs and switch button easily accessible on its front edge.

All the usual bells and whistles are here: hotkeys, an audible cue when switching between PCs, and autoscan functionality. The DKVM-4 is on the lower end in terms of screen resolution, as it only supports 1600x1200. Unless you're running a massive monitor and are really greedy when it comes to desktop space, this limitation probably won't be an issue. However, it is worth mentioning as both the Linksys and IOGear units support up to 1920x1440.

All in all, the DKVM-4 is standard fare when it comes to KVM switches: it works, doesn't have any glaring problems or missing features, and isn't overly expensive. With no quirks or frills, the DKVM-4 is a solid entry.
