What I Look for in a 4 Port KVM Switch
When I shop for a 4 port KVM switch, I first think about how many computers I need to control and what kind of setup I already have. I make sure the switch supports my monitors, keyboard, mouse, and any other USB devices I want to share. I also check whether I need HDMI, DisplayPort, VGA, or a mix of connections, because choosing the wrong video port can create unnecessary hassle.
Video Quality and Resolution
For me, video quality is one of the most important factors. I always check the maximum resolution and refresh rate the KVM switch supports.

Some KVM switches are powered by USB, while others need an external adapter. I check this before purchasing because I prefer a setup that is stable and doesn’t cause power issues with connected devices. If I use power-hungry peripherals, I usually choose a powered model.
Desktop Space and Cable Management
I always think about where the switch will sit on my desk. A compact design helps keep my workspace neat. I also consider cable length and organization, because a good KVM switch should make my setup simpler, not more cluttered.
