The 2-Port VGA and USB Micro KVM is small in size but provides big box functionality. It supports video resolutions up to 2048 x 1536 while providing full keyboard and mouse emulation to prevent system lock-ups. With no software required, installation is hassle free; simply connect the cables and power up. Hot key functionality enables you to switch from PC to PC without ever taking your hands off your keyboard. The KVM's LEDs clearly indicate which system is selected.
