What is a VGA KVM switch?
A VGA KVM switch is a device that allows multiple computers to share a VGA monitor, keyboard and mouse. Its full name is Video Graphics Array Keyboard Video Mouse Switcher, that is, Video Graphics Array Keyboard Video Mouse Switcher. Some VGA KVM switches also support 3.5mm audio synchronous switching to realize the sharing of earphones or speakers. Take the eKL-41U with 4 inputs and 1 output as an example for everyone to explain.
The principle of the VGA KVM switch is to switch the VGA, keyboard and mouse signals of different computers to the same monitor, keyboard and mouse through the built-in electronic switch, so as to realize the control and management of multiple computers. This principle can effectively solve the connection problem between multiple computers and a single display, keyboard and mouse, and improve the utilization and efficiency of the equipment.
VGA KVM switch has the following advantages
01、Save space and costs. If there are multiple computers but only one monitor, a VGA KVM switch can be used to reduce device usage and avoid repeated purchases and installations.
02、Improve efficiency and safety. If there are multiple computers that require frequent switching operations, you can use a VGA KVM switch to quickly switch between different computers without the need to unplug or restart the system, reducing the risk of faults and data loss.
03、Supports multiple platforms and resolutions. The VGA KVM switch can support various brands of computers and servers such as PC, SUN, and MAC, and is suitable for operating systems such as DOS, NET, WIN95/98/2000/ME/XP/NT, UNIX, Linux, and more. The VGA KVM switch can also be adapted to various resolution displays such as VGA, SVGA, and XGA, theoretically supporting up to 2048 × The resolution of 1536 60Hz, but the specific supported resolution depends on the actual resolution supported by the VGA KVM switch.
