Working with two PCs at one desk is inconvenient to use two sets of keyboards and mice. The two monitors also occupy a lot of space on the table. But an HDMI KVM switch can help you save space and cut down on redundant gear. Two PCs can share a keyboard and mouse and a monitor through this switch. This KVM switch is equivalent to a combination of an HDMI switch and a docking station. It comes with 4 USB 3.0 ports that can be used to connect external devices such as mouse, keyboard, printer, etc. Moreover, by connecting two PCs to one monitor through HDMI cables and the switcher, it is possible to quickly switch the picture of the two PCs by simply pressing "SELECT". Perhaps you will need to output the images from your laptops to your TV or a bigger monitor for watching a movie or having a meeting. The HDMI 2.1 port can support up to 8K@60Hz and 4K@120Hz. If your laptop can support 8K or 4K resolution, the switch can transfer 8K or 4K picture from the laptop to your TV or another monitor with no pressure. The package has included two USB 3.0 cables (Type A to Type C) and one USB 2.0 cable (Type A to Type C). You only need to prepare three HDMI cables, and it is recommended that using standard 8K HDMI cables (most 4K HDMI cables can only support refresh rates up to 4K@60Hz, but 8K HDMI cables can support up to 4K@120Hz/60Hz and 8K@60Hz refresh rates).
