Questions about this item

Which version of the BFKK 4-Port HDMI KVM Switch should I choose for four computers?

This single model provides four HDMI inputs and one output, so it handles exactly four PCs with one monitor, keyboard and mouse set.

What does the 4K@30Hz headline figure mean once the switch is connected?

It supports resolutions up to 4096x2160 at 30 Hz or 3840x2160 at 30 Hz, and will down-scale automatically for lower-resolution displays.

Which interface standard does the switch use and what does it cap in practice?

It uses HDMI for video and USB for peripheral sharing, limiting video to 30 Hz at 4K resolutions while passing keyboard, mouse and printer signals through the USB link.
