A 4-port 4K 60Hz HDMI KVM switch that works well with KDE Plasma


Please, I need someone to advise me of a 4-port KVM switch (that is, for 4 computers) with HDMI connections, that supports 4K resolution at 60Hz and most importantly, that works well with KDE Plasma.

I have tried with a couple of switches bought from Amazon but they are giving me many problems with KDE. With GNOME both work great, the computers that have GNOME can be changed in just 2 or 3 seconds, but those that have KDE when changing to them the screen stays black and does not react until you move the mouse after several seconds, so switching from one computer to another with KDE takes almost 15 or 20 seconds, which is inadmissible (it is as if it were not able to automatically detect the HDMI signal that comes from the KVM switch when the computer is activated on it, which GNOME does do correctly).
