- What is the latest firmware version for the SB-TB4K please? fwupd shows 44.c3 on mine;
 - Average monitor switching time using the SB-TB4K is 22s(!) for two 4K monitors in my experience, which is far from ideal. Does anyone have a better experience?
 

@Aqualung This depends on the hosts and hardware, by which the signal sent must be responded to in a timely fashion. For some hardware this delay will be higher than for others.
