I have a setup where I am using one external monitor (Dell P2414H) for two laptops - one Macbook Pro and one Dell Latitude E6430.
The dell is connected via a docking station with VGA cable, and I am able to use the USB keyboard and mouse when they are plugged in to the monitor. The Macbook Pro is connected directly to the monitor using a DVI cable and the Mini DisplayPort / DVI adaptor.
However, my MBP doesn't seem to see the external keyboard and mouse unless I unplug them from the monitor and plug them directly into the laptop. I need to switch between both laptops very frequently, so replugging is not a good option.
How can I make my MBP see the mouse and keyboard when they are plugged into the monitor?
