Macbook freezes every few seconds when monitor input is switched I have a macbook pro running 10.11.5 El Capitan.  I have it connected to two external monitors -- one using HDMI, and the other using thunderbolt to HDMI.  These two monitors are also connected to another computer using DVI cables.  I'm also using the audio output jack for the macbook.  When I switch the monitor to use the DVI input for the other computer, several things happen on my macbook


The mouse and keyboard input freezes for about 3-5 seconds every 3-5 seconds.
Video freezes intermittently, roughly corresponding with the mouse and keyboard freezes.
Audio works fine without any freezes until I switch the monitor back to the HDMI input for the macbook, then it is completely muted and the volume control is greyed out until I unplug and replug in the external audio jack.


Is there a way for me to share a monitor with another computer without having these freezing problems?  I would like to avoid having to disconnect and reconnect cables unnecessarily.
This happens on just about every computer when you are adding or subtracting output monitors. I suppose it has to do with how the(in this case internal) GPU processes the new output. 2 extra monitors is also a big feat for a Macbook's GPU!

The only way I am aware of achieving what you want would be through remote desktop. However that has it's own caveats as I'm sure you already know.
