Is it safe to hot-plug a DVI cable?
I was just wondering, and couldn't find relevant documentation, when attaching external display to (macbook air in my case, but should be same for all laptops?) laptop via DVI or VGA should computer be turned off? and turn on once monitor is attached? or is it safe to hotplug it when laptop is running?
if hotplug is ok, should I have ext monitor turned off, and turn it on once plug is in?
any thoughts on this?
or am I just thinking to much about these things? :)
