[QUOTE="pwatts, post: 923725, member: 146"] The spec allows hot-plug in principle. In reality, potential differences between different devices due to isolated power supplies can cause failure even though ground equilibrium should be established by the grounded shell making first contact. The other cause of blown HDMI of course is good old lightning especially when satellite dishes are in the picture. If you have no satellite inputs and there is a solid ground connection between the devices you want to connect/disconnect (earthed connection to the chassis can do that) you should be OK to hot plug, but even then ESD remains a (small) potential risk. Reminds me of a saying we have at work: the answer to whether something is hot pluggable is mostly dependent on the value of the devices and how much of a rush you're in :flame: [/QUOTE]
