Are LCD/Plasma/Smartphone monitors susceptible to EMR eavesdropping?
LCD has been shown to be susceptible to Tempest attacks at least http://www.omninerd.com/articles/TEMPEST_Attack_on_LCD - by listening on the signal that was transmitted in the wire to the monitor ... that might work on a plasma as well (but this might not work for like a TV if there are no cables that can leak information)
