Touch and Teach
Teaching turns into interactive education with a touch monitor, like NEC’s V423-TM display. The 42-inch display can not only show full HD programming, but it has cameras at each corner that respond to four individual touch inputs, so two can use the screen at once. The screen has inputs for DVI-D, HDMI and DisplayPort as well as an RJ-45 networking port and can use video processing boards that use the Open Pluggable Specification. The V423-TM will sell for $2,399 with a three-year warranty.
