I've been tasked to find such a device for work, but given an insufficient budget ($800 max). I know a projector-based unit is right out, so I'm leaning toward an interactive (i.e. touchscreen) monitor in the 55" class. I've found a couple at about 3x budget from Dell and LG, and am wondering if anyone out there knows of better options. Key wants:
55" or so (small conference room)
1080p minimum
USB/HDMI/DP inputs
Of course, if it accepted input from a Roku or similar streamer, no one in my office would complain.
