Barco, the popular high-end projector company, has announced a new 46″ LCD for video-display walls. Sporting a surprisingly low WXGA (1366×768 px) resolution (although it claims 1080p support, presumably via rescaling) the real kicker on this display is the bezels: varying from 2.4mm to 4.3mm . The smallest bezels I’m aware of are half-inch (12.7mm), making these significantly smaller.
See video of a 4-panel construction after the break.

NEC and Samsung also have monitors with “ultra-thin” bezels intended for display walls.
