Update: The monitor doesn’t actually cost $2,499—that is the Australian price. In the U.S., the monitor will be shipping for a much more reasonable $1,399.
LG Electronics on Tuesday unveiled its new 31-inch Digital Cinema 4K monitor (4096×2160 px) for $1,399. Apple users will be pleased to hear that the monitor is compatible with both Mac and Thunderbolt. The monitor includes a Mini DisplayPort (in addition to 2 HDMI ports and 1 DisplayPort), which uses the same physical port as Thunderbolt enabling Mac users to drive the 4K display over a single Mini DisplayPort 1.2 cable.
