Canon will be showcasing a prototype 30-inch 4K industrial video display at next week's NAB Show in Las Vegas, according to a statement released today. Detailed specs and pricing have yet to be unveiled, but with the monitor squarely targeted at filmography pros, we don't expect hobbyists and budget shoppers to be in the market for this one. Don't let the "prototype" description fool you, either: though we'll be seeing it in non-final form at NAB, the company hopes to commercialize a finalized version of the 4K display before the end of the year. The news comes as Canon is in the midst of a huge push to the ultra high-def format, having unveiled a number of 4K-capable cameras of late. This is one we'll be keeping an eye out for on the show floor, so expect a full report as part of our NAB coverage coming your way next week.
