Sharp

Apple briefly posted a Sharp 4K monitor for sale on its European online stores, then removed it. Could this herald 4K displays from Apple?

On Friday, IDG News Service and other Apple blogs posted news about a Sharp 4K display for sale on Apple's European online stores.

Then -- as of Sunday night Pacific Time -- Apple removed the display, as MacRumors pointed out.

The phantom Sharp display is the 32-inch PN-K321.

Its specs include a 3,840x2,160 4K Ultra HD screen based on Sharp's IGZO technology, 1.07 billion color palette, 350 cd/m2 brightness; and a 800:1 contrast ratio.

Apple's new Retina MacBook Pros are able to support a 4K monitor and the upcoming Mac Pro can handle three 4K displays.

The new Mac Pro has fueled speculation that Apple will have to meet the need from professionals for an ultra-high-resolution display.

Apple's current 27-inch Thunderbolt display is good for resolutions up to 2,560x1,440 pixels.

This development follows Dell's introduction of a 24-inch 4K display that will retail for $3,499.
