Apple has introduced a new 30-inch Apple Cinema HD display, a new flat panel screen that features 2,560-x-1,600 pixel resolution. Apple also introduced new 23-inch and 20-inch displays to replace their existing flat panel monitors.

The new displays all have the by-now familiar widescreen aspect ratio found across almost all of Apple's pro hardware line, and sport dual FireWire 400 and USB 2.0 ports, and use DVI to connect to video cards instead of Apple's vaunted ADC interface -- making the new monitors compatible out-of-the-box with Power Macs, PowerBooks, and PC-compatible computers as well.

The new monitors feature a new aluminium design created to complement the industrial look of Apple's pro hardware, consistent with the theme first introduced when the Power Mac G5 hit the stage a year ago. A thin bezel is suspended by an aluminium stand equipped with an adjustable hinge.

What's more, the new displays can be mounted on walls or articulated stands that comply with the Video Electronics Standards Association (VESA) mounting interface standard -- an optional Cinema Display VESA Mount Adapter kit is available.

The new 30-inch Cinema HD requires a $599 (around £330) Nvidia GeForce 6800 Ultra DDL graphics card and a Power Mac G5 in order to work. The card features two DVI connectors to enable two 30-inch Cinema HD displays to work side by side. The new card will be available as a build-to-order option in new Power Mac G5s beginning in August; an upgrade kit for existing G5s will also be available at that time.

The 23-inch Apple Cinema HD display retains its 1,920-x-1,200 pixel resolution and the 20-inch Apple Cinema Display works at 1,680-x-1,050 pixel resolution. Both the 20-inch and 23-inch displays will be available in the US in July for $1,299 and $1,999 respectively (£715 and £1,100). The 30-inch display will be available in the US in August for $3,299 (£1,815). UK pricing is not yet available.
