The studio wanted a panel with a wide colour range and good linearity suitable for movie editing as well as stills, and the HP DreamColor LP2480zx is the result - or so we're told.
We're also told that this 24in panel displays billions of colours, which may be true, but it's neither useful nor unique. Most high-end panels include 12-bit colour control rather than the HP DreamColor LP2480zx's 10-bit control but your eyes can't distinguish billions of distinct colours anyway.
Visually the HP DreamColor LP2480zx is chunky and no-nonsense. The bezel is a dark charcoal with a minimum of extra lettering and a single, small, stick-on graphic.
The separate clip-on stand allows you to tilt, swivel, and adjust the height. The HP DreamColor LP2480zx can also be rotated into portrait mode, although it scrapes the base when you do this. The OSD buttons are recessed into the bezel and light up when you press them. Legending appears next to them on the main panel - a very nice touch. A hood is available for an extra £60.
Around the back of the HP DreamColor LP2480zx there's almost every connector imaginable, including DVI-I, Display Port 1.1, HDMI, and also S-Video /Composite video. A picture-in-picture feature means you can preview content from one connector while continuing to work on another.
You'll need a calibration session to balance the colour closer to absolute neutrality, but there's no calibrator bundled with the HP DreamColor LP2480zx, just an option to buy one as an extra from HP for £150.
The calibrated curve was very linear with a hint of a green boost to compensate, but the low-end greys were slightly wobbly. Otherwise, the HP DreamColor LP2480zx showed one of the widest gamuts we've ever seen, with the triangle plot reaching almost to the edges of red and blue and well into the green.
Video was a touch fuzzy with the usual 12ms switching time but there was plenty of spare brightness and a wide viewing angle.
