It is difficult to justify buying an electronic device that costs $ 2500 or more. The HP DreamColor LP2480zx costs $ 2500 if you buy it directly from HP, but you can find it for $ 2,900 to $ 3,000 from other online stores. At these prices, only graphics professionals should consider this monitor, and it will not disappoint them.

The DreamColor LP2480zx color rendition and black level are easily combined in the same league as the NEC MultiSync PA271W, and even surpasses the NEC in color saturation and screen uniformity. Unfortunately, where the LP2480zx fails, it lacks calibration options compared to the PA271W. With its extensive array of sophisticated calibration options and lower cost, the NEC MultiSync PA271W is a clear value winner. However, if price is not the object and performance is paramount, the performance of the LP2480zx is second to none of the monitors we have considered.

Design and features
The 24-inch HP DreamColor LP2480zx has a thick 2.25-inch deep dark gray panel that expands an additional 1.4 inches to accommodate its connectivity and ventilation system, providing a full monitor depth of 3.65 inches. To prevent the monitor from looking significantly, the panel has several vents on the sides, at the top and bottom, in addition to the ventilation system at the rear. Overall, the panel is 22.2 inches.

The rectangular monitor stand is 12 inches wide by 8.1 inches deep. Built into the top of the stand is a round section that extends the depth of the monitor to 10 inches from the original 8.1 inches.

Ergonomic monitor settings include a 35 degree tilt, left and right 45 degree rotation, 90 degree rotation, and 4 inch screen height adjustment. At a minimum, the screen is 1.7 inches away from the desktop; this is 5.7 inches from the highest level of the desktop. There is a built-in neck hole on the stand that acts as a cable router.

To hit the monitor on the sides, as we know it when we behave incorrectly, is like hitting a brick wall. The 25.72-pound monitor is unlikely to budge, even when struck with a particularly heavy blow.

Monitor connection options include two DVI ports, an HDMI port, a DisplayPort, a component connection, an S-Video port, a composite video connection, and a USB stream port. All connections to the display are located under the back of the monitor; on the right are four vertical USB ports.

The monitor screen button is located in the lower right corner of the panel. It has five buttons that are vertically aligned. Navigating the screen takes some getting used to; his “Enter” button didn’t always answer, and frustratingly, she had to press it up to three times before she registered the action.

The on-screen display allows you to adjust the brightness, color temperature and black screen level; however, it has no contrast or individual color settings. Unfortunately for HP, given the graphic design market that the LP2480zx is clearly focused on, the large selection of NEC MultiSync PA271W OSDs was much more impressive.

The default settings for the LP2480zx OSD include Full, AdobeRGB, Rec.6.01 (video encoding standard), sRGB, Rec.709 (high definition standard), SCI-P3 Emulation and User-7. Each preset adjusts the colors and brightness to suit the task. The on-screen display also includes several setting options and the Picture-in-Picture (PIP) setting.

We tested the HP DreamColor LP2480zx through its DVI input connected to a Windows Vista PC using a DVI cable. The display shows a composite score of 98 for performance tests based on CNET lab display scores – the same score as the Dell UltraSharp U2711 and NEC Multisync PA271W. Throughout our DisplayMate tests, the LP2480zx provided near-perfect color reproduction. In our Black Level test, the LP2480zx crush only very dark grays and be able to display up to two grays – two levels above true black. This indicates the optimum level of black for the display. We were particularly impressed with the display’s ability to present nearly 100% even backlighting and the smallest amount of backlight that comes from what we haven’t seen before.

We did not see any color problems with the black text on the white background, and the fonts were clearly visible up to 6.8.

We tested the HP DreamColor LP2480zx using the Blu-ray version of Avatar. In the movie, we saw the exact color with very little green pressing when previewed in Rec.709. I want to point out again how light the green push is. This is hardly noticeable in ordinary circumstances and was only seen sitting next to the Dell Ultrasharp 2408WFP playing the same scene. When we went to full preset, the green push was no longer noticeable. The LP2480zx made it easy to see dark details such as braids in Na’vi’s hair during the night scene.

Through our deep familiarity with World of Warcraft, it remains the best tool we can use to judge color quality and game brightness. The LP2480zx delivered high-resolution images as standard in advance. This gave the colors a brightness that we saw only like large IPS monitors such as the Dell UltraSharp U2711 and the NEC PA271W.

The LP2480zx took high-resolution photos with brilliant, deep and accurate colors.

Viewing angle
The optimum viewing angle for the monitor is usually directly in front, about a quarter of the screen down from the top. At this angle, you are viewing the colors as intended by the manufacturer. Most monitors are not considered in any other angle. The image quality at sub-optimal angle depends on the type of panel. Most monitors use TN panels that are too bright or too dark on parts of the screen when not viewed from optimal angles. On the other hand, IPS panels typically show only minimal color shifts with an angle change. The HP DreamColor LP2480zx has an IPS panel, and when viewed from the side, we noticed that the screen darkens about 15 inches from the center, meaning that it has twice the viewing angle than the typical TN panel.

Recommended settings and usage
For general use, photo viewing and gaming, we have found the full LP2480zx preset as the optimum picture setting. To watch movies, it was best to preset Rec.709 until the color temperature was adjusted to about 7500K-8000K.

As with most IPS-based monitors, HP ships the DreamColor LP2480zx primarily for professional use where accurate color reproduction is required; however, the monitor is also great for watching movies, playing games, viewing photos and sharing.
