HP LP2480zx Driver
It consists of five buttons, aligned vertically.
Navigating the OSD took some getting used to; its "Enter" button was not HP LP2480zx responsive and, frustratingly, needed to be pushed up to three times before it would register the action. The onscreen display lets you adjust the brightness, color temperature, and black level of the screen; however, HP LP2480zx doesn't have adjustment options for contrast or individual color. This lower range is needed in the Motion Picture Market.
The Contrast Ratio is The display is aimed primarily in the HP LP2480zx and motion picture market place, where they have a number of color space standards based upon media and content delivery. The "shift on the fly" color space HP LP2480zx is very suited to color evaluation in these markets.
Furthermore, the screen uses a tri-colour LED backlight, which is supposed to produce deeper colours than a fluorescent light; this is definitely noticeable. Another advantage of the LED light is that the monitor achieves its required brightness level as soon as it's switched on, without HP LP2480zx any HP LP2480zx time.
Straight out of the box, it was impossible HP LP2480zx fault the screen's colours. All the colour ramps and gradients we threw at it using DisplayMate were handled impeccably.
There wasn't any colour stepping, hues weren't off, and its colour intensity from one level to the next was perfect. There are different colour spaces that can HP LP2480zx selected from the on-screen menu, which HP LP2480zx controlled with easily accessible buttons. The monitor automatically stores the new setting, then recognizes the new mode just as it does a preset mode.
In addition to the factory preset modes, there are twenty user modes that can HP LP2480zx entered and stored. Energy Saver Feature When the monitor is in its normal HP LP2480zx mode, the monitor uses less than 90 watts of power and the Power light is green. At the factory, the system is put into "open loop" mode and an external colorimeter is used to measure actual values; this data is stored in the chip and is used for calculations during normal use.

HP LP2480zx disassembling the monitor, the first step was to unplug the sensor from the LED driver board. I didn't have very high hopes but I powered on the monitor. For the first time, HP LP2480zx saw a pure white background in the "check video cable" message, instead of a purple-tinted one.
Unfortunately this was short-lived, since any attempts at adjusting the monitor's settings or even leaving it alone for a bit resulted in each backlight color fading to a single channel within a few minutes. HP LP2480zx a complete power-down of the monitor would bring back the brief white backlight. One possible solution would be HP LP2480zx modify the factory calibration data on the chip.
Unfortunately this would be a short-term solution since the color sensor would continue to wear out and this wouldn't work if the sensor aged HP LP2480zx far. I also lack HP LP2480zx equipment and skills to remove and reinstall a surface-mounted chip in order to send it the necessary I2C commands, and the datasheet isn't clear on how to format the data.

Another possible solution would be to use a variable resistor to compensate for the sensor's output. I did HP LP2480zx have success with this splicing the resistor into the green channel.
Due to the system operating in a closed loop, having the resistor even slightly HP LP2480zx would result in similarly invalid results.
