Viewing serial number,
resolution mode, working time information
You may need to provide the display serial number or other information, such as the monitor resolution mode or backlight working time, to HP Support technicians to help them serve you better during a Support call.
The backlight hours refers to the elapsed time of usage for the light behind the display screen. The expected lifespan of the backlight is approximately 25,000 to 30,000 hours. At some point after the maximum usage time of the backlight has been exceeded, you may notice a decrease in brightness of up to 50%. At this point, the backlight needs to be replaced to restore full brightness.
CAUTION: The backlight can be replaced only by a trained technician. Please contact the HP Support Center for assistance. Do not attempt to replace the light yourself.
NOTE: Do not use a screen saver with the LCD monitor, as the backlight is used. It is recommended that you enable an automatic power saving mode, or switch off the monitor when not in use.
