I have a 24 LCD monitor for work, (new) that company policy dictates must be on during work hours (9 hours a day, not sure of the logic behind it). I was wondering how long this would span before it dims or goes dead.Details - Resolution of 1920X1080, 60Hz refresh rateThe input is either HDMI or DVI.125v power cord.
Most LCD monitors have a average backlight life of about 60,000 hours. That's about 7 years. It may go a bit dimmer after a few years, but it should be good for a while There is no reason at all to leave a LCD monitor on all the time, you should turn it off when not in use anyway Like above says, put a screen saver on it, to power off the monitor (power settings) after a certain time - that will save power in general and the life of the monitor.
You need to make sure the power to the monitor (and your computer) is as clean as possible, meaning through a surge protector /or an UPS. You can have power and screensaver control configured on your computer that will turn the monitor off when the computer is idle for so many minutes, like say 20. This power management can and should be configured for your computer too. In such a scenario your monitor will last for a very long time, say about 5 to 7 years or thereabouts. Good luck.
