This plan covers:
The lifespan of a monitor is typically determined by its type, quality of components, usage patterns, and environmental factors. On average, an LCD monitor—currently the most common type—can last anywhere from 30,000 to 60,000 hours of use. This translates to roughly 10 to 20 years if used for about 8 hours a day. LED monitors, which are essentially LCD screens with LED backlighting, often have a longer lifespan due to the durability of LEDs.
However, certain factors can affect a monitor's longevity, such as the brightness level it's typically used at (with higher brightness levels potentially reducing lifespan) and the environment it's in (with extreme temperatures or humidity levels potentially causing harm). Additionally, while the display itself might last for many years, other components such as capacitors or the backlight might fail earlier and require repair or replacement.
Monitors can also become functionally obsolete before they physically stop working due to advancements in technology, such as higher resolutions, faster refresh rates, and better color accuracy, which might prompt users to upgrade even if their old monitor is still operational.
Overall, a well-made monitor used under optimal conditions with moderate use can often exceed its expected lifespan, providing many years of service.
