For those who don't know, LED monitors are just LCD monitors that use bright white LEDs instead of fluorescent bulbs as the backlight.The main advantage of LED monitors is that they consume much less power than traditional monitors. They can also have improved contrast ratios since LEDs can be dimmed over a wider range of brightness (the backlight is dimmed when displaying dark colors). For accurate color reproduction when photo editing, either LED or LCD technology would be fine. The best monitor for the job would depend on other factors such as panel type. A more expensive IPS panel would be better than a cheaper TN panel that would have significant color shifting when the viewing angle changed.
