I am wondering what is the usable (for photography) lifespan of LCD monitors. My 11 months old Dell 19" Ultrasharp monitor is being replaced (thankfully) under warranty. The monitor looks ok until I ran the calibration using an EyeOne and found that it could not reach the recommended brightness despite setting the monitor brightness to 100% (when I first had the monitor it took 15% to get the recommended value and at the last calibration took 30%). The RGB adjustments, particularly the red color, were way off from my last calibration. I suspect the backlight for red is at end of usable life. Pretty expensive to replace every year if it were not under warranty!
