The VA1938w-LED from ViewSonic is an LED monitor whose image processor adjusts the screen according to the brightness of the room, which not only saves energy, but lessens the strain on your eyes. Its Eco mode is capable of cutting the monitor's power consumption in half, and can increase its longevity by 70 percent. At 19 inches, it's not huge, but it's pretty reasonable at $99.99 on Tiger Direct.
