Lenovo ThinkVision L2440p 24-inch LCD Monitor

Lenovo ThinkVision L2440p


The Bottom Line

Mat 4 2009 - Lenovo's ThinkVision L2440p offers a very good monitor for those looking to use less energy with their computer. The screen is able to maintain a high level or color, contrast and brightness but at half the energy consumption of a typical monitor. It is also nice to see them include a full motion stand unlike many that are going to simple tilt adjustments. The downside is that the monitor has a color shifting propblem when viewed just slightly off a direct angle and it is not as energy efficient as some newer LED monitors.

Guide Review - Lenovo ThinkVision L2440p 24-inch LCD Monitor

May 4 2009 - The primary design behind the Lenovo ThinkVision L2440p is to produce an energy efficient and environmentally friendly 24-inch display. They were able to do this by using more efficient backlighting that significantly reduces the power consumption. They also were able to reduce the amount of hazardous material used in the production of the panel. These various steps allowed it to earn an EPEAT Gold rating.

So, how does the panel look? For a TN based panel, quite good for its color and brightness. When first hooking up the panel at was a bit bright with a slight reddish tint but this is not uncommon in many monitors. After calibration the color was very good and the brightness was toned down to prevent washout of brighter colors. The only problem is that the screen while having a wide viewing angle, the angle for accurate color representation is quite narrow. You really need to look dead on at the screen or else the colors will drop off quickly.

Power consumption is rated at a typical 35W and a maximum of 50W. During testing, the screen averaged around 40W of power consumption with a maximum recorded of around 45W. Standby mode drew so little power as to not register on my power meter. These numbers a very good for an average 24-inch display. Typical power consumption on a 24-inch display is between 50 and 75W with maximums of around 80 to 100W. There are however a few lower power monitors in this class now that use LED backlights. Lenovo should probably look into this for their next version.

The stand is one of the better parts of the L2440p. It offers a full range of adjustments which you will need with the color shifting when off center. Built into the stand is also a cable management system that allows the cables to be tucked away from site to help keep desktop clutter down.
