The Lenovo L2440P widescreen LCD is one of the new Eco-friendly displays coming out of the business computer maker. From the ground up these monitors have the environment in mind, which is reflected even in the packaging, made up of 65% recycled material. This LCD sports light booster technology to have 33% less mercury content while also saving you up to 50% of the energy cost with lower power consumption.  With WUXGA resolution, HDCP support for HD movie content and multiple video inputs is there anything this monitor cant do?

Build and Design

Lenovo business monitors have a down to basics design and color scheme. Some might call the design bland, but I really like the simple approach. The stand footprint is a half circle that gives the monitor a good deal of support and the backbone of the stand is large enough to support the monitor, while carefully concealing any wires. The unimposing color layout is dark grey and blends in with other computer hardware around my desk.

Unlike some monitors that use glossy trim all around the panel, the matte finish is easy on the eyes and doesn’t distract you with reflections or glare. I just wish the “business black” finish matched my ThinkPad, so I could have the perfect color-coordinated desk at work.

For the OCD crowd that hates indicator lights, the power light is dim enough to not bother me during the day, and if you are viewing the screen head on it isn’t focused towards your eyes. This is coming from someone who frequently uses electrical tape to cover lights that some manufactures go overboard with.

Build quality is excellent with solid plastic trim all around and a stand that can easily support the weight of the monitor without sagging. The footprint is large enough to keep the display planted even if someone trips and falls into your desk. While most people will probably keep the display mounted in a single spot for its entire useful life, the matte finish would hold up well against scratches and bumps if you moved it around frequently.

Mounting Options
The Lenovo L2440p widescreen monitor includes a pretty nice stand which offers height, tilt, swivel, and pivot adjustment. Tilt range is 0 degrees forward and 30 degrees back, while the swivel range is 45 degrees side to side. Pivoting range is 90 degrees to move the screen into a portrait viewing mode and the height adjustment is just under 4.5”.

On my desk I currently use the Ergotron LX dual arm desk mount which attaches to the VESA 100mm mounting point on the back of the monitor. After using this stand for well over a year, I don’t know if I could ever move back to a stock or factory stand. Something about being able to raise the monitor a foot and pivot it over to a coworker’s desk makes it completely worth it.

Image Quality
Image quality on the L2440p display is very nice considering it uses a low-cost TN panel instead of a PVA or IPS style used on more expensive models. Color quality and white levels were very good, even sitting next to my T60 Thinkpad with the IPS Flexview display. Viewing angles were a non-issue for my work environment, with clear and accurate viewing window in all angles that I used the screen on my desk.

Black levels are good and backlight bleed is minimal on the edges. I frequently watch movies in the office and scenes set in a dark area (space) show up very well without looking washed out. During the first week using the monitor I did notice a slight difference in backlight brightness between the left and right side of the screen, barely seen when viewing solid colors across the desktop. This went away as the monitor was used more on a daily basis. In our bright office setting I found the most comfortable brightness level to be between 40-50%.

Heat and Power
As more businesses start trying to cut back on power consumption they are turning to more power friendly devices. This 24” monitor is rated to draw 35 watts during normal use, with a max of 50 watts with full backlight brightness. Actual power readings from the wall during our testing was 37 watts at 40% and 52 watts at full brightness. Compare this to the standard 22” Lenovo L220x that draws 43w watts at the lowest brightness and 80w at the highest.

Heat output from the L2440p with the lower power consumption is minimal, with the top of the monitor feeling slightly warm. In our office with the room temperature set to 74 degrees the average temperature across the top panel was 80-85 degrees. Come summer months the lower power usage and lower thermal output really makes a difference when you are fighting with the buildings AC systems.

If you are in the market for a large power friendly monitor the Lenovo L2440p is one to consider. The monitor has a really nice TN panel which is better than most I have seen, with a broad viewing range where you don’t see the limitations of the low-cost panel. Power consumption was excellent for a 24” monitor, drawing 40% less power at any given brightness settings when compared to a 22” display. The starting price of $349 is in line with other 24” displays on the market making it hard to find a reason not to buy one of these.


  • Low power consumption
  • Good color and black levels
  • Reasonable viewing angles for a TN panel


  • “Business Black” doesn’t match my ThinkPad
