Lenovo offers impressive new environmentally-friendly (and LED backlit) displays

With rising energy costs, people are looking everywhere they can to cut costs.  Compact fluorescents are replacing traditional incandescents.  People are foregoing air conditioning.  Not even computers are escaping the trend, and you only need to look toward the spate of low power computers and components from essentially everyone to see that.  One area that seems to have been overlooked, however, is the display, and Lenovo is rectifying that with the release of several new monitors with an environmental bent.


On the low end of the scale is the L1700p.  New electronics and display technologies allow the 17″ monitor to use 30% less power and 50% less mercury over more traditional models.  Mercury is a necessary element for the construction of the lighting in LCDs, and a big reason why they’re less than Earth friendly.

Next in line is the L1940p.  The 1440×900 monitor features a similar 30% less juice and 50% less mercury.  The rated power usage is 16W at minimum and 23W at maximum.  That’s fairly impressive for ninteen inches.  The L1940p offers VGA and DVI-D ports but no USB.  All of the new displays with DVI-D inputs are also HDCP compliant.

The L2240p continues the lineup with a 22″ widescreen 1680×1050 resolution display.  Lenovo says it will use between 21 and 31 Watts of electricity, which it also says is 33% less than its previous models.  Mercury content is again reduced by 50% over standard.  The L2240p offers the same array of inputs as the L1940p, so nothing new there.  Both monitors do offer, however, the option of Lenovo’s ThinkVision USB-powered soundbar speaker attachment.

Finally, Lenovo is bringing out two new 24″ monitors, the L2440p and L2440x.  Both offer 1920×1200 widescreen displays, VGA and DVI-D inputs and USB hubs (1 up, 4 down).  That’s where the similarities end.  What really sets them apart, and makes the L2440x such an attractive option, is the extra effort put into its engineering and construction.  The L2440x uses white LED backlighting (Lenovo’s first) instead of the L2440p’s cold cathode fluorescent.  LED backlight tends to offer better contrast and better color reproduction over its alternative.  It also uses a lot less power.  In that vein, it’s suggested that the L2440x will use between  29 and 45 Watts (depending, naturally, on brightness) than standard 24″ displays.  Considering that the L220x, a 22″ 1920×1200 monitor that we reviewed used between 43 and 80 Watts, it’s an achievement worth celebrating.  The L2440x also offers a DisplayPort input, which is an interesting addition and worthy of note as it appears to slowly becoming more and more popular, especially on higher end monitors.

The L2440x drives the environmental aspect of its nature much deeper: it is entirely mercury, arsenic and PVC free.  It’s got a low halogen (although the exact amount wasn’t stated) content and uses 65% recycled packaging materials, which is a nice touch.  The L2240p and L2440p also use 65% recycled packaging materials (which are, in turn, 100% recyclable).  Moreover, all of the new monitors garnered both EnergyStar4.0 certifications and EPEAT-Gold level status.  Lenovo is definitely playing for keeps, here.  The L1740p is available on September 19th for $239.99.  The L2440x will command a rather hefty $749.99.

In all, it looks like Lenovo has really turned out an impressive showing.  It’s nice to see manufacturers really take a serious look at offering products appropriate for the seemingly more environmentally conscious times in which we live.  The L2440x specifically looks like it could be a very nice monitor to have.  Look back soon for our reviews on the new models.
