Even at first glance, the high-definition antireflection TN display of the E431 (resolution 1366×768) is nothing special. With only 112 pixels per inch, it does not support the latest Ultrabooks, which often promote 170 PPI. The brightness and contrast also appear subjectively, without particularity, as the saturation of colors. The specifications of Lenovo provide a brightness of 200 nits for the panel, but our measurements only gave 161.6 nits, well below the indicated brightness. As a result, the panel looks very dark and the brightness distribution is also inconsistent, with the lower left corner of the panel 21% lower than the center of the panel (corresponding to a general 79% distribution).

Finally, the contrast ratio is perhaps the most disappointing of all; Although the Lenovo data sheet mentions a ratio of 500: 1, we only measure 234: 1, less than half the indicated value. Our subjective measures reaffirm our subjective impressions of panel color reproduction. With a color coverage of only 56% of the sRGB resolution, the E431 screen is far from adequate for applications with precise colors, such as photo editing or graphic design. However, it suits many of its competitors and should be sufficient for the daily tasks of the office. The results of CalMAN 5’s previous calibration indicate significant differences in the red, blue, cyan and magenta channels, all of which gave DeltaE values well above 10. After calibration, only red and blue are it remained substantially inaccurate. Thanks to the low brightness and low contrast ratio, the only way to save the outdoor use of the E431 is its anti-reflective finish. Using the device in the shade is not a problem, but as soon as sunlight is introduced, things become much harder to see. As with almost all low quality TN displays, the viewing angles on the E431 are very restrictive. Horizontal deviations do not produce serious detrimental effects until the angles are sufficiently obtuse, but any vertical movement quickly produces discolored colors and inverted brightness, especially when the panel is viewed from below. The E431 can be configured with processors ranging from the Intel Core i3-3110M processor to the quad-core i7-3632QM processor. Our test unit included an Intel Core i5-3230M processor, a two-core Ivy Bridge model with a base clock frequency of 2.6 GHz. Via Turbo Boost, the processor can automatically accelerate (if necessary) up to 3.0 GHz ( for 2 active cores) or 3.2 GHz (for a single core). In memory, our E431 included 4 GB of DDR3-1600 RAM (PC3-12800) using a 4 GB Hynix DIMM. This leaves an open slot for easy updating of up to 8 GB (again, through the hatch on the bottom of the laptop) or up to 16 GB in total, if desired. As always, the graphics processor is the Intel HD Graphics 4000, whose performance has been comprehensively covered in previous articles. Its clock frequency varies according to the CPU with which it is coupled, but in the case of our particular evaluation unit, it is between 650 and 1150 MHz.
