Display

The display on our review model is a 6-bit LG LED backlit panel. Lenovo's official spec sheet lists this screen as 300:1 contrast, but the LG specification is 500:1. Overall the panel is easy on the eyes with even light distribution and a wide adjustment range for the LED backlighting. The highest backlight setting is very bright, easy outshining my IPS FlexView panel by a wide margin. Colors are vibrant, although the whites do lean heavily on the cooler/blue side. Vertical angles are better than average, with a modest sweet spot before colors start to invert and wash out. Horizontal viewing range is better, with colors washing out slightly, but still staying accurate.

For those curious about sunlight readability, I ventured outside on a very bright and sunny day to snap some pictures of the T400 at max brightness. The picture makes the screen out to be just a tad dimmer than it looks in person, but it is perfectly serviceable outside. The only thing that would really prevent you from seeing the screen is reflections blinding you from just being outside on a sunny day. You should also note that max brightness chops about one hour of battery life away from the 9-cell model where it would otherwise be pushing close to 10 hours at 60% brightness.

Battery

We recommend the 4-cell Li-Ion battery. It is the only battery size that doesn’t stick out of the back of the laptop while giving you the need computing power.
