Pivot mode
Pivot mode is less and less often to be found as it is not a popular feature. Well it should be! Even if the function is most useful for those who mostly work with two screens. Here in the office, we all work with two screens! Either with two monitors linked to a main computer (very easy to set up: graphics cards have two outs. You just need to link the screens up and start-up: both come on and allow you to work with two desktops, one beside the other).

This allows you to write on the monitor on the left, while on the other screen, you, for example, display test results. This allows you to juggle constantly between the screens.

Turning one of the screens to vertical mode, using the pivot, is more practical for text and internet. Cinema format monitors are great but if you’re word processing or surfing our site, you’ll find them less useful.
With the L2440p, Lenovo is offering us a screen that costs almost double the price of an entry level 24 inch, although its spec doesn’t make it stand out from the mass. What could the manufacturer have been thinking? The unusually good default colour settings are however perhaps the key to explaining this.
In terms of the design, those who’ve already seen the L220x will not be surprised, as it is pretty much identical. For those who are discovering it for the first time, the main surprise is the unusual base. It can move in all directions, the pivot also being height adjustable and is mounted on a platter. The obvious difference, apart from the size, between the 22 inch and the 24 inch, is that the panel is a TN, not a PVA, which means reduced visibilty from wider angles and less colour homogeneity. It still has the DVI and VGA ins and the 4-port USB hub.






Touch and go for gaming



The poor response time of the panel didn’t give much hope that we would get great responsiveness overall and this is born out in our test results. In practice, the responsiveness will be a bit too low for FPS players but good enough for the office, web navigation and other types of game. However, the low responsiveness may well be a problem when showing a video. Particularly with DVIXs, the image will probably be slightly more noisy than it would be with a more reactive monitor.

Its strong point: the colours


Even more than the ergonomics, the colours are the real ace up the L244p’s sleeve. With a deltaE of 2.2 at default settings, it is at the top of the pile. One slight reservation however, the dominant reds are slightly visible in the lightest grey tones. For the most sensitive eye, it is possible to notice this if you look at the monitor straight on, but it will very quickly become unnoticeable. If you really think that the problem persists, download the calibration profile. The contrast, at more than 800 : 1 is more than satisfactory, even if the best monitors do better than 1000 :1.

-

Very ergonomic

-

Default colour and contrast excellent

-

Low energy consumption for a 24 inch

-

Insufficient responsiveness for an FPS

-

TN panel = reduced angle of vision

With good ergonomics and accurate colours, it will meet the needs of most. Its achiles heel: fast moving games.
