Dell S2440L full review
No physical buttons are present on the Dell S2440L display. Instead an illuminated column of small white LEDs appears from behind the glass at the approach of your hand. Touching one of them brings up an on-screen control menu which is navigated simply by touching the dot nearest to your desired menu option. See also: Group test: what's the best display?
This system is very easy to use, but if you hate changing settings you can use Dell's Display Manager software which can automatically change monitor settings based on which applications you're running.
To the rear of the Dell S2440L, only two inputs are provided: a standard VGA port and an HDMI connector. There are no built-in speakers, but there's an audio output so you can hook up a pair of your own and route HDMI audio to them. Note that the power supply is external.
The Dell S2440L has a 24inch VA panel. Like the IPS versions that make up the rest of Dell's 'S' range, the VA panel offers vastly superior viewing angles to common TN-based displays and this means colours and brightness don't appear to change towards the edges of the screen or as your head moves about.
Dell S2440L: image quality
Although the Dell S2440L's high-gloss screen isn't to our taste, we were impressed with image quality and weren't surprised when our lab tests backed up our subjective assessment. Video looks equally impressive with very good contrast and black levels.
At full brightness we measured a contrast ratio of 1,200:1, which is excellent at this price. Dropping the Dell S2440L's brightness down to 25% boosted this to 5,060:1 which matches Dell's claimed performance and is really very impressive indeed. This means you'll experience very deep black levels, making images look great and text easier to read.
Colour reproduction was also very good, and grey-level tracking was pretty much spot on out of the box even before we applied calibration. In terms of uniformity, the S2440L was a little brighter at the top of the screen than at the bottom. The white point as also a little 'cool' at 7200K meaning calibration would be required if you wanted it to accurately display a standard white point of 6500K.
