If that means nothing to you, then you might like to know that IPS technology provides both wider viewing angles and a more even display than is available on the majority of other 22'' screens.
Hardware: plenty of options
There are plenty of hardware options on this 22'' display. The classic trio of VGA, HDMI and DVI inputs is there, but so is a height-adjustable stand that can both turn the screen from side to side and pivot it for use in portrait mode. There are no built-in speakers, but there is a headphone jack so you can connect any audio equipment you like. Without it, getting the audio signal out of the HDMI input would have been a lot more tricky. It's almost a shame to leave the W2220P at four stars in this section, as a simple accessory like a USB hub would have been enough to secure the fifth.
Colours: calibration is compulsory
The default settings for the W2220P aren't that great. The average discrepancy between the colours requested by the graphics card and those it actually displays, its deltaE, was 4.4: the best monitors get this figure below 2.0. This problem is mostly caused by a rather visible blue tinge. Fortunately, you can use the onscreen menu to correct things easily enough: you need to choose the sRGB colour mode. The screen ends up less bright, but the deltaE is a much more respectable 2.0. As we've said before, a score below 3.0 is usually considered good enough to produce discrepancies that are invisible to non-trained viewers.
Choosing sRGB mode also affects the contrast, which, by default, is stuck at 750:1. That's rather weak compared to the results of other monitors we've tested recently. Activate sRGB mode, and the ratio climbs to 800:1. It's still not wonderful, but at least it's closer to an average performance. As a result, this monitor scores four stars in this section after it's been correctly set up, compared to the two its default settings would have earned.
Responsiveness: good enough for any game
|Average ghosting over ten frames|
Although LG describe this as a 6 ms screen, it can display fast movements with impressive fluidity. To tell the truth, it suffers as little from ghosting as some 2 ms monitors, meaning you'll be able to use it not only for office applications but also demanding games that need a responsive display. The only screens that do much better have a refresh rate of 120 Hz, and it doesn't seem likely that we'll see a 120 Hz e-IPS panel any time soon.
To round things off, the input lag is around one frame on average. That won't hold you back during multiplayer sessions.
Movies: choose your video and player carefully
The W2220P doesn't do any worse than other monitors, and, like them, it isn't cut out to rectify the weaknesses of the video you're watching. The visual artefacts of upscaling are clearly visible, and if you want to avoid them, there are two options: sit further back (a metre or two should do it) or make sure you're especially demanding about both the quality of the video watching and the player you're using.
