Iiyama's monitor range just keeps on growing.  The X2472HD and E2472HD that we tested in the past few weeks didn't blow us away, so we're hoping that this new 24'' monitor with a 2 ms TN panel, the Prolite E2473HDS, will help revive the brand's reputation.

Update: November 28, 2011
As promised, Iiyama has updated its overdrive system—but the new version of the ProLite E2473HDS has exactly the same model number as the previous one with the old system.  The manufacturer has promised that the updated versions have been shipping since September, but there's any easy way to check whether you have the new model.  On the serial number sticker which you'll find on the left-hand side of the box, is a grid with eight letters.  If A and B have been blacked out, then you're fine.  But if they're still visible, send your new monitor back: it's still got the old overdrive system which leads to reverse ghosting.

Hardware: two HDMI inputs

In the past, Iiyama made do with relatively plain black and grey monitors with a plain matte finish.  But for its recent range of 24'' monitors, it's moved over to a glossy finish with fewer sharp edges and a much slimmer profile.  The new look is much more in keeping with modern monitors, but unfortunately for Iiyama, aesthetic considerations aren't taken into account when we decide on a hardware score for monitors.

Iiyama's 'E' range monitors all have a very basic stand that only allows users to tilt the display back a few degrees.  At the back, the standard trio of VGA, DVI and HDMI are joined by some speakers.  There's a second HDMI input and a headphone jack on the side, and it's the additional HDMI port that allows the E2473HDS to go beyond two stars and reach a reasonable three star rating in this section.

Colours: starts out good and just gets better

With the default settings, the deltaE—the average discrepancy between the 'perfect' colours and those actually shown on the screen—is just 2.9.  That means we can already credit the E2473HDS with accurate colour reproduction.  Looking at the initial results, though, and especially the blue tinge, we're pretty sure it can do even better ...

We were right: choosing the 'Warm' colour temperature sends the deltaE down to 1.9.  The difference is most visible with flesh tones, which otherwise have a slightly purple look.

It's a shame that the contrast isn't quite as perfect as the colour reproduction.  With black levels of 0.26 cd/m² against a white background of 200 cd/m², it doesn't reach the average of 850:1 we've found on other monitors.  It doesn't go any higher than 770:1 in fact.  Fortunately for Iiyama, these problems with contrast aren't enough to wipe out the gains made by the excellent colours, meaning the E2473HDS still comes away with five stars in this section.

Responsiveness: 2 ms?  Try fixing the overdrive ...

Anybody who tries to transform their 5 ms monitor into a 2 ms display by turning on the 'OD' feature is in for a nasty surprise.  By trying to reduce the ghosting time, it actually creates an irritating reverse ghosting.  It's better to not bother and stick with the original, slightly slower, response time.  That might not be enough to impress hardened gamers, but the reverse ghosting is much more annoying.

Update: November 28, 2011
With the new overdrive system, you can still enjoy a responsive monitor without having to suffer reverse ghosting.  The trick is to set overdrive to 3, which sends the ghosting time tumbling to an average figure of 10.5 ms.  Fast-moving objects now look smooth enough to please most gamers, earning the E2473HDS an extra two stars in this section, taking it up to four, rather than two out of five.

Finally, there is some input lag, but it's so small as to be invisible to the naked eye.  That means the E2473HDS won't be holding you back when gaming online or at a LAN party.


The picture with SD quality content isn't much different from what we've come to expect from the vast majority of other monitors.  The E2473HDS struggles to do a reasonable job of upscaling content that isn't 1080p.  Once again, this job is better off left to video player—whether that means relying on hardware (a Blu-ray player or a games console for instance) or software (like VLC or Media Player Classic ...).
4/5 Iiyama Prolite E2473HDS DigitalVersus 2011-04-08 00:00:00


  • Accurate colours: deltaE of 1.9 after configuration\nTwo HDMI ports\nLow input lag\nHardware options slightly wider than on most other monitors
  • Responsive


  • TN panel, so poor vertical viewing angles
  • Below average contrast


With accurate colours, improved hardware and a responsive display, the Iiyama E2473HDS more than earns its four-star rating.
