When we tested the Iiyama E2473HDS, we had more than a few concerns about its reverse ghosting.  Now that the manufacturer has sent us its little brother, the E2273HDS, we're hoping that Iiyama will have listened to our advice and ironed out some of the problems we mentioned last time we looked at one of its monitors.  Will that be enough to guarantee it a five-star rating?

Hardware: room for improvement

The feature list doesn't set the E2273HDS apart from the crowd, and all it can go on to earn a couple of stars in this section is its meagre selection of inputs and outputs.  For video, the usual trio of VGA, DVI and HDMI are there, while for audio, there are 2 x 1 W speakers.  That's not enough to get any further than two stars ...

It seems that the switch down from 24'' to 22'' has meant losing the second HDMI port which was one of the E24736HDS' biggest strengths, but Iiyama obviously didn't want to smile on the smaller version.

Responsiveness: back to basics

This is what prevented the E2473HDS from gaining that elusive fifth star: as soon as we turned on the overdrive, we were overcome by the dreadful reverse ghosting.  Iiyama has got round the problem by giving users the choice of five different levels for overdrive, rather than a simple choice between activating it or not.

The shorter the time, the more responsive the monitor.

Configured this way, the monitor put in an excellent performance in our ghosting time tests.  It takes less than 7 ms on average for a frame to completely disappear, making this one of the fastest monitors out there.  It's perfect for gaming, as fast moving objects are always nice and sharp.

Colours need calibrating

Once we'd tweaked the settings to our liking, the E2473HDS produced some very nice colours, but the same can't be said of the E2273HDS.  Straight out of the box, it has a very strong blue tinge which leads to a colour temperature of 9000 K.  The gamma curve, which describes how brightness is distributed amongst different shades, is also out of place.  The upshot of all of this is a deltaE of 5.1.


Colour reproduction before (translucent bars) and after calibration (coloured bars)

Colour reproduction is improved by switching the colours to 'Warm' mode using the menu, which brings the deltaE down to 3.9.  The blue tinge disappears, but the gamma problems remain.  Unfortunately, all of our efforts to fix them were in vain, so the only solution if you absolutely need perfectly accurate colour reproduction is to calibrate it yourself or to try one of our calibration profiles.

The E2273HDS doesn't have any problems with contrast: it might not reach the contrast ratio of 1000:1 that Iiyama boasts about, but it comes close at 950:1, and is above the average figure we've measured on monitors up to now of 850:1.
4/5 Iiyama Prolite E2273HDS DigitalVersus 2011-06-10 00:00:00

Pros

  • Good contrast ratio: 950:1
  • Low ghosting time: < 7 ms
  • Low input lag

Cons

  • TN panel, so poor vertical viewing angles
  • Room for improvement with usability
  • Colour reproduction could do with some work

Conclusion

The Iiyama E2273HDS might not suffer from the same problems as its larger 24'' cousin, but instead adds new ones that are just as frustrating, including poor colour reproduction. Just like the 24'' E2473HDS, the smaller E2273HDS only just scrapes home with four stars.
