iyama is back this week with another new monitor, the ProLite B2475HDS, a
Full HD 24'' monitor with a 1920 x 1080 pixel display backlit using
LEDs. The spec promises fast response times, a handy stand and great
contrast—all for a very reasonable price. If that sounds familiar,
that's because, apart from the larger display, the spec is identical to
the Iiyama ProLite B2274HDS
we tested last week. That monitor came very close to scoring five
stars in our test, so we're looking forward to seeing how the larger
version does.
Design: a big stand—but very handy
Iiyama might not make the best-looking monitors, but they're usually amongst the most flexible and easy to use.
The inputs and outputs cover all the usual bases with DVI, VGA and HDMI
ports with a headphone jack, but the most impressive aspect is the
stand. Just like all of the monitors in Iiyama's 'B' range—including
the ProLite B2403WS and the ProLite B2209HDS
amongst others—the B2475HDS is height-adjustable, sits on a rotating
stand and can be spun round to portrait mode. We always like monitors
that the user can adjust so they're comfortable working with the
display, rather than the other way round. A pair of speakers is good
enough for catching system alerts, but they're not really up to the job
if you want to listen to music.
Colours: accurate with just a few changes
Getting the best out of this monitor is as simple as making one small
adjustment, moving from the 'User' colour space to 'sRGB'. That brings
the deltaE, the average discrepancy between the original colours and
those actually shown onscreen, down to 2.7 from the default starting
point of 3.9. That should be enough to satisfy most people.
Still, photographers, graphic designers and anybody else that needs to
get colours absolutely perfect will want to calibrate it further.
Despite the excellent initial results, there are a couple of small
problems including a slightly low colour temperature (5600 K), that just
couldn't be fixed either via manual calibration or using a calibration profile.
It was a poor contrast ratio that prevented the B2274HDS from getting
five stars in this particular section, but the larger B2475HDS easily
manages 1000:1. That's an excellent result which makes it a deserving
recipient of five stars in the Colours section.
Responsiveness: there's Overdrive—and it works!
At long last, after a long line of monitors that suffered from
particularly marked reverse ghosting, Iiyama has finally managed to get
the overdrive right. This feature is supposed to improve a display's
response time, and on the B2475HDS, you can turn it all the way up to
four—which we recommend—without spotting any reverse ghosting. Better
still, the monitor is incredibly responsive and will definitely
impressive avid gamers. With a ghosting time of around 9 ms, it has no
trouble with displaying fast-moving objects.

measured in ms, that the monitor takes to entirely remove the
previous frame. The shorter the time, the more fluid moving

As with so many monitors, the B2475HDS definitely has some input lag—
the time between a frame being sent by the computer and when it's
actually displayed onscreen. However, it remains so minimal that it
won't have the slightest effect on your gaming.
