Design: a big stand—but very handyIiyama 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 changesGetting 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.
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.
- Great stand: height-adjustable, rotates and portrait mode
- Low ghosting time: < 10 ms
- Accurate colours after calibration: deltaE: 2.9
- Contrast: 1000:1
- TN panel, so poor vertical viewing angles
The Iiyama ProLite B2475HDS monitor has earned its five-star rating with excellent colour reproduction and contrast, good response times and a handy stand.
