We're amongst the first to have a chance to test the B2712HDS, Iiyama's new 27'' monitor.  It has an attractive spec, as long as you're not allergic to TN technology.

Handling: all the basics are there

A black matte bezel frames a refined, elegant design, while on the inside is a 2 ms Full HD TN display.  The stand is mounted on a rotating base that allows you to adjust the height of the monitor.  At the back, there are VGA, HDMI and DVI inputs for video, as well as a headphone jack and an audio line in to power the 2 x 1 W speakers.  That's a rather complete hardware offering, without quite having everything that the very best monitors provide.  It's still got what it takes to earn four stars in this section though, and it won't take much more work from Iiyama to get the fifth.

Colours: five stars out of the box!

After we left it to warm up for half an hour so, the measurements we took revealed a screen that was unusually well-adjusted.  Using the default settings, we found a deltaE of 2.0.  A score of 3.0 or below is generally considered to represent a colour discrepancy that's invisible to the naked eye for the vast majority of viewers.  At just 2.0, Iiyama joins the Samsung P2370, which was, until now, the only monitor to score five stars without any calibration.

You'll still need to make a quick visit to the menu though.  By default, the luminance is 330 cd/m², which is so bright it's going to hurt if your eyes if you look at it for too long.  For the sake of your peepers, we suggest you turn right down from 90 to 50, but that won't have a negative impact on the deltaE.  There's no need to do any more calibration, unless photo editing and detailed graphics work are more than just a hobby for you.  In that case, though, we recommend display panels using VA or IPS technology, which produce a much more even image.

The contrast is a lot worse though.  At just 830:1, the B2712BHDS remains rather average.  With colours as good as this, we had hoped it would do as well as the F2380M, which reaches 2500:1.

Gaming: turn up the overdrive and have fun!

By default, the response time of this 27'' is the same as a 5 ms monitor.  To get it down to 2 ms, you need to go back into the menus and turn overdrive up from 0 to 3, which produces excellent results.  In practice, it makes this screen ideal for even the most demanding games; or to look at it another way, using it for office work will be a piece of cake.

This monitor will be as good at multiplayer gaming as it is when you're by yourself, as it has an input lag that's hardly more than one frame, which is a small enough delay to be entirely invisible when you use it.  There's no way that you can blame the B2712HDS for your own performance during the next LAN party.

Films: no image correction

We were very disappointed to find there was no image correction chip for video in this monitor, especially given that, at 27'', it's reaching a size that could well make it a decent little television.  Instead, you'll need to choose a decent quality input, choosing your source and player carefully.  Otherwise, you'll need to be at least two metres away to avoid spotting the upscaling problems.
Iiyama fixes its reverse ghosting problems
After the problems Iiyama had without he B2409HDS and its reverse ghosting, the manufacturer seems to have learnt its lesson and has instead used a system that convinced us on the B2403WS, a great 24'' monitor in its day.

The system is very simple: it allows you to adjust the responsiveness in steps from 0 to 5 without introducing any revers ghosting.

It's a solution that other manufacturers should consider, so they can avoid ruining their monitors by pushing them too far.

For more information about the problem of reverse ghosting, consult our test of the Philips 220CW..

PROS

  • Hardware
  • Accurate colours by default
  • Very responsive after adjustment
  • Low input lag

CONS

  • TN panel, so narrow viewing angles

CONCLUSION 5/5

This is an excellent monitor that will be useful for most users, except, perhaps, for the most detailed photo editing work.
