BenQ GW2406Z

PC Advisor - - CONTENTS -

In re­cent years, AOC has been the go-to brand if you wanted a cheap IPS PC mon­i­tor. But other man­u­fac­tur­ers have been quick to re­lease their own mod­els, and BenQ’s new GW2406Z should prove tempt­ing at just £120.


The GW2406Z isn’t aimed at gamers specif­i­cally – IPS screens don’t have the fast re­sponse rates of TN pan­els. But for ca­sual gamers it will be fine. In­stead, this is a ‘gen­eral use’ screen that’s go­ing af­ter those that want a good-look­ing mon­i­tor and the kind of ul­tra-thin bezels we’re start­ing to see on lap­tops. Note that the dis­play it­self doesn’t go right to the edge of the panel, but stops a few mil­lime­tres be­fore it, so the to­tal bezel width is around 10mm, but has the ap­pear­ance of 5mm.

This thin­ning down ap­pears to have just one draw­back: the power sup­ply is ex­ter­nal. But it’s a mi­nor in­con­ve­nience if you can hide it out of sight some­where un­der your desk. At this price you wouldn’t ex­pect a fully ad­justable stand, and you don’t get one. The screen tilts up and down, but that’s it.

It does have three in­puts: Dis­playPort 1.2, HDMI 1.4 and VGA D-Sub. There’s a head­phone out­put that routes au­dio from the HDMI or Dis­playPort in­puts, but there are no built-in speak­ers. VGA and HDMI ca­bles are bun­dled in the box.

The 24in panel has the ex­pected 1920x1080 full-HD res­o­lu­tion, but BenQ lists it as an AH-IPS panel. This stands for Ad­vanced High­per­for­mance IPS, but es­sen­tially it is the same as other IPS screens.

You won’t find many im­age con­trols in the on-screen menu, such as gamma or colour tem­per­a­ture pre­sets, but the es­sen­tials are there. Us­ing the OSD is a pain be­cause, as with so many mon­i­tors, the but­ton la­bels are al­most in­vis­i­ble. And the five but­tons in the bot­tom edge all feel the same to your fin­gers, so it’s all too easy to press the power but­ton in­stead of the menu but­ton.


Con­sid­er­ing the price, im­age qual­ity is de­cent. At­tach­ing our Spy­der5Elite col­orime­ter, we mea­sured a max­i­mum bright­ness of 240.6cm/m2 and con­trast of 750:1 (lower than the claimed 250cd/m2 and 1000:1), but at least con­trast re­mained the same no mat­ter the bright­ness level.

At the rec­om­mended bright­ness of 120cm/m2, the black level of 0.25cd/m2 isn’t amaz­ingly inky but – again, for the price – it’s per­fectly work­able.

The av­er­age Delta E of 1.92 is to­wards the higher end of what we like to see, but in gen­eral colours and greyscale are ac­cu­rate.

Us­ing the Spy­der to cal­i­brate the screen we saw a fi­nal gamma of 2.26, which is fairly close to the ideal of 2.2. But the out of the box set­tings are not far off that, so you won’t nec­es­sar­ily need a cal­i­bra­tor.

The 2406Z cov­ers 98 per­cent of the sRGB gamut, 77 per­cent of Adobe RGB and 74 per­cent of NTSC. This, along with the rea­son­ably ac­cu­rate out-of-box colours, means it’s a good bud­get choice for edit­ing pho­tos and colour-cor­rect­ing video, al­though not if this needs to be done to pro­fes­sional stan­dards.

Con­trast is good enough, and thanks to the IPS panel, view­ing an­gles are very good both hor­i­zon­tally and ver­ti­cally.

What this means is that, un­like cheap TN mon­i­tors, you won’t be tilt­ing the screen back and for­ward to try to fig­ure out which emails are read and un­read – the sub­tly dif­fer­ent shades are eas­ily dis­cernible on the BenQ. It also means min­i­mal colour shift and bright­ness drop-off if you’re not view­ing the dis­play square on. But if you like to play a lot of fast-paced games, you might be bet­ter off with the sim­i­larly-priced AOC G2460VQ6, which has a 75Hz TN panel.


If you’re af­ter a mon­i­tor with good colours and con­trast, but aren’t both­ered about fast re­sponse times for gam­ing, the GW2406Z is a great bud­get choice. Jim Martin
