Iiyama looks to have all the ingredients for success with the XB2485WSU, including an IPS screen panel, 1920 x 1200-pixel resolution, a height-adjustable stand and a USB hub. We therefore couldn't wait to get our hands on this display to check out its performance on colour fidelity, contrast and screen ghosting time. Can it pull off a five-star review?


Iiyama Prolite XB2485WSU - portrait mode

The XB2485WSU may not look all that exciting with its matte black casing and stand, but the hardware on offer here is excellent. The stand swivels, tilts and is height-adjustable. Plus, the screen can be spun round into portrait mode, which is all the more effective thanks to the wide viewing angles brought by IPS technology.

Iiyama Prolite XB2485WSU - connections

Video connections comprise VGA, DVI and DisplayPort entries. There's no HDMI input, which isn't problematic if you're using the XB2485WSU with a PC, but it does mean you won't be able to hook up a latest-gen console or a Blu-ray player directly.

There's an audio jack entry that links straight to the monitor's two 1.5-watt speakers. Plus, the headphones socket on the front of the XB2485WSU can be used with headphones or a compatible speaker kit. 

Iiyama Prolite XB2485WSU - USB ports

The XB2485WSU has a four-port USB hub with two ports on the monitor's left-hand edge and two at the back. You can therefore easily hook up a USB flash drive, card reader or other peripheral without having to fumble around at the back of your PC tower case. Finally, the screen def of 1920 x 1200 pixels displays 10% more info than a 1920 x 1080 pixel display. For office computing or photo editing, those extra 120 lines can be a real boon.


We measured an excellent contrast ratio in this monitor, pushing up over 1000:1. The colours, however, need tweaking slightly.

Iiyama Prolite XB2485WSU - delta E colour fidelity

We measured the average Delta E at 3.9 (Delta E measures colour fidelity—the lower the better, with anything under three considered accurate). In practical terms, that's clearly good enough for office computing and for buying clothes online without unboxing a nasty surprise (believe us, we've been there). However, graphic designers and photo editing buffs will no doubt need even more accuracy in colour reproduction.

Any attempts we made to try and improve colour fidelity in the OSD in turn brought about a drop in contrast. In the end, you're better off sticking with the factory settings.


The least attractive thing about this 24" monitor has got to be its responsiveness. With the default settings, we measured the average ghosting time at 17.5 ms, which is way too high to appeal to gamers.

This graph shows the ghosting time, measured in ms, which measures the time it takes this monitor takes to entirely remove the previous frame. The shorter the time, the more fluid moving images will appear.

The menu can be a bit of a pain to use, as it's impossible to see which button you're pressing once the monitor is switched on. However, we did find an Overdrive mode (OD) in the onscreen menu, which can usually be used to boost a screen's responsiveness. In the end, though, we opted to leave this function switched off as it does more damage than good, with reverse ghosting effects appearing even at the lowest OD setting. 

The 19 ms input lag, on the other hand, is too low to be any hindrance to gamers in online multiplayer set-ups.
Power Hungry
Over the last few years, monitor power consumption has been falling in models with IPS, TN and VA panels. However, this 24" display uses almost 30 watts at 200 cd/m²—that's barely 3 watts less than the ViewSonic VP2770-LED which has a 27" IPS panel rather than the smaller 24" panel used here.


  • Screen def: 1920 x 1200 pixels
  • Wide viewing angles
  • High contrast (1100:1)
  • Practical stand
  • Four USB ports


  • Poor response time, not fast enough for gamers
  • Colours won't be accurate enough for the most demanding users (Delta E = 3.9)
  • No HDMI input


While the tech specs looked amazing on paper, this 24" Iiyama ProLite XB2485WSU monitor is only really suitable for office computing and web browsing. Then again, it's in these fields that the screen's native resolution (1920 x 1200 pixels) will be a real boon.
