The Iiyama Prolite B2403WS marks a point in the history of LCD screens.  As some of those who are on hand to witness and document this historical event, we bring your attention to:

- its pre-calibrated colors, which results in better than average fidelity;
- its ergonomics : HDMI input, vertically adjustable base, and it rotates
- the price : it’s a 24 inch launched (in September) for a recommended price of 499 Euros.
- its reactivity: after adjustment it is indeed very good and superior to that of 6 ms PVAs (for example, the Dell 2407WFP) and 6 and 8 ms MVAs (ViewSonic VX2435wm).

It’s unique because you can adjust reactivity!

It’s so poorly conceived that we almost missed it.  Moreover, in our first review on Behardware.com, we didn’t find it and had to go back and make a correction to the article.  The iiyama representative wasn’t even aware of this ‘'option''. In short, the first maneuver consists of going into the OSD in the miscellaneous menu and finding the OD option for  OverDrive.  (This is a technology which helps to accentuate the voltage in liquid crystals to make them turn quicker for more detail.) Instead of 0 or 5, which theoretically corresponds to the maximum and minimum, opt for an OD of 2.  The result is miraculous with a very noticeable decrease in afterglow.  And what’s even more impressive is that with games, the B2403WS goes from being the most subject to afterglow of all 24 inch screens to "the most reactive ever released"!  It can now be compared to 2 ms TNs, such as the Samsung 226 BW S series which we actually compared side by side.

Very reactive and pre-calibrated: It’s great!

This comparison is also valid for the colors displayed by these two screens.  Indeed, the Prolite B2403WS is not only very reactive, but it’s also pre-calibrated.  There is no adjustment needed because color fidelity is good from the start.  For those interested, the average difference on the 18 standard colors is only 2.4.  Or according to Behardware.com grading, this screen is in the A class in this domain while most other screens are class C.

Update and completion of tests (9/15/2007) :

Display frequency: The OD function is deactivated – increasing afterglow – when the screen is set to a frequency superior to 60 Hz.  Either way, you don’t want to set this parameter any higher because even if you choose 75 Hz in the hope of increasing the image display rate, the screen will in the end only stay at a real speed of 60 images per second. It will try to display 75, however, one in five will skip, also resulting in a lack of fluidity in games.

Displaying a game in a smaller resolution:  In the end, there is a 1:1 mode available by changing this in the options menu in order to display a resolution smaller than the native one, however, there are black bands on the sides.  Someone on the forum (''hop'') launched Fear in 1024 x 768 on his screen instead of 1920 x 1200 (to gain in display rate on a relatively weak graphic card). This resulted in lateral black bands, but not on the upper and lower edges.  The image wasn’t deformed but was a little stretched and therefore a bit degraded.  Another problem, and potentially more bothersome, was that in 1:1 mode the overdrive (OD) is deactivated.
 
Finally, the last small problem is that like all TN panel equipped screens, viewing angles are smaller than with other technology types.  In particular, from below the image starts to darken quickly.
