REVIEW: BenQ EW2430 Part 8

With the strongest acceleration option activated (AMA high), response times shorten significantly: The fastest grey-to-grey shift is at 11.1 milliseconds now, much closer to the manufacturer's specification. Fall times decrease slightly and are fairly even. While rise times show very strong decrease, however, only in the light measuring points, there is not much change in the darker ones. Therefore, the average for all 15 measuring points – 31.1 milliseconds – is still slower than one would have expected.

AMA high: shorter switching times, modest acceleration.

The measured brightness behaviour shows a very modest acceleration. Only at very light measurement points, there is small overshoot to the top, while at very dark spots similar overshoot directs downward. In most cases, brightness shift is, however, concluded first after two frames.

During the measurements, a third AMA option, called Premium, turns out to be a middle way between the options Off and High.

Latency

Latency is determined as sum of the signal delay time and half the average frame rate time. With the EW2430, we measure a very short signal delay of only 1.7 milliseconds, which for gamers is the more important value. Even in AMA-High setting, it takes an average of 15.6 milliseconds until the desired brightness level is reached. This is the reason why the mean total latency with a total of 17.3 milliseconds is quite long.

Subjective assessment

Without AMA option enabled, moving image content on the EQW2430 is not much fun. Even screen windows that are moved quickly pull tails behind them. When moving black windows with white lettering, there is no shimmer in shades of green, as we have seen it in other A-MVA panels, though.

With the default AMA option, Premium, these effects improve significantly, with AMA set to High, they disappear in many cases. Neither in games nor in videos, negative effects of the overdrive are observed, so user should make sure that at least the Premium setting is activated permanently.

Sound

The EW2430 accepts audio signals on both HDMI inputs or, alternatively, via the jack socket. The monitor is either able to distribute sound through a couple of speakers housed in the panel frame, or through two jack connectors for line out and headphones.

The small speakers are built-in into the panel frame.

Due to their tiny dimensions, there is not much to be expected from the speakers. After all, sound quality is sufficient for system sounds or other non-critical applications.

DVD and Video

Due to the two HDMI inputs and the additional DVI input, two HD sources, such as Blu-ray players, HDTV receivers or games console and a computer, can be permanently connected to the EW2430. Apart from that, the monitor does not provide special multimedia features like a TV tuner, picture-in-picture, or 3D.

Test of the video properties.
