But, if the Movie, Dynamics and Photo modes are simply more of the same, the Action Game and Racing Game modes activate what BenQ calls PerfectMotion – a technology that’s “Pre-Programmed For Maximum Excitement” apparently. Marketing slogans aside, PerfectMotion is a combination of two different processes designed to improve motion perception. In fact, the first half of this technology is fairly ordinary since it’s an overdrive mode common among most TN Film displays; however, the second ingredient is far more interesting.
It’s known as Simulated Pulse Driving (SPD) and it uses a technique known as Black Frame Insertion (BFI) to essentially trick the eye by inserting black frames between the normal ones, creating smoother and less blurred motion that BenQ argues is more akin to a CRT. It’s not a claim we’re especially convinced by, but it’s undeniable that it does have an effect. You still get an element of afterglow that to an extent is unavoidable, but it definitely reduces the level of smearing present and makes for slightly smoother and more pleasing motion.
However, though this does work well enough, you’ll soon be put off by the fact that the extra black frames make the overall picture intolerably and irreversibly dark and murky. Thus, otherwise colourful and vibrant scenes look like they’ve been doused in several layers Los Angeles smog. It’s rather like a cure to the Common Cold that makes you partially blind, removing a tolerable annoyance but introducing something far less palatable. Some might be able to convince themselves otherwise, but they’ll be in the minority.
As for panel specifications, everything is as one would expect. The X2200W can produce the full 16.7 million colours, according to BenQ at least, it’s another to feature a wider 92 per cent colour gamut. And, while we’ve remained healthily sceptical about claims regarding colour production on TN Films screens, there’s some evidence to suggest these newer examples are indeed producing 16.7 million colours, albeit due to more advanced dithering techniques. A contrast ratio of 1,000:1 and brightness of 300cd/m2 are perfectly acceptable, while BenQ is good enough to quote both the typical response time of 5ms and the Motion Picture Response Time (MPRT) of 8ms.
It also quotes the viewing angles, which are 160 degrees vertical and horizontal. Of all the aspects of the TN Film displays this is still the weakest, despite the fact that there’s been significant improvement. Overall, it means a noticeable loss of both brightness and contrast when viewing from an angle, though there’s none of the nasty colour distortion of old. For most, though, this won’t pose too great an issue.
