REVIEW: NEC LCD2470WNX Part 11
Practical games tests
To get a real feel for the suitability of the NEC LCD2470WNX for gaming, we started a long games session. The picture looks wonderful and the gamer is spoiled by the colours and the high contrast.
Unfortunately, the picture is visibly spoiled as soon as there is any movement in the game! Apparently, the Overdrive control has been badly aligned with the panel. Although there is no streaking worth mentioning and bright corona effects around dark objects are minimal, bright objects display a dark, clearly recognisable shadow behind them. Also, for fast movements of mixed colour surfaces, some psychedelic colour patterns appear in certain scenes.
LCD monitors regularly fall at this hurdle: the apparatus in front of the dirty wall demonstrates light streaks and Overdrive coronas. No problem for the NEC LCD2470WNX, but the bright light on the ceiling demonstrates dark shadows and unwanted colour patterns can be seen at the bright edge of the dark wall.
The LCD offers a games profile amongst others in the menu; this profile lowers the gamma value significantly according to our measurements. This allows dark games scenes to be brightened, but the image is "milkier".
The Games profile (right) brightens dark scenes by lowering the gamma value.
Image frequency and tearing
NEC has advertised a vertical frequency of up to 85 Hz for the LCD2470WNX. Users who wish to use the higher frequency will, however, be disappointed, since the monitor works with a fixed 60 Hz internally, like so many others.
Although the MultiSync LCD2470WNX is still suitable for occasional gamers who will not be disturbed by the bearable two-frame lag, the bad Overdrive adjustment spoils the otherwise good picture. Hardcore games would be better advised to seek out a different monitor, depending on how sensitive they rate themselves. As a result, we rate the monitor just satisfactory for frequent gamers.
Because of its set vertical frequency of 60 Hz, the NEC LCD2470WNX – as most other desktop LCDs – demonstrates a slight juddering effect when playing back PAL films, which have a frequency of 50 Hz as standard.
However, fast cuts and the rarity of horizontal camera swings mean that the juddering effect is noticed by few users. There are also standalone players and software players that are capable of converting PAL films to 60 Hz and thereby play them back almost judder free.
"Brasil", together with a look at the monitor technology of the future: old material reworked for DVD; the NEC reveals the rather bad quality of the film.
