Jeg er stadig yderst tilfreds med min nye NEC 20WGX2 Pro.
Hovedsagelig indkøbt på baggrund af de udmærkede råd i dette forum.
Men nu er jeg begyndt at eksperimentere med at bruge skærmens såkaldte Advanced DV Modes der dynamisk kan ændre forskellen mellem sort/hvid (kontrasten).
Det dynamiske består i at skærmen uafbrudt justerer kontrast udfra en "real time" analyse af hvad der vises.
Det er selvfølgeligt latterligt at slå denne feature On til almindelig "udynamisk" brug af skærmen. Dvs det er kun acceptabelt til levende billeder (gaming, DVD, etc).
For hvis man kører med Advanced DV ON under almindeligt textarbejde så skifter kontrast og lysstyrke hvis man f.eks blokker en textstreng.
For da blokken jo mestendels vises sort så prøver DV programmet at kompensere for det højere sortindhold ved at ændre kontrast/lysstyrke.
Meget sjovt (de første par gange).
Men hvis man derimod gamer eller ser DVD og billedet skifter fra lys til skygge så kompenserer DV programmet lynhurtigt, så der faktisk bliver bedre (grå)opløsning i skyggerne. Dvs selvom det er kunstigt så bliver skærmen faktisk i stand til at vise flere grå nuancer på denne måde.
Jeg har nedenfor sakset nogle forskellige vurderinger af denne Advanced feature.
Der er bl.a et interessant skema fra firingsquad der viser black/white og kontrast med henholdsvis Advanced DV Off/On.
Også den sidste er sjov. Fyren kan tilsyneladende overhovedet ikke se nogle sorte nuancer på NEC skærmen:-)
Jeg selv er efterhånden begyndt at blive "adicted" på denne feature til bilspil. Da jeg synes at der kommer betydeligt mere knald på farver og kontrast.
Der er fandme fede farver på, mand. Som vi sagde engang:-)

To further boost the contrast ratio, NEC offers an "Advanced Dynamic Video Mode" which increases to as high as 1600:1.
When displaying a dark image, the monitor can automatically dim the backlight depending.
This technique is used widely by high-end LCD televisions, but NEC is one of the first to offer the feature in a desktop LCD monitor.
Photographers requiring color-critical work may find the advanced DV mode to be a bit distracting and the standard display to lack sufficient contrast. The 20WMGX2 was clearly designed for gamers rather than photographers.
BLACK-LEVEL WHITE-LEVEL CONTRAST-RATIO

While the 20WGX2 offers an Advanced DV Mode on top of its smaller brother's DV Modes, we'd recommend using it with care;
it sometimes gives you a brighter, picture, but at other times, it overeggs the pudding with strident colours and a blinding glare.
In fact, the 20WGX2 occasionally makes you wonder if a monitor can be too bright.
The 470cd/m2 luminance rating and 700:1 contrast ratio - which can be overdriven to a staggering 1600:1
- sound great on paper, but they don't suit every app.
Throttle them back, however, and the results are quite astonishing.
The 20WGX2 delivers incredible clarity, and triumphed in the white level saturation tests, delivering the best performance of any of the monitors.

Kontrasten uppges till 700:1 och otroliga 1 600:1 med vad NEC kallar Advanced DV mode. Skärmen har fem andra dv-lägen utöver det avancerade: standard, text, film, spel och foto.
Sämre med dv-läge
I praktiken är kontrasten i mörka delar av bilden inget vidare och den blir faktiskt ännu sämre om vi väljer något annat dv-läge än standardläget.
I ljusa delar är kontrasten över lag mycket bra och blir något bättre med dv- lägena. Vårt råd är att aldrig lämna standardläget utom möjligen när du spelar spel eller ser på film.

NEC 20WGX2 complete shit for photos?
Argh, here I am with a NEC 20WGX2, and while the image is colorful and pretty, the black levels are absolutely TERRIBLE. I've been trying all the DV modes, all possible brighness/contrast combinations, and fiddling with QuickGamma to try to bring them up. Unfortunately, no matter how hard I try, I can't see any darks below RGB 10,10,10, which is utter garbage. My broken old CRT will start showing it around RGB 3,3,3! If I remember correctly, the NEC LCD2070NX actually showed up around 5, which was acceptable, but editing black and white photos on this screen is impossible, when the lower half of the spectrum shows up as a big black blob.
The special DV modes have insane banding, and advance DV will actually adjust brighness and contrast depending on what your screen is showing, so moving a photo around will make the same pixels look brighter and darker depending on where they are on the screen, which is, again, utter garbage.
I haven't tried gaming or movie watching or anything such yet, but so far the glossy coating seems more pleasant than the matte alternative of the 2070NX, but with the crappy blacks I am miserable with this screen.
I'm hoping other 20WGX2 owners will assist me and check where they start seeing the gray square on the following page:

Please report back if you can see it below 10,10,10 without bringing dithering about, and at what settings.
