Obviously, the OSD also offers a large selection of colour temperatures and most intriguingly, modifiable overdrive - or at least that is what we assume the menu means by adjustable response time settings. There are Standard, Advanced and Ultra Fast modes, which should oscillate between the ViewSonic VP2250wb's 2ms (maximum overdrive) and unknown native response times. The optional (since it is nice for gaming) elimination of overdrive is, in my opinion, a necessity for any TN monitor with ambitions towards graphics use.
Another rare enough feature (though the scenarios in which it might prove useful are limited) that we find in the VP2250wb is reverse interpolation, or downscaling. Essentially, this means that feeding the 1680 x 1050 panel a 1920 x 1200 feed does not result in the usual black screen or out-of-range warning, but in a usable desktop. And the monitor helpfully throws up a notice for half a minute, politely informing you that you might want to change the source to match the panel's native resolution.
But the one area where a monitor with professional aspirations obviously needs to excel is in terms of image quality and while the VP2250wb is good, it might not be quite good enough. First impressions were very encouraging indeed, with excellent viewing angles, and the Windows desktop practically leaping off the screen thanks to rich, vibrant colours. In fact, you could easily be forgiven for thinking the panel was some form of PVA or IPS.
However, minor problems start with these very viewing angles. Although they are undoubtedly very good for a TN panel, and perfectly adequate during normal use, there is a slight colour shift that might make it unusable for your intended purposes. As I said, it is very minor, and will only change a hue of purple to a slightly different purple value. But for graphical professionals it might be enough of a difference to matter.
Contrast is generally outstanding, and again unusually for a TN the VP2250wb breezes through our gray-scale tests without any problems, easily differentiating between dark blacks while displaying pure whites. There is absolutely no evidence of banding and the whole experience is very vibrant, eschewing the usual faded colours that can affect TNs after re-balancing for accuracy.
