The uniformity of the colors was quite good. The corners of the display appeared slightly less bright than the rest of the panel, but that wasn't visible to the eye, even if our measurement sensor caught it.
The ViewSonic monitor's colorimetry showed uncommonly good quality. The contrast and color fidelity were excellent, even with the default adjustments. You won't need 10 years of colorimetry expertise to get the most out of this unit.
The ViewSonic VX2025wm, thanks to its ClearMotiv 8ms technology, showed performance that was very comparable to a basic accelerated 8 ms MVA panel.
Note the lack of precision between 75 and 125. The monitor was slower than the NEC unit.
The VX2025 also rated a C for the lack of precision of its Overdrive.
This monitor is usable for office applications as long as you lower the brightness - though this runs the risk of losing a little chromatic quality. You can even use it for photography work due to its very natural default color rendering. The black level was good, and the images didn't show the exaggerated contrast that you often see with LCD monitors.
As for video games, we have the same comments as for the NEC monitor; it would be hard to say which of the two is faster. Games were fluid, the colors were pleasant and darker areas showed good detail, but sticklers will undoubtedly notice the chromatic aberrations in transitions between dark colors.
The same applies to video: the images were noisy, but less so than on the NEC, admittedly. Video was quite viewable from a slight distance, but the performance was a far cry from what the best 19" monitors can do.
The VX2025wm's performance is exceptional for a 20" monitor. It's a very good product from a maker that is a stalwart in the LCD market.
