Before we began any testing on the monitor, we calibrated the brightness and contrast setting using the Datacolor SpyderTV Pro software. Tests were then done using DisplayMate for Windows Multimedia with Motion Edition 2.0 at the native resolution of 1680x1050 @ 60Hz. This is a standard test we perform to help identify display anomalies and while the VX2235wm does have both analog and digital output, we will only be testing the digital output of the monitor. With a contrast ratio of 4000:1, we will be expecting some really good results on the darker shades of the monitor and hopefully no ghosting thanks to its speedy response time.
- Circular Geometry, Cross hatch and Dot
There were no distortions of the circles displayed meaning all horizontal and vertical lines were properly displayed despite the wide-screen the aspect ratio of the monitor. This is to be expected from a DVI input and thankfully it came out fine.
- Screen Uniformity
Screen luminosity was even throughout the whole panel and we were unable to detect any variations or tints across the color tests.
- Stuck Pixel
While horror stories abound of LCD panels having dead pixels on fresh new units, the VX2235wm that we tested had no stuck pixels, which makes us happy reviewers.
- Pixel Tracking and Timing-Lock
We hardly encountered any problems with this test, thanks to the DVI interface that was used. Patterns were flawless, no noise was seen and no readjustments were required. That doesn't mean all monitors on DVI connection ace this test as we've had our fare share of quirky displays, usually of poor build that give us nasty results. As such, ViewSonic's outcome is a welcomed one.
- Dark Gray Scale
The test is actually to determine the sensitivity of the black levels when set to the highest brightness setting. It was good to note that the VX2235wm held up well as the background was still black (instead of gray) and we could differentiate between the dark gray scales of the test pattern up to the threshold recommended by program (an index value of 6), thanks to the high contrast ratio of the monitor.
- White Level Saturation
White level saturation for the monitor was good as we could comfortably discern pattern index up to 251 out of maximum of 255. While it may have been possible to distinguish up to an index of 254, we felt that it was not distinct enough nor was it easy to detect.
- Color Tracking
We only had a slight problem with the red hues for the monitor as it was slightly dark in our testing. Otherwise the colors for monitor were clear and did not show any weird tints.
- 64/256 Intensity Level Ramp, 256 Intensity Color Level Ramp
No anomalies were detected for the both the 64/256 Intensity Level Ramps, which means that the gradients were generally smooth and individual bands could be easily made out. We had a small concern with the darker spectrum of the color level ramp though. This was really minor as we noticed Red and Blue having a wider separation range and thus ramped up to the highest intensity levels a little sooner.
- Scaled Font
The smallest font reading at 9 pixels (6.8 points) turned out to be quite legible and clear on both serif and san serif fonts. While obviously the high screen resolution did make the fonts hard to read from far, at normal working/reading distance with the monitor, the fonts were crisp and sharp and could be read without any problems.
