To users demanding superior image quality, it's always tough to pick a right LCD monitor, since most LCD monitors are not as good as advertised to satisfy discriminating eyes. While other vendors stressed on low price, high brightness and high contrast, many products were plagued by uneven brightness, poor highlight and shadow or blurry details. Thanks to the exclusive SuperClear MVA ™ technology, ViewSonic dramatically improved LCD qualities with better evenness and wider viewing angles. In the following sections, we will further illustrate how conventional LCD panel works, as well as the secret behind ViewSonic's unique SuperClear MVA ™ technology.

The Principle of Conventional LCD Panels

Power off： Liquid crystals twist 90 degrees horizontally; the backlight passes through the polarizer to form the white pixels on the screen.

Power on： The magnitude of the power decides the angles the liquid crystals twist, thus the direction of the light passing through. When the voltage reaches its maximum on liquid crystals, their twisting angle will become 90 degrees in relation to the polarizer, which block the backlight passing through and the result is the black pixels on the screen.

ViewSonic SuperClear MVA™ Better Contrast for Vivid Colors

Some conventional LCD monitors may have attractive prices or seemingly good response time figures, however their liquid crystals inside the panels may not twist fully according to the voltage change. This would cause two problems: Firstly, the inability to block the backlight efficiently. That means only “grayish black” can be displayed even with high theoretical contrast ratios. In contrast, the SuperClearMVA™ technology employed by ViewSonic thoroughly avoided the problem with true 800:1 or 1000:1 contrast ratio capable of displaying “true black” and discernible color depth.

ost low-cost LCD monitors with TN panels usually use 6-bit IC drivers to emulate 8-bit drivers, thus the image becomes unacceptable to high-end users as a result. In comparison, the ViewSonic VX2025wm and VP2330wb employ genuine 8-bit IC drivers and are capable of offering spectacular images of professional quality.

XtremeView for Wider View

The second drawback of conventional LCD monitors is the seriously limited viewing angles. This has been a pain to LCD users for years; viewing off the axis from center of the screen always causes color shift to some extent. To relieve this problem, ViewSonic leveraged the XtremeView wide-angle technology to achieve both vertical and horizontal viewing angles of 176 degrees for more accurate and consistent colors.

Key to the XtremeView Technology

On ViewSonic monitors featuring the exclusive SuperClear MVA™ technology, “protrusions” are employed to define a pre-tilt angle for liquid crystal alignments.		Liquid Crystals with Power Off		Liquid Crystals with Power On
		With the protrusions, the liquid crystals in different areas will turn to pre-defined directions when electrically charged; and the action forms sufficient isolated areas that widen viewing angles and reduce color shifts.

Proof of Color Excellence

The “seeing is believing” principle works for judging LCD monitors as well. We used the “Eye-One Photo” color calibrator to conduct calibration tests on a ViewSonic VX2025 and a brand-name LCD after one-hour uptime. On the following figures, each monitor produced two charts: the straighter RGB curves on the left mean better color output, or closer to the ideal value; while the triangle on the right covers the gamut the monitor is capable of displaying, larger triangle represents better color output variation.

t's apparent that the blue line of the non-ViewSonic monitor drifted away from the center, while the same curve was almost perfectly straight on ViewSonic VX2025. In addition, VX2025 also covered a larger gamut, especially on the red tip.
