Everest's Monitor Diagnostics provide a few key test patterns that allow us to evaluate various aspects, such as color accuracy and uniformity. We ran through all of the screens, and captured a few that had points of interest.

A sample of the screen diagnostics available with Lavalys' Everest Ultimate Edition
We ran the Everest's monitor diagnostics test with the VH242H set to its factory defaults as well as with a few tweaked settings to optimize the display. The VH242H performed well on nearly all of the tests. It did a great job on the grid and text reproduction tests, producing clear and sharp patterns and text. The MK241H also did well on most of the solid color, color gradient, and color palette tests. It also performed well on the white, gray, and black fill tests. We were especially impressed with how well the monitor was able to display dark blacks without any noticeable light spillover from the backlight.
The monitor was not perfect, however. At its default settings, the VH242H's contrast was set a bit too low--on the Brightness/Contrast Calibration Test, the two darkest black targets (0.4% and 1.6%) were not discernable from the completely black background. Increasing the contrast slightly, fixed this. A moiré pattern was noticeable on the dots test; and the moiré pattern got even worse on the vertical and horizontal lines tests. It is important to note, however, this is a common malady that impacts many LCDs. We were able to diminish the moiré patterns by reducing the VH242H's sharpness setting; but this was at the expense of creating a rather blurred image on the display. Additionally, the MK241H didn't make it out of all of the solid color tests screens completely unscathed: The orange, white, and gray solid-fill screens suffered from an uneven hue across the screen. Viewing angle and viewing distance did impact where the unevenness occurred, but no matter where we viewed the display from, we were unable to see an even hue across the display.
Our sample unit did not suffer from any dead pixels or subpixels. As the VH242H is one of Asus's Value-level displays, it is not eligible for Asus's Zero Bright Pixel Defect (ZBD) policy. Asus's warranty page states that "by ISO 13406-2 standards, ASUS conforms to the acceptance spot level which lie between 3 to 5 defective bright/dark pixels." Within the three-year warranty period of the VH242H, Asus will replace the panel if it has more than three permanently-on bright pixels or more than five permanently-off dark pixels.
