We put the Asus MK241H through some color and text reading diagnostics using Everest Ultimate Edition from Lavalys. 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 MK241H set to its factory defaults as well as with a few tweaked settings to optimize the display. The 2243BW 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 nearly all 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 significant light spillover from the backlight.
The monitor was not perfect, however. A slight moiré pattern was noticeable on the dots test, and the moiré pattern got even worse on the vertical and horizontal lines tests. Additionally, the MK241H didn’t make it out of all of the solid color tests screens completely unscathed. Both the orange 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 a complete, even hue with either test screen across the display.
During testing, we also noticed a total of four dead subpixels on our unit. Three were in the lower-right corner and one was in the lower-left corner. The MK241H's warranty allows you to exchange the monitor if it suffers from even just one bright pixel within the first year of ownership--what Asus refers to as its Zero Bright Pixel Defect (ZBD) policy. Our unit, however, had three dark subpixels, which wasn't applicable in this case. Asus's warranty page on its Web site reads as follows:
"By ISO 13406-2 standards, ASUS conforms to the acceptance spot level which lie between 3 to 5 defective bright/dark pixels. In order to deliver ultimate vision experience to ASUS customer, if your panel is less than or equal to the above number of spots, then, it is considered as an acceptable LCD monitor."
Going by this, since we had four dark subpixels, it was not clear if our unit would be eligible for replacement under the warranty or not. However, a chart on Asus's site further clarified the details, informing us that our unit was one bad pixel shy of being eligible for an exchange:
