We put the Samsung 2493HM 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 Samsung 2493HM set to factory defaults and the display set to the "custom" preset, which is supposed to be factory calibrated for optimal all-purpose viewing.
For the most part, the 2493HM performed well on all of the tests. The 2493HM did a great job on all of the grid and text reproduction tests, producing sharp and clear text, like all LCDs should. It also did a good job in the color and gradient tests, or at least as good as any TN panel we have seen.
In each of the solid-fill tests, the screen displays a single uniform color. In all of the solid-fill tests, we noticed the top of the screen appeared to be slightly darker than the bottom. This was especially noticeable in the orange solid-fill test. This is a characteristic of the TN panel technology used by the 2493HM. It results from the panel's relatively poor color-accurate viewing angles. While TN panels offer plenty of usable viewing angle in both the horizontal and vertical directions, they generally offer extremely poor accurate viewing angles, as proven by the solid-fill tests.
The 2493HM didn't have any trouble with the grey and white solid-fill tests, but the black solid-fill test revealed slight back-light bleed along the sides of the screen. The back-light bleed is is minimal and barely visible. The color palette tests weren't a problem for the 2493HM, considering the panel technology in use. As with nearly all LCDs based on TN panel technology, the 2493HM suffers from a relatively low color gamut and doesn't offer full 8-bit color processing. This shouldn't be a problem for gaming, multimedia or everyday office use, but it could be a problem for professional graphics work, where color accuracy is important.
