Monitor testing is usually subjective and differs from person to person, but there are a few technical tests that can prove a monitors worth. In these tests, the resolution is set at 1920 x 1080 @ 60Hz, and photographed with an Olympus E-1 in a completely dark room. Every photograph below are at the same exposure values.
This image was used to select the best exposure values in order to clearly show the contrasts between light and dark, as this is difficult to represent in photographs.
This first test is just a screen of black, and shows the amount of backlight bleeding on the panel. The panel shows completely black, which is a product of the backlight dimming. Even when I pushed the exposure all the way up in RAW, there was very little backlight bleeding. This is very impressive for an LCD panel.
This is just a screen of white. This would show any dead pixels as well as how bright the panel can be. The faint border around the screen is just the reflection off the beveled edge, and is not noticeable in person.
These tests show the contrast of the monitor. Each shade of grey should be easily distinguishable from each other, which is true for this monitor. The picture does not do it justice because of the limited dynamic range of the camera sensor, but to the human eye, the contrast is perfect.

To gamers especially, ghosting is a very important characteristic to LCD monitors. CRT monitors usually do not suffer from ghosting because each pixel refreshes very quickly, but in LCD monitors, the pixels turn on and off slower and if it is slow enough, ghosting appears. These images of a car moving from right to left were captured at 1/60th of a second. The monitor was outputting at 60 frames per second, so this is the equivalent of one frame. As you can see there is no ghosting, the PX2370 performs much better than all the previous monitor. The moving car demonstrates how long a pixel stays lit after it has changed, and Samsung has managed to make the PX2370 much faster than its predecessors. This is one of the best monitors I have seen in this respect, which should make FPS gamers rejoice if they decide to purchase.
