We tested the Samsung PX2370 by connecting it to a computer via its DVI connection. The PX2370 earned a composite score of 97 on CNET Labs' DisplayMate-based performance tests, besting the XL2370's score of 96. The PX2370 did a better job distinguishing very dark gray from black than the XL2370; however, unlike the XL2370, the PX2370 oversaturates very light gray. Also, the PX2370 allows slightly less light through its screen than the XL2370 did on our Dark Screen test. Overall, the two monitors performed similarly in the tests, with the PX2370 having a slight edge in many tests.

The PX2370 achieves a brightness score of 246 candelas per square meter, which is much lower than the XL2370's 344 cd/m2 score. As a result, the XL2370 also achieved a higher contrast ratio--thanks to its higher peak white measurement--than the PX2370 did; 1,008:1 to 948:1, respectively.

We used the PX2370's Cinema preset to check out "Kill Bill: Vol. 1" on DVD as well as several 1080p movie files from Microsoft's WMV HD Showcase. In both "Kill Bill" and the 1080p movies, we found that the PX2370 colors were more accurate and vibrant than the XL2370's. In a side-by-side comparison, red on the XL2370 looked closer to orange when compared with the deeper red we saw on the PX2370 in the same scene.

While playing World of Warcraft and Unreal Tournament 3, we didn't notice any signs of input lag, streaking, or ghosting during fast movement. We found that the PX2370 and XL2370 looked virtually identical when displaying the games. However, thanks to its Magic Angle feature, the PX2370 has a performance advantage when viewing from off angles.

The optimal viewing angle for a monitor is usually directly in front, about a quarter of the way down from the top of the screen. At this angle, you're viewing the colors and gamma correction as the manufacturer intended. Most monitors are not made to be viewed at any other angle. Depending on the panel type, picture quality at nonoptimal angles varies. Most monitors use TN panels, which get overly bright or overly dark in parts of the screen when viewed from nonoptimal angles. The Samsung PX2370 uses a TN panel, and when it is viewed from the sides or bottom, we perceived the screen to darken about 6 inches off from center.

The Magic Angle mode prevents the screen from darkening when viewed from certain angles. Magic Angle has four settings: Lean Back Mode 1, Lean Back Mode 2, Standing Mode, and Side Mode. Switching to each mode will improve screen brightness when viewing the monitor from that angle. For example, after switching to Lean Back Mode 2 and then sitting back in your chair to play a game, the screen doesn't darken nearly as much, and as a result, game details can still be seen, while you do irreparable damage to your spine.

In our power consumption tests, the Samsung PX2370 has an On/Default power draw of 25.01 watts, which is 5 watts lower than the XL2370's 30.09 watts. With a calibrated brightness of 200 cd/m2, the PX2370 draws about 20 watts, compared with the 21-watt draw of the XL2370. However, standby power draw is where contests are won. The PX2370's standby power was a very low 0.27 watt, compared with the XL2370's 1.42 watts. Based on our formula, the PX2370 would cost $7.65 per year to power; the XL2370 would cost $9.96 per year.
