At $300, it's difficult to justify buying the 24-inch V2420H. Although it performs well, overall, you can get a superior monitor, such as the Samsung PX2370, for only about $10 more. While the V2420H has some advantages over the PX370--it's one inch wider and has less backlight clouding-- these two assets can't compensate for the V2420H's lacking performance in color. For general use, the V2420H is a fine monitor; however, thanks to its better performance, the PX2370 is worth spending the extra $10.
Design and features
The 24-inch BenQ V2420H has a glossy black chassis punctuated by a light green ring surrounding the power button in the lower-right corner of the bezel. The monitor has a typical-looking circular foot stand that is 7.4-inches in diameter. The stand leaves a 2.8-inches gap from the bottom of the bezel to the desktop and provides adequate stability, as long as you don't touch it. Knocking the monitor from the side caused it to wobble very noticeably. The panel tilts back 10 degrees, but the V2420H doesn't have swivel, height, or pivot adjustments. Its bezel is 0.8-inch wide and the panel is 0.7-inch at its narrowest point and 1.2-inches at its thickest.
The BenQ V2420H has connections for VGA, HDMI, and DVI inputs. The connections are located on the back of the display, in the lower middle and are easily accessible. To the right of the VGA input is a headphone jack.
Under the lower right side of the bezel are five buttons that make up the onscreen display button array. The labels for each function are located above the buttons, on the front face of the bezel. The labels are dull white in color and are difficult to see when calibrating the monitor's settings in a dark room.
The array consists of a Menu button, a Right and Left button, an Enter button, and an Auto button that functions as an automatic calibration when using an analog connection. The Right and Left buttons also double as the preset toggle and audio volume shortcut, respectively.
At first, navigating the OSD was a bit of a challenge for us and it took us a few minutes to become accustomed using the Right and Left Buttons to navigate up and down. The V2420H's preset modes include Standard, Movie, Game, Photo, sRGB, and Eco. Each preset changes the color temperature and brightness of the display with the intent of them being appropriate to the task; for example, Eco lowers the brightness significantly to save on power. Its additional color preset options include Normal, Reddish, and Bluish color temperature options and BenQ provides you with the capability to change the monitor's RGB values individually.

We tested the BenQ V2420H through its DVI input, connected to a Windows Vista PC. On CNET Labs' DisplayMate-based performance tests, the display posts a composite score of 83, which is more than a few points below the Samsung PX2370's 97 score. Particularly, the V2420H has trouble in our various scales tests that evaluate a monitor's capability to show linear intensity progression. In our Color Tracking test, we noticed the monitor's colors have a distinct green tint. In our Black Level test, the V2420H crushes very dark grays to the point that a level four gray--which is four levels above true black--is the darkest color the monitor can display other than true black, indicating that it has a higher than optimal black level. In the Dark Screen test, the BenQ display has less clouding than we found on the Samsung. While the V2420H has clouding at the top and bottom edges on the screen, but its clouding was not as prolific as the PX2370 is, which had more noticeable backlight bleed through.
On the V2420H, we didn't see any color problems when looking at black text on a white background, and fonts were clearly visible down to a 6.8 point size.
We tested the BenQ V2420H using the Blu-ray version of "Avatar." While its colors looked mostly accurate, we did notice a slight green tint on the video. While its Movie preset is the best for watching movies, but its picture detail isn't quite as sharp as it is on the PX2370. Overall, the V2420H's movie playback performance is good, but its color inaccuracy and lack of sharpness keep it from being great.
Because of our intimate familiarity with World of Warcraft, it remains the best tool for us to use when judging color quality and vibrancy in games. We found that the V2420H's Game mode preset grossly over saturates colors, giving the game a particularly garish presentation. However, its sRGB mode is the most appropriate preset for games. While color in sRGB mode isn't as vibrant as it is in the Game mode, the presentation probably won't temporality blind you either. The PX2370 colors are vibrant and tend to pop.
