The pearl-white finish of the ViewSonic VX2451Mhp-LED immediately sets it apart from the multitude of grey or 'piano black' 24in monitors currently on the market.
It looks great in a home environment where its bright exterior causes it to look considerably smaller than its 24in screen would lead you to expect. As such, the ViewSonic VX2451Mhp-LED doesn't have that imposing appearance that might put you off attaching a large-screen monitor to your PC. See also: Group test: what's the best display?
If this doesn't sound like your cup of tea, fear not, there's a black version of the ViewSonic VX2451Mhp-LED, too.
It's a 1080p-capable HD display which will connect to a variety of sources via its VGA, DVI-D and HDMI inputs. A pair of speakers with 2.5W amplifier is built into the ViewSonic VX2451Mhp-LED's bezel which can be driven either by the supplied analogue input jack or via HDMI, making the display suitable for light multimedia use.
Featuring a matt 3H hard coating, the ViewSonic VX2451Mhp-LED display diffuses reflections well, so you won't have too much trouble dealing with anything from sunlight to overhead lighting.
Specification-wise, the ViewSonic VX2451Mhp-LED is nothing to get too excited about. It produces a punchy, colourful picture with an impressive amount of contrast, but suffers from the usual pitfalls associated with the lower-cost TN panel technology it uses.
Narrow viewing angles mean the picture won't appear consistently bright across the whole screen and head movements create small perceived shifts in brightness and colour.
Furthermore, there's a very noticeable amount of backlight bleed along the top and bottom edges of the display. Set your PC's desktop background to black and this becomes immediately apparent.
However, the display is rightly somewhat proud of its green credentials. It has a mercury-free construction with zero electromagnetic radiation and boasts a power-saving LED backlight.
The LED backlight also contributes to the panel's slender proportions which are enhanced still further by the use of an external power supply ‘brick' to save space inside the casing.
The display's control buttons together in the middle of the bottom of the monitor, forming a silver letter V shape around a larger white power button which is optionally illuminated by a customary blue LED.
After many years, ViewSonic has finally updated its on-screen menu system with something much more modern-looking and easier on the eye. However, the same button “1” and button “2” control interface of old is used to access it, which still takes some getting used to.
In this case, the buttons are also very small, and when placed this close together menu operation can become rather fiddly.
Advanced menu options include the ability to turn on the dynamic contrast mode, which thankfully defaults to ‘off', and also three levels of response time adjustment – which we found to make no noticeable difference.
ViewSonic VX2451Mhp-LED: Lab results
Our Spyder3 calibrator tests revealed the VX2451mhp-LED to have solid but unremarkable performance. Much as we would expect from a TN-based display at this price in fact, although contrast results were somewhat better than we're used to.
We measured 71% of the Adobe RGB and 91% of sRGB colour gamut. Maximum brightness was 258cd/m2 uncalibrated, while contrast ratio was a strong 801:1.
As we were hoping, power consumption figures were rather impressive. At maximum brightness we measured a power draw of just 19W which fell to 13W when we lowered the brightness to 120 cd/m2. As if this wasn't good enough, ViewSonic has included three levels of Eco mode. Selecting the most frugal ‘Conserve' mode shaved off an additional watt, but also dimmed the screen to just 89.77 cd/m2 which we still found quite comfortably readable for text.
