The ViewSonic VX2250wm-LED is a relatively small Full HD display that packs its 1920 x 1080 resolution into a screen that measures 21.5 inches on the diagonal. The specification suggests that this display is aimed at the mainstream market, rather than the high end enthusiast, as it offers DVI-D and VGA inputs but no HDMI connector or, indeed, a DisplayPort. ViewSonic supplies a full set of DVI-D, VGA cables in the package along with a power cord and an audio cable for the pair of integrated 2W speakers.
The omission of an HDMI connection is fine by us as we consider it to be an AV technology rather than something for the IT crowd, but it means that the VX2250wm-LED isn’t particularly suited for life as a TV display in a student’s bedroom.
Taking a look at the specification of the VX2250wm-LED throws up an interesting feature that you can probably guess from the model code, as this display uses LED backlights instead of the usual CCFL technology. At first glance this doesn’t have much of an impact as the quoted brightness of 250cd/m2 is nothing out of the ordinary and the same is true of the 1000:1 contrast ratio.
ViewSonic quotes a 10,000,000:1 dynamic contrast ratio which is, unfortunately, the sort of thing we expect from display manufacturers where there is an arms race with contrast ratios that start at 15,000:1 and climb into the stratosphere. Even so the figure of 10,000,000:1 seems extreme.
In the past the manufacturers performed similar trickery with response times that dropped as low as 1ms, however ViewSonic appears to have pulled back with the VX2250wm-LED and claims a response time of 5ms.
We’re not surprised to see that the display doesn’t include a USB hub but the absence of a headphone jack suggests that close attention has been paid to cost-cutting.
The styling of the VX2250wm-LED is reasonably attractive, although the clear plastic housing for the power button that sits below the bottom bezel looks unusual. This housing is used to channel light from the orange and blue LEDs that illuminate the button to the front of the panel which diffuses the light and reduces the amount of glare.
We see the benefit of a light that lets us know when the display is in power saving mode, however it remains a mystery that manufacturers such as ViewSonic also use a constant light (blue in this case) to inform us that the display is turned on. You would have thought that two millions illuminated pixels perform this task admirably.
The touch controls for the OSD are fast and responsive, however the two buttons have a number of different functions and we found it necessary to keep a close eye on the OSD messages to figure out what was going on. There is the potential for annoyance as these two buttons are also used to switch between the two inputs. If you only have one input cable connected and then inadvertently press the wrong button, the screen will go dark when you erroneously switch to the unused input.
We were taken aback to discover that the stereo 2W speakers sounded good and were pretty much up to the task of watching movies. You’ll always do better with proper speakers or a set of headphones, but it’s fair to say that the VX2250wm-LED compares very favourably with the integrated speakers you’ll find in other TFTs.
The saving grace for this display are the LED backlights as they make the image far brighter and sharper than the unvarnished figures on the specification suggest. Add in the low price and you’ve got a Full HD display that is a winner.
