The HP L2151ws is an excellent 21" widescreen LCD monitor with a maximum resolution of 1920 x 1080 for full HD playback. The thumbnail-thin and compact but stylish appearance and lack of real estate requirements on your desk makes it a particularly good option for those looking for a good sized widescreen monitor without unnecessarily cluttering your work space.
A responsive 5ms display allows for superior performance in all manner of applications, from day-to-day use, graphic design and gaming and with a wide selection of configurable options through the built in on-screen display customising brightness, contrast and many other features is possible, although as with many monitors it may take a few moments to be accustomed to the controls in order to do this as the functionality isn't quite as intuitive as one would hope for.
The only true drawback I have found is that the supplied AC adapter and power cable seem to be of a poor quality, with the power cable easily being dislodged through accidental knocks which could present a potential hazard and therefore all prospective owners would be well served keeping the adapter in a ventilated location as far away from feet, pets or moving chairs as possible.
For the price most users will be very happy with this purchase and it is more than capable of dealing with high-end computing and gaming tasks.
