Summary: Even if it doesn’t offer the best technologies available, the new BenQ EW2420 is able to provide you good features at a good price. The most important problem of this model is the color rendering in default settings, as it’s difficult to set up. For this price, the device offers an impressive level of black, difficult to find on a low-priced model.
Conclusion: Power Consumption Another benefit of the LEDs compared to a CCFL display is the reduced cost of running them and lower heat output. The EW2420 took only 31 watts to operate at peak brightness, and just 15 watts at minimum brightness. This is around 25% less than comparable CCFL monitors of the same size. While that might seem like a low amount of power, when you run a display for 8-10 hours a day, every day, that can start to add up.
Conclusion: The BenQ EW2420 left us with some mixed feelings really. First of all I thought it would be useful to consider what the LED backlighting actually offered us? The only real benefits of the technology are the thin screen profile, reduced weight and reduced poer consumption. These things are useful of course and are really why LED backlighting is becoming so popular at the moment. However, there still seemed to be a few issues and limitations with the technology.
Pros: Fantastic black depth and contrast ratio, Decent interface options and features, Very competitive price point in sector
Cons: Moderate responsiveness, Viewing angles are ok but not great, Some uniformity issues (may vary)
Excerpt: BenQ's EW2420 is one of a few monitors we've seen to have a VA TFT panel. Unlike standard TN (Twisted nematic) LCD panels, a VA (Vertical Alignment) panel has liquid crystals that naturally align themselves vertically, making them easier to manipulate. VA panels are known for having better black levels, response times and viewing angles, so we were eager to see the EW240 in action. Our first impressions weren't good.
