BenQ EW2420 Monitor Review
by Chris Heinonen on October 13, 2011 12:00 AM ESTColor Uniformity
The overall color quality of the BenQ was just acceptable with a dE of slightly over 2, and that isn’t limited to the center. Color quality is best at the center and middle-bottom of the screen, with the error level getting higher at the top and corners of the screen.
This is a pattern that we will see repeated when we get to the brightness uniformity charts as well. Most likely this is caused by unevenness in the LED backlighting across the screen, which influences the color quality as a result. With a dE that doesn’t fall below 2 anywhere on the screen, the BenQ isn’t a display that can be recommended for serious print work, but for day-to-day use it should be good enough. As with most displays the highest dE errors occur in colors that are a majority blue, and these errors are less visible to the eye than if the colors were mostly red or green. Grayscale tracking was very good overall, and that’s the most important element of image as far as human vision is concerned.
Color Gamut
The BenQ EW2420 has LED backlighting but still only covers the standard sRGB colorspace and not the AdobeRGB space. We see in the gamut chart that it covers around 70% of the AdobeRGB space, which is average. This also contributes to the higher dE values as some of the color samples used in that test fall outside of the sRGB gamut.

Can you guys review the new Samsung SA950? Heard it was a great 120hz monitor with very good colors for a TN panel.Operandi - Thursday, October 13, 2011 - link
I'll throw my 2 cents in by saying please don't bother reviewing any TN panel.EnzoFX - Thursday, October 13, 2011 - link
Agreed!wicko - Thursday, October 13, 2011 - link
Next time you should keep your 2 cents.GeorgeH - Thursday, October 13, 2011 - link
This. TN panels have their place, especially in a market overflowing with 120Hz IPS screens.Next time try replacing 'TN' with '27" 1080p'. ;)

Here's a universal review for any TN panel: buy the cheapest panel in your desired size. It will suck. If you don't notice it sjkostans - Thursday, October 13, 2011 - link
Yeah unless you're talking 120Hz which is a completely different story. There are people out there that aren't satisfied with 60Hz for gaming.wicko - Thursday, October 13, 2011 - link
Yeah because there is only one quality of TN panel: crap.We get it, you're a panel snob, move along.

I can't tell if you're being sarcastic or not, so I'll ask- What 120Hz IPS screens?dqniel - Thursday, October 13, 2011 - link
Some people require 120Hz panels for competitive gaming. Not everybody's needs will be met with a PVA or IPS panel.I'd also love to see some 120Hz panel reviews/comparisons.
