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.

The SA750 is on hand and up for review soon, though probably behind a couple of other panels that are already here, one of which is TN.JMS3072 - Thursday, October 13, 2011 - link
Can you speak to the volume of the headphone jack when using high-impedance (32Ω or greater) headphones?cheinonen - Thursday, October 13, 2011 - link
I can't right now but I can try to hook them up tomorrow and give it a quick listen. The headphones I have on hand are 32 ohm (Grado SR60) or AKG K701s that are a huge pain to drive, and I'm certain it won't be able to do a decent job on at all. I will try with the Grado's and see how it does, though. I focused more on the speakers than on the headphone output.cheinonen - Friday, October 14, 2011 - link
I got a chance to hook up my Grado SR60s to the BenQ, playing back a Blu-ray over HDMI. Even with the volume cranked all the way up it really wasn't that loud, much quieter than I would expect. If I had headphones that were hard to drive, I certainly wouldn't count on it putting out a decent volume level.ncomben - Thursday, October 13, 2011 - link
What is it with all these 16:9 monitors - can we have at least have reviews of proper monitors for PC users who do more than just watch films or play console games?I believe the panel makers are doing the public a great injustice in the name of reducing costs and standardising across markets. I can almost understand reviewing below 24" at 16:9 since the headline resolution sounds better than a 16:10 screen much better but at 24", come on...
I'm a developer and, I would argue that the 22" 1680x1050 monitors I am currently using are vastly superior to use than the newer tiny 22" 1920x1080 screens that my company buy for new developers.
I use a 16x10 24" at home for gaming, development, films &, browsing and it's perfect.
We recently got a 27" in the office to try out... it's going back because nobody could read the fonts!
Then again, perhaps it's just me?

That makes no sense....."I'm a developer and, I would argue that the 22" 1680x1050 monitors I am currently using are vastly superior to use than the newer tiny 22" 1920x1080 screens that my company buy for new developers."
Absolutely no sense when you have less verticle resolution. I'm getting a bit sick of hearing this debate 16:10 vs 16:9, Sure, some people will prefer the extra verticle resolution of 1920x1200 vs 1920x1080 but the ratio argument fails if you prefer a 1680x1050 over a 1920x1080.
Resolution matters, ratio does not. It makes no sense to prefer a smaller res just to get 16:10.
And I agree about testing the SA750/SA950. They are very nice monitors and have better colour reproduction than mainstream IPS monitors.

The real problem isn't 16:10 or 16:9.the real problem is, that 4:3 and 5:4 are dead, especially in larger than 19 inch screens.
I'm looking for an excellent 1600x1200 screen to get three of, and use them in portrait mode, but it's almost impossible, because the Eizo s2100k is apparently the only high quality display that's not costing an arm and two legs, while still offering reasonably thin bezels and usb-auto-calibration. Sadly, that screen hasn't seen a refresh for more than 6 years, and only old stock is being sold.
At that size and resolution it's also unpractical to go for single displays, and even a good 30 incher is already more expensive - and also going the way of the dodo.
Seems like screen real estate isn't that sought after anymore :(

Dell is still selling their 20" model 2007 LCD which is 1600x1200, but it's $399, i.e. the same price as a Dell 1920x1200 24" IPS monitor.imaheadcase - Thursday, October 13, 2011 - link
It does make sense in a personal experience aspect. Once you use a 24inch 1920x1200 using a x1080 just "feels" wrong. You fill ripped off. Games especially. It just feels the screen is tearing.kmmatney - Thursday, October 13, 2011 - link

I work in 1920 x 1200, but if I had a choice, I'd pick a 22" 1680 x 1050 screen over 1080p (for work). It makes sense if you spend all day trying to work with the 2 resolutions.
