BenQ EW2430 - Contrast and Viewing angles

Ardjuna Seghers

By Ardjuna Seghers



Our Score:


BenQ is a staunch supporter of AOU's VA panel technology (logical as BenQ owns shares in the panel manufacturer), and that hasn't changed with the EW2430. Generally, VA is inferior to IPS (as found in the likes of the Dell UltraSharp U2410, most notably in the viewing angles department. But it does offer the potential for faster response times and is vastly superior by default to TN. As to the BenQ EW2430 specifically, the positives outweigh the negatives by a significant margin.

As usual, BenQ's contrast claims are a little overstated, to say the least. 3,000 native and 20 million (yes, actually 20,000,000) dynamic is the stuff that even plasma televisions can only dream of, and largely meaningless. However, contrast really is very good, and colours are vibrant without compromising on accuracy.

The otherwise even backlighting is too strong, even at its lowest levels, for blacks to be perfectly black, but you'll only notice if you're staring at a completely dark screen or when paying close attention to the black bars in movies. Tellingly, the EW2430 not only manages to distinguish every dark shade in our greyscale test, but did so without losing detail in whites. This is something that even the best TN-based monitors struggle with, and means you'll see every last detail in movies, games and photos.

Things are helped along by the lack of backlight bleed and some decent, if not exactly flawless, viewing angles. Both vertical and horizontal viewing is inevitably weaker than IPS, but stronger than almost every TN we've come across (with the exception of the amazing panel found in the Samsung Series 9 900X3A), and certainly adequate for daily use.

Vertically, colour shift becomes visible only from the top, which is the least likely viewing position. Horizontally we do see some loss of contrast and colour fidelity at around 165 degrees, but this is already more than you would usually be sitting at. Basically, you can happily view this screen with a group of friends or family without any issues. One minor point worth noting for imaging professionals is that there is incredibly subtle contrast shift even when sitting fairly centrally, though it's so slight it's barely noticeable.

For the price this is the best Monitor on the market, the new PVA panels benq are making are great way better than any TN.

Nec, Eizo and benq are the best monitor manufactures, the rest are rubbish in my opinion.

For what its worth the Dell U2311 sells at a lower price and sports an e-ips 6bit+AFRC to make an 8bit panel, has great blacks, pivots, no SPVA black crush and gamma shift on or off axis.

No mention of the 'inter-unit variability' issues found on the EW2420? A rather long thread on the OcUK forums is filled with issues ranging from excess backlight bleedthrough to 'ripples' and dark patches seen on screen to varying severities.

Of course reviewers always seem to get the cream of the crop!

"Nec, Eizo and benq are the best monitor manufactures, the rest are rubbish in my opinion."

You forget Lacie. I have the 324, bought it two years ago as a replacement for my 22" Iiyama VM 513 and it is a fabulous piece of kit. Expensive yes, but worth every penny. I tried going cheap, it just wasn't worth it for the hit I was taking on image quality when compared to the Iiyama.

Speaking of Iiyama, it is a shame they moved away from quality hardware like the VM513 and decided to churn out the junk they do now.

Dell U2311 is still at £224.34 amazon, you can get one for £20, Benq is still cheaper, i own a PVA and a E-IPS and there is no black crush or gamma shift on PVAs, they are great the only downside compared to IPS is that PVA have some color shift when viewing at large angles.
