BenQ VW2420H Monitor Review
by Chris Heinonen on December 10, 2011 2:45 AM ESTConclusion: Good with Caveats
With the VW2420H, BenQ has removed a lot of the extra features like multiple HDMI inputs that were on their EW2420 display, and at the same time they've managed to increase the already superb contrast ratios. The main negatives for the BenQ in my book are the total lack of adjustments beyond tilt, which you can’t remedy with a different stand due to the lack of VESA mounting holes, and the OSD interface. BenQ needs to update the OSD so that all menu selections are horizontal or vertical, and not a combination, unless they want to add a 4-way pad to the front of the monitor. It’s easy enough to fix, and it will make the OSD far more usable.
While there are some good results in our testing, just looking at the uniformity testing makes me hesitate a bit about the BenQ. Overall I think it's a good display, and the color quality is decent after calibration; however, color accuracy drifts heavily at the edges, along with the white uniformity. Still, the contrast ratio is outstanding compared to everything else in our test database.
Right now you can find the BenQ VW2420H online for $250 at Best Buy (plus tax and shipping), which is up to $80 less than what you'll pay at Newegg. It's a reasonable price for a better-than-TN display, though if you're after faster response times or a 3D-capable panel you're pretty much stuck with TN right now (or spring for an HDTV).
I really enjoyed the BenQ from the time I hooked it up until the time I boxed it up, which can’t be said for most things that I review. I wish it was a little cheaper, with more uniform color, and had a better stand for what it is selling for online, but the performance is enough for me to recommend giving it a serious look for a desktop display.

BenQ's website says this monitor has an 8-bit panel with 24-bit interpolation. I don't understand why interpolation is used for a panel that's capable of displaying 24-bit color. Could someone explain this, please?marraco - Saturday, December 10, 2011 - link
If I need a machine to tell the color accuracy of a monitor, well, then I don’t care much about it. I’m not sensible on color accuracy.But If I read an Anandtech article about a monitor, then I buy the monitor, and text looks blurry when I scroll web pages, PDF, and word documents, then I blame the Anandtech article which said NOT A WORD about things that matter.

Man, I couldn't agree more. I'm not sure who these reviews are for. There are so few people that really care about color accuracy.- input lag
- 120hz
- ?? what else matters? I'm personally a little hazy on why any gamer would settle for 60hz when 120hz is just *so* much better.
Now that I think about it, my guess is that the market for people who care about quality monitors (ie, people that know anything at all about displays) and who *aren't* photographers/graphic artists must be vanishingly small, which is why the reviews seem to cater to that crowd.

There are people who care about color accuracy and those who care about input lag, and those who care about both. I can't venture to assume what percentage of people care about which unfortunately, though I care far more about color accuracy than input lag myself as I rarely game but do a lot of image and general work where the colors annoy me. However, I know I don't represent everyone so I try to cover everything I can.The next display up is a 120 Hz display, so there will be comments on that of course. I'm attempting to find a better way to measure the actual motion resolution on displays, but have run into a couple issues on that so far:
- The test patterns max out at 1920x1080
- The output is limited to 60 Hz
So the 120 Hz display can't take full advantage of the panel for that. I'm trying to find a way to measure that better, as motion resolution is something that is hard to really get across right now.
I'm trying to cover all the bases for reviews, and trying to clear out the backlog of monitors that are here so I can start to better select what the comments are interested in.

60 Hz monitors give me eyestrain every time. My next monitor absolutely has to be 120 Hz or higher.Zan Lynx - Monday, December 12, 2011 - link
Exactly how does the refresh rate on a LCD cause eye strain for you? I can see that with a CRT it would because the low phosphor persistence on high refresh rate CRTs would cause flicker when used at a lower refresh rate.With an LCD the pixel stays set until the displays gets a refresh. It doesn't flicker. At all.
You might be seeing a 60Hz flicker of the LCD's fluorescent backlight tubes. If that is the problem, then you need to find a monitor manufacturer that uses a better backlight..
It could also be caused by your eyes being badly affected by interference patterns generated by room fluorescent lighting flicker combining with LCD backlight flicker.
In none of these cases will a 120Hz refresh LCD solve your problem except by a new display coincidentally using a different backlight.

I thought my new LED LCD laptop would finally get rid of eyestrain forever, but I was very wrong. Just passing my fingers across the screen reveals obvious flicker. Without getting into deep technical analysis, the bottom line is this:I can stare at a tree in my yard and never get eye strain/fatigue, but staring at my new 60Hz LED LCD gives me eye strain/fatigue every time.Oxford Guy - Tuesday, December 13, 2011 - link
Next-generation panels from the maker of the panels used in these BenQ monitors are being produced and are about to be produced:http://www.tftcentral.co.uk/news_archive/25.htm#au...
Some have a 5000:1 contrast ratio rating (up from 3000:1). Some are 120 Hz. They have a faster response rating of 6 ms g2g rather than 8 ms, and 12 ms overall rather than 25 ms.
The first announced panel that appears to use one of these is the Phillips 241P4QPYEB/27 and 241P4QPYES/00. The only difference between the two is the color of the frame.
