BenQ VW2420H Monitor Review
by Chris Heinonen on December 10, 2011 2:45 AM ESTInput Lag and Power Use
With the lag tests, the BenQ performed adequately, offering around 1 frame of lag overall in testing. Changing the refresh speed did nothing to alter these numbers either, so 15.3 ms of lag is about what you can expect from this display. I didn’t find it distracting or bothersome in the gaming I did, but if you want the lowest lag possible you’ll still need to look for a different panel type.
The peak power use for the BenQ was pretty average for the size, with 36 watts used at full backlight power. At minimum backlight, that dropped down to 16 watts, which isn’t as low as many other displays are able to achieve at this point. Our database doesn’t have enough *VA panels to let me be certain if it’s the panel that requires more power or something in the design of the monitor, but the difference is only 4-5 watts over the best performing monitors. [Ed: Which, sadly, is probably why we're not seeing this sort of display in a laptop.]

+1This is a high-end site. I'm not clear on why anyone here would buy anything but either:
1. an excellent s-ips screen
2. 120hz input screen
Also, Chris, please do not encourage people here to purchase a "3d" TV as a monitor. As you *must* know, there is no TV on the market today that can accept a 120hz signal and display it, and most TVs have *horrible* input lag. To even suggest that a 3d tv is an acceptible monitor is to further confuse an already confused public.

For the most part sites review what vendors send them for review.gmkmay - Saturday, December 10, 2011 - link
Just out of curiosity why would you review this when you already reviewed the EW2420? They use the same panel with just slight differences in inputs and presentation. The time spent reviewing this seems like it would have been much better spent reviewing the 750d Samsung TN 120hz monitor that you've said was forthcoming.cheinonen - Sunday, December 11, 2011 - link
BenQ provided both and I reviewed both of them. The Samsung is coming very, very soon.jmunjr - Saturday, December 10, 2011 - link
Same old story. LCD makers, if you keep making 16:9 LCDs many of us will run the other way... We don't care if it is cheaper, we want better.seapeople - Saturday, December 10, 2011 - link
I want 16:16 aspect ratio, I really like my vertical space. Actually, I'd prefer something like a 9:16 aspect ratio, but I just don't think we'll ever get there.Penti - Saturday, December 10, 2011 - link
Haha, you mean you like to pivot your screen? Just do it.JediJeb - Saturday, December 10, 2011 - link
With the lack of VESA mounts these days most monitors won't pivot unless you tear them apart and use some sheet metal screws to mount them to a post.TegiriNenashi - Monday, December 12, 2011 - link
Yes pivot that 16:9 screen to see how ridiculously narrow it is.
