Results: Stock Brightness And Contrast
Maximum Stock Settings
Below are the peak light output measurements with brightness turned up all the way. The contrast must be left at its default setting or below, as upping it even one click kills detail in the brightest parts of the image.
Both AH-IPS-based products come up short in maximum white luminance versus more expensive models using older IPS technology.
While the maximum brightness of these monitors is a bit below that of pricier IPS panels, these extremely low black levels more than make up the difference.
ViewSonic comes out on top with a default on/off contrast ratio of 1031.8:1. You’ll notice that we’re now measuring luminance to four decimal places, which makes contrast ratio calculations far more precise.
Both monitors perform very well using stock settings, coming close to their claimed brightness of 250 nits while displaying excellent grayscale and gamma accuracy.
Minimum Stock Setting
Here's what you can expect at the minimum brightness setting. If you work in a dark environment, you can lower the brightness all the way and still have a decent image that's easy on the eyes over long viewing periods.
While these numbers may seem extremely low, they're still well above SMPTE standards for images shown in a completely darkened room. That might seem a little too dim for gaming or productivity, but it'd be pretty typical for watching a movie.
Turning down the brightness control takes the ViewSonic to a supremely low black level of .0633 cd/m2, which is excellent performance for an IPS display.
Of course, contrast ratio suffers at these low brightness settings because the peak output is much lower than 200 nits. Still, all video levels from 0 to 255 are visible at this setting.
Believe it or not, this is still respectable performance. While we don't recommend dropping the brightness all the way, those of you with sensitive eyes certainly could and still see a pretty good image. ViewSonic maintains a decent contrast ratio thanks to the VX2770Smh's low black level.

Unless you're legally blind, why would anyone want a 27" 1920x1080 monitor? I still don't get why one industry thinks we need 1920x1080 on a 5" cell phone, while another thinks 1920x1080 is all the resolution you'll ever need no matter how big your screen.Reply
In other news, Micro Center and Monoprice have 27" monitors @ 2560x1440 for just under $400, both of which are based off the inexpensive 27" Korean monitors but come with a US warranty:Reply
Micro Center - AURIA EQ276W 27" IPS LED Monitor @ $399.99Monoprice - 27" IPS LED CrystalPro Monitor WQHD @ $390.60
Surely that's the comparison readers really want to see. Get on it Tom's!
I bought myself Achieva Shimian QH270-Lite on ebay and it is a 2560x1440 monitor with 6ms response time. Its basically a rejected apple monitor with no frills and no warranty (sold in Korea for $200). I doubt monitor manufactures will release 2560x1440 monitors at mainstream prices within the end of this year, as Intel predicted. Or 4k monitors by 2015.Reply
Here are some links to sites dedicated to these 27" 2560x1440 monitors:

Thanks for the review. These do look like very good choices for those that don't need a gaming monitor. No offense to this review as I do think it serves a purpose and will be useful to many. However, I think I'm going to quit reading monitor reviews for a couple of years. Maybe by then my 15 year old monitor and my 10 year old ~$500 LCD will be surpassed by something new and better.Reply

Sony PVM2541 25-inch Professional OLED Picture Monitor
Pass. 27'' is way to big for 1080p, needs 1440 at the minimum.Reply
Manufactures need to stop making 1080p monitors. With 4k around the corner, it should be at least 1440 or 1600 now. Were not gonna get anywhere until someone finally starts to really mass produce higher res monitors
Remember when CRT's supported tons of resolutions and refresh rates, more than most could handle? Then trendiness and HDCP got in the way.Reply

Still 1080p, pass.

It's a 24" monitor, what did you expect? (they market it at 25" but it's really 24 5/8")
If they come out with a 27-30" monitor, surely it'd be 2560px wide since they are professional-level displays.
