AOC I2757Fh And ViewSonic VX2770Smh: Two 27" IPS Monitors

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.

  • 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:

    Micro Center - AURIA EQ276W 27" IPS LED Monitor @ $399.99
    Monoprice - 27" IPS LED CrystalPro Monitor WQHD @ $390.60

    Surely that's the comparison readers really want to see. Get on it Tom's!

  • 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.

  • 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.

    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.

    They already have been surpassed, but the tech is expensive currently:

  • Pass. 27'' is way to big for 1080p, needs 1440 at the minimum.

    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.

    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.

  • Nuts to that1920x1080?Next.

    I don't see many people complain about their 60" 1080p TVs.
    60" is waaay bigger than 27". Maybe sit just a tiiiiiiiny bit further from your screen?

  • 5Ms aoc is good for gaming monitor at low cost.
    please put the information how much mhz it can handle (to compare good gpu for that) .
    15" aoc run at 300mhz in aoc monitor software.

  • Aoc monitor low cost and 5ms but viewsonic 7Ms and high cost. but both give 3year warranty.

  • PC monitors are a dying bread for the common home user. I switch to an HDTV with 120Hz... the only drawback is input lag... man I didn't see this one comming especially at 1080p.

    It's not bad at all for single player games, but if you play Counter-Strike intensively, maybe not a good idea. But anything other than FPS online is not a real matter.

    Get a good Samsung HDTV and get rid of the office. There is some awesome logitech products for input device that let you transform your desktop into a gaming HTPC.

  • I just got an Auria 2560x1440 two weeks ago and I could never go back to 1920x1080 now.

  • I also just got an Auria 2560x1440 last week, and I could never go back to 1080 either. The Auria dominates! Shreddder style

  • Didn't know this site was full of tech gurus with deep pockets. I will go for this 27" never mind that it's "only" 1080p - I need TV replacement and this will do just fine, especially being IPS panel for such a low cost. Heck even my ASUS 278Q or whatever model is dearer. Any 2560x1440 monitor that is not made in meat factory would cost nearly twice as much so.. Until 4k becomes standard I am fine with 1080p.

  • I bought myself an Auria for Christmas - it's awesome. Huge, bright, crisp, and not one dead pixel. For $300 less than DELL/HP and $600 less than Apple's product using the same LG IPS panel.

  • Can anyone with those Auria screens comment on if they have noticeable off angle glow?

    Image of an Asus(I know it was e-ips, but it was BAD, even TN did better then this thing. This was MAX bright vs 26% on the other screen) I had next to a Samsung S-PVA. The glow was extreme even at slight angles and the card color reproduction was just awful.

  • ....or spend the same money on a 1440p LG panel by one of the thousands of manufacturers out of Korea or China (or Overlord here in the states) instead of wasting your money on old, out-dated tech.
