OSD and Initial Readings

The OSD for the AOC does a good job and has all the controls available that you need. In making my initial settings and measurements, I noticed that the selection of the sRGB color setting really reduces the level of light output from the display. Since the sRGB standard calls for a specific level of light (120 nits), this is actually a reasonable thing to do as pushing the backlight level to be really high can cause color shifts on displays. From the OSD I was able to configure everything I needed for the display, including a single custom white balance control that I used later to set the 100% white value as close to D65 as possible.

For the AOC review, I made a couple of changes to the equipment used for reviews. I have added a new i1Pro spectrometer to my testing equipment, and so it will now be used for all monitors reviews I do going forward. This meter has also recently been tested in the NIST approved lab by SpectraCal to ensure that it has an average dE of only 0.4 and a maximum dE of 1.0 across the color spectrum. Spectrometers are also much less susceptible to drifting over time than a tristimulus meter (e.g. the i1Display2) would be.

The downside of the i1Pro is that it does not do a wonderful job with low light levels (below 20% stimulus), and so for the dark uniformity and brightness uniformity measurements I will continue to use my i1Display Pro meter instead. The color accuracy might not be as good as the i1Pro, but the light level readings are better for these tests. Hopefully in the future I will be able to profile the i1Display Pro using the i1Pro, which would provide the accuracy of the i1Pro with the speed and low light handing of the i1Display Pro. Because of these changes some of these dE readings might look better, or worse, than you would expect, but these new numbers will be more accurate going forward.

Color Tracking -  XR Pro, Xrite i1D2 and XR i1DPro

Uncalibrated, the AOC has a dE of right around 5 in the sRGB mode. This number looks very good compared to other monitors, but remember we are using newer, more accurate test equipment and the only other display on the chart measured with this is the HP LA22f. The worst part of the uncalibrated result is that the largest error occurs with pure white, which you are likely to have on your screen a fair amount of the time. Overall, however, this is a good number to see. Hopefully the calibration can further improve on this, but starting out at a dE of 5 is very nice.

    Ok. Thanks for the info. So I'll still keep my Dell WFP2007.

    I really want someone to release a 120Hz IPS with 1920x1200 resolution.

    When I read these monitor reviews I often see a great deal of info on color calibration, contrast etc. but would it be possible to add a new metric to the reviews?

    I am specifically interested in text clarity and eye strain.
    How would a given monitor compare for reading/heavy text usage?

    As a developer I spend an incredible amount of time in front of the screen. I'm not sure what metrics correlate to a "good" viewing experience but a test around such criteria would be fantastic for the office workers and monitor jockies among us.

    I have 7+ diff. monitor models at my office. And have found that some monitors are much easier on the eyes than others. We have a particular 22inch Dell IPS (about 5 years old now) that I would rate the best, but can't tell you what qualities provide such a comfortable viewing experience. There are other IPS monitors that do not match it, its pixel density is avg among our models, etc.

    Would something like this be possible?

    Thanks for another great review,

    I have two of these monitors which I use for C# and asp.net development along with web design. My gold standard are my Dell PVA 24 inch monitors (I now have six 2408 monitors in total) and I also have 2 Dell IPS monitors (U2410's). I reject TN monitors as unusable for every day programming and design work.

    I was concerned that text would appear fuzzy because these are e-IPS monitors, but in daily use I see no significant difference between this monitor and my U2410's.

    The LED back-light does provide higher contrast but after calibration I still prefer my U2410's. For programming I like to rotate my monitor display by 90 degrees, and I usually have 3 of these lined up side-by-side or two in the vertical and one in the horizontal attitude. Unfortunately the AOC monitor cannot be rotated and does not have height adjustment. However the monitors run incredibly cool and I am using them for web development.

    My criteria (for work usage) is:

    Viewing angle
    Banding and color accuracy
    Ergonomics (adjustment potential)
    Eye strain and headache issues from long term use (>18 hours per day)

    Relative to my Dell monitors, the AOC scores 9, 8, 3, 10 respectively. Against this, the best 120Hz TN monitor scores 2, 7, 9, 2. So I would say they are worth the price bump over TN for office and extended work usage.

    I really wish they came as 24 inch monitors but on the odd occasion I watch media content the AOC is close to ideal. I have no ghosting on my displays (I use only the 2 hdmi connectors of course).

    I still prefer my 2408's for day-to-day use, and until the AOC's arrived I considered the U2410 / Z24 to be the ideal compromise monitors. Despite ergonomic limitations the AOC is an excellent display and I will be buying more of them (I have 3 separate work stations in daily use). They set the minimum for acceptable workstation display IMUO.

    Any plans on reviewing the LG IPS236V or HP ZR2440w?
  • svojoe - Saturday, March 3, 2012 - link

    As per this article, I decided to buy this monitor.

    But I've had some problems, I have my second one now and I cannot get any display to show up on HDMI, I have tried 2 different cables and 3 different computers (two intel HD3000 and one ATOM/ION netbook) and I get nothing. I get output on VGA but not HDMI. AOC engineer told me I had a dud to RMA it. I did and my replacement is here doing the exact same thing. I need this monitor for a time sensitive deadline project and not having the extra screen space is hurting me.

    No a single word on the net about problems with this monitor. But something us up for me to get two ;(

    After a day of tinkering I was able to figure it out. Its a windows 7/Intel HD driver issue. Default settings on Win7 Display modes would not allow it to be detected until i deleted all drivers for display and really messed around with the 'projector/external display settings'. Now it shows up.

    and it LOOKS AMAZING!

    I want to buy this monitor but some say it has blur in FPS which I play all the time. but I really like this monitor is it possible to adjust the vertical and horizontal refresh lines to prevent blur ?

    please advise from people have this monitor I dont have another IPS choice near my place.

    1. When plugged into a switched outlet, can it be made to power up without having to press a power-on button?

    2. Can the speakers be made to work with the digital audio from the HDMI cable?
  • chamilafernando - Saturday, October 20, 2012 - link

    Can someone confirm me this actually have an audio output please ?

    Hi! I've been looking for an external monitor for my MacBook Pro 13-inch Early 2011. Would this be a good monitor for my computer? I'm looking for a monitor that will display extremely crisp text, display accurate colours (vibrant colours) and doesn't lag when watching videos. I don't want ghosting or any bleeding either. Would this be a good monitor?
