Results: Gamma And ANSI Contrast Ratio

Auria EQ276W 27" IPS Monitor Review: QHD For $400
By

Gamma is the measurement of luminance levels at every step in the brightness range from 0 to 100 percent. This is important because poor gamma can either crush detail at various points or wash it out, making the entire picture appear flat and dull. Correct gamma produces a more three-dimensional image, with greater depth and pop. Meanwhile, incorrect gamma can negatively affect image quality, even in monitors with high contrast ratios.

In the gamma chart below, the yellow line represents 2.2, which is the most widely-accepted standard for television, film, and computer graphics production. The closer the white measurement trace comes to 2.2, the better.

The EQ276W tracks fairly well from zero to 100 percent. The overall picture shows an average value of 1.98 with a dip to 1.86 at the 10 percent level. The highest value in this measurement is 2.03 at 80 percent. The visible result is an image that looks slightly washed out, especially in the lower luminance levels. While not too grievous, it’s less accurate than other IPS monitors we’ve tested.

Gamma value range shows the quality of tracking from zero to 100 percent. A flatter gamma trace is obviously more desirable.

The Auria places smack in the middle of our five-way comparison, but its score is very close to the top two performers. You can see both from the gamma trace and the low range that the EQ276W’s gamma tracking is actually quite good.

It’s unfortunate that the Auria doesn’t include a gamma control. That’s all it would take to pull it out of last place in our comparison. Image quality would be noticeably improved if the user could raise the already-flat gamma to the correct level of 2.2.

ANSI Contrast Ratio

Another important measure of contrast is ANSI. To perform this test, a checkerboard pattern of sixteen 0 and 100 percent squares are measured. This is somewhat more real-world than on/off measurements because it tests a display’s ability to simultaneously maintain both low black and full white levels, and factors in screen uniformity. The average of the eight full-white measurements is divided by the average of the eight full-black measurements to arrive at the ANSI result.

Auria’s ANSI number is only slightly below its on/off result. This is very good performance. If you compare the other IPS screens in the group, you’ll notice their ANSI ratios are significantly lower than their on/off results. The conclusion is the EQ276W will present consistent image quality regardless of content.

    I love My Auria, I also did buy a another stand for it. It was $29.99 on Amazon, and once I got everything set up, IT IS AMAZING!!!!! If you want a great product for the right price, DO IT!

    BigMack70One important thing to mention that you guys didn't that I believe still holds true (haven't checked the competition in a couple months - someone correct me if I'm wrong here): this is the only model of this panel (as opposed to the Catleaps/Crossovers/Overloards/Achievas/etc) to have HDCP support. If you want one of these panels and you want to use HDCP protected content (a games console or a Blu-ray player, for example), you NEED to purchase this Auria and not one of the other versions of the panel.

    I have the Achieva Shimian that was purchased three months ago. I checked on Nvidia Settings and it states that "This display supports HDCP."

    Happy that this article was posted and I been very happy with my purchase.

    As for lag, i heard from "razetheworld" that when the monitor has one connector (usually DVI) the input lag can be as low as 6ms on these IPS screens. When there are multiple connectors like the monitor being reviewed here, higher lags are expected because the monitor takes time to process which connection is in use. I may be wrong, so correct me if i am wrong.

    There are 3 models available from an American company based in California called Overlord Computer, one of these models can be overclocked to 120 Hz. I would like to see these monitors tested. One of them is priced under $400.

    While this is true, MicroCenter has a great return policy, I'm not sure about Overlord, but I do know the one that is under 400, its 384, only has DVI, while this has HDMI, DisplayPort, DVI, headphon jack, and VGA. So if you just want DVI, getting an Achieva Shimian is cheaper off of ebay, but then also you have to deal with possible shoddy return system. Good luck to all and I will comment once I have my Auria, I'm going from my 40" Auria 1080P HDTV to a Auria 27" 1440P IPS monitor, good trade I think.

    Most video cards have Dual link DVI so this isn't really an issue unless yours does not. I use a Catleap Q270 monitor right now (let me tell you, there is NO going back for me after getting one of these, 1080p monitors are as good as yesterday's trash to me). This was a B grade panel and it ended up having no visable defects or bad pixels (I only paid $245 for it off of ebay new from Korea, they've gone up $100 since). The reason I ended up going with the panel I did was from a quite extensive post on hardforum detailing how the DVI-only monitors were having incredibly low input lag compared to any of the other 1440p IPS panels available. I'm getting incredible framerates with my 670 and my games are streak/ghost/stutter/tearing free.

    Maybe this Auria monitor just can't hack it vs. its' Korean counterparts.

    Also it's good to know you can always take apart these monitors and replace the PCB so that you can overclock them to 120Hz, but Overlord is the only place selling the part and it's $200 :(

    Minimum and maximum refer to the brightness setting. It's not unusual for the contrast ratio to go up when the brightness is lowered. In the case of the Samsung S27B970D, the black level dropped by a greater percentage than the peak white level; hence the higher contrast ratio.

    Hard choice, Replacing my current 32” Samsung LED HDTV. My choice has narrowed to the Asus 27” PB278Q (Uses the same IPS panel as the Samsung) and the Auria EQ276W. Resolution and connectivity are the same.
    Asus PB278Q: $660 w/3yr manuf warrantee
    Auria EQ276W: $400 Plus $90 for additional 2 Yr warrantee (To take it to 3 Yrs), Plus $20->$24 for tax, Plus approx. $60 for gas. Would want to see before purchase – Verify pixels and back light.
    Comments on the very fine article. The model evaluated is most likely not the model you will now find at microcenter. Apparently they have switched from a LED backlight to the traditional tube, also the screen type is now AG and not the glossy as reviewed.

    Something like this is tempting to me, but it's not a $400 purchase; it's a $400 purchase for the monitor, and another $375-$425 for a GTX670 or HD7970 to run it.

    I have this monitor and it has been great so far (about 2 months).

    For the input lag test what connection was used? I have heard Display port has lower lag then DVI but it would be great for Tom's to confirm as I trust their testing methods.

    I purchased a Qnix (South Korean via eBay brand) almost a year ago now. It does indeed have HDCP. Looks and works great. I won't go back to a TN panel, or a lower res.

    The Asus PB278Q is next up in our review queue. In fact, the benchmark tests will be run today. It will appear in a couple of weeks along with the HP ZR2740w.

    We use the HDMI input for input lag and response tests. The signal is fed from our Accupel pattern generator. We do this because input lag can vary between video cards, as well as other computer components. Even the keyboard or mouse can make a difference. The generator lets us feed a signal directly with no other hardware in the chain.

    For anyone interested in the effect of a 2560x1440 display on your 3d framerates, simply go to your nvidia driver control panel -> display scaling -> turn on GPU (as opposed to monitor) scaling -> create a custom resolution of 1440p and apply it. Text will be blurry, but your GPU workload will increase to the full 1440p and game framerates will suffer accordingly.

    You shouldn't be using HDMI for 1440p. Everyone knows that. Can we please have these tests re-run on DP and DVI-D please.

    From what I'm reading, Apart from the Asus released in Novemeber of least year, most of these 1440p monitors (like the Dell) don't support native resolutions of 1440p via HDMI.

    However, I also cannot find very much information on the subject.

    BigMack70Would have been interesting to see a basic ~$150-200 60 Hz TN panel included in the comparison charts for reference as well, since most people who would be in the market for this monitor are likely coming from a lower-end TN screen.


    Wrong, most people who would be in the market for this want a nice LG Panel IPS 2560x1440 monitor. Prices tend to come down on most computer parts, components and related items in time, and monitors have proven to be no exception.

    Most people in general would now choose something like featured monitor at $399 instead of paying $1,000 - not because they are low end TN screen users, but because it simply makes a lot more sense.
