Great colors and excellent picture quality are two of the main factors that help create immersion while you’re gaming. Despite the importance of good color, monitor manufacturers don’t always calibrate the color of their panels to what is deemed accurate within specific color spectrums – sRGB/Rec.709, etc.
We like to test each monitor for color reproduction to see how they would perform in color-accurate scenarios.
Here are the results for the AOC AGON AG254FG:
Like always, we started off the color accuracy testing portion of this review by loading up our colorimeter and running a test right out of the box. Below are the results:
Out of the box, I was incredibly impressed with just how accruate the AG254FG actually was. In past AOC monitors we’ve tested, color accuracy on their premium gaming monitors hasn’t been a priority. However, that doesn’t seem to be the case here. Colors were fantastic right from the get-go, with white point nearing a perfect score. The black depth was also impressive, coming in at under 0.1cd/m2 and gamma was set to around 2.25. Most impressive, however, was the average deltaE – a figure that is normally around 2-3 out of the box. For the AG254FG, we recorded a cool 0.61 deltaE – making this one of the most color-accurate gaming monitors we’ve tested in its default settings.
Unusually, this monitor didn’t come with an sRGB color preset. It did have the option to enable sRGB colors in the luminance tab, but they were already activated out of the box. And if truth be told, switching between the on and off settings for this particular didn’t seem to do a great deal to the picture at all.
That said, we didn’t test any of the other presets for accuracy as they were all far too vibrant or lacking in certain colors shades.
At this stage, we decided to calibrate the panel to see how accurate the monitor could be. By doing this we also get a read-out of color gamut volume and coverage for the sRGB, DCI-P3, and Adobe RGB spectrums.
For the best results, we used the following RGB values 52/50/48.
Here are the results:
As you can see from the results above, the overall accuracy of the panel was better after calibration (to be expected). But not by much. White point stayed solid at around 6500K and black depth now increased to a little over 0.11cd/m2. Contrast ratio took a small dip to 1046:1 whie average deltaE improved to 0.26, respectively. The maximum deltaE, however, was still 1.66 which meant this monitor won’t make the best editing panel – who figured?
All being said, this was still a very impressive monitor as far as general colors were conerned, ticking a lot of the right boxes.
Panel uniformity is a test we run to check how uniform the luminance and colors are across the entirety of the screen. During this test, the center square is used as the reference space. Every other square is then tested to see how far it differentiates from the reference.
In an ideal world, we want every square to be green, meaning it hasn’t broken the differential threshold – something we can set at the start of the test.
Note: results will differ from panel to panel.
Our 3 x 3 panel uniformity test didn’t see the AG254FG excel like we’d expect. Only the centre segments passed the nominal tolerance level to a decent standard. The outer segments all resulted in an amber score which, while this is a pass, is still far from ideal. That being said, this lack of performance doesn’t dint the viewing experience at all. Even when watching content with large blocks of color I found it hard to notice any artifacts.
Like all IPS panels, the AG254FG offered up extremely good viewing angles. We’ve taken a short video below so you can get a better idea of how the viewing angles look:
As part of the calibration process, the DisplayCal will give an accurate measurement of the color gamut the monitor can provide. Below are the results of the color gamut test:
Strangely, I couldn’t find any setting that met the AG254FG’s specifications as far as color gamuts go. According to the website, the monitor is able to reach 110% sRGB and 86% DCI-P3. However, as you can see from the table above, our panel only recorded 68.6% of the DCI-P3 gamut.
