The FO27Q2 is calibrated at the factory if you switch from the default Eco mode to Standard. It is so precise that I could not make an improvement even though RGB sliders and gamma presets are provided. It doesn’t get much better than that.
Grayscale and Gamma Tracking
Our grayscale and gamma tests use Calman calibration software from Portrait Displays. We describe our grayscale and gamma tests in detail here.
The FO27Q2’s default measurement runs yields a nearly perfect chart. Grayscale errors are all less than 1dE, which is well under the visible level of 3dE. Gamma rides close to the 2.2 line with a slight rise at 10% and a dip at 90%. These errors are nearly impossible to spot in actual content.
The sRGB mode has visibly perfect grayscale but introduces a couple of gamma anomalies. The 10% step is too light, making some shadow detail less dramatic. The 80% and 90% steps are very light, bumping up highlights and muddying detail slightly.
Comparisons
With the 0.56dE grayscale error, the FO27Q2 wins the out-of-box comparison and slips only to third place when all the screens are calibrated. And it’s only out of first by a hair. Visually, there is no difference between any of the six monitors.
In the gamma test, the FO27Q2 comes closest to the 2.2 reference with a 2.19 result, 0.45% off the mark. The range of values is a little wider thanks to the anomalies I noted in the charts above. Even though it comes last, 0.21 is very tight. The other monitors are just a little better in this test.
Color Gamut Accuracy
Our color gamut and volume testing use Portrait Displays’ Calman software. For details on our color gamut testing and volume calculations, click here.
The FO27Q2 has exemplary color accuracy even though its native gamut is a little larger than DCI-P3. Red and green are a bit oversaturated but in a way that is visually appealing. It just looks like a very colorful monitor that no user will complain about. You can dial it back with the DisplayP3 option in the OSD. Or, if you need sRGB, select that picture mode for a perfect result. 0.60dE is one of the lowest gamut test scores I’ve ever recorded.
Comparisons
The OLED monitors I’ve reviewed have been consistently color accurate and the FO27Q2 is no exception. Though it sits in fifth with a 1.91dE score, that’s only because the other screens are so good. Visually there is no difference. You’ll need to see numbers above 3dE to detect errors in content.
Quantum Dot OLEDs push the envelope for color volume and the FO27Q2 goes just a tad further than the rest with a 110.53% score. It and the AOC are QD panels while the rest are not. It bodes well for OLED tech in that it can approach 100% without help. But that extra punch is worth paying for. You can see it plainly in a comparison. You can also see full coverage of sRGB plus a little bonus red. It’s not enough to disqualify the FO27Q2 as a pro screen. This is excellent performance.
Test Takeaway: The FO27Q2 is one of the most colorful and most color accurate monitors I’ve ever tested of any type. It stands out amongst other OLEDs and doesn’t cost any more than the competition. I would pick it for myself based on the color tests alone.
