Many OLEDs like the FO32U2P come with factory calibrations. This is appropriate given their premium status and high price tags.
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 FO32U2P gets off to a good start with visually perfect grayscale tracking. No steps exceed 2dE, which is as good as the very best professional screens I’ve tested. It has some weaknesses in the gamma department, though. The values increase over reference as brightness increases. This means highlight areas will be too bright and some detail will be less sharp. I didn’t observe any crushing in actual content, but the picture was slightly less impactful than the Alienware AW3225QF I compared it to.
For ego’s sake, I calibrated the FO32U2P to a very high standard but could not fix the gamma errors. A compromise is possible by selecting the 2.4 gamma preset. This improves clarity in brighter parts of the image, but then some shadow detail is less crisp.
The sRGB picture mode has equally accurate grayscale and similar gamma behavior. It is a bit light across the board, with a dip at 90%, like the result I recorded for Standard and Custom modes. This mode is fine for color-critical work, but gamma tracking has some room for improvement.
Comparisons
The FO32U2P’s grayscale tracking is among the best I’ve measured. With 1.44dE out of the box and 0.43dE after calibration, it doesn’t get much better. However, gamma has room for improvement. The 0.35 range of values and 4.09% deviation (actual value 2.11) put it in last place among these premium displays. While the picture is well in the realm of excellence, the other OLEDs are just a hair better.
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.
Is there a good side to light gamma? In the FO32U2P’s case, yes. Color gamut tracking shows evenly applied over-saturation throughout. That’s a good thing because it makes the image very colorful without obscuring detail. Reds are particularly vivid while green is just a tad over and blue is spot on. The hue error in magenta is easily fixed with grayscale calibration, though the change from 2.40dE to 2.03dE is nearly invisible. No one will complain about color accuracy, saturation or quality when using the FO32U2P.
The sRGB is right on point as well. There are no calibration options in this mode, only brightness can be adjusted. But it’s completely on the mark and qualified for professional applications.
Comparisons
It’s clear that buying a premium OLED monitor means solid color accuracy, with or without calibration. The FO32U2P’s 2.03dE gamut score is superb, even though it’s a fifth-place finish. All the monitors here are top-of-the-line.
The QD layer takes DCI-P3 coverage past 107%, which is excellent, but the Alienware OLED and the two IPS screens have more color. The X32 is the current gamut volume record holder in my test database of 385 monitors. Can you see this difference? Barely. No one using an FO32U2P will complain about a lack of color. It is extremely vivid. And it is completely qualified for critical applications in the DCI-P3 and sRGB color spaces.
Test Takeaway: While a few monitors have a little more color volume than the FO32U2P, it is right in the running as one of the most colorful screens I’ve tested. Quantum Dots are where it’s at, and Aorus delivers both accuracy and saturation in generous amounts.
