Uncalibrated – Maximum Backlight Level
In the peak SDR brightness test, the monitors are separated into those with variable brightness and those without. The S27FG60 falls into the latter category with 322 nits available. I tried the Contrast Enhancer and found it did not affect the peak level. I measured the same numbers from both full-field and window patterns. This is not a slight, though. 322 nits is more than enough light for any office or media room environment. Black levels and contrast cannot be measured.
After Calibration to 200 nits
If you drop the brightness slider to 200 nits, there is no change other than in peak output. Contrast and black levels remain below the measurable threshold. The same holds true in the ANSI test where I cannot measure the black squares in a checkerboard pattern. This is typical OLED performance.
Test Takeaway: The S27FG60 doesn’t have variable brightness for SDR content so it peaks at a modest but more than sufficient 322 nits. If you need more than 500 nits, Asus and Aorus can accommodate. But in the end, there is no difference in contrast between the S27FG60 and any other OLED. Blacks are truly black, and the picture is stunning.
