Uncalibrated – Maximum Backlight Level
The AG346UCD has no real weaknesses except for brightness. And how that’s perceived is up to the individual user. Though it peaks at 236 nits, you still get the infinite blacks all OLEDs are known for. Contrast is infinite,l and don’t forget that enormous color gamut. Since there’s no option for variable brightness, the AG346UCD operates like all the other screens would if their variable brightness were turned off. Measuring a full field versus a 25% window made no difference.
After Calibration to 200 nits
Adjusting the brightness to a peak of 200 nits does not affect black levels or contrast. If you set all the monitors for constant brightness, they would look the same except for their color saturation, which we’ll discuss on the next page. The ANSI checkerboard, which measures intra-image contrast, also looks the same on all six panels.
Test Takeaway: With the AG346UCD’s brightness remaining constant for all content, its peak is at 236 nits which is less bright than a monitor with variable brightness. In practice, this manifests as less impactful highlights. Variable brightness gives a panel more pop and verve. The AG346UCD has great color though and that may appeal more to some users than peak luminance.
