The flicker becomes more bothersome the lower the 'Brightness' setting, because the PWM duty cycle decreases at maximum 'Brightness' the flicker should be almost undetectable. The flicker also makes motion a little less clear as it causes the trail behind moving object to look like noticeable duplications instead of a smooth fade.
The flicker frequency is fairly high at 433 Hz, which shouldn't be noticeable to most people but may still be bothersome to those sensitive to flicker. The Samsung CHG90 dims its backlight using only PWM flicker, which is not as good as a flicker free monitor. This is provided for reference only and should not be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.

You can download our ICC profile calibration here. A small dip is still visible in the higher IRE (brighter), but this does not cause any issues overall.Īs for the color temperature, we are still a bit on the warm side, as seen on the CIE colors space map, where the white point tends toward the red-yellow, but we are really not far from our 6500K and within our noticeable difference on 400K. Looking at the gamma value and curve, we can see that the curve does track more closely our target curve, and for the gamma value, we are now a bit closer to our 2.2. The 'Gamma' mode was also kept on the 'Mode2'.
The calibration was done on the same picture mode that the pre-calibration was done, the 'Custom' picture mode, but the 'Color Tone' was changed for the 'Custom' one since we needed to adjust the RGB balance. Both the white balance and color dE were cut by more than half, and are now hovering just above the 1.0 mark, which is almost perfect for most people, even professional. After calibration, the accuracy of the Samsung CHG90 is excellent.
