: Flicker is most noticeable in darker scenes or shadows . This is because the gamma shift is more pronounced at low luminance levels where the voltage control is most delicate.

The primary reason for flicker on OLED panels is the relationship between the .

: When VRR is active and frame rates fluctuate, the time each pixel is "held" in a lit state changes. Because OLEDs lack a traditional backlight and regulate brightness at the pixel level through voltage, these timing changes cause minute shifts in perceived brightness.

: OLED pixels are extremely sensitive to voltage. Manufacturers typically optimize a panel's gamma curve for its native (maximum) refresh rate.

: Unlike LCD backlight flicker (often caused by PWM dimming), OLED VRR flicker occurs at the electrical level when the panel attempts to modulate voltage in real-time to match varying frame times. Common Symptoms and Scenarios VRR Flicker On OLEDs Is A Real Problem : r/hardware
