@4krender: Fix your OLED HDR screen To fix image retention, stuck pixels, or mild burn-in using a flashing static or color-cycling video like this, display it full screen at full brightness for 30 to 60 minutes uninterrupted. The rapid, high-contrast flashing forces subpixels to continually switch states, helping to unstick frozen pixels and even out localized pixel degradation. If the lines or distortion persist after extended playback, it indicates physical hardware damage to the OLED display driver or panel, which cannot be cured with video cycles and requires professional screen replacement.#flashwarning #hdr #dolby #oled #
