There are reports about the green tint or shift being a widely recognized phenomenon with LG WOLED panels, including the LG 65" Class C5 Series OLED evo AI 4K UHD Smart webOS TV (2025), Model # OLED65C5PUA, or LG C5 series, and while your HD/UHD streaming content itself isn't the root cause, low bitrates and over-aggressive AI picture processing on streaming platforms can heavily exaggerate the issue. Slight color shifts, especially visible on off-angles or near-white/gray backgrounds, are inherent to the WOLED technology. Some users note that the anti-reflection coating on LG C-series panels can cast a slight green hue depending on the ambient lighting and viewing angle. Compressed HD/UHD streaming can result in "color banding" or "mosquito noise" in dark scenes. The TV's processor tries to smooth these gradients out, which can inadvertently create visible greenish patches in shadows or grayscale areas. LG's out-of-the-box settings are often tuned slightly warm, which mixes with the panel's native white point and can make flesh tones and dark grays look sickly or green. If faces look green, you can try adjusting the color temperature to a warmer setting or use the TV's 2-point white balance. Setting it to Warm 50 generally produces the most accurate image. Use FILMMAKER MODE or ISF Expert (Dark/Bright Room). These modes disable many of the dynamic AI enhancements that can distort skin tones and over-saturate color gradients. In your settings, navigate to Picture > Advanced Settings > Color > Tint, where you can slightly adjust the slider toward red to counteract a strong green cast. If the tint appears as a static blob or vertical banding in the center of the screen, it could be image retention or pixel aging. Run the Pixel Cleaning (or Pixel Refresher) cycle via the TV's OLED Care menu and let it complete. In the streaming apps or the TV's AI Service menu, experiment with turning off AI Picture Pro or AI Brightness. These settings sometimes apply localized contrast boosts that mess with color fidelity on low-bitrate streams. If the green tint is visible from straight on and across all bright scenes, not just compressed streaming content, you may need to schedule a repair service appointment...^Ivan.
