Windows 11 Bug Forces Dolby Vision On, Causing Washed-Out Colors and Sound Issues

Many users with OLED or HDR-capable displays on Windows 11 noticed that HDR video, especially Dolby Vision, keeps force‑activating even when disabled. This leads to washed‑out colors, sudden sound drops, or odd color tints like purple and green after restarting or waking the PC .The root of the problem ties to changes in Windows 11 update KB5058499. While this update aimed to give users more control—allowing separate toggles for HDR streaming and Dolby Vision support—it appears to trigger Dolby Vision automatically under certain setups, particularly with LG OLED TVs or high-end monitors .Affected users report that even after disabling Dolby Vision in Settings under System → Display, the option flips back on after reboot. The result is inconsistent visuals and a frustrating need to repeatedly toggle checkboxes to restore standard HDR or SDR output .A popular workaround shared on Reddit suggests toggling the Dolby Vision setting off, restarting, and repeating the process several times. That sometimes works temporarily, but isn’t a reliable fix. Other users have turned to external tools or monitor firmware updates to disable Dolby Vision entirely .Microsoft introduced the new HDR controls to let users selectively enable HDR streaming without forcing HDR system-wide. Now they also offer an on/off switch for Dolby Vision. But this flexibility hasn’t resolved the recurring bug — Dolby Vision is still auto‑reverting for some users .Experts advise checking your monitor or TV firmware for updates, as some include options to fully disable Dolby Vision at the source. In the meantime, users can manually toggle the setting or use third-party tools to disable the feature until Microsoft rolls out a fix.If this issue is affecting your viewing experience, keep an eye out for an upcoming Windows update that addresses HDR and Dolby Vision reliability.
