HDR Switch for RTX Video

Turn NVIDIA RTX Video HDR on or off per video: shortcuts, auto-detect white videos, NVIDIA presets, SDR sync and eye care.

HDR Switch for RTX Video lets you turn off NVIDIA RTX Video HDR one video at a time. Lecture slides, screen recordings, and late-night viewing drop back to comfortable SDR, while your movies keep their full HDR punch. Per-video HDR switch Press Alt+H to turn RTX Video HDR off or back on for the video you are watching. The change applies instantly in both windowed and fullscreen modes without reloading the page, and the extension remembers your choice for each individual video.

Hover over the button to open a control panel for the current video, current site, white-screen detection, NVIDIA settings, and profiles, including in fullscreen. Press and hold the button to compare HDR and SDR on the fly until you let go. HDR only in fullscreen Keep windowed playback in SDR and automatically switch to HDR when entering fullscreen, either as your global default or for individual sites. White-screen detection The extension samples the video frame every 1.5 seconds and switches playback to SDR after 3 seconds of bright white content. Press Alt+Shift+H to turn auto mode on or off at any time. Keep for this tab When you switch two videos in a row the same way, the on-video label offers to keep that choice for upcoming videos in the current tab, covering autoplay queues, playlists, and multi-part videos. Status at a glance The toolbar badge clearly displays HDR, SDR, or DRM for the active video in your current tab. Site rules, night mode and viewing reminders Configure custom rules per site, schedule automatic SDR playback during night hours, and receive a timely reminder to rest your eyes after a long HDR viewing session. Profiles Save your general rules, site rules, and NVIDIA settings under a custom profile name. Switch profiles effortlessly from the popup, the player panel, or a keyboard shortcut, with the option to undo any switch within 10 minutes. Copy any profile as plain text to transfer and use it on another PC. NVIDIA controls (local helper) Turn RTX Video HDR on or off globally and fine-tune peak brightness, middle grey, contrast, saturation, Super Resolution mode, GPU priority, and NVIDIA's on-video status indicator. Save custom presets, switch them automatically by time of day, or bind a specific preset to any site. Every change the extension makes is logged with its source and can be undone. Match Windows SDR brightness (local helper) Read your display's SDR content brightness and sync middle grey, peak brightness, and contrast in a single click, or let middle grey automatically follow the Windows SDR brightness slider. Press Alt+Shift+Up and Alt+Shift+Down to nudge middle grey up or down by 5. Turn off HDR only, keep super resolution (local helper) When the active video is set to play in SDR, this mode switches NVIDIA's global HDR off behind the scenes so Super Resolution continues enhancing the image. Global HDR automatically turns back on afterward, including when the browser closes or crashes. Themes, backup and diagnostics Use the popup interface in English or Chinese, personalize the appearance with six built-in theme colors or a custom shade, and easily export or import your settings, presets, profiles, site rules, and remembered videos. A built-in diagnostics page displays the local helper's status along with clear solutions for common issues. Local helper The NVIDIA tab works with a lightweight local helper for Windows.
