Most “OLED care” tools wave at the problem — periodic screensavers, blanket dimmers, pixel shifters. OLED Guard models the actual quantity that drives panel aging and pushes back where and when the model says risk is building.
Burn-in is luminance multiplied by time on the same pixel. The engine runs that integral every frame, on the GPU, for every pixel on every connected display. Hot regions cool when content moves; static elements like HUDs and taskbars build up exposure that the protection overlay can react to.

Blanket-dimming a whole screen is what screensavers do. The engine looks at per-pixel motion every tick and lets dynamic regions through untouched, so video, gameplay, and scrolling feel exactly like they always have. Static content is what the overlay focuses on, because static content is what burns in.

Game HUDs live at the edges — health bars, minimaps, ammo counts, scoreboards. The action happens in the centre. Gaming mode shapes the protection field so the radial periphery gets the most help while a configurable inner zone stays clear. Tune the radius per game.

Frames captured by DXGI Desktop Duplication never leave the GPU. They flow into a shader that updates the exposure histogram, then into a second shader that renders the protective overlay, which DWM composites back onto your desktop using premultiplied alpha. CPU round-trips: zero.
