OLED Guard — Screen Dimmer, True Black & Pixel Shift for OLED/AMOLED

Your OLED laptop or monitor cost between $1,200 and $3,000, and burn-in is excluded from most panel warranties. The hardest thing you can ask that panel to display is a web browser: the same nav bar, the same sidebar, the same bright logo, at the same pixels, at the same brightness, eight hours a day. OLED Guard reduces the static-pixel exposure your browser puts on that panel — and then shows you the numbers, so you can check the work instead of trusting a claim. It runs entirely on your machine. No account, no subscription, no analytics, and no network requests at all except to the payment processor if you decide to upgrade. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES NOT DO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Read this part first. It's the part most extensions leave out. • It does not prevent, cure, or reverse burn-in. No browser extension can, and any that says otherwise is selling you something. • It cannot reach your tab strip, address bar, bookmarks bar, taskbar, dock, or any other application. A browser extension only reaches the page content area. That is a real limit and it stays a real limit. • It does not replace the compensation cycles your display already runs in firmware. Those keep running. This works on top of them. • It is not a force-dark extension. If what you want is every website inverted, use Dark Reader — it does that better and it's free. OLED Guard runs alongside it without conflict. What it does do: reduce the cumulative static-luminance load inside the browser content area, which is where most people spend most of their screen hours. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO THIS IS FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Anyone working all day in a browser on an OLED or AMOLED laptop screen • QD-OLED and WOLED monitor owners — the 27" and 34" ultrawide panels people code, design, and trade on • Anyone using an AMOLED tablet or portable display as a second screen • Developers and designers who leave the same IDE, dashboard, terminal, or documentation page open for hours without scrolling • Anyone on any kind of display who simply wants a genuinely dark browser and less glare at night — see comfort mode below ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FREE — no account, no trial timer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ GLOBAL DIM A true black overlay from 0 to 45%, on a live slider. The popup dims itself as you drag, so you preview the effect on the control you're holding. The slider track is a luminance ramp running from pure black to the page's own average colour. ▸ PER-SITE MODES Auto, Off, or a custom dim level per website. Set it once for the sites you leave open all day; every site you visit afterwards follows your global default. ▸ TRUE BLACK On sites that are already dark, the base canvas is forced to #000000 so those pixels are physically off — not dark grey, off. Elevated surfaces like cards, menus, modals, and code backgrounds are detected and left intact, so the interface keeps its depth instead of collapsing into a flat black sheet. On a self-emissive panel, an off pixel draws no power and emits no light, which is where the contrast and the battery savings both come from. ▸ IDLE FADE Sixty seconds without input and the page fades further, over twenty seconds so you never catch it moving. Lock the machine and it goes to full immediately. One keystroke or mouse move brings it back in a quarter of a second. Automatically suspended while video or audio is playing. ▸ COMPARE Hold one button in the popup, or press Alt+Shift+P, to flip instantly between on and off. This is the entire pitch in a single gesture: if you can't see a difference on your own screen, don't buy the paid tier. ▸ SHOW STATIC REGIONS A ten-second diagnostic overlay that outlines every element which has been sitting still on the page, with how long it's been there. Dashed outlines for fixed and sticky elements, solid for in-flow. Free to look at on any site. ▸ AUTOMATIC EXEMPTIONS Fullscreen video, playing in-viewport video, and colour-critical work are left completely alone. Browser-based design, photo, and colour-picking tools are excluded by default, as is any page with a colour picker open. Nothing is dimmed while you're judging colour or watching a film. ▸ KEYBOARD CONTROL Alt+Shift+O toggles everything. Alt+Shift+P is Compare. Both rebindable from Chrome's shortcuts page. ▸ HONEST BADGE The toolbar badge always shows the live dim percentage, in green when active and a grey dash when off. You never have to open the popup to know what state you're in. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRO — $29.99, one time, forever ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Not a subscription. There is no monthly plan, no annual plan, and no upsell after purchase. ▸ PIXEL SHIFT The entire page steps by one pixel at a time through a sixteen-point lattice, cycling roughly every ninety seconds. It's the same principle as the pixel-shift feature built into modern televisions, applied to browser content: nothing sits at exactly the same coordinates indefinitely. Steps are timed to fire underneath your scroll events, so the movement is hidden inside motion you already caused. Fixed headers, sidebars, and floating buttons are detected and shifted individually so nothing tears away from the layout. On sites where the measurement gets expensive, it automatically degrades to shifting only the fixed elements rather than slowing your page down — and tells you it did, per site. ▸ STATIC-REGION DIMMING Elements that have genuinely held still — over three minutes, and bright — get dimmed individually. The ramp down takes three seconds and the restore takes four hundred milliseconds, and that asymmetry is the whole trick: it fades away slowly enough that you don't notice, and comes back the instant you look at it. ▸ LOGO AND WORDMARK DECAY Small, bright, saturated fixed marks — the exact shape of the classic burn-in complaint — get their own longer threshold and a deeper dim floor. ▸ EXPOSURE DASHBOARD A per-sit…
