Frequently Asked Questions

OLED burn-in happens when static content (taskbars, HUDs, logos) stays on screen for extended periods. The organic compounds in OLED pixels degrade unevenly, leaving faint ghost images permanently visible. It's caused by bright, persistent, unchanging content — not simply by using the display.

OLED Guard Pro captures your screen in real-time using DXGI Desktop Duplication, analyzes per-pixel brightness and persistence on the GPU, and renders a protective overlay only where burn-in risk is detected. It tracks actual exposure accumulation — the same physics that cause real burn-in — and responds proportionally.

The Free version includes basic single-monitor protection with limited presets. Pro adds multi-monitor support, all protection modes, app profiles, automatic mode, DDC/CI brightness control, gaming mode, and advanced settings.

Yes. OLED Guard Pro uses the same per-pixel exposure model that describes how real OLED burn-in occurs. By tracking where risk is building and intervening early, it prevents the uneven pixel degradation that causes permanent ghosting.

Windows 10 (version 1903 or later) or Windows 11, any DirectX 11 compatible GPU, and about 50 MB of RAM. The app is lightweight — all heavy processing happens on the GPU.

Both versions are identical in features. The Steam version integrates with your Steam library and overlay. The Microsoft Store version supports the Free tier. Choose whichever store you prefer.

This is normal for newer applications. Click "More info" then "Run anyway". This prompt only appears once.

Start with Automatic Mode — it adjusts all parameters in real-time based on what's actually on screen. If you want manual control, Noise mode is the most effective for general use. Gaming mode adds edge-weighted protection for game HUDs.

At low intensities, the noise overlay is nearly invisible. You might notice it on solid-color backgrounds if you look closely. The overlay becomes more visible as burn-in risk increases, which is intentional — it's protecting the areas that need it most.

OLED Guard Pro is most effective against static content burn-in (taskbars, HUDs, logos). It cannot reverse existing burn-in damage, but it can slow further degradation and prevent new burn-in from forming.

Yes — OLED Guard Pro works in borderless fullscreen games, which is the recommended mode. In exclusive fullscreen, the app pauses rendering and resumes when you alt-tab or exit the game.

No measurable impact. Screen capture uses hardware-accelerated DXGI Desktop Duplication (near-zero cost), and all processing runs in GPU shaders. On a modern GPU, expect less than 1% overhead even at the highest quality preset.

Select the Gaming preset from the Protection page, or enable edge weighting manually. Gaming Mode applies stronger protection at screen edges (where HUDs are) and delays protection in the center (where gameplay happens).

Yes. OLED Guard Pro works with any OLED display connected to a Windows PC — including OLED monitors, OLED TVs used as monitors, and OLED laptops. It doesn't need to know the specific panel model.

Fully supported. Each monitor gets its own independent capture pipeline, render pipeline, and settings. You can enable protection on your OLED displays and leave it off on any LCD monitors.

Yes. The overlay composites through the Desktop Window Manager using premultiplied alpha, which works correctly in both SDR and HDR modes.
