Guide – Reduce Screen‑Sync Lag

How to reduce lag in RGB screen sync

If your screen‑linked lighting feels a beat behind what's happening on‑screen, walk through this checklist to improve responsiveness without sacrificing too much performance.

1. Check capture method and monitor selection

Make sure your controller is capturing the correct display (especially on multi‑monitor setups) and, where the software allows, prefer more direct capture modes over slower fallbacks.

2. Tune update rate and smoothing

Many controllers let you adjust how often LEDs update and how aggressively colours are smoothed. Higher update rates can feel more responsive but cost more CPU; heavy smoothing can make things feel delayed even when latency is technically low.

3. Avoid unnecessary background load

Close other overlays and heavy background tasks that might interfere with capture. Screen‑sync is particularly sensitive to GPU and compositing overhead, so keep other visual tools to a minimum when testing.
