Ghosting occurs when liquid crystals in LCD panels take longer to transition between gray states (GtG response time) than the frame refresh period, leaving visible trailing smears behind moving objects.

Inverse ghosting occurs when monitor pixel overdrive voltage is set too aggressively, causing liquid crystals to overshoot target gray levels and creating bright trailing halos (coronas).

Ghosting Invaders moves target reticles across dark-gray and light-gray background channels at configurable speeds (960 px/s to 3840 px/s), allowing visual comparison of trailing artifacts.

GtG measures how fast pixels switch colors; MPRT measures how long a pixel remains visible on screen during a frame, governing sample-and-hold motion blur.

OLED self-emissive sub-pixels switch states almost instantaneously (<0.1ms GtG), eliminating liquid crystal rise/fall delays and smearing.

Select a 'Medium' or 'Fast' overdrive profile that minimizes trailing blur without introducing bright white/cyan inverse ghosting coronas.

Without variable overdrive tuning, lower FPS under VRR causes liquid crystals to overshoot target brightness levels, producing increased inverse ghosting.

BFI strobes the monitor backlight off during pixel state transitions, clearing human eye retinal persistence blur for CRT-like motion clarity.

VA liquid crystals have extremely slow response times when transitioning from pure black (0% luminance) to dark gray (5-10% luminance), causing dark smearing.
