This hidden beta screen simulates an LCD by simulating slower pixel response (Gray-to-Gray transitions) including exponential GtG curves, overdrive overshoot, sample-and-hold persistence, and LCD motion blur reduction modes (including accurate strobe crosstalk simulation).

LCD motion blur comes from two sources: sample-and-hold (pixel stays lit between refreshes) and GtG response time (pixel takes time to transition between colors). For more information, see GtG versus MPRT on Blur Busters.

2. Simulate Circa 2002: Old Color LCD (33ms GtG)

3. Simulate Inverse Ghosting: too much overdrive on a 60 Hz LCD

4. Super Slo-Motion: Watch LCD GtG pixel transitions in action

The GtG model is an improved variant of the dual-exponential approach used in Blurinator 9000 by Marián Vlček and various formulas that mathematically modelled LCD GtG pixel response, as well inspired by an old pre-TestUFO application called PixPerAn.

Backlight Modes: Steady (normal LCD), Blur Reduction Strobe (like ULMB/DyAc/etc), or PWM Dimming (requires 6:1 native:simulated ratio).
Real-Time Simulation Recommendation: Use native:simulated Hz ratio of 2:1 (120 Hz for Steady), or 4:1 (240+ Hz for Strobed), or 6:1 (360+ Hz to simulate PWM dimming).
Photosensitivity Notice: Strobe/PWM modes contain flicker
