DyAc+ locks a tighter pulse width around 190µs, but I keep catching faint double-edge ghosting on fast sweeping crosshairs that smells like residual afterglow rather than panel holdover. For anyone who’s measured this with a photodiode: what residual persistence window are you actually seeing from DyAc+ versus ULMB 2’s dual-backlight strobe, and is that second-frame ghosting I’m chasing a known artifact of the dual strobe architecture or something in my signal chain? The ULMB 2 dual-backlight engine is clearly designed to push brightness past the single-strobe limit, but the flicker-efficiency tradeoff is eating my usable nits.
