Not necessarily. You simply need framerate == refreshrate == stroberate
for the magic point of maximized motion clarity. Same reason why CRT 60fps @ 60Hz has had less motion blur than old-fashioned non-strobe LCD 120fps@120Hz.
Strobe backights ARE
now available at lower strobe rates.
100Hz LightBoost strobing -> Use 100fps
120Hz LightBoost strobing -> Use 120fps
85Hz ULMB strobing -> Use 85fps
100Hz ULMB strobing -> Use 100fps
120Hz ULMB strobing -> Use 120fps
75Hz BENQ Z-series Blur Reduction strobing -> Use 75fps
96Hz BENQ Z-series Blur Reduction strobing -> Use 96Hz
144Hz BENQ Z-series Blur Reduction strobing -> Use 144Hz
(Note: Need XL2720Z firmware upgrade BENQ strobing bugs; recently reported on Blur Busters Forums).
Panning motion tests (e.g. www.testufo.com/photo
) automatically run at framerate==refreshrate, so they always look amazingly crisp and sharp on a CRT and on strobe backlights. You do not require 120 frames per second, it's only simply because of a LightBoost vendor limitation (like a fixed frequency CRT that only runs at 120Hz and not 60Hz). New strobe backlights have more flexible refresh rates.
That said, lower strobe rates are more flickery, though. You adjust the refresh rate for a compromise setting. Low enough to be easy on the GPU, high enough to avoid flicker/lag. If you don't have a Titan, then the sweet spot is often around 85Hz, as has often been found in the old CRT days.
In situations that frequently drop below the refresh rate minimums of a specific strobe backlight, G-SYNC is vastly superior. It provides greatly superior experience during the low frame rates, eliminating stutters and tearing so well in advanced games such as Crysis 3 -- as stutterfree 45fps often looks better than very-stuttery/teary 75fps. However, you do have to live with the motion blur, which sometimes bothers me quite a bit.
I also think that variable-rate strobing, that gradually disables itself as the framerate falls below rates below flicker fusion thresholds, would be a very reasonable solution to the variable-rate strobing problem.Edited by mdrejhon - 1/15/14 at 2:07pm
