Only global strobing. Not rolling-scan hardware strobing. (i.e. rolling-scan OLEDs)
Rolling-scan strobe can be be lagless.

You can strobe in sync with the LCD scanout. (It helps to understand the WHY strobing add lag -- see high speed videos of http://www.blurbusters.com/scanout ....). Global-flash strobing has lag because the LCD scanouts in the dark and then there's a global flash at the end.

Learning about all this has got me interested in learning even more about LCD hardware and electronics in general. Any suggested resources for a total n00b? I think I may ultimately have to rig up a custom LCD, or pay someone to do it.

There an old FAQ at http://www.blurbusters.com/faq/creating ... -backlight .... Though if you mod an existing strobe backlight (for brighter strobing), the modification considerations are different (amplifying brightness via LED overvoltaging or LED replacement), more fully backlight modification and probably no firmware modification.

Modders are few and far between for displays because of the high-cost and difficulty, but a few people like Zis at http://www.zisworks.com do things similar to this.
