That's true too -- to an extent.
Albiet, I've found that more of the effect is from the top-to-bottom scan -- something is almost always illuminated somewhere on the screen surface -- rather than flashed-all-at-once like a strobe backlight.

I have an AMD Radeon graphics adapter and the ULMB is greyed out in the monitor menu (I tried all the refresh rates, including the officially supported 85, 100 and 120 Hz).
What a bummer! Is there anything I can do about this?
Purchase an NVIDIA card.
There's no way to enable ULMB on an AMD product, unfortunately.
It requires a special DRM handshake with an NVIDIA graphics card before it lets itself activate.
ToastyX discovered a way to crack the LightBoost handshake, so it was possible to enable LightBoost on certain monitors using an AMD card. But nobody has ever done the same to ULMB, they have probably made it much stronger DRM.

I don't know whether enabling ULMB would improve things much, but it doesn't seem likely. Currently I've got severe ghosting and blur on any refresh rate. I'm inclined to return the display immediately, but... what else could I try?
ULMB is pretty good, and 60Hz ULMB does look good on a 240Hz GSYNC monitor, but if you're looking for an AMD compatible solution of successful 60Hz single-strobe that doesn't use software-based BFI -- your only choice are the BenQ/Zowie monitors.
Or getting an HDTV that single-strobes at 60Hz (RTINGS.com television reviews includes a checkbox whether that particular HDTV can single-strobe at 60Hz).
