Yes, it does.
(Why do you ask such an obvious question similar to “What color is the sky?”)
This is true regardless of strobe backlight, so I’m very curious why you ask a question – every strobe backlights ever invented has less motion blur than without strobing, when used correctly at framerate=Hz.
But you specifically asked versus non-strobed, which ends up to my brain as if you had never seen backlight strobing based motion blur reduction algorithms before – So if you actually have experience, maybe you need to rephrase the question so I can answer your question better, if you maybe meant “strobe crosstalk” instead of “motion blur”? Just want to be clear so I can correctly answer your question – thanks!
Terminologically, are you taking about some other attribute such as strobe crosstalk, or some other artifact, but might have used the wrong terminology such as “ghosting” vs “coronas” vs “persistence blur” vs “strobe crosstalk” which are all 4 different things.)
But the answer, is yes to all 4, at least in the territory of KSF panels.
Versus other KSF panels
Ghosting = the least ghosting I’ve ever seen on KSF panel
Corona = the least corona I’ve ever seen on KSF panel
Persistence blur = the least persistence blur I’ve ever seen on KSF panel
Crosstalk = the least crosstalk I’ve ever seen on a KSF panel
Ghosting = much less ghosting than non strobed
Corona = much less corona than non strobed
Persistence blur = All strobe backlights in humankind reduce this
Crosstalk = This is the biggie because non-strobed has no crosstalk, and strobed always has crosstalk (even if it’s only 3% or 1.5% or 1%), so crosstalk is always a downgrade for strobe backlights on all strobed LCDs ever invented in humankind. That is where Blur Busters tuning works very hard to reduce as much as possible, so that crosstalk is not as noticeable.
Fortunately, crosstalk is near zero for screen center, leaving only faint KSF ghost that is hard to see. Now, the amount of crosstalk for top/edge depends on how much refreshrate headroom you choose, and how much vertical totals you decide to do concurrently with refreshrate headroom.
Now, Bigger VT = Bigger VBI = more time for LCD GtG pixel response in total darkness between strobe flashes, like High Speed Video of Strobe Backlight | Blur Busters (old 2014 video)
Reminder: crosstalk double-image is not motion blur
Now, plasmas and CRTs use phosphor that has visible ghosting, while nearly all LCD has no phosphor ghosting at all. It’s only a very few LCDs that have phoshphor-derived ghosting, such as KSF (chemical K2SiF6 doped with Mn4) in the backlight LEDs of a NanoIPS panel, typically manufactured by LG. That’s why I compare to plasmas and CRTs, because many people interested in backlight strobing are of people who’ve seen CRTs or plasmas in the past. So I mention them as a point of reference. :Your question is sometimes asked by younger millenials – maybe should have prefaced “If you have ever seen a CRT tube and a plasma display while computer gaming…”) in order to ground a person with a reference point whereupon to scientifically compare motion blur to. (most younger millenials have not spent significant time playing games on CRTs for example – they were superlative for zero motion blur but they still had a minor amount of green-colored phosphor ghosting for bright objects on black background. Plasmas have yellow-colored phosphor ghosting, while KSF LCDs have red-colored phosphor ghosting for strobe operation)
Certainly not as zero-crosstalk-perfect as say, the Oculus Quest 2 VR LCD, or perhaps, say the Blur Busters Approved 2.0 Certified monitors (but then again none are 4K yet, and currently none are wide-gamut yet).

This will help you get familiar with the correct terminology for the various different LCD motion artifacts (blur, crosstalk, coronas, ghosting). Be noted, 2,3,4 of them can occur simultaneously (e.g. a crosstalk double image that’s simultaneously a negative-image corona, or a crosstalk hybrid between persistence blur and ghosting (like KSF). Perhaps if you would like to describe the specific artifact you would like less of, I can help give perspective.
Now, if you’re wondering about the artifact in the early YouTube video of the old firmware – that’s strobe crosstalk, not motion blur. I instantly recognize the crosstalk (majority of it is not the cause of KSF), it’s from approximately firmware 100R800 through 100R848 – about exactly the same intensity. But of a sudden, firmware V100R852 and newer, has approximately 1/10th as much strobe crosstalk. Big improvement jump there. Some reviewer needs to properly test that.
Anyway, that’s why I reminded Eve to make sure to install the latest firmware thereafter, to any units sent to reviewers, if they want to review the Tuned by Blur Busters strobe.
Now, if this is all new to you, strobe crosstalk is caused by LCD GtG being unfinished in the interval between refresh cycles. LCD is getting faster and it’s becoming easier to cram the GtG elephant in the drinking straw of the gaps (VBI) between refresh cycles. But KSF does throw a monkey wrench into this ability.
These are artifical PhotoShopped examples of crosstalk photography, to mathematically show incompleteness of LCD GtG pixel response cascading into a strobe crosstalk artifact.
- If GtG only finishes 75% in dark period between refresh cycles, you get 25% crosstalk.
- If GtG only finishes 90% in dark period between refresh cycles, you get 10% crosstalk.
- If GtG only finishes 97% in dark period between refresh cycles, you get 3% crosstalk.
- If GtG only finishes 99% in dark period between refresh cycles, you get 1% crosstalk.
LCD GtG pixel response (GtG = grey to grey) is a pixel slowly fading from an old color to a new color. For each of the pixels on the display. If you are unfamiliar with GtG, please read GtG versus MPRT: Frequently Asked Questions About Pixel Response On Displays | Blur Busters
Also, not all pixels refresh at the same time on any LCD ever invented, see Understanding Display Scan-Out Lag With High Speed Video | Blur Busters …
So the problem causing strobe crosstalk double images is caused by laws of physics – you’ve got 2 lags going on (scanout lag and GtG pixel response lag) so you have to hide both of these lags in an unusually long blanking intervals to reduce the crosstalk at the screen top edge and screen bottom edge.
There’s more crosstalk at top/bottom edge because there’s less time of the backlight being turned off since the pixel started its GtG pixel transition (the “crosstalk band” is an interference band caused by law of physics, of the sequentialness of LCD refresh, and the globalness of whole-backlight flash). This affects all LCDs.
Fortunately, I also provide an adjustable strobe phase, so you can move the band almost offscreen. And if you use a lower Hz with a larger VBI (e.g. 60Hz QFT large VT mode), you can have top/center/bottom almost identically clear on the Spectrum. That’s since a faster scanout (e.g. 60Hz refresh cycle sweep-refreshed top-to-bottom in a mere 1/144sec) makes the LCD more closely resemble a global-refresh display than a sequential-refresh display.
Now, I realize this is educational STEM stuff (science, technology, engineering, math), but hopefully this helps explain the cause of strobe crosstalk better, assuming that is what you are referring to (instead of “motion blur”).
So, it’s possible that an old firmware can have 25% crosstalk, and an upgrade of firmware can reduce that to 3% or 5% crosstalk. This is the magnitude of improvement between V100R848-and-older, as well as V100R852-and-newer, so I was a bit disappointed the dominoes didn’t finish falling completely yet (myself, my staff, Suzhou Lehui, their staff, the factory, and then finally Eve to ship – it’s a dominoes from the development desk to the mass production assembly line and shipment company). But reviewers can now firmware upgrade, so that’s the great thing. It is what it is – and at least any newer monitors sent to reviewers nowadays, now already has the latest firmwares.
