Short technical answer: Strobing (DyAc, etc) at a monitor's maximum Hz will be full of strobe crosstalk. For greatly reduced crosstalk with DyAc or any strobe backlight, you need more headroom between refresh cycles to hide pixel transitions (LCD GtG) in the dark while the screen is still being refreshsed -- so a refresh rate slightly lower than maximum, and an enlarged VBI (via various tricks -- sometimes manufacturer automatic such as ULMB -- or manual such as Large Vertical Totals via CRU). This creates longer idle periods between refresh cycles to let pixels finish transitions in the dark cycle between strobe backlight flashes. Strobe crosstalk is the resulting visibility of incomplete LCD pixel transitions that overlaps at least two consecutive strobe flashes.
Simple end user answer: Lower your refresh rate to reduce strobe crosstalk, and:
-- Additional step #1: For monitors that don't do large VBI automatically (like ULMB/LightBoost does) you may need to a Custom Resolution Utility to create a Large Vertical Total.
-- Additional step #2: Adjust your strobe phase ("Area" setting or via using Strobe Utility) for lowest strobe crosstalk in the screen centre.
Sorry For that late reply, And I can not read PM at my carry forum levelFalkentyne wrote:Because I was asking him a personal question. And I don't want to post personal information publicly. Sorry. And I already mentioned the answer here anyway. It's in the XL2540 thread under OD Gain (Factory menu) with screenshots there.
My origin 2546 is send to the BenQ in the day I post this issue
Because it is defect ,A light line cross over the monitor when DyAc on Premium

And the new one just arrived to day with the Taiwan region BenQ manager and his sidekick
He pick up a "perfect"(no defect) one for me , looking like a CES exhibition level quality
The contrast is much better they first one and the color is more accurate too (same setting)
when I turn off the AMA in the Crosstalk Test this one is almost no dark blue shadow near the UFO
(even the air temperature is lower)
every thing looking great , But the DyAc have not change
still inverse ghosting ,Even my XL2420Z Blur Reduction have less ghosting
I don't know the SRGB he force to not tell me , But the yellow looking like my old ASUS 6-bit TN monitor
other color is looking near same with XL2420Z
As his attitude and he force to not recognition the defect so he don't have to eat his words
(He tell me before , If new product have defect they you will have a free upgrade)
So I ask he to take it back also refund.
Now I was thinking to get Samsung 1 ms MPRT monitor
If the TN will have ghosting I thing all LCD will have too
Just looking for more clarity on dynamic and bright around 200/nits when low blurry tech on will do
Now I can get
ACER XZ271 A
MSI G27C2
MSI AG32C
Did not on market yet
ACER XZ271 U
MSI MAG27CQ
Samsung C27HG70
Did any one know where can I found the brightness date of 1 ms MPRT mode on?
p.s my 2546s looking like this but the Alien face is more clarity and the ghosting is more fade out feel
and XL2420Z looking like this almost same
