Does it make it any brighter? Can you turn up the Brightness more when set to Premium or something?
Does it effect the crosstalk or ghosting of the UFO test?
Getting less crosstalk at 240hz is very strange.
The picture settings sound good in standard, most of the settings are just for customization and for making your screen look funkey. You might get some use out of Black Equalizer but i find pretty unnecessary.
The brightness seems the same between Premium and High, I can't really tell any difference. There's a bit of crosstalk at the very top and bottom, but they appear similar.
In 100/120/144, the crosstalk at the top and bottom appear way more pronounced and you can see there's a difference between the crosstalk at the top versus at the bottom. In one the image is lagging and in the other it's ahead, if that makes sense.
I think what's happening is that 240Hz is such a high refresh rate, the strobe crosstalk is less visually overlapped giving the illusion of less crosstalk.
Like here's the crosstalk at 120:

At 144:

At 240:

I installed the BenQ strobe utility. I'm not sure whether it starts with the default settings in the monitor or the program's own default? After I change anything, the monitor 'remembers' that as the new profile for 'Premium' or 'High' (Whichever was enabled when I ran the utility). To get back to the original settings, I reset from within monitor's OSD.
So when it says 2.5 persistence and earliest strobe phase, is that the utility's default or the monitor's default?
I can see now that the clearest band is actually a few rows from the top and not in the direct middle. It's right below the dark crosstalk band at the top. I'll try to use the utility to move that around.
Should I try messing with vertical totals? What kind of settings should I use?
From the comments of strobe utility page:
NOTE: Although Blur Busters Strobe Utility doesn’t support all BENQ/Zowie gaming monitors — However, it should be noted that the new 240Hz BENQs such as BENQ XL2540 or BENQ XL2546, both support Vertical Totals of over 2000 during 120Hz operation. In this case, it forces a 120Hz refresh cycle to scanout in 1/240sec. The 240Hz XL2540 (which has a strobe mode accessible via Service Menu) -can go up to approximately ~175-185Hz strobed without too much strobe crosstalk.
In another page, this seemed to explain the entire idea very well:

Which is to use the higher pixel clock capability of the monitor at lower resolution (so, higher VT).
I'll try the 182Hz setting listed there as well.
