Intensity is (I think) persistence (clarity; lower persistence=darker screen=clearer motion because the strobe refreshes are faster).
Same thing as "strobe duty" on the Z monitors, but this was only adjustable through the service menu (or the windows utility) on the Z monitors.

Area is the same thing as "strobe phase". Area 0 puts the top crosstalk (thick double image ghosting, aka "strobe pulse") border as close to the top of the screen as possible. It goes farther up the screen the lower the intensity is; 003 intensity should have it almost completely off the top of the screen. I find 006 (intensity) to be the best value IF you are using the vertical total 1500 tweak (or 1350) ,then 006 corresponds to a 1ms persistence, and 006 (1ms) pushes the top of the strobe pulse high enough up, while keeping enough brightness to look decent. If you are not using VT tweaks, then 010 is 1.0ms (at 100hz).

Using Vertical Total resolution tweak of 1500 will move the bottom crosstalk (strobe pulse) field completely OFF the bottom of the screen

so what is better for me 1350 or 1500 VT trick.. it just works only on 120hz or on 144hz too?

i did single strob on, VT 1350 trick and turn motion blur on and my screen is only little darker then without blur.. i have brightness set to 39 :/

hmm wait....what refresh rate?
And -always- use brightness 100 if you are using blur reduction! Brightness 100 with blur reduction and persistence at 1.0ms (if you are using a VT tweak 1350/1500; I use 1500, this makes strobe duty (persistence) 006 (1.0ms) with blur reduction on look about the same brightness as Brightness 20 with blur reduction off.

The brightness 30 thing was for that 50hz single strobe test that I'm waiting for.

[Falkentyne]

When enabling blur reduction the screen goes black and I can see a kind-of silhouette of the windows that are open. The 50hz setting didn't save with CRU so I just added the 1080p50 preset; didn't notice this in CCC before.

Is this what you expected?

Oh, no,
Set area/strobe phase to 0 (zero).
What 'should' happen is that the strobing will not work at ALL and the brightness will jump in intensity; brightness 30 will look the same as brightness 100 in another refresh rate with BBR turned off.

so in service menu i set 0/0 strobe and phase?

Alfie was trying to see if 50hz single strobe was working or not, but he has to set strobe phase (area) to 000. I think using any value higher than 014 makes the backlight shut off at 50 hz. This behavior Is abnormal; backlight shutting off usually only happens with Vt tweaks (example, with VT 1500 tweak @ 100hz, backlight will shut off at Area 60 (strobe phase 060), but without VT tweak, you can go up to strobe phase 100.

AlfieJPalmer your monitor didn't blow up or anything right?
j/k, are you still here?
I have a feeling 50hz single strobe will fail to work. (VT tweaks at 50hz is not really 50hz single strobing .it's *60hz* single strobing pulses at 50hz because VT Tweaks that make the screen go out of specification force 60hz backlight pulse widths)

Haha, no it didn't blow up

I'm new to all of this monitor stuff so please bare with me! I've not actually tried any of the VT 'tweaks' at all.

When I was testing, I set the frequency to 50hz @ 1920x1080. Single strobe was [ON], Blur Reduction was [OFF], and I'm pretty sure that I left 'Area' on 007; does this still apply if Blur Reduction is off? I should be on for much longer tonight if you're around. Would be great to learn more about this stuff. So what exactly should I try?

-> 50hz
-> Blur Reduction [OFF]
-> Single Strobe [ON]
-> Area/Intensity [0]
-> Blur Reduction [ON]

Thanks in advance.

None of the strobe settings apply if blur reduction is off. Just you may see some faint inversion lines on the desktop if using VT tweaks.

But what was supposed to happen is, when using strobe phase 000 (area 0), and 50hz single strobe, turning on blur reduction should cause a MASSIVE increase in brightness with no strobing activating at all. If the brightness is at 100, the LEDs will be massively overdriven. So I wanted you to try 50hz with an area (strobe phase) of 0, and something like a duty of 10 or something.

At 60hz, strobing will work and the screen will darken by a lot (and you'll get lots of flicker).
If 50hz single strobe were actually working, you'ld notice it instantly..the screen would darken by a lot (depending on the intensity (strobe duty) and the flickering would be --much-- worse than at 60hz--you wouldn't be able to tolerate it.
