Viewsonic XG272-2K OLED - BlurBusters Verified? BFI?

[tong]

And the ASUS monitor with strobing got bad red from unboxed because something regarding the black frame being terrible

Surprise, most people dislike BFI because sacrificing VRR is needed and it also impacts brightness levels, in an era where 250 nits is considered "dim".

The real advances in blur reduction will only happen when G-Sync Pulsar hits OLEDs.

I don't think Blur Busters has anything to do with BFI feature on this model. Blur Busters Verified is certification for ideal sample-and-hold modes (240+ Hz with excellent refresh compliance). But who knows... it sure seems like Chief did some assistance because of the 60 Hz support and advanced "BFI Strength" option.

Not really, Blur Buster 2.2 approval would mean it could do 60 HZ strobing which is quite useful for a lot of people.
We just have no way to know if it actually supports this

According to user manual Minimum Hz can be adjusted in 1 Hz increments between 48-120 Hz. So 60 Hz should work. Kudos to ViewSonic for that! I suppose it's single-strobe at least at 60 Hz, because of Blur Busters influence from before.

Investigating further:

120 Hz max reveals minimum achievable MPRT is equal to max Hz MPRT (1000/240 = 4.2 ms), which goes in line with current oled limitations. That's kinda fine if u need 60 Hz strobing, but meh for 120 Hz. 1 Hz incrementals also reveal it might supports custom resolutions.

BFI Strength is probably similar to pulse width, but it's not a percentage of refresh cycle like with classic bfi/strobe modes. Maybe something like:
100 = more blur reduction = less brightness = minimum MPRT (maybe fixed 4.2 ms)
50 = less blur reduction = more brightness = maximum MPRT (maybe 6.2 ms @120 Hz, 10.4 ms @60 Hz, 12.5 ms @48 Hz...)

All in all, MPRT is kinda crappy and brightness might be crappy as well. I personally wouldn't be too excited about this generation of bfi on oleds. It feels like strobing for the poor on expensive monitor unfortunately.

Not to resurrect an old thread, but still no reviews of this that analyze the BFI. I think you’re on the right track but my personal believe is that Minimum hz is content fps in a 2x fps container. And Strength is adjustable rolling scan ala LG. My postulation is that at 120fps(240hz BFI) at 100% strength, you would be at 2ms MPRT equal to the LG CX and better than the LG C1. Basically it may do both true BFI + Rolling scan.

That said I really wish the upcoming 600+hz OLEDs did hardware beam simulator. Adjustable black frame insertion + adjustable rolling scan. Enabling 60fps content (or whatever fps u desire) to have lower persistence than max hz. Why they haven’t focused on this is beyond me. Would be an easy buy for gamers

The upcoming panel-based BFI from LG might enable manifacturers to chase this route.
Though, I don't expect any vendor to do a good job & implement it for refresh rate the user desires or implement a 10:90 or 20:80 visible-nonvisible frame ratio.
Let's hope that they'll also release a FHD 24" 1kHz OLED in the next years.
We have the cable BW for them...
