Not necessarily. BFI sequences isn't necessarily an indicator of refresh rate capability.
It can, but not always. There are sub-refresh BFI techniques.

Great line. Totally agree.
This is very interesting, i wonder if can be implemented in last gen Samsung AMOLED HOP screens. HOP is a new matrix for OLED optimized by Samsung to save energy, based in Apple LTPO. Samsung Galaxy S21 Ultra claim 6.8" AMOLED-HOP QHD 120Hz with peak brightness 1600 nits ! If they can do it with only ~7", is supposed to be more easy and cheap to manufacture it with 4x higher pixel size = ~27" monitor size. If i'm not wrong, bigger OLED pixel = less probability of pixel manufacturing issues. This is at least what LG claim to be unable to make OLED TV 4K less than 48"
For many HDR OLED screens with peak brightness ratings like this -- 1600nits is often a HDR1%-HDR5% window. Basically, only a few percent of pixels are allowed to peak at 1600nits for HDR purposes. If you have seen a proper HDR display you understand -- e.g. sun glints on a chrome car, neon lights at night, or starry sky in space, etc. HDR nit peaking is only for highlights. Often, this nitpower is not often concurrently for all pixels simultaneously, due to the way the OLED screen is engineered.AddictFPS wrote: ↑27 Dec 2020, 11:13This is very interesting, i wonder if can be implemented in last gen Samsung AMOLED HOP screens.

If can be implemented like LG CX with BFI 4.16ms MPRT, 1600 nits double peak brightness of LG CX. Would result, using Samsung BFI equivalente to LG Motion Pro High, 60Hz single strobe 60@120 nits, and 120Hz single strobe 120@240 nits. Very interesting for the 60Hz single strobe thread, 60nits is a bit dissappointing, but 120nits is a decent level, even with the same brightness cap (equivalent to LG CX ABL).
Like allways, new OLED devices are not inside monitor market but i think these new screens would be amazing also redesigned for monitor and laptop. None word about how this new brightness level affect burn-in wear speed, it's suspicious behavior, the most wanted spec is hided Should be mandatory a universal spec than measure this wear speed for each OLED color, currently user is blind in this aspect. So i'm a bit sceptical of these 1600nits marketing claims. If Samsung realy trust in a very good bunr-in resistance in this new gen screen, should prove it, Odissey G monitor with AMOLED BFI at CES 2021 would be a good start

Alas, it is much easier for LCD.thatoneguy wrote: ↑02 Jan 2021, 13:57To get 1ms persistence blur 100 nits @ 60hz for SDR while strobing we need at least 1000 nits at 100% window(and even more than that if using shaders for retro games).
How far away are panels with 1000 nits/100% window?

1. I'm pretty sure they're achieving that at a higher refresh rate than 60hz though no?Chief Blur Buster wrote: ↑04 Jan 2021, 01:13Alas, it is much easier for LCD.
1. Voltage boosted strobe backlights has already achieved the 300nit 1ms LCD (BenQ DyAC XL2546 series).
They still achieve ~150 nits at 0.5ms MPRT.
2. 1000 nit LCDs are already here.
