ELMB-SYNC is the only tech that officially does this, and your better ELMB-SYNC choices are limited to 1080p. Also, your non-multistrobed refresh rate range is extremely tight, but for games fluctuating near max-Hz, it can be quite beautiful.

To expand your options, you can also force framerate=Hz as explained in CRT Nirvana Guide For Disappointed CRT-to-LCD Upgraders.

Thanks.
Though am I wrong for thinking I read somewhere that BenQ had similar tech? Something about voltage-boosted strobing?

No.

DyAc voltage-boosted strobing is completely unrelated to framerate-linking. Voltage boosting simply increases brightness, and has nothing to do with framerate / stutter / jitter / crosstalk / etc.

Tech can do voltage-boosted strobing regardless of whether or not framerate is linked or not.

It is easier to link the framerate to the strobe (upgrade GPU, change sync technology, use RTSS, adjust game settings, intentionally lower strobe Hz to match framerate to gain better strobing competitive advantages, etc) -- there are several techniques possible. You can do that with DyAc if you want.

The common recommendation for framerate=Hz strobing is getting a more powerful GPU and using a "low-lag VSYNC ON" to get framerate=Hz with fixed framerate and fixed refreshrate. You're linking framerate to the Hz (User tweaking), not the other way around, Hz to framerate (hard to do without ELMB-SYNC).

1440p 144/165hz monitors with ELMB-Sync:
VG32VQ - Terrible VA smearing when strobing, black transitions are way too slow creating a dark like of crosstalk.
XG270QG - The red phosphor used in the nano ips panels causes a red afterimage replacing crosstalk, which looks horrible
VG27AQ - Bad crosstalk due to poorly timed backlight, Asus somehow decided that forcing a double strobe when using strobing together with VRR (like on the VG279QM/259QM) was a good idea, this causes an ugly smearing effect.

Pick your poison.

Let's say I only care about 200, 300+ cd/m2 brightness while strobing, what are my options? Also, can you force strobing at 90 or 100 times per second while setting a framerate limiter to 90/100 fps one of such monitors? 144 fps at 2.5K is a bit too much for many people, not to mention at 4K.

You are asking the wrong question. ;)

If you meant: “Can I configure a 144Hz monitor to output 90 refresh cycles per second (90Hz refresh rate) using high-velocity-delivered refresh cycles with a 1/144sec scanout, and then strobe the 90 refresh cycles”? Then Yes.

1. Choose a monitor where 90Hz is within its strobe support (e.g. PureXP or DyAc)
2. Create 90 Hz ToastyX CRU mode with a Vertical Total that’s 144/90ths the original (Quick Frame Transport)
3. Switch Windows to 90 HZ refresh rate.
4. Use RTSS to cap to 90 frames per second
5. CRT nirvana

It’s a little roundabout, but essentially gets what you want, a 90Hz refresh rate with refresh cycles delivered in 1/144sec apiece. And the large vertical total hits two birds with one stone (Crosstalk reduction & Quick Frame Transport for framerate=Hz operation)

PureXP and DyAc 240Hz monitors can support a strobed range of 75Hz to 240Hz. It will strobe one flash per refresh, so you need to use Custom Resolution Utility to create the custom strobed mode you need.

Be noted that strobing at a lower Hz requires a longer strobe flash, to prevent dimming. Higher-Hz strobed monitors (240Hz) will be brighter, but it’s hard to get framerate=Hz at 240Hz in many games.

Oh I get it, although I would assume introducing custom refresh into the story would result in unforeseen problems, as is the case with so much of the tech. I hope not.

If some 240 DyAc are outputting 300 nits with strobing on (presumably at 1ms lenght?) I assume strobing 90 times per second at 1 ms lenght would result in about (90/240)*300 nits = 113 nits? Are 240 DyAcs much brighter than 300 nits when not strobing? Theoretically they could reach 1000 nits+.
Is there anything on the horizon that could theoretically strobe at 300 nits @ 1ms length @ 90 or 120 Hz?

Man this whole motion resolution thing is unfortunatelly such a niche, especially here in Southeastern/Eastern Europe. You splurge whole paycheck on the 3080, you splurge on the carefully picked monitor and still you end up at incredibly dim 120-150 nits at modern unoptimized AAA games. :? It sucks.

Custom strobed refresh rates work great with BenQ and ViewSonic monitors. I expect custom strobed refresh rates to work on other brands such as the upcoming Eve monitors as well as a few others.

It doesn’t necessarily go linearly — the strobing can automatically voltage-boost stronger for shorter strobe lengths on some brands of monitors. Not all manufacturers do this, however.

RTINGS and TFTCentral publishes nit measurements. The way Blur Busters work is we don’t mass-test monitors (except Special Editions such as GSYNC 101). Wwe invent tests that are used by other monitor testers. It’s the proverb — Instead of giving fish, we teach others to fish.

Fortunately, improved motion resolution via sheer refresh rate is becoming less niche. 120Hz smartphones and 120Hz iPads. Also, 360Hz monitors have motion clarity almost as good as a strobed monitor now, if you manage to run at 360fps. LightBoost used to strobe at 2ms persistence (at LB 100%), and 360Hz has 2.7ms persistence.

But yes, low-Hz strobing is often quite niche, but you’re pretty well prepared if you get a recent BenQ or ViewSonic monitor. Unlike ULMB, you can easily create custom strobe rates via custom refresh rates, it will always strobe-match to the custom Hz. The advanced QFT stuff is optional.

Thank you for your time, you've been very helpful.

Can anyone confirm that 2411p doesn't dim when strobing? At least at 144Hz?
