Do we know if the XG2431 is dimmer when using it's motion blur tech? That strobe utility screenshot is ridiculous. I'm going to return this BenQ now and buy the XG2431 instead if it isn't dimmed!
Well, I'm sure it will be dimmer, unless they're somehow driving the LED backlight harder during the strobing mode. Otherwise, it will always be dimmer, since your screen is essentially turned off for part of the time.

I understand that the strobing modes will generally lose a lot of brightness, I just wish they would still give us decent brightness in strobing mode. I mean, I think after I calibrated my BenQ XL2411P in the single strobe mode at 60Hz I only got something like 39 cd/m² and that's with the panel brightness turned all the way up.

If I could get near 100 cd/m² while using a duty cycle that gives around 75% blur reduction it would be awesome. I think I'm using a duty cycle setting of 08 on my XL2411P monitor.

If you're going to put a high quality strobing or BFI feature in your monitor--first of all, it's really appreciated--but just make sure you have enough brightness overhead to still give enough brightness in the strobing modes.
PureXP+ on XG2431 now lets you adjust strobe duty cycle in 1% increments from 1% to 40% of a refresh cycle under “PureXP+ Custom”. I can get significantly over 200 nits easily at 40%, so it does exceed 100 nits at 25% duty cycle, considering XG2431 supports humongous Vertical Totals (VT4500 was successfully tested at 60Hz) which gives enough time for relatively crosstalk-free 25% duty cycle at the lower refresh rates.

There is a light amount of voltage boosted strobing, not too excessive to burn out the LED’s, but exceeds 100 nits at 25% duty cycle.

PureXP+ Ultra = 10% duty cycle
PureXP+ Extreme = 20% duty cycle
PureXP+ Normal = 30% duty cycle
PureXP+ Light = 40% duty cycle
PureXP+ Custom = adjustable in 1% increments from 1% to 40% (via Strobe Utility)

It is always a brightness-vs-MPRT/persistence tradeoff for all strobed monitors, even DyAc gets dim if you adjust pulse width down (MPRT) in the BenQ variant of Strobe Utility. MPRTs can get as low as approx ~0.1ms albiet very dim, while MPRTs of 25% refresh cycle (4ms at 60Hz, 1ms at 240Hz) will be quite usable at triple digit nits. A 25% duty cycle requires the “Custom” setting, of course. The wide custom adjustable-MPRT range means you can strobe brighter (and slightly less clear), or strobe briefer dimmer (but clearer motion) — you choose the tradeoff.

A lot of old LightBoost fans -- from almost ten years ago -- used the LightBoost 10% feature (see LightBoost 10% vs 50% vs 100%), but that was strobe length duty cycles only down to 1ms MPRT persistence, where the XG2431 can go all the way down to approximately one-tenth of persistence of LightBoost 10% if you wanted.

Also, this is a variable-scanrate panel (aka low-Hz friendly), so this is low-lag for gaming consoles too — one of the lowest-lag 60Hz and 120Hz capability I’ve seen in any 240Hz 1ms FastIPS panel.
Wow, thank you, this sounds excellent. With the extreme degree of user adjustability and the low input lag it seems like it will be an incredible monitor for both PC and console gaming. I can't wait for the official unveiling on the 9th.

BTW, ViewSonic is planning to have their own separate announcement sometime after April 9th, but we've been authorized to announce the Blur Busters Approved related stuff for April 9th.

That was quick — there is already 19 votes. Needs at least 100+ votes.

One neat thing about this model is that it is Blur Busters Approved out of the box — no need to wait for a firmware upgrade first.

The RTINGS methodology is a bit boilerplate as they will usually photo only max-Hz strobing, where I’d like to see them modify methodology to show pursuits at multiple BFI Hz. However, since XG2431 supports 60Hz single strobe, it will rate high.
Yes, that is impressive. Now 22 votes in less than 24 hours.

We could ask them to do some extra pursuits. I believe they would do it since its specifically tuned for bfi and that sets it apart from others. We just need info on which refresh rates were tuned (60, 120, 240?) I can send an email before a review and we will see.

They won't know how to test it they way it's intended to be used. this monitor essentially needs custom resolutions with large VT's for it's strobed modes to function adequately.

rtings blur-reduction testing is extremely inadequate. We need much better monitor reviewers like a a5hun from https://www.aperturegrille.com

The good news is you don’t need Strobe Utility or Large VTs. XG2431 has vastly better 240Hz strobing out-of-box than XG270.

At 240 Hz, I can get darn near crosstalk-free for the exact screen middle, not too dramatically different from an XL2546 series (Give or take). I couldn’t do that due to panel limitations of XG270. There’s a tradeoff of crosstalk increasing for top/bottom edges the higher refresh rate you go, but this is true for practically any strobed monitor you buy. But the strobe quality now exceeds XG270 for 240 Hz out of the box! Darn near “best TN quality” strobing I’ve seen on any 240Hz IPS panel.

So you have best of both worlds for both easy and advanced users:

- EASY Improved strobing out of the box (for high refresh rates); AND
- ADVANCED Further improveable strobing via Utility + Large VT (for any refresh rate, especially lower refresh rates)

Users don’t need to download the Strobe Utility if they just want 240 Hz strobing, as it’s darn near already maxed-out quality at 240 Hz tuning (since 240 Hz doesn’t support large VTs anyway — most 240 Hz monitors are unable to support large VTs at max Hz anyway)

Nontheless, no 240Hz IPS panel supports any-Hz strobe (60-240), so this makes XG2431 the world’s most flexible strobed monitor at the moment.

It’s true RTINGS should update their motion blur reduction tests — they are great in standardizing motion blur tests, but sometimes they’re a bit too standardized for the advanced nuances of Blur Busters Approved (optionally using Hz headroom to create better strobing).

No worries, the RTINGS rating will be extremely high anyway due to strobe-any-Hz support (complete 60-240Hz continuum, any custom rez you want), since their boilerplate checkbox-based test methodology.

I hope availability will start next week. ;)

I have till about the 19th of April to return the Alienware 240Hz.

I think you should. 120Hz strobe at VT2250 or 60Hz strobe at VT4500.

Enhancements to Strobe Utility will now come more rapidly over the next year, since I’ll be reusing portions of an old configuration utility I wrote but never released. That has some goodies that will be rolled into this utility.
