I think the XL2720 works similar to the XL2411p, right?
XG2431 and XL2411P has an adjustable strobe phase, but XG270 does not.

That can affect strobe lag, depending on where you place the Leo Bodnar (top, center, bottom)

So I thought that the results could be extrapolated to the XL2411p and, therefore, since the XL2411p and the XG2431 are very similar, we would then have an approximate measurement for the XG2431.
You cannot extrapolate an unadjustable-strobe-phase monitor to an adjustable-strobe-phase monitor. I can only compare XG2431 and XL2411p reliably generically from strobe phase mathematics.

The VSYNC ON 60Hz strobe lag differential can be RANDOM(0…1/60sec) for a random unadjustable-strobe-phase monitor, depending on how its strobe tuning is done.

5ms is within the range, but it could just as easily be 0ms or 16ms for a random given monitor that does not have a Strobe Utility to adjust your latency-vs-strobe-phase tradeoff.

XG2431 and XL2411p is two different species of apples because they both behave similarity on scanout velocity, large vertical totals, and both use the same generic industry standard strobe tuning methodology, and thus is easily mathematically latency mappable to each other at identical settings. But XG270 does not have a Strobe Utility, and it’s also a fixed-horizontal-scanrate panel (XL2411P and XG2431 are both variable horizontal scanrate) so it’s comparing apples vs oranges in latency, as the panel behaves differently — even if lag number is identical for one benchmark, lag number can be very different because of the differences in adjustability or differences in fixed/variable scanout velocity capability.

Don’t forget Leo Bodnar (a 1080p 60Hz VSYNC ON lag tester) can display 3 different lag numbers depending on which flashing square you put the Leo Bodnar sensor on. Most reviewers use the center, though.

I will move these posts to a new thread if there are further questions, since this starts getting offtopic from the POV of XG2431 thread.

Hello Chief!

I think there has been a mix up with the monitors.
I was not referring to the Viewsonic XG270 but to the Benq XL 2720.

In a famous website I saw that the Benq XL 2720 gave the following result (with Leo Bodnar)

Blur Reduction off:

Top: 2.6ms
Middle: 10.0ms
Bottom: 17.5ms


Blur Reduction on:

Top: 6.7ms
Middle: 15.0ms
Bottom: 23.3ms


Sorry for the confusion. Maybe I expressed myself wrong.

I don't know if this changes anything of all the reasoning that you have exposed before.

Thank you very much for your answer, Chief!

Upgraded my gpu from rx 580 to rx 6600 which runs at pcie 3.0 x8.

And I haven't been able to switch to 60hz 4500vt (594mhz) mode. I thought it might have to do something w/ pcie bandwidth but it's able to work w/120hz 2250vt(594mhz). I guess it's unrelated and card just can't handle the large vertical totals?

Honestly haven't had time to experiment more and look more into see what I can do yet. But thought I might ask jic somebody had a quick answer.

Ooops -- good catch. I misread. This being the XG2431 thread, talk about BenQ-vs-BenQ threw me off by accident.

That is somewhat of an odd result, but this may be precipitated by strobe crosstalk. I'd be interested to know what the Strobe Utility and Vertical Total settings were for this specific test. (A good topic for another thread)

Lock the radio button on Pixel Clock in ToastyX CRU. Keep incrementing VT until it stops working (some people can get it as low as ~65 Hz VT4150-ish). Get it as large as possible, then once you can't go bigger, move the radio button to let yourself edit the refresh rate. This is an exception.

Another method is trying VT4640 (exactly 4x the 240Hz VT), by modifying the original 240Hz mode, instead of modifying the 120Hz mode. Don't forget to lock the radio button on Pixel Clock while Hz is still 240.

Hi all, I did some more search on monitors. The XG2431 has caught my attention since it looks to have good clarity and is a good contender to the XL2456K. The only thing I seem to be concerned about is brightness; I would not like it if my screen was too dim and I had problems tracking enemies. Is there a solution to resolve this?

The nits of XG2431 strobe is not as bright as the nits of XL2546 series. The XG2431 is way more configurable, but there is not as much voltage-boosting going on (for wear-and-tear reasons) in the XG2431 strobe backlight mode.

Everyone has different preferences in brightness, but if you already use XL2546K at maximum DyAc brightness, you might not want the brightness decrease.

I don't have a BenQ monitor; instead, I'm still using an older ASUS 144hz 1080p model. At this point, anything is an upgrade, although I'm concerned about the price and performance. Because of its cost and similarity with the XL series, the XG2431 is most certainly my best option.

I believe Chief said that all of the MSTAR based Benq monitors are variable multi-sync, while the Realtek Benq monitors are fixed scanrate.
The Realtek ones are the XL2735/Z, XL2730/Z, XL2546K/S, XL2540K/S, and XL2746K/S.
There may even be an XL2740 floating around.

The Mstar monitors are the non MBR XL2411T, 20T, 70T (lightboost era), XL2411/Z/P, XL2420/Z, XL2420G and XL2720/Z. The XL27430T is also Mstar and MBR, despite the "T" instead of a Z. Benq made some changes to the OSD with this new "T" version, combined with a whole buttload of new bugs that required many firmware upgrades to fix.

I am NOT sure but I think the XL2540 and XL2546 are also Realtek.

None of the realtek monitors can single strobe below 99 hz.

The XG2431, after reading all the above, I consider it to be the definitive monitor to play on console!

I am European (Spanish), and there is still no information on when it will arrive here.

I'm thinking of buying it imported through amazon.

Chief, tell me what would be the link through which I support Blur Buster with my purchase !! I am very grateful and I want to support you
