One mandatory rule of a Blur Busters Approved strobe backlight is no refresh rate cap.

Max Hz must be strobeable. Some brands of strobe backlights (such as NVIDIA ULMB) limits the refresh rate you can strobe at.

A Blur Busters Approved strobe backlight (both 1.0 and 2.0) does not uses presets nor max strobe capping. You can use a lower Hz for quality strobing (quality priority strobing for better CRT emulation) or higher Hz for lower lag strobing (latency priority strobing for esports / aim stabilizing / DyAc style).

Very good, but the reviewer made one mistake:

You must retune Overdrive Gain between 144Hz and 240Hz. The pursuit camera images for 240Hz can be much better. “35” for Overdrive Gain is too low for 240Hz on XG2431, and adds more crosstalk. 35 is good for 144Hz but way too low for 240Hz.

I should add the caveat that Light adds more crosstalk to top/bottom edges. If you see www.testufo.com/crosstalk when adjusting between Ultra / Extreme / Normal / Light … the crosstalk becomes worse at top/bottom edges the brighter you get.

I would suggest reviewers test both a Light and a Normal/Extreme setting — it makes a huge difference in strobe quality.

This is what 240Hz looks like when properly re-tuned

Did some testing myself fine-tuning the OD gain and pulse phase and honestly on 20 pulse width(not bright but enough to see comfortably),15-20 pulse phase and 35 OD is the best. Increase OD any higher will cause purple corona artifact behind the ufo especially visible on 1920 pps, middle grey. On 45 OD 2nd crosstalk gets bluer(hard to spot). On 55OD both 1st and 2nd crosstalk gets bluer(easy to spot). Hence I've decided on 35. You guys with the xg2431 can test it yourself if anyone can get a better-tuned setting please share it. I do agree that 35 might be low but not too low as 35-45 doesn't really make that much of a difference and small side effects starts to appear, but once you get to the 45-55 region the side effects definitely starts to outweigh the positives.

Hey Chief. Could you tell me if the Viewsonic XG2431's sleep mode basically works like the "deep sleep" on/off setting from other Viewsonic monitors ? With deep sleep on, the monitor disconnects from Windows when you simply turn it off - whereas if you have deep sleep off, the monitor doesn't disconnect from Windows when you simply turn it off. I have a Viewsonic ELITE XG270QG that has the deep sleep on/off setting. I saw in the manual online for the XG2431 that this one has a sleep mode you can turn off. I'm guessing it's basically the same but labeled differently on this monitor.

Also, could you tell me if the XG2431 monitor is HDCP 2.2 compliant over its displayport port ? My understanding is that usually if the monitor has HDMI 2.0 ports, it'll also be HDCP 2.2 compliant at least if using the HDMI port (and an HDCP 2.2 compliant cable), and usually over displayport if it's DP 1.4. I was trying to find out more online... and apparently the XG2431 monitor has HDMI 2.0 ports but for displayport it has DP 1.2 or 1.1, so maybe it's only HDCP 2.2 compliant if using the monitor over HDMI ? or maybe it's still be HDCP 2.2 compliant over displayport too somehow ?

HDCP 2.2 compliance is important for me for 4k Netflix on PC basically even if this monitor is 1080p - since I'd have it connected to my PC along with a 4k display, and, last I checked this, all connected monitors had to be HDCP 2.2 compliant for the user to be able to watch 4k Netflix on the 4k display (otherwise you'd get a black screen or you'd have to disconnect the monitor that's not HDCP 2.2 compliant whenever you want to watch 4k Netflix on the PC).
so a bit of an update on this. I'm not sure where I saw that the Viewsonic XG2431 has a Displayport 1.2 or 1.1 port before... but well I looked more into this and actually looks like it's displayport 1.4 according to Viewsonic's full specifications for this monitor from their site if I'm reading them correctly.

I'm still not 100% sure that this monitor has HDCP 2.2, but then again my understanding is that usually the monitor is HDCP 2.2 compliant through its ports if it has HDMI 2.0 and DP 1.4. Plus I also have another 1080p monitor that has HDMI 2.0 and DP 1.4, and I can keep that one on/connected while watching 4k Netflix on the 4k monitor i got connected (while I also have others monitors that have HDMI 1.4 and/or DP 1.2 - and if I have those connected, I either get a black screen or a 1080p Netflix stream instead of 4k on the connected 4k display). I guess I'll find out for sure soon with this Viewsonic XG2431.

I went ahead and bought the monitor a few hours ago. I might keep it even if it somehow didn't have HDCP 2.2. The monitor's intended purpose I guess is more towards gaming and image clarity to be fair... and seems to have some really good strobing options and features that other monitors don't have.
another update on this for anyone wondering: apparently the Viewsonic XG2431 is HDCP 2.2 compliant after all. I was able to keep it connected and still get a 4k Netflix stream on my 4k display that's also connected to the PC.

Also, regarding the sleep mode of the monitor... if you have the sleep mode off in the OSD, as you'd expect, the monitor doesn't appear to go into sleep if you leave the monitor on nor does it get disconnected from Windows after you simply turn off the monitor (can still see the monitor in Window's display settings, and apps you had in the Viewsonic monitor don't get rearranged etc); however, apparently it does get disconnected from Windows for a moment after you turn the monitor back on - then it quickly reconnects and flashes your other displays a couple times. At least that was my experience with 4 monitors connected including this Viewsonic, and using Windows 11.

The said, I didn't see any backlight bleed on my unit (and I've been unlucky in this aspect with monitors in the past) and just a little bit of IPS glow - less than other monitors I've had. Your mileage may vary with this I suppose. Also, I like the design and how you can turn it around for portrait mode - not all monitors have this.

Seems the XG2431 has dimmer strobing than XG270 by a little bit:

Still seems plenty bright to me, maybe I am not as sensitive to dimness. Or maybe the youtube guys measurements are low somehow.

Hello boss, I think this is the question we would like to ask many, what are the "Strobe Utility" settings that you recommend for a 240hz strobe? For overall clarity, is it also necessary to set a correct value of contrast and black stabilization? If so, how much?

What’s the brightness loss like though? Based on Bijan’s video it looks like to actually be able to achieve XL2546K levels of blur reduction it loses a lot of brightness, in some cases rendering it unusable. Is that accurate? The main thing stopping me from buying a pair of these still is I can’t tell how consistently functional the blur reduction would be.
Its best strobed IPS you can buy right now. Better than Zowie in every way except strobing brightness obviously, and response time difference is negligible. Try to find out how much ∼160 nits (PXP Normal) really is. Idk what monitor you're currently using but I'll do something unreliable and assume its somewhere in between 20-50%. So if u use your monitor at those levels of brightness than no worries. For example I use my VG279QM at 15% (140 nits) all the time, same for my M32Q. I'm even fine going a little lower.

That’s good to know and makes me more comfortable purchasing them I think. I use my AW2521HF’s at 40-50% brightness but normally I use monitors anywhere from 20-30% as these AW monitors don’t seem as bright per % as other monitors I am used to.

I keep hesitating to pull the trigger on these monitors but there really isn’t anything else out there that seems to be a better purchase. Because even without strobing these are a nice panel at 23.8” which is great for 1080p. I was trying to see what good options there are for competitive fps games at the 27” 1440p level but I don’t see any good alternatives (except maybe the Omen X 27?).

If u don't need strobing I recommend cheaper S2522HG or 24G2ZU (or ZE). Aoc has strobing and its priced similarly.
