ViewSonic XG2431 Discussion Thread [Blur Busters Approved XG2431 - 24" 240Hz IPS with Best Strobing]

[nihil]

Is there news for the 1440p model?

[hambaby]

gotta say, the clarity on this monitor is no joke, i am absolutely in love with this monitor, my question is, anyone have any strobe utility settings that ya'll use that is between Ultra and Extreme? I find the ultra to be a little too dark while I feel like i have some brightness I can give up when im on Extreme, a sweet spot between those, i use 240hz with 390 FPS on overwatch. Also I would love to see the difference in UFOS betwen Extreme and Ultra, anyone got those pictures???

Edit: Also is there anything else I can do to increase the brightness with PURExp enabled? for example my old asus had a black boost i would crank that up to mitigate the dark screen from ULMB

[chandler]

I actually am about to order this monitor, how bad is the no-gamma-adjustment setting issue?
I chose it over the XL2546K and I wanna be absolutely sure of my choice

How is the strobing on consoles without the blurbusters utility? I'm sorry if it's been shown or asked before. I have the XL2411P and I hope it has less crosstalk than what I have already.

Better than all the single-strobe 60hz TN panels (including XL2411P) in my experience.
You won't derive benefits of large VTs with consoles, but that's the same problem on XL2411P.

Thank you for the compliment!

Light = Strobe Pulse Width 40%
Normal = Strobe Pulse Width 30%
Extreme = Strobe Pulse Width 20%
Ultra = Strobe Pulse Width 10%

In your case, you would want a Pulse Width of 15. Once you do that, adjust everything else based off that.

The ideal perfect Overdrive Gain varies by user, because it slightly varies with panel temperature and panel lottery (by a few points), so other people's settings may not perfectly match your ideal settings. Colder panels in winter will require a slightly stronger overdrive gain. Follow instructions at www.blurbusters.com/xg2431

The Pulse Width is the brightness method. You trade between motion clarity and brightness.

With the Large Vertical Total (QFT) trick, you can get less strobe crosstalk at brighter settings, but that requires a lower refresh rate. If you hate the double images, especially at top/bottom edges, then a slight refresh rate reduction can help reduce that.

Laws of physics (Talbot-Plateau Theorem) means a tradeoff between brightness and motion clarity. The XG2431 has a light amount of safe voltage boosting in its strobe backlight, they didn't want to add too much voltage for to avoid wearing out the strobe backlight. The panel chosen by XG2431 does not get as bright as a BenQ XL2546, but the motion clarity is better than a BenQ XL2546 according to most peoples' observation -- as an example.

I. Am. Stunned. I set my VBI Total to 2200 @ 60Hz and dialed in my Strobe Pulse Width to 20, Overdrive to 5, and Strobe Pulse Phase to 83, and this looks insanely clear motion-wise.

At VBI total 2200 you can dial up to a more flicker-resistant 75Hz or 80Hz easily. The 120Hz refresh rate even works at 2200.

At 60Hz I have been able to use Vertical Total well over 4000 with my XG2431 -- which is even better than 2200. Using VT 4000+ means you also get lower strobe lag, with 60Hz refresh cycles refreshing in 1/240sec, allowing an earlier strobe flash on a more fully-refreshed LCD panel.

There is NO crosstalk! If I were to be the absolute most nitpicky, I can barely see faint (and I'm talking equivalent to CRT Phosphor trails) ghosting on the UFOs at the top and bottom.

It's not even the best you can get -- you're only using 2200 at 60Hz?

It's something that I'd only seen on my CRT beforehand. Bonus points for no phosphor trails from panning over the fluorescent lights in a dark room.

Very good calibration if you're using only 2200! I usually need Vertical Total 3000+ at 60Hz to dial the crosstalk to zero for very top/center/bottom. But it does vary slightly on panel (panel lottery in GtG variances, and temperature-based GtG variances).

The only drawback perhaps is that the strobing can be a bit harsh compared to my CRTs on brighter scenes (or excel spreadsheets) due to the lack of that familiar CRT phosphor decay, but in video watching and games it's hardly noticeable.

You should raise your refresh rate slightly, even 75Hz or 90Hz will allow most GPUs to keep framerate=Hz. 75Hz and 90Hz is much more tolerable than 60Hz. Unless your game is 60fps-locked, which means you're stuck with 60Hz single-strobe.

Suffice to say, I finally have a replacement for my Compaq MV940 and Gateway-branded VX720 Diamondtron

High compliment when anybody use Blur Busters tuned panels as CRT replacements!

Hey there,
im using currently a XL2540 as my main gaming display. How much of a difference will the jump to the XG2431 make? Thinking of ordering once it hits European store shelfs.

On a side note: Since the first batch of proper OLED gaming monitors is slowly arriving, how does the motion claritiy of the AW3423DW stack up against the XG2431? Sorry if this question seems illegitimate, I'm just wondering since OLED pixel response times are a magnitue lower than even TN panels

[Jadzira]

Is it recommended to use PureXP+ and fast sync/adaptive sync? What settings you recommend?

There are two different pixel response benchmarks, GtG and MPRT, as seen in Pixel Response FAQ; GtG Versus MPRT.

GtG’s on OLEDs is lower, but MPRTs of strobed LCDs (e.g. PureXP=ON) is lower than any of the OLEDs, whether be Rift, or LG OLED, or the new gaming monitors.

For non-strobed, OLED is superior. But for strobed, good LCDs like XG2431 still can do MPRTs better than than even the best strobed OLEDs.

Once GtG reaches near 0, there is still motion blur from display persistence (Aka pixel visibility time): www.testufo.com/eyetracking

Shortening pixel visibility time requires shortening refresh cycles, either via higher Hz or via briefer flash of Hz. For nonstrobed, double frame rate at double Hz will halve motion blur. But likewise, halving frame flash time (via a strobe backlight instead) halves motion blur without need to raise Hz or framerate. It’s also why 120fps 120Hz strobed has less motion blur than 240Hz non-strobed, too.

Eventually over the longer term, OLED may produce superior MPRTs, but Talbot-Plateau’s Law means it’s a little easier to outsource extra brightness in a strobed backlight than strobing OLED pixels directly. Turning 4ms MPRT into, say, 0.4ms MPRT (PureXP Ultra on XG2431 at 240Hz) requires 10x the brightness to maintain refresh rate, for framerate=Hz=stroberate. That’s kind of hard to do with brightness-limited OLEDs, so OLED MPRTs cant reach sub-millisecond levels like BenQ’s and ViewSonic’s can.

However, Hz for Hz, in non-strobed operation, OLEDs will always look clearer for motion. For example, 120Hz nonstrobed OLED looks better than 120Hz nonstrobed TN. This is because in an equal-MPRT-bottleneck situation (1/120sec), GtG pixel response takes over as the determinant factor.

It’s imply the fact that LCDs can strobe more brightly briefer, LCDs with good strobe tuning can get more CRT-motion-clarity than OLEDs can at this time. Especially when calibrated with large vertical totals to hide LCD GtG 100% hidden by human eyes between refresh cycles — for zero-crosstalk operation. XG2431 can go as zero-crosstalk as an Oculus Quest 2 VR LCD, with the right calibration instructions at www.blurbusters.com/xg2431

Is it recommended to use PureXP+ and fast sync/adaptive sync? What settings you recommend?

Disambiguation:
Adaptive V-SYNC: driver setting, similar to Fast Sync
VESA Adaptive Sync: a VRR technology underpinning FreeSync & G-SYNC

Fast Sync + framerate cap near Hz, can be a technique to get smoother-looking PureXP.

Even better, though, is RTSS Scanline Sync or Special-K Latent Sync (both tearingless versions of VSYNC OFF with lower lag than VSYNC ON)
