There are GtG curve shapes, and GtG heatmaps, where refresh rate compliance 100% looks worse than refresh rate compliance of 75%.

LCD GtG is often a curve that looks like this:

. . . .

I think we're aligned that overshoot, consistency, and curve shape all matter. However, my question is strictly about a fixed refresh rate, fixed FPS, and the best usable overdrive with no visible overshoot, for example in a competitive FPS like Overwatch running at constant 240 FPS, not in an application where I'll be switching between 240FPS games and low FPS games.

In that situation, refresh rate compliance directly reflects whether the panel can physically complete pixel transitions within the 4.17 ms refresh window at 240 Hz, right?

If one panel achieves ~80% compliance, most transitions complete within the refresh interval, so pixels reach their intended value before the next frame, resulting in motion clarity "closer" to true 240 Hz behavior.

If another otherwise similar panel, still at fixed 240 Hz and optimal overdrive with no overshoot, only achieves ~30–40% compliance, then most transitions extend beyond the refresh interval. This means pixels are still transitioning when the next frame arrives, which should produce more trailing and reduced motion clarity.

So in this controlled scenario, is it correct to say that the panel with higher refresh rate compliance will objectively produce clearer motion, simply because more transitions complete within the refresh window?

For example, if one display achieves ~60% compliance and another only ~20%, with both having clean overdrive and no overshoot, the 60% panel would objectively deliver clearer motion, correct?

I understand that refresh rate compliance alone doesn’t tell the whole story, and that the full GtG heatmap and full OSRTT data are important to evaluate overall behavior. But at a fixed refresh rate, compliance still seems to be a direct indicator of how fully the refresh rate is physically utilized.

Let's look at the two screenshots below, it will help me understand better. We agree that this MSI is "bad" here, right? (I remind you, I'm talking about stable 240Hz/240fps use on a game like Overwatch.) Here, the OD Fast is the "best OD," because the next one, which is the last OD, has too much visible overshoot.



Here, the Zowie seems better, right? 50% R.R.C and "inverse ghosting rate" only at 1.8%, technically, in stable 240hz/240fps use, the Zowie is "better" if we base ourselves on this metric, right?



If my reasoning is still wrong and incorrect, please explain why using the two images above, and what exactly should we look at in these images to know if it's "good or not"?

Be mindful that the AOc Q25G4SR successor (a 24" QHD +360Hz panel) is coming out to EU by the end of Q1 2026.

I wanted to revisit this information; I've searched everywhere but still no sign of the AOC 24-inch 1440p 360Hz monitor. Where did you see that?

The only new monitor that i found is the AOC 25G4KUR which is a 1080p, not 1440p.

I really want to buy it.

I've missed the date by a small bit :p
It's likely coming in Q2 2026.
The panel in question is the BOE DV245QH1-B02
Models, implementing the aforementioned panel:
Titan Army X256T, P245MS Pro
Sanc K55
Viewsonic VX25G26-2K-4

AOC is highly likely going to be releasing their competitor with this panel at some point... at least that's what I'm hoping for.

Thanks, but where did you get the information ? I mean, how do you know AOC is going to implement it? I couldn't find anything on TFT Central.

In the meantime, I tried a QD-OLED 500Hz (Acer X27UF5BMIIPPRUZX), and personal anecdote:
I prefer so much Samsung QD-OLED panels to LG OLED panels; that's definitely the case for me.

I don't get any major headaches, however, the text fringing is still there and bothers me, however, I noticed that between this QD-OLED 500Hz and my Zowie TN 240Hz (without strobing), I don't see any real benefit in motion clarity or responsiveness; it's even strange to say, but I even slightly prefer the experience on the Zowie (especially because the panel is less harsh for my eyes), yes, the QD-OLED performs better. With an OP1 8kHz V2, it's very good, but I was clearly expecting more, given how people's like Optimum and Monitor Unboxed talk about it as almost a game changer.

I still have hope for QD-OLED; I'll probably try a 4K 240Hz model after that, which would maybe reduce the perception of the text fringing.

I know I'm bothering you with my idiots questions, but I'd like to bring up my last questions on this subject; it would have helped me to understand better, with their graph/test.

In essence, I don't have a confirmation, I just hope it'll happen and I'm relying on AOC Q25G4SR dates
There's even a chance that AOC won't release such a model this year

People still forget that OLED is bound by sample & hold, which means that you can only get as much clarity as the 2D/3D content can provide
There's been a large push for OLED by mainstream reviewers, but they always somewhat forget to highlight this 'limitation'

Okay.
I'll reiterate my request to finally conclude this thread, since I haven't received the important answer I'm waiting for.
Could you clarify what I'm asking in my message of "01 Mar 2026, 13:59" regarding the Monitor Unboxed example please?

Zowie objectively better in this case, if we look at "Response Time" graph for G274QPX, many orange and red squares with numbers way above 4.17ms (which is refresh window for 240hz, didn't reach target color in 4.17ms? sorry, move to render next frame).

G274QPX (17.3% R.R.C) with the rest way above 4.17ms = not good, blurry
XL2546X (50% Refresh compliance) with rest closer to 4.17ms = better

When Response Times and Overshoot are similar it gets complicated, hence why looking at GtG curves or faster Ghosting UFO tests can reveal than one monitor looks clearer or suddenly has inverse ghosting.

Because in practice when we flick the hell out of our mouse in an FPS game like Overwatch to switch target for example, neither of the LCDs might reach the target colors in time, but one can reach close to the right colors earlier before it needs to switch to next frame.

Probably because g-sync pulsar, they recently released 360 Hz IPS panels, because pulsar is exclusively LCD based techonology right now.

The XL2540X+ actually does make sense, since it's G2G RTs are better than your current monitor. Should lead to a slightly better backlight strobing experience.
It's likely using the same panel as the 66X+, just downclocked.

I just reread this section, since I'm going to try out some new TN monitors in the coming weeks (even though I've already tried three OLEDs since then).

So, can the XL2540X+ really do strobing?

I mean, I just looked at/compared the model numbers, the price, and the logic behind it all, and it doesn't make any sense (to me). I mean, we have:

- XL2540 - 240Hz (older, discontinued, no strobing version)

- XL2546K - 240Hz (older, discontinued)

- XL2540K - 240Hz (exact same panel as 46K but without extra accessories??)

- XL2546X - 240Hz (discontinued, probably due to the high dead pixel rate report? idk.)

- XL2540X+ - 280Hz (exact same panel as 46X+ but without accessories?)

- XL2546X+ - 280Hz
(the same as the one above but costs €141 more)


Now the big question:
Does the XL2540X+ are a XL2540K with newer panel and +40hz more or it's a XL2540-like without strobing ?

I mean, the XL2540X+ cost 141€~ less because it does not have extra accessories ? or it have slightly less performance (both strobing/G2G)

Edit: I just noticed that on the Zowie website, they claim that the XL2540X+ does not have strobing (DyAc).



BUT, on this video: https://www.youtube.com/watch?v=DAEUb-UHGJA, it apparently have accessories and strobing, wtf.
