If we just interpret the word overclock, we can define it by something that is working above the clock it was designed.

I searched for that text and couldn't find anything.

Innolux 23,8'' M238HHJ-K70 = 200hz = Asus XG248Q.
AUO 24,5'' M250HTN01.0 = 240hz = Dell AW2518HF.

I believe the confusion lies in how news were written.

b) Finally we have seen a 23.8" sized monitor announced in June 2018 by Asus, the ROG Strix XG248Q which has a 240Hz native refresh rate TN Film panel.

The native 240hz is refered to the product with a TN panel, meaning will you have 240hz when you plug it, not that the panel is 240hz.
And when Asus says this is the first native 240hz they mean the first 23,8'' size.

With what Chief said above, does it really matter if the panel was overclocked if we get a product that actually works better than a true 240hz native panel?
Take ViewSonic XG2402 as an example, it uses a 120hz panel, yet it behaves as good as some 240hz monitors.

All sites i saw show this panel version as 200hz. The information is supposed to come from the model datasheet.
Same panel with different versions can have different hz, don't know if this is the case.
Hope someone with knowledge can clarifiy the information about the panel.

Notty_PT did you try the G-sync with your XG248Q ? If yes, is it as good as standard g-sync monitors ?
I want a 240hz to replace my PG248Q but i also want a good adaptive-sync experience.

i am pretty sure it has one of the best adaptive-sync exp. that is out there since it is one of the few monitors that is supported by nvidia officaly

It has almost perfect experience. No flicker or brightness problems. But if the framerate drops too much you will have overdrive annoyances. This model overdrive varies agrssively between 240hz 144hz and say 100hz.

With that being said it is listed on nvidia website as officially supported but I would still prefer to stay in high framerates terrain with this panel. If your hardware or the games you want to play cant sustain an upper 170/180fps territory I wouldnt go for it if you care about Gsync.

If you will hover around the 180fps-240fps interval you will have an amazing almost unmatched experience.

The input lag is very fast at any refresh rate, but the ghosting, once you drop lower than 144hz is higher than some IPS I have tried. At 200hz/240hz nothing that Ive tried can match it.

Why that happens tho? I have no idea, maybe they didnt bother optimizing overdrive at lower refresh rates. Idk.

Notty_PT does the monitor has something like color vibrance and black equalizer ?

Alright i'm going to stick with my pg248q for now.
I'll wait for a g-sync version. Maybe if Nvidia work on an optimized module for this panel they can fix the overdrive issue.
I'm also going to keep an eye on the new 0.5ms panel and see if they are going to release a G-sync monitor with it.

yes he have but the overdrive feels fast in start but in other day its feels lazy ELMB makes overdrive more worse but less motion blur could be add little input lag to cause mouse movement worse on elmb i suggest if you take the xg248q use adaptive-sync and overdrive 3-4 to get much better gaming experience

99% of FreeSync monitors do not support "variable" overdrive, which causes the issue you are describing when using VRR. All genuine G-SYNC monitors contain an actual hardware module that performs variable overdrive adjustments during VRR operation to prevent this issue.

As for the new "G-SYNC on FreeSync" driver feature for Nvidia GPU VRR use on FreeSync monitors, there is almost a zero chance Nvidia will ever add variable overdrive support, as it's extremely difficult to accomplish solely with software, a reason why 99% of even FreeSync 2 monitors paired with AMD GPUs don't have it either.

For LCD-based displays, variable overdrive is one of the biggest (and most overlooked) advantages of hardware-based G-SYNC over software/cable-based FreeSync.
