As far as I know is that, monitors with a G-Sync module are further optimized in overdrive and in colors.
I’m not sure if its the G-Sync module that does the tweaking or if its the monitor itself that is already tweaked.
First of all, the presence of a g-sync module when activating vrr uses a dynamic overdrive, unlike monitors without a g-sync module. I will not be able to answer all these questions correctly. I have only assumptions. I think you should ask these questions to Chief Blur Buster.
Hope he sees this message, otherwise will start a new Topic about it.
Thanks again for helping me with this.

The G-Sync module was a replacement for the whole PCB of the display initially. Not sure if that changed at some point. But I'm pretty sure that even if the gsync module only replaces parts of the PCB nowadays and doesn't completely take over everything, it is still fully responsible for overdrive, regardless of whether gsync is currently active or not. Obviously when gsync is currently active, the overdrive algorithm is changed in order to handle variable refresh. If gsync is not active, the optimal overdrive algorithm is used for fixed refresh. If gsync is active, the optimal overdrive is used for variable refresh.

(As a side note, I can't believe how it is possible that there's no footage of a modern gsync display being opened up and examined. One would expect that with the amount of youtubers and hardware sites out there somebody would have done it, like they do with virtually every other hardware. But nope, there seems to be nothing. Nobody is curious? Really? They throw a $1000 phone in a blender but non-destructively looking at the innards of a gsync display is a taboo?)

My guess was: all g-sync monitors are nvidia monitors on which they were allowed to glue the vendor label. Like the founders edition video cards, with asus msi stickers, etc.

Yes, the contrast ratio range reduction can reduce the ghosting part. Ignoring the focus differences, and focussing on the coronas/trailing artifact, that is an expected behavior. That depends on how the monitor processes contrast (digitally decreasing white level, increasing black level, to provide overdrive headroom below black, and overdrive headroom above white. Doing this produces fewer coronas and reduced strobe crosstalk).

It is a sort of a pick-your-poison: Do you prefer contrasty colors, or do you prefer eliminating coronas? (But at least that's a user choice)
For those who want to experiment, spend their time and sacrifice contrast.
I propose a method that I used before buying a high-speed camera.
Those who do not want to lose contrast, are looking for perfect settings, asks the question: "which is better? What is worse? What do you recommend?" - Just close this topic, do not waste your time.
Another 240Hz xn253qx monitor fell into my hands. Stock settings r50 g50 b50, contrast 50, overdrive normal. the range of colors is 0-100, the range of contrast is 0-100.
On the stock settings in the test https://www.testufo.com/ghosting#backgr ... &pursuit=1 I see ghosts that do not suit me.
For the method that I suggest, we need a test https://www.testufo.com/chase#backgroun ... &height=-1 .
I adjust each color separately. In the monitor settings, I set r0 g0 b50. I change the viewing angle as shown in the video until the image is shaded. https://youtu.be/e3ofKI2-HTs
Slowly lowering b50 and continuously watching how the ghost changes. At a value of b43, the ghost is very similar to a firework, it seems that the pixels sparkle, at a value of b42, the firework disappears.
I will call it a ghost firework.
The same goes for red and green. I get r35 g38 b42.
In my version of the monitor (r35 g38 b42) contrast 50). For values ​​(r50 g50 b50) not higher than contrast 35. If the method is clear, you can easily translate the rgb values ​​that are pleasing to your eye while maintaining the highest possible contrast.
You decide when to stop!

Recording in one take, but fast).
Stock monitor settings, only the contrast of 50-25 changes.
Speed ​​is 3840.
