Okay. Got the sync track to line up with better camera work @ correct shutter speed. Results are similar though. Tried a little comparison with and without strobing.

Nice result! If you plan on doing more of these comparisons in the future, could you maybe try them at a faster speed like 1920 px/sec? I’d love to see some comparisons between strobing on and off and overdrive on extreme and normal at that speed. My camera sucks and isn’t good for this.

Great result indeed! Good thing you did all 3 ufo tracks/shades. Is this a photo or video? If photo can you share the originals, uncropped.

Note if you're comparing this to 360Hz that 360 is actually panning at 1080pps and 390Hz at 780pps. So its not very smart to compare the two directly.

I hope you do the fullscreen strobe crosstalk pursuit.

Didn't you buy the monitor and tried all this?

Bijan's does it at 1920pps, here: https://youtu.be/O_ddND-QiTA

Thanks. Here are the results with this super fast 1920px/sec ufo. These are pretty hard to catch well, and extreme overdrive really adds only a strange white overshoot corona around the ufo so I would not suggest using it.

I also included the original photos here.

Yeah, but to my own eyes I really wasn't seeing a huge difference with BFI enabled or disabled. These pictures show that it definitely does help, but as we talked about before, I don't think it makes a huge difference on this monitor.

Awesome! Thank you! I still can't decide if I prefer VBR on or off. In some games it seems to be beneficial, but in other game it's unnoticeable for me.

Switching back and forth between normal and extreme, I really wasn't noticing any differences. I'll have to try again later today. I was playing on extreme because I figured if I did not notice any inverse ghosting then extreme was likely still faster.

Well. Decided to try it anyway since I'm playing around here. OD: Extreme is by no means unusable setting as per usual, but it does introduce some white trailing artifact behind movement here still without any clear visual benefit. Possibly a bit faster but I would rather live without that messy look on objects. Would be so interested to actually see rtings or hardware unboxed to review this.

I will try my best to more comprehensive fullscreen strobe crosstalk pursuit some day now.

Now some Z's.

Awesome work! This is a great resource for people looking to buy the monitor and compare the settings. I too am very interested to see RTINGs and Hardware Unboxed reviews, mostly because the results can be directly compared to so many other monitors they have used the same testing methodology with.

well you guys can continue to mostly ignore me but I can tell you (trying to help as usual) that what I've seen you guys go on and on about and the laborious results you guys may or may not have finally arrive to, has all been covered long ago (8 months ago) in my vids. I don't get why any one of you STILL need to wait for any "official kol" posting ANYTHING, just enjoy it.

That's how the monitor is. As some of you also said, it's not perfect. But I told you guys long ago to max both and forget it, it's a clear and no brainer improvement, it's why the feature is there.

I am playing exclusively with this monitor now, but i am interested in sharing my findings and seeing what others are saying about it. I am not trying to ignore you, but sometimes the way you type has me confused as to what you are trying to say. I'm not trying to be rude. I am just trying to make sure I understand you correctly.

So you're saying to max both the overdrive and backlight strobing to extreme? In another post, you recommended brightness and contrast both on 8. Wouldn't that be far too dim?

Was just talking about in general. Those vids aren't in english and I don't feel like doing them all over in english again. But still.

no. extreme already is brighter than 8 and 8 and off. u start from 8 and 8 that's your productivity/browsing brightness. also gamma is set to 2.6, lowest brightness. in the day time for browsing you need to up it to 2.2, for none hdr movies 2.0 or 1.8.

for gaming at night, extreme is actually too bright and causes fatigue, not to mention this not being a perfect monitor and those obvious trails (that is to say, the main image is more sharp but the blurry ones u could guess it but didn't have distinct ghost--but in game the ufo tests are obviously not equivalent, actually the bigger the hitbox the less relevant obviously..in fact ufo test is in itself very extreme, because there isn't much game out there that have insane speed AND small hitbox, apart from flying jets, which brings back to WT again, maybe it means a lot more to the russians and euro people playing in low ping servers and in tournaments, in arcade mode--even then dogfighting in close quarter or a close flyby is still gonna be a lot faster target image on screen, while the hitbox inevitably become bigger than in distance), best to watch movies and chill at night time or just go to bed.

This I have come to feel at home with. I don't know why you would instead want brighter in productivity where there's usually white spaces all over, and then have a dimmer experience in gaming. For the 180hz ROG I can't be bothered to recall if it was not much brighter for gaming, if so, that just meant I had to game at night +turn off lights more.

I don't know about premium TV or mobile screens, nor do I need to I feel. They are not relevant for the context of hardcore gaming, and this being an "ips" and "hdr 400 capable" has shown me that there is no real different from a TN. For a gamer, the only eye hurting thing is low hz. You can still have the liberty to feel that with a high hz monitor, just play in badly optimized gamespace, play with ultra high ping and/or bad internet routes, play all max graphics. For me, I set my colors to a yellow green hue too and I don't need to share that cus it's even more preference and someone will start to disagree for no reason again. In fact with this monitor I don't think I have set any colors and really ain't bothered to check again. I certainly have max blue filter as always (which also dims brightness but that's duh), it's not like I'm missing out on anything, HDR movies are always there. Like that's your so called "normal", it's just a brief thing, my eyes will hurt if I use that max brightness all the time, with 4k media and potplayer obviously there's too much information per frame compared to all low gaming. So yeah, it pretty much HAS to be high fps low rez low brightness, or low fps high rez high brightness, for now.
