Google AI says a 240HZ Monitor will display 60 FPS contnet with 75% less persistant blur

Is this true?
It says 240HZ OLED has a massive benefit 75% reduction on persistent blur almost making it like backlight strobing when dealing with 60 FPS games
I had a 240HZ monitor IPS and 60 FPS content made no difference whether I set it to 60hz or 240 HZ

No, that will only happen if you have maximum full-frame-based BFI at 240Hz, e.g. 60fps at 240Hz using 1 visible frame for every 3 black frames.
60fps sample and hold has the same motion blur at 60, 120, 240, 480Hz (assuming GtG is the same).

But 1200HZ you said will allow 60 FPS to have almost no blur right?

Only with BFI included. To understand better,
TestUFO Demo of Variable Persistence Black Frame Insertion for 240Hz Displays. Your maximum blur reduction will be the ratio of InputHz:OutputHz. (Adjust specifically for your display, you have more BFI flexibility at larger ratios)
Without BFI, and on a sample and hold display, 60fps 0ms-GtG has the same blur at 60Hz, 120Hz, 240Hz, and so on....

^ WOW I saw it in the link you sent me that's Amazing I saw a 55 FPS with 2 black intervals and it looked like it could literally be 1000HZ at 1000 FPS
Absolutely insane. So I guess strobing / BFI is absolutely essential regardless of whatever HZ we reach.
But that was super cool to see BFI on my 165HZ monitor actually run 55 FPS content like that without having to drop any HZ to match FPS

What about 30 FPS on a 120Hz BFI? Will it look significantly better? And what about duplicate images? Or is that only on impulse screens?

Yes, you will get duplicate images.
BFI=impulse
It is a personal preference if you prefer more motion blur or duplicate images, and how many. 30fps at 60Hz flicker of any kind is two duplicates, and 30fps at 120H flicker of any kind is four duplicates. Pros of 120Hz is less flicker than 60Hz, but more duplicate images.

I find it weird that I never noticed duplicate images on my plasma while playing 30 FPS games at 60Hz -- marketed at 600Hz. I also never noticed flicker. Damn, I wish I kept my plasma so I could compare it...

It's only noticed if you track your eyes on framerate=Hz motion, e.g. panning motions like
www.testufo.com or
www.testufo.com/photo
Duplicate images do not appear if you keep eyes stationary (E.g. crosshairs).
Displays behave different whether your eyes are stationary or moving.

Here's a TestUFO software version of double image effect:
www.testufo.com/blackframes#multistrobe=2&pps=1440 (use faster speeds if your Hz is higher)

Thanks for the reply. The thing is, I never really noticed it. Playing 30fps games on my plasma always looked really good, especially in motion. I never had the awful stutter that I have with an OLED.
By the way, I did see a kind of "ghost" image behind characters or objects with a still picture, but only when looking very closely at an angle. I suspect it's because of the glass cover plasmas had.
