black frame insertion

[Falconbruh]

Hi, 

does bfi half the refresh rate since it inserts a black frame or did i get that wrong?

Also, is it noticeable at 144hz or 240hz? Are pro players using it or is it better to have a good panel with very little blur instead?

Does it make sense to get 240hz to eliminate flickering (if it does help)?

Thanks in advance

"Black frame insertion" usually refers to backlight strobing. When you use backlight strobing it does not change the image on the panel to black, it just disables the illumination on the monitor briefly. It isn't subject to the refresh rate limitations of the panel so it can flicker on-off once (or multiple times) every frame without issue. It doesn't affect the refresh rate of the monitor.
