so how this monitor compare to pg248q? since i very sensitive to input lag and my pg248q hes amazing input lag

Ok, I am not sure now if 1ms BR works properly on my LG. Other than color palette changes I don't see much difference in blur reduction with a naked eye when turning on and off.
I did eyetracking UFO test and took images with my phone and 1/250 shutter and results look awfully close. I have made like 5 shots each and this is the worst OFF and the best ON
OFF


ON

This particular test pattern is bad to diagnose MBR problems, better use https://testufo.com/crosstalk
Well, first pic (mbr off) has much visible blur on bottom UFO. Look closely, UFO is blurred, and bottom UFO on second pic is much clearer.
Refer to https://www.blurbusters.com/faq/motion-blur-reduction/ to see how blur reduction should look in action.
Also you may simply shake your hand between your eyes and screen, with strobing on you will easily see a stroboscopic effect.

And what about jerkiness you mentioned? Did my fix helped?

There is TFTCentral review on that http://www.tftcentral.co.uk/reviews/lg_27gk750f.htm
The only thing is that they measured its input lag in 1:1 mode when Original mode is the fastest one, its faster by a full frame (4,17ms at 240hz) then 1:1 mode. So actually monitor is on par or better then other 240hz models in terms of input lag.

Yes, low latency VSYNC works fine. I went back to using IPS 144Hz though as I couldn't track targets at all and didn't get any better over 15 hours. After spending some time trying to understand why, I believe, its due to losing the crosshair/target co-positioning when shooting continuously due to nozzle flash (e.g. Tracer, Soldier). It just feels like I am blinded for short bursts of time. Snipers and single shots heroes were fine.

I'll make this as fast and painless as possible:
I too, have tried the LG 27GK750F-B and was disappointed with how responsive it felt, how clear motion was on it and how well I could actually play using it. I could perform better even on my old 144hz BenQ XL2411Z.
BUT don't write off 240hz as useless because of this.
Luckily, I've also tried the Dell AW2518HF before the LG so I knew how good 240hz can be if done right.
The only reason I got the LG was because I wanted a larger 27" screen. (The Dell is only 24.5")
After all this I went on to try the XL2740... and it was competitive gaming monitor Nirvana.
So, before giving up on 240hz, try either the aw2518Hf or XL2740, I'll guarantee you, It'll be a much different experience than it was with the LG. (Which is a failure of a monitor in my eyes.)

You describe it meaning you were playing with MBR on? You may be not used to strobing, many people feel strobed modes weird and dont like them. But some, like me, are used to strobing - I was on full time strobing-on monitor since 2013.
Perhaps you need more time to get used to strobing. Whats your average per-day online time? 15hrs in 3 days, and 15hrs in 3 weeks are different, you know
Im also a tracer/soldier/zarya main, and feel it tracks perfectly. This "connected feel" is even better after I switched to "Original" scaling mode. Even though i'm practicing hanzo and mcree flicks, the more I track the better it becomes.

Original scaling mode?

Like in the Nvidia drivers?

Yes, it's with MBR ON. I tried tracking without shooting and it felt fine though. This is why I attributed it to nozzle flash. I switched to "Original" scaling mode the very first minute after reading this topic.
I had spent 15 hours over 4 days.
