Strange...
Here is the answer I got from TFTCentral about it:

Hi

Thanks for the email. We tested the full wide mode, and 1:1 Mapping mode and both showed similar results. The figures in the review are based on measurements in the 1:1 mode.

Thanks
Simon


Said nothing about Original, and speaking of "both" out of 3 modes present.

@captain_amn
I would say, non strobed, 240hz is probably best monitor at the moment. Dunno about new Benqs, but they a lot more expensive.
Non strobed 120/144Hz sucks, for me, as they are blurry as hell for me(same with Benq)

Strobed...I'd say, strobed 120Hz, VT tweak 1499, my old Benq is little better(but only in middle) in clarity, while running ufo tests(moving photo -ufos, quebec or Eiffel tower, street map), LG 240Hz has less clarity, due ghosting, or, I would say, tripple images. Text in street map is more fuzzy, smeared, on LG than on Benq. IN MIDDLE, but, well, if u play games, in middle is where ur focus is. As for me, in games, I barely see difference. I mean, playing 240Hz strobed/non strobed is great, have good results, that yesterday went from high 5-7k/d ratio to 1-2 only, due my fatigue...was playing/testing like 8h with some small breaks...So Id say, I have similar results, so, blurrines/smearing is not noticable in game as much as in ufo tests. Did VT trick too here, but seems to do nothing to size of crosstalk or maybe I looking wrong direction :P
Big pro is brightness, is more bright and colours more natural looking than my Benq 2720z, even after my so so DIY callibration.
Default sharpness suck, 50 makes things blurry, even my son when looked at screen for 5 secs noticed it right away, and he is using Samsung 27" CFG73 with Qdot Led and this crap is blurry with text as hell. But he like it for Rainbow Six Siege/Daying light/CS:GO and have good results too, so...maybe it is youth...


So for me, it is (rather) good monitor, but have mixed feelings. Esp with that dust/whatever just under LCD layer. At least it is not a bug...so is small, 1,5px size...I will test it more though, have 30 days to return it. Maybe in this time freaking JOLED finally start selling Oled gamers monitors... Maybe I will keep, maybe not. So far, mixed feelings...

lill edit, missed proper name

I guess I fixed it for you :P Trust me, I had several 240hz from the first gen, Asus XG248Q completly outshines those first panels. Native 240hz, very fast panel and being 24 1080p is a plus too.

Maybe, I was referring to size mostly as I use 27 only.
Was thinking about buying 24 Benq BenQ ZOWIE XL2546 but damn me, pay more for less inches, and I'm getting older, so smaller screen, more eye strain...nope, nope.

The Asus monitor is an option too, but i also care a lot about the strobing! Since i never tried it, i'd like to have one with excellent strobing, dunno about the ELMB by ASUS.

@Gregix Thanks for the reply... looks like it's not so bad after all, despite what Solid Lad says.

The strobing disorients me in games; well I should say the crosstalk makes things look really weird, that's what seems to be disorienting (LG monitor). It's basically half effective at what it's supposed to do, I think at least in part due to the crosstalk (I never did get the crosstalk to change at all, been lazy/busy.) I really like having that motion clarity, so it's a bit of a shame.

I wish the LG could do 60hz strobing, or something similar to BFI. I wish the timings were tighter and the response times more in line for 144hz and 240hz. I wish it were the most beautiful panel on the planet, too, and at least 1440p. I personally don't care about the size.

I really want to see those JOLED displays. I wonder if they'll reduce motion blur or have rolling scan, etc.

How good is this monitor now compared to his much praised XL2740, that i certainly won't buy?

I could get the Alienware 240Hz FreeSync (which Solid Lad praises) for much cheaper, but it lacks strobing. So i'd rather have the LG one honestly, because i play a game that could benefit from strobing and most importantly, a very responsive monitor. I really want to upgrade, but now i am so uncertain.... so..

1) To the owners and testers of this monitor: Is it really not an amazing monitor?

2) My follow-up question to the owners of this monitor is also, that i like playing with black bars on the side, because i play with lower ingame resolutions than 1080p. Is that still possible with "Original Aspect Ratio"?

3) To the more experienced testers here: What do you recommend? I can not compare the monitor vs other 240Hz models. So if i order it, i really want to just keep it honestly. So i would be glad, if this particular monitor is a atleast on par with other 240Hz strobing monitors.

Thank you for everyone else for this massive thread, it helps me a lot on deciding how to spend my money. (Monitor manufacturers take note :D )


The response times are subpar compared to better quality panels, and for 240hz they seem kinda slow. The colors don't seem bad. Also I should mention 1440p is liked by a lot of people, and the LG obviously can't run 1440p. I have one of the later versions, 3.07 (perhaps the latest version) and I've had no success with getting CRU (custom resolution utility) to reduce the crosstalk at all. There's a chance it looks fine and I'm just a unique case or picky. I'm not sure there are any other 240hz strobing monitors - this might be the only one, was the last time i checked. Keep in mind this monitor only runs strobing at 120hz, 144hz, and 240hz. There's not even a 180hz option, IIRC. If you play a game that runs at 60fps or was designed to run only at 60fps, the strobing will not help (because the LG can't strobe at 60hz, you need stroberate = hz = fps) and will probably make it look worse, duplicating images. I have one game that runs very high frames per second, but in reality doesn't display more than 60 frames per second.

I believe you can keep the monitor in original aspect mode, my tests indicate you can and stay in original aspect mode but I'm not sure you still benefit from the 1 frame reduction in lag. [I'm not sure if your resolution/game is going to stretch the pixels out or not. I think your resolution would have to "fit into" 1920x1080 and it should since it's smaller, but i'm not clear on the details. (if this isn't correct someone please tell me.) I'm mostly speculating so take it with a grain of salt and hope someone else answers. If the monitor changes resolution based on the game's resolution, I'm probably wrong. The tftcentral review said the interpolation for other resolutions looked fine, though.]

A Solid Lad seems to know some stuff. Maybe he'd respond to a PM; he doesn't have this monitor anymore though as I'm sure you read. Plenty of pro FPS players play without strobing. The LG monitor might be most effective in a game like Quake I guess. Since you have an rx 580 you can at least use Freesync if you don't like strobing or can't maintain the fps; you can't use Freesync and Motion Blur Reduction mode at the same time. And oh, the change from 24 inches to 27 inches could be quite the change for you.

And, I should add, no matter what Hz I use, 120 on benq or 240 here, LG, I do not have screen tearing.
Easy
Just using window "burdeless" :P mode. Not fullscreen.
So req Hz-FPS do not hit me, or, shuld say, do not feel it as necessary. Or maybe my perception is wicked and I do not feel negatives with lesser FPS than Hz, and I playing games that varies from 90 to 350FPS.
Definitely I do not need to use any Freesync/Vsync/G-sync by just using windowed mode...

You're talking about screen-tearing, not strobing, yes? Or are you talking about strobing but in windowed mode you don't notice negatives..

Thanks for the detailed reply Kheri.

I intend to use the monitor exclusively at 240Hz/ 240+ FPS and i am fine with 1080p resolution. Purely for "competitive" gaming (no freesync).

It seems like Solid Lad is very much against this monitor even though he didn't try the Original setting, so i was hoping for people to prove him wrong honestly. Well i am not that much smarter now that you mention that bad crosstalk :/ hmmm i really had my hopes high. I could get that Alienware one, but all this fuss about strobing... i just have to try it!

PS: There are quite some other strobing@240Hz monitors, not so sure what you meant there :P
