True story. I grew in the CRT era and for me strobing is a natural experience, so i leave it on full time.

A new interesting thing to try with newer Nvidia gsync enabled drivers and a subject Freesync monitor.

viewtopic.php?f=2&t=5000

I'm on kinda old 385.69 driver. If maybe someone can find the difference between gsync-enabled exact resolution and "normal" resolution, it may improve something like on AW2518FH. It may be possible to recreate non-freesync resolution with freesync exact timings, if it's any better like on Alienware. Worth trying imho.

one final issue on this monitor is that it doesn't enter into sleep mode. I turn off computer, but the monitor stays on. the osd says "entering sleepmode shortly" or something like that, but it never does. Hours later, it is still turned on (with the computer off). I have to manually turn it off, and everytime i turn on the computer, turn it on. wtf.. any tips? im using displayport.

edit: happened again this morning - forgot to manually turn it off, this morning the monitor was On, with the OSD message "preparing to sleep".... :(

i forgot to say this didn't happen with my previous monitor, same computer, i haven't reinstalled windows.

EDIT2: Doesn't happen anymore. I once had to disconnect the monitors from power outlet, and ever since I turned it on again, never happened again.

Hmmm, mine goes asleep fine, it shows "no signal detected, preparing to sleep" and then actually goes asleep with no issues.

I'm using "gsync" with my LG 27GK750F-b.
Runs great, OSD menu even shows the actual refresh rate in real time.

In Forza Horizon 4 it will double or tripple the refresh rate of the actualy frames.
So at 80 FPS it is showing 160 Hz in the Menu.

Works great. Also i resolved the issue with the "lag" or "frameskipping" / "stutter" or how you wanna call it.

For some reason my music player (Tidal) was the issue, no fucking idea why it does that tho.

Hi there. Ok, a lot has been written here, for me as a beginner there is a lot of incomprehensible. I have simple questions for the owners of this monitor. And yes, it’s not very correct to ask such questions, but I still ask - are you satisfied with this monitor? Are you ready to recommend this monitor for purchase? There are not so many 240hz monitors on the market. In your opinion, where is this monitor in the overall rating?
Understand me correctly, I do not ask for reasonable, technically detailed answers. I am interested in your subjective opinion.

I owned this monitor, along with many others (see my signature) and I didn't like how moving images looked on it... other monitors like the XL2740, XL2540 and AW2518HF were noticeably better in my opinion...
and not only that, they also felt more responsive.

A couple of people like this monitor here, saying it's good value (I could have gotten it for just 200eur new as well), but I'm inclined to say it's not...as I wouldn't be hitting shots on it, which I would otherwise do.
If for someone, this is the first 240hz monitor they try, they will be impressed...but that's the merit of 240hz itself, not this monitor.

Anyone found a way to get rid of the "Out of range" message? I can set it to 267Hz without playing around with CRU.

I have to say I ended up returning this monitor because it had a very noticeable frame-skipping bug. I tried the custom res fix but it would still randomly get the bug when I would restart the pc.

I now have the Alienware 25" 240hz which is just as good if not better (I don't use ULMB) and without the frame-skipping.

TFTCentral tested other LG newer monitor.
And it has a firmware update through the OnScreen control software and its input lag results are way better with new firmware. Gonna check if 27GK750F-B may receive the same kind of an update http://www.tftcentral.co.uk/reviews/lg_ ... m#firmware
Maybe they finally will fix that stuttering/frameskipping issue it has at defaults.

In short: no
I can even run it at 280Hz but Out of range always pops on, no matter what. Also it looks like it frameskips at 241Hz and higher.
