I specially registered to say that my monitor LG 27GK750F-B also died... I bought it in April 2018 and now, after 3 years, it only shows a white screen... Now I don’t know what to do. For me, this is an expensive monitor and I can’t just throw it away, for sure someone has come across a repair that is not under warranty, how much did it cost you? And what was the renovation? I gave it to one workshop and there for several days they have not been able to identify the cause and fix it, tomorrow I will go to pick it up... And then, apparently, I will have to take it to the official service center, but the repair there will probably be very expensive and time-consuming...

Hey I'm running the CRU OC from this thread to reduce stutter and recently the blackscreening has gotten way more frequent (like 10+ times per day sometimes) even when I don't touch the OSD. Power cycling doesn't seem to reset the time until next blackscreen like other users suggested but maybe I'm not doing that step right? Any suggestions or should I just deal with the stutter and reset to default settings?

try increasing the front porch to 59, or reducing to 55

So I've managed to download the service manual for this monitor.
and in the service manual there's a section in which detailed resolutions are described. They are a little different from the ones described on this thread, but they work VERY well.

I suggest everyone to give it a try. Export you current CRU settings just to be safe. Here is a screenshot of the settings:

I asked Simon from TFTCental and he answered me that they tested both 1:1 and default Full wide mode and it made no difference.

But it is known that lowest input lag is in Original mode (see first post). I've informed Simon when it was found, but they did not retest the monitor so initially measured values are still in review.
Any response on this matter? In 2024, I still have this monitor, thanks to you I was able to improve it, but I feel a significant input lag compared to other monitors I've played on.

Have you tried the service manual settings I've posted a couple of posts ago? For me it works best. And AFAIK there's no OC, as the VT is 1215 while its very close to 239.760hz.
