LG's firmwares are pretty bad in my experience. I have two LG monitors and they both have weird quirks.

On the first one (a 34" ultrawide), all of its inputs lose connection for a moment whenever it wakes from standby (including the USB ports, making them useless for external drives). This also has the effect of causing my computer to occasionally lock up on resume from hibernation unless I tap the power button on the monitor before I wake the system. Additionally, at refresh rates above 60Hz the gamma gets progressively lower making the image darker the higher you go, even though the gamma setting in its menu is exactly the same, and black frame insertion and game mode are both off. Others online have reported the same thing.

The other monitor I got second-hand and it mostly works. It has a horrid HDR implemenation however that just washes out everything. I also tried to use brightness and input control via DDC/CI, which is a fairly well known standard, but this causes it to shut off abruptly and I have to unplug the power cord it to get it back.

Wow you just off-handedly resolved an issue I’ve been dealing with for months on my Linux desktop. I lost an hour of Baldur’s Gate progress the other night after this happened after I hadn’t saved the game. Thank you!

Your fix also resolves a similar issue I have on the Mac side when using my work laptop. If I tap the keyboard to resume from sleep, my LG monitor wakes up but doesn’t display an image. I have to wait for it to go through the motions until it finally displays “no input” before tapping on my keyboard to make it display the lock screen. Meanwhile, my second monitor works from the get go.

I somehow never thought to hit the power button first. I wish there were a way to make the LG monitor work like my other one and not have to do that.

Awesome! Glad I could help.

Yeah unfortunately that would be on LG to release a firmware update. And from what I can tell, they'd rather you just buy the new revised model.
