My 27" FT45 monitor (LF27T450FQNXGO) goes into sleep mode and wakes up when it's supposed to. But while in sleep mode it will repeatedly turn on for a few seconds and back off. Continuously and regularly maybe every 10 seconds. What's on the screen is just what it was when it went to sleep; nothing changes there.
What's turning it back on? I've been turning the power off to make it stop at night or it will do this all night.
You're awesome! Sticking with this, tracking down the issue, and contacting Samsung is impressive and I'm grateful. It's interesting that this isn't that uncommon.
I've given up on turning the monitors off overnight because everything on the desktop moves to one monitor or the other when I turn them back on. So, at least for now, I'm just letting it go on and off all night. It's not near the bedroom so it's not that bad though there was someone else who popped into the thread a while back saying he had the same problem and it was a problem at night.
So now we'll see how Samsung responds.
I believe the Intel graphics utility updated the graphics card driver but I'll do it manually to be sure. I do prefer that anyway since I know what was actually done. I didn't update the chipset software but I'll do that.
I'll check the website for the Samsung ICC profile. I haven't done that before but I'll figure it out.
I have the same problem with my Samsung M5 monitor. Except that this happens even when my laptop is switched off. It says that it goes into standby mode then 10 secs later it wakes and repeats that it's going into standby mode in one minute.
I don't want to manually turn off my monitor cos I means I have to switch it on and off everytime I want to use it.
Same here. I was turning my monitors off every night but then it started moving all the windows to one monitor when I'd turn them on and I'd have to rearrange them.
I just ran some diagnostics and utilities to see if cleaning things up might help and it found some things. I'll do some more tests in the morning.
No problem! I don't have any other path, and I'll deal with it in the meantime. I'm also thinking the MB has an issue as I'm seeing behavior change with regard to this and some other things like not sleeping when it's supposed to. This is an old MB and there's a UEFI update but I haven't been able to download it. I'll contact the manufacturer (ASRock) for help there and report in if I learn anything there.
