PG27AQDM Base LED doesn't turn on since MCM107

[markob53]

Hello,

I've already created a thread talking about my issues with MCM107 compared to MCM105 with very little feedback, but i wanted to create a separate thread highlighting a consistent issue which may be easier to replicate and may be connected to the issues i'm having in the hope we get a fix.

So now since MCM107 the base LED turns off when i turn my PC off (i like this behaviour) however when i turn my PC back on the LED (most of the time) doesn't turn on, when i say most of the time, what i mean is it might come back on after an initial reboot or boot up, but inevitably it will not come on after one or two boots then it will stay off until i turn the monitor on/off again, rinse and repeat.

This should be easy and obvious behaviour to replicate if you are using the stand the monitor comes with, so unless something is faulty with my monitor i assume a very quick test will confirm this behaviour, if it hasn't already been confirmed.

It appears that most people are now satisfied with the HDR colour accuracy, but there's just a few issues that the last two firmware's have introduced that did not exist on MCM105, highlighted here.

Can i at least get confirmation that Asus are working to fix these issues, or is it something wrong at my end that i can try?

Just a quick note on this issue, i mentioned the possible cause in another of my threads but didn't update it here.

It appears in my case the cause for the lights going off and staying off was related to the USB hub power setting, i had it set to turn off when in standby mode and it appears that the LED light is effected by this setting from MCM106 onwards.

I don't think having things attached to the monitor would make a difference either way, but if you have the above setting toggled to save power (so the things attached go off when not in use) then it would make sense why you are also seeing the issue and why most aren't (aside from the fact a lot of people use monitor arms).

It seems to still be a bug that needs fixing, even if you're quite content to keep power going to the USB hub.

I'm still on MCM105 myself due to other issues i've described, sent a PM with my info to one of the reps here, hopefully we get a fix soon.

EDIT: I've just noticed MCM108 has been posted, unfortunately i'm still at work so can't test if it fixes my issues (my specific issues aren't mentioned in the notes but maybe they're too specific) here's hoping it sorts all remaining issues for everyone.

It also mentions fixing of the RGB lighting after a pixel clean, maybe it wasn't related to the USB hub at all.

Just upgraded to MCM108 (thanks for the heads up 🙂 ). RGB behaviour is like it was in MCM105 (always on), so I am quite happy with this. 😄
