> My ASUS ROG Swift PG42UQ monitor was actually where I started, because I got annoyed at the pop-up overlay that comes up every once in a while that tells me to run “pixel cleaning”. I have never intentionally run pixel cleaning on this monitor and I never will, I don’t care, and I would like for that overlay to go away forever. Maybe there’s a debug menu or something that can turn it off, or worst case we patch a branch in the firmware?

Note that this is an OLED monitor, so the "pixel cleaning" thing is probably some sort of anti-burn in feature. You could probably ask the AI to look at the firmware and describe what it does.

Yeah, you actually want to do this with monitors of that generation to make them last.

You could argue that there should be an option to disable it for people who don’t care.

Refusing to take 1 minute out of your day to learn the reason for the alert is a strange self-defeating protest next to the explanation that it was a pretty expensive monitor.

The Internet seems rather reluctant to explain what exactly "pixel cleaning" does, but based on the vague useless "explanations" I could find, I suspect it's a sort of "flat-field correction" where it calibrates the pixel drive current to darken the less worn and/or brighten the more worn ones so it eliminates the burn-in effect. This obviously leads to a vicious cycle where more worn pixels are driven harder and hence wear faster...

IMHO OLED is a planned-obsolescence dead-end anyway; LCDs can last literally decades, maybe with a backlight replacement, but OLEDs are designed to fail in a few years. I have a few (rather expensive) pieces of test equipment with OLEDs that became unreadable after only a few years and had to be replaced (fortunately with a regular LCD, and some firmware patching), while others with old-school CSTN/TN LCDs are still fine.

I don't think learning more about what it does is going to make them change their mind here.

Or ask for a patch so it runs after the monitor has been powered off for a while...

I use an LG OLED 42inch TV as a monitor and it has a setting to do just this.

I have an ASUS PG32UCDM and an ASUS XG27UCDMG, and both can permanently disable the "pixel cleaning reminder." Have you tried update firmware and look in the monitor UI?

That's exactly what it is, and it's pretty important to run

Or update the firmware to do it every n hours or screen blanks or something automatic with no nag

Every 8 hours is insane, though

That is just crap UX. Sonys OLED tv-s for example do this automatically while in standby mode in addition to pixel shift while displaying an image. On the other hand Phillips OLED tv-s also ask the user if they want to do a panel refresh.

Perhaps you didn't read the text you just copied and pasted, but here it is for you:

"I have never intentionally run pixel cleaning on this monitor and I never will, I don’t care, and I would like for that overlay to go away forever."

No need for ackshually, the guy is clear with what he desires. That is, by the way, the point of TFA. I want my devices to do what I want, not what a product manager wants or what a dude on hacker news wants.

The author even dropped a comment here doubling down on his intent. That is the main problem, when the smaht guys think they know better, to a pathological extent where they tell other people what they ought to do with their things .
