I have a LG wallpaper TV 65" from 2021. I see no burn-in whatsoever. Once in a while it says "we will do the pixel refresher thing when you turn off the TV". I'm pretty sure there's something to it but I'm no expert. Five years later and my TV is just fine.

A TV displays constantly changing images. A monitor displays items that can stay fixed in place a long time, hours or even days. Not the same at all.

I use it as a monitor as well. I think the key here is what LG calls "screen shift" which makes obvious sense. No magic, just move the pixels around to prevent stuff like HUD and logos from burning the screen.

Personal plan, but yes, my day job is being a security engineer for big tech.

Whats your thoughts on this being a temporary phenom, that will last until big corp applies AI's to resist this? Reading your article I get the feeling that the only security measures that you ran up against were just the obscurity defeated by disassembly. Plenty of posts here going "enjoy it while it lasts" but since you are actually working in the security field I'm curious about what you think of bigcorp pushback…

I suspect the bar will raise for some devices, but most will continue to be made cheaply and with poorly-defined requirements and threat models, and "it works" will continue be the only bar they're measured against before release.

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 hen…

OLEDS have two HUGE advantages over LCDs Extremely accurate and vivid colors due to their low black level. And VERY fast pixel response times, 0.01ms to 0.03ms compared to 1ms to 5ms for the fastest LCD gaming monitors.

Yeah OLEDs are the first display tech we've had that is on par or better than CRTs in all aspects. On balance the tradeoffs were definitely worth it for the various LCD panel options but motion clarity, colour intensity and black levels were all still beaten by a CRT in a dark room until we got OLEDs.

I'm hopeful that in the future we can end planned obsolescence from devices that require companion apps which eventually get shut down. Just vibe reverse engineering replacements.

There was a video on YouTube about a girl basically did this built her own replacements software for these kinda of devices, didn't use ai though

OLED burn in is not "planned obsolescence" any more than the "self-emptying gas tank". That's pure ignorance.

OLEDs burn in because of simple physics. The same reason your car's gas tank empties when you use it instead of some secret cabal stealing your gas to make you buy more. Ignorant nonsense.

Don't get your hopes up. What you're saying only applies to what is out there right now. New stuff will eventually just be locked down more. It's of course still huge to be able to do this with all tech up until this cut-off point. Eventually though, LLMs will have to break SOTA cryptography to keep doing this, and if they should ever manage to do that, there will be a rough awakening for the world that runs on that…

lol - if hackers hacking devices encouraged device vendors to secure their shit, we wouldn't be in this mess.

Indeed. Most of the barrier is the sheer breadth of devices on the market meaning nobody knows anything about your specific one. This is solved when you can automate it, no matter how bad the automation is as long as it works.

It's not "simple" physics. Or can you explain the physics?

Every display technology tries to suffer burn in if there's any long-term physical change at all from lighting up a pixel, because it will affect the ones that are lit up more often. That part is simple. However we did get around it with every other technology so please explain why it's not even theoretically preventable with OLED.

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 du…

What's the chance he would then get mad in a week when his monitor has visible burn-in, and try to return it?

While it’s impressive work from the LLM and a TS implementation is novel, there’s at least a couple of pre-existing Python REs eg. https://github.com/jya-dev/supernote-tool :)

It seems like most of these "an LLM solved this in only X hours! " could have been "I found an open source solution that did what I needed with X minutes of web search." Which doesn't mean that the LLM definitely couldn't have accomplished it without the prior art (in either the training set or explicitly in a a web search). But it does seem to be a trend.

Someone has to write it though.

LLMs make low-quality output in high volumes, and sometimes we find a situation where that's actually good - like this one!
