Desktop mode always has brightness at 100%

[Anactoraaron]

Hello! I have noticed that no matter what brightness I have set in gaming mode when I switch to desktop mode after a few moments the screen brightness goes to 100%. After investigating this I discovered that every time I switch to desktop mode the brightness slider is always at 100%. An easy fix is to just change the brightness the moment I enter desktop mode, but the solution is to have the brightness match the current brightness when entering desktop mode - these should be linked.

Exactly the same thing happens to me. I have the latest version.

It's more than just annoying. I had heard that OLED screens have a tendency to burn in if something's on the screen too long, so when someone got me a Deck for my birthday (a device that I love but is FAR too expensive and impractical for me to justify replacing if something were to happen to it) I looked into whether or not I should worry about the screen burning in.

My fears were assuaged at first when I read that Steam Deck screens are extremely unlikely to burn in unless you leave them on with the brightness set all the way up all the time, which seemed like something I'd be unlikely to do unless I was going out of my way to burn the screen on purpose.

So imagine my horror when I discovered that the brightness is automatically set all the way back to 100 whenever you switch to desktop mode, which is something I do quite often. Nowadays, I frequently experience little twinges of fear and guilt after realizing that the screen has been set all the way to 100 after dozens of minutes of watching YouTube videos in Desktop mode, and I'd really appreciate a permanent way to prevent these irritating realizations in the future.

it only matters if you leave the same image on screen for ages on full brightness. having changing content on screen is safe at any brightness.

Yes, and, as I said in the quoted post, watching YouTube in desktop mode while I get household chores done for an hour or so at a time tends to leave plenty of unchanging elements on the screen, hence my anxiety.

what kind of videos do you watch that have unchanging elements?

The videos don't have unchanging elements. Everything around the videos (the YouTube web page, the internet browser window, Steam OS's task bar) is unchanging.

well, fullscreen the video

I could fullscreen YouTube to prevent burn-in, yes. But remember that my problem is NOT that I don't have a way to prevent burn-in. I already have a way to prevent burn-in, which is to turn the brightness down.

My problem is that I don't have a PERMANENT way to prevent burn-in that doesn't depend on me remembering that I need to take preventative action every time I switch to desktop mode.

If I could trust myself to remember to enter fullscreen mode whenever I used YouTube, then I could just as well trust myself to remember to lower the screen brightness, rendering fullscreen mode unnecessary for the purposes of preventing burn in.

So, just as I don't trust myself to remember to lower the brightness every time I switch to desktop mode, I don't trust myself to remember to turn on fullscreen mode every time I watch a YouTube video. It's the same problem.

On the other hand, if Valve spent half an hour patching the Decks to keep Desktop Mode's brightness setting consistent with Game Mode's setting, the problem would be solved permanently for everyone.

Does adjusting the brightness by clicking the battery icon and using the brightness slider work?

It only temporarily works. The problem is that the brightness in Desktop Mode keeps getting reset to 100%.

I did some further testing on my Deck and discovered that switching to Desktop Mode from Game Mode is NOT what causes the brightness bar to be reset to 100%. What ACTUALLY seems to be causing the reset is shutting down or restarting the Deck. Doing this reliably resets the brightness value in Desktop Mode to 100%. Setting the brightness down to 30% and then switching to and from Game Mode does NOT reset the brightness to 100%.

I also discovered that when switching into Desktop Mode, it doesn't immediately set the screen's brightness to the displayed value by the brightness adjustment bar. Instead, it seems to take it about a minute or so to realize the screen's actual brightness is different from the value displayed in Desktop Mode's brightness adjustor and corrects itself.
