Okay friends, let’s check who has a Samsung OLED panel, and who has the BOE OLED panel inside his Deck.
Steps to check:
-
Go to Desktop mode
-
Open Konsole
-
Paste the following command into the terminal:
cat /sys/class/drm/card0-eDP-1/edid | hexdump -C
You will get the output like in this screenshot:
The marked number is relevant and means the following:
01: 800x1280 @59.998545 (BOE, LCD)
02: No longer present
03: 800x1280 @90.003892 (Samsung, OLED)
04: 800x1280 @90.061454 (BOE, OLED)
So my results are:
Model: Steam Deck 512GB OLED
Panel: Samsung OLED
What’s yours? Please also don’t forget to post the model, so we can analyze if there’s some correlation.
I don’t get it. Why would you even do this? If it’s not perceptible without slomo why would you even care?
Flickering (for some) can cause headaches and other issues like eye fatigue (even non visible).
This is a well know fact that anyone who’s sat under flourecent lights for a prologed period of time can attest to.

Some people are susceptible to certain frequencies of PWM dimming, even if there’s no perceptible flicker effect. For these individuals it can cause headaches and eye strain.
There are frequencies past which practically nobody experience adverse effects from usage, but it’s a pretty high number and a lot of PWM screens (not just OLED panels) fall well below it, especially at brightness levels below maximum.
