@haeckerfelix wait, what? 😳😅
I have the same issue! With a different chair, not from IKEA and only my main screen (the secondary one is identical though) shuts off randomly sometimes. Thought my GPU was bad or something, never could've thought it might be linked to the chair. 😅
@amxmln Is it possible that your second monitor is connected via DisplayPort?
I have the feeling that DisplayPort is more "sensitive" than HDMI in that regard.
