If there are any parts that are unclear or grammatical errors, please let me know in the comments section. I currently use a Dell U2720QM monitor, which occasionally experiences screen flickering (3 times in 4 years). I previously thought it was due to unstable voltage or poor connection, which usually resolved after powering off for a while and restarting. However, last night multiple restarts didn’t fix the issue. After some research, I found that screen flickering seems to be a common issue with Apple M series chips, especially M1 and M2, and BenQ monitors also experience this problem. There are various proposed solutions, each with their own reasoning: None of these methods worked for my situation. Finally, activating LCD Conditioning in the monitor’s hardware settings resolved the flickering issue. Additionally, some users mentioned that the open-source software aiaf/Stillcolor can permanently fix this issue by disabling Temporal Dithering. I’ve installed it as a precaution.
