HiDPI scaling really isn't so good on linux. Elementary OS allows lowdpi which really isn't low dpi but allows native scaling. It also has HiDPI, which is 2x scaling. For me 2x scaling is atrocious. Low scaling is too small. On Windows I use 150% scaling. I could get by on 125% as well; but pure 100 is to small.No harm: Flicker Frequency * 0.0333. Low-risk: Flicker Frequency * 0.08.
