It really shouldn't matter as long as the frequency is high enough (>2000Hz). On their 1st gen laptop it seems seamless to the point where I can't tell (if it's DC or not).
Some Hackernews have slomovision and are sensitive to flickering even at frequencies high enough that you'd think it wouldn't matter.
Thanks for sharing. The high frequency doesn't seem to matter (example newer Macbooks). Unsure additional parameters like temporal dithering play a role.
