You can manually adjust your display brightness through Control Center, but the HDR videos will still likely appear brighter than expected. This is also why when the video or reel is finished watching, the brightness seems to adjust back to the prior setting.Ĭurrently there does not appear to be a way to disable this HDR video brightness adjustment feature on Instagram or YouTube. The automatic brightness increases and adjustments when watching Instagram reels, videos, and some YouTube is actually because of those videos being recorded as HDR video, and how the dynamic range of those videos impacts the display. Automatically adjusting the display brightness while watching certain videos can be annoying for some users, and so perhaps you have already disabled auto-brightness in the settings on your iPhone to stop this from happening, and maybe you’ve tried turning off true-tone as well.īut, even with the system setting disabled, you find that watching an Instagram Reel, Instagram Video, and some YouTube videos, still causes the display brightness to change.
