That's correct. 1200K might not really be good as well so I usually set mine at 60-70%. I'm glad it helps. Cheers!

Hi, I have become very concerned about blue light, and finally found the Night Light setting in the windows display options. I set the strength to maximum, but am wondering, what percentage of blue light am I filtering at this maximum strength? 100%? 80%?
Thank you

Thank you for posting. I am Paulo, an Independent Advisor.
According to this article, starting build 15025, color temperature can go down up to 1200K (Kelvin). So if you set it to, let's say 100%, 1200K is the warmest color temp you could get.
