I am currently using Dell XPS 13 9310 2-in-1 as a business laptop on Windows 10 Pro version 21H2 and built 19044.2006. I connect it to a CCFL display Samsung B2240.
I use it daily either connected to the external display or directly and strangely it is fine. To connect to the external display i use dell's docking station.
I get tired eyes after many hours of work and mainly when looking directly to the laptop's screen. Very seldom i may have some migraines, again after hours of use without rest.
This laptop has the eyesafe.com technology, but i don't know if this is affecting anything.
It may worth to try, if i can use it perhaps it is ok for some of the people in this forum as well.
