Apparently, some people can detect a flicker in such screens. Prolonged exposure for such people reportedly causes many of the symptoms of eye strain. Complaints seem to be more about the newer energy-efficient screens that have appeared during and since 2011. A number of solutions were suggested and each had its advocates.
- Set screen resolution to maximum. Smaller pixels mean the flicker is less apparent.
- Turn screen brightness up to maximum. That reportedly eliminates the flicker but creates a second problem – glare. Increased lighting behind the screen can help with glare.
- Attach an external monitor which has an LCD display.
- Some people also say that given time, their eyes adjust.
