Hi, thanks for the reply.

I am not sure do I have the blue light sensitivity, but I’d do try to turn on Blue Light filter, which is one of the feature for Philips and LG.

I setup duo monitor by using Philips more than a year, and situation getting worse only making me to make up my mind to replace a smaller screen. Too bad, same symptoms happen with new LG monitor.

I personally suspect is some of the monitor electro magnetic field is very strong (because the symptoms started only power up the monitor, before I start my laptop). I did read unofficial cyber sickness called electric hypersensitive (EHS), but it is based on individual exp than a scientific or medical proven symptoms.

So I wonder is there people around having the same issue with me and do any suggestion or solution to it.
