If, as you say, your issue is with the monitor, why all the blather about the computer?
The science, aside from the plethora of sites labelled EMFdoomconspiracy, suggests very few people suffer from problems with computer based EMF, that the actual problem hasn't enough scientific data to be verified and that there are a few ways of managing possible symptoms, (modern gear, good grounding, blue light filter software, time away from the unit etc.), if it exists.
Video player? Put a lid over it/tin foil/distance/human shield.
Overall, talk to your doctor or an EMF specialist, who isn't a conspiracy theorist, about your symptoms and your anecdotal, potential causal relationship pbservations.
