https://www.youtube.com/watch?v=ZWea6pdOp-II found this video of 9 minutes, where the guy explains how to take practically ZERO EMFs from computers.
You only need to find bigger cables, buy a projector to project the screen on the wall, and put the computer and monitor in the next room.
the only EMF you'll get is from the LED projector (as it has to be in the room, somewhere), and the keyboard + mouse.
But if the computer is in the next room, and the computer monitor too, well, I suppose it will emit less radiation than watching old TVs.
He shows exactly what connectors / adapting cables he used. It does not look too complicated at all (and not expensive, plus you don't need to buy a new computer, nor a new screen!)
It works on lap tops too!
