TriField TF2 arrived home today. I measured magnetic field, electric field, and electromagnetic radiation from wacom cintiq 22. Magnetic field was less than 0.5mG on the glass surface and around cintiq 22. You shouldn't need to worry about magnetic field. There was no electric field at all near cintiq 22. Electromagnetic radiation between 20MHz and 6Ghz was less than 0.25mW/m^2 on the glass surface. To qualitatively measure electromagnetic radiation at 500KHz and 250KHz, I may need a portable AM radio, but I don't worry much about electromagnetic radiation from cintiq 22. If I'm worried, I can wear https://emfacademy.com/emf-radiation-protection-gloves/ and forget about electromagnetic radiation from cintiq 22. @thatcomicsguy I think that your pen display may contain an AC-to-DC converter inside it. Any AC to DC converter casts a strong magnetic field and a strong electric field around it. In addition to that, my desk inherited a fraction of electric field from adjacent AC-to-DC converters. After putting some distance between my desk and AC-to-DC converters, my desk stopped casting electric field around it. Perhaps, your desk is too close to AC-to-DC converters. In practice, just putting some distance between your desk and AC-to-DC converters should be enough. Also make sure that your gadgets are properly grounded and have no ground loop. Grounding errors multiply electric field a lot. When there was any grounding error, TriField TF2 couldn't measure electric field because electric field was too strong.
