TCO is the Swedish Confederation of Professional Employees or Tjänstemännens Central Organisation and TCO99 regulates the permissible electromagnetic emission from display devices . It parallels the provisions of the earlier introduced Swedish MPR II/MPRIII guidelines which also prescribe limits on electric and magnetic field emissions in the ELF and VLF ranges, as well as the electrostatic field .

Prior to the introduction of MPRII most monitors were power hogs and also had very high radiation levels . MPRII was internationally endorsed and supported, and revolutionised monitor design virtually overnight .

One major down-side was that the new low scan-energy design were much more susceptible to external electromagnetic fields and screen shake or shimmer was a major problem until wiring codes were updated to reduce electromagnetic emissions .

Strictly speaking the advent of LCD screens made both the MPR and TCO guidelines redundant, but they are now embedded as defacto limits and applied to a broader range of office appliances .

The other major down-side of emission reductions is that you can no longer find office girls hiding in the dark during power cuts by the green glow they used to emit . :D
