Computer Projector interference

Hello John. At my church the computer and projector are linked by UTP and VGA/UTP extenders. The UTP is around 90' long and for most of that length there's an induction loop around 8' above it. The projector would often blank and then rescan for its input during the service. We did two things:

1. Fed the projector and extender from a mains-suppressor 3-way adaptor.
2. Some tidy person had coiled up the spare UTP and hung it about 3' below the induction loop. I unwound the coil and spread it loosely on the floor. It's now rare for the projector to blank.

Hope this helps. Regards, Ian.
