While testing this morning at the 3T using the goggles, I observed horizontal lines in the stimulus display during the functional scans. The contents on the screen were still clearly visible, but the pulsating lines were distracting. Has anyone else noticed such interference? Is it unavoidable?

The lines are always there, although their intensity varies depending on the pulse sequence. (you should notice some variation when a run starts and ends). I've never had a problem seeing the intended display when I've been a subject, though they are a nuisance.
