While television refresh rates on both sides of the pond matched local grid frequency, did computer monitor refresh rates necessarily match? VGA for example supported 60 Hz but not 50 Hz according to Wikipedia [1]. So in the UK, I would think you could sync with fluorescent lights, or VGA monitors, but not both (unless you recorded at say 10 fps).
