The researchers noted, "Increased off-normal signal amplitudes were required to regain the detection performance measured for normal viewing. We observed this decrease in detection performance for off-normal viewing even when measured decision times were about twice as long as for normal viewing."

Badano and Gallas published their study in Academic Radiology (Detectability decreases with off-normal viewing in medical liquid crystal displays. Acad Radiol, 2006;13(2):210-218).
