N2 - Most international standards recommend the use of reference monitors in subjective testing for visual quality. But do we really need to use reference monitors? In order to find an answer to this question, we conducted extensive subjective tests with reference, color calibrated high quality and uncalibrated standard monitors. We not only used different HDTV sequences, but also two fundamentally different encoders: AVC/H.264 and Dirac. Our results show that using the uncalibrated standard monitor, the test subjects underestimate the visual quality compared to the reference monitor. Between the reference and a less expensive color calibrated high quality monitor, however, we were unable to find a statistically significant difference in most cases. This might be an indication that both can be used equivalently in subjective testing, although further studies will be necessary in order to get a definitive answer.
