The incoming of high-definition new visual experience at home has boosted new display technologies such as liquid crystal displays (LCD), plasma and projectors. These technologies enable the increase of screen size necessary to feel a cinema-like experience. However, they introduce some new visual shortcomings not present on mature CRT technology. In this paper, subjective tests are described which highlight a difference of perceptual video quality between CRT and liquid crystal displays. Moreover, it's observed that this loss of quality on LCD is more important with high resolution sequences than with standard resolution ones. This influence of the resolution is particularly explainable for the LCD motion blur defect.
