Not necessarily. This is because the highest resolution of HD signal sources in the consumer market is recorded in the HD1080i (interlace) format. For example, HD content and Digital Broadcasting are actually recorded in the HD1080i format. The players de-interlace the signal into progressive through the built-in I/P converter to generate the HD1080p (progressive) format.
Basically, everything shown on LCD TV is actually in progressive mode. Even though for HD1080i incoming signal, the TV’s built-in I/P (Interlace / Progressive) converter converts the interlace signal into progressive before showing on the screen.
By contrast, HD1080p signal will bypass the I/P converter inside the TV and reproduce directly. Therefore, there is no significant difference in picture quality shown on the screen between HD1080p and HD1080i incoming signal because both of them eventually are shown in HD1080p format on screen. If there is, the difference lies on the quality of the I/P converter.
