Ycbcr Is the correct setting for movie playback.
Chroma upsampling is done either in LX500 or by the projector.
If you have passive hdmi cables well above 5 meters (16 feet) it would be better
to limit the amount of data transfered. Setting it to 4:2:2 probably is better in
this case, and letting the projector do the final upsampling.
Everything on disc is stored in 4:2:0. You could even send it with this setting
but hdmi does not allow sending 4:2:0 with certain video formats.
If you have short cables you usually choose the device that does the upsampling
best. For example Panasonic is especially good at this. Although Pioneer and
Sony both do a good job with upsampling.
Dynamic range on the projector should be set to limited, however strange
this may sound. Otherwise you will crush blacks and whites or get washed out
colors depending on settings.
For computer playback it is correct to set it to full.
Because of this it is mostly a good idea to have the display unit on auto
if you have several different types of sources.
