Yes, I have a PRO-1130 HD and the salesman is correct that the unit comes with a 3m cable to connect the receiver with the screen. This is a good thing because one can install the screen on a wall or wherever and have a single "umbilical" cord run from the receiver to the screen rather than countless cables (note: both the receiver and the screen have their individual power cords which are separate from the umbilical cord I mentioned). Pioneer makes two more cables: a 7m for $ 220 and a 10m for $600. Here is a link:

Maybe you can purchase these cables or their equivalent from an outside source but why risk it ?. This may only be worthwhile if you need a cable much longer than 10m. Remember too that a longer cable could possibly lead to picture degradation. You may also wish completely bypass the receiver and use the display by hooking it up directly to a source. If you decide go this route than you may want to consider purchasing one on Pioneer's less expensive commercial models.
Hope that helps
