Is Big W deliberately trying to discourage people buying TVs from them?

The key difference seems to be that the JB Hifi people know how to set up their TVs.

The Big W people don’t know, or don’t care, that on almost all of the TVs they have on display, the colour is completely distorted.

If you can’t see a display product working properly, why would you buy it there?
