While both are 42-inch 1080p screens, their timing controllers (T-CONs) speak slightly different electrical dialects. The PB802 update often contains revised "panel tables"—dictionaries of exact voltage timings (the VCOM voltage, the clock frequency, the LVDS/TTL data mapping). A successful update ensures that a screen meant for an LG panel won't exhibit a faint, ghostly purple hue when paired with an AUO panel.
