The user presses "Menu." The TV freezes for 8 seconds. Then it recovers. The user sighs. They buy a Chromecast. The Vestel becomes a dumb monitor. The firmware wins.

He opens a private tab. He downloads den's firmware. He extracts the panel_db.csv . Den fixed three gamma curves that the official team never had time to calibrate.
