Tony heard the call yesterday of a man getting a headache watching TV. He thinks the user is suffering from a form of light blindness, where the LEDs are too bright on the new TV. LEDs can dim over time, and he was so used to his older TV, that the newer one's brighter LEDs are giving him a headache. And TVs are set to be very bright on the showroom floor. So adjusting the brightness could help. Leo says you can adjust your TV to Cinema mode or movie mode, and that will adjust the TV to work best in low light.
