Got a weird bug that is causing MY 50X90S TV to have major audio delay and input lag across all apps and inputs every time the TV is restarted or comes out of sleep.
The only way I can resolve it is to head to the HDMI Signal Format setting and toggle it from Enhanced to Standard, then back to Enhanced. It does not matter which input I choose to do this, just that it gets done.
I can also temporarily fix it by quickly turning the TV off and on - it's only when it goes into the "deep sleep" after roughly 20 minutes that the problems start.
I can only conclude that the HDMI Signal Format settings are not being correctly re-initialized when the TV comes out of sleep or restarts, and my workarounds perform the necessary initialization.
I am on the latest firmware and I have performed a factory reset, but it hasn't helped.
I believe this is the root cause of the issues I have been posting about regarding this TV ever since I bought it in 2023.
