Frequently Asked Questions
Why does Netflix keep the screen awake but IPTV does not?
Netflix uses Google's standard MediaSession API which automatically registers playback activity with the OS power manager.
Will leaving a stream on cause burn-in on OLED screens?
Static scoreboard graphics can pose burn-in risks on OLED TVs over hundreds of hours; modern OLEDs include pixel shifting and logo brightness limiters to protect panels.
