We tested the Quick Media Switching (QMS) function on the Apple TV 4K (2022) box together with an LG G3 OLED. Quick Media Switching is an HDMI 2.1a feature that promises to eliminate AV blackouts, but only when the frame rate is changed, not when there's a switch in resolution or dynamic range formats. The "Includes Paid Promotion" message in this video refers to the sponsorship by Ultra High Speed HDMI Cable manufacturer Zeskit. If you're thinking about getting a new HDMI 2.1 cable, please support this channel by considering buying from Zeskit: https://zeskit.com/collections/hdmi-cable ======================== **Click Below to SUBSCRIBE for More Reviews, Sneak Peeks & Tips: https://www.youtube.com/channel/UCcCYOO2uYPnG-21WDOWdwew ======================== VISIT HDTV Test http://www.hdtvtest.co.uk/ FOLLOW US! https://www.facebook.com/HDTVTest https://twitter.com/hdtvtest https://www.instagram.com/hdtvtest https://twitter.com/vincent_teoh https://www.patreon.com/hdtvtest
